carb swap!

[maroman88]

well i wanted to do an LT1 but timing and funds wont allow, sooo

im sick of my TPI giving me problems, i wanna go carb!
its going to be on a stock 305 motor, was originally a TBI.
wat kind of manifold, carb, distributor combo works best and is cost effective?
do i have to change out the tpi fuel pump or is there some type of regulator?

looking to start this project ASAP

[bubba428]

if you want I have a CCQjet with intake and full UNCUT wire harness and ecu

[madness410]

what kind of problems was your tpi giving you if you dont mind me asking

[BonzoHansen]

I have a standrd performer intake here somewhere I'd sell you on the cheap - good for a 305. Standard head bolts.

Other things I think you'd need: a standard hei dizzy, fuel pressure regulator, fuel line, air cleaner housing & filter, t-stat housing & gasket, upper rad hose, throttle cable, choke wiring, maybe a vac fitting for the brake hose, a fan switch if yours is ecm controlled now, intake gaskets, coolant, ...I'll keep thinking about it....

But I'd rather have EFI. What's wrong?

[maroman88]

i never got the TPI to run right, replaced everything 3 times, im bored with it, i wanna learn about carbs, new project........

i took a summit catalog to work with me over night last night and picked out a few things, when i wake up later ill post up what i liked so far

what should i do with the wiring harness? remove it and wire up what i need?

[Tru2Chevy]

You can remove any wires that come from the computer into the engine bay.

That ebay auction will work fine. I would stay away from Edelbrock carbs, go with a nice simple Holley. Also, that manifold you posted will work, but considering the cost, I would talk to Scott about what he'll let that Performer he's got go for.

yea thats what i was thinkin, i kinda feel bad destroying a perfect TPI harness tho lol but ya gotta do watcha gotta do!

ok but whats the deal with the "standard head bolts" is that for the pre-87 style heads? i was lookin for one for the 87-95 so i wouldnt have to drill out the bolt holes

[Jersyboyy]

Im picking up a performer rpm intake. When I get that you can have my performer 2101 intake for 25 buck!

[Tru2Chevy]

yea thats what i was thinkin, i kinda feel bad destroying a perfect TPI harness tho lol but ya gotta do watcha gotta do!

Why destroy it? just pull it all out in one piece and keep the setup or sell it whole.

- Justin

[maroman88]

Why destroy it? just pull it all out in one piece and keep the setup or sell it whole.

- Justin

well arent i going to need some of the wires? like to the starter and alternator, AC and watever else, the whole thing that comes out of the driver side firewall... i was guna buy a cheapo harness from a carbed 3rd gen or even a TBI car and cut out what i dont need, this way i can sell the TPI harness with the TPI set up

[Tru2Chevy]

Hmm....maybe the TPI harness is different than my LG4 harness. I was able to yank everything that comes from the computer in mine with no issues. The HVAC wiring and battery/starter/alternator stuff was separate.

- Justin

[Fast92RS]

Yeah my tpi harness is all one peice to seperate it you would have to cut it up. I think you would be better making your own harness or buying a harness form a junk car or maybe a painless, either way your gonna have to custom wiring.

[nj96z28]

i remember my '85 iroc... that tpi was PoS , given I beat the snot out of it but i blew through 3 egr valves .

Go Carb Conversion, be sure to match your intake and tuning :)

[maroman88]

hmm would a 3rd gen carb'd fuel pump be the same as a TBI fuel pump... i know the TPI's like wayy to many psi so i gotta change it out

[Tru2Chevy]

3rd gen carb cars used a mechanical pump. You can leave the TPI pump in place, you just need a return style regulator.

- Justin

[maroman88]

so this lil guy? and what else should i invest in to make her work? i wanna place one order from summit for all the fuel needs

http://store.summitracing.com/partdetail.asp?autofilter=1&part=MAA%2D4309&N=700+115&autoview=sku

[maroman88]

hmm what size are the stock TPI rubber fuel lines, so i can buy the fittings for the regulator... -6AN?...

[WildBillyT]

hmm what size are the stock TPI rubber fuel lines, so i can buy the fittings for the regulator... -6AN?...

They are probably not AN threads. You are probably looking at 3/8" line size with NPT threads.

[Tru2Chevy]

They are probably not AN threads. You are probably looking at 3/8" line size with NPT threads.

Bingo.

- Justin

[maroman88]

ok im at a loose here right now. im guna order the mallaroy 3 port regulator, its inlets are 3/8in NPT female, the stock TPI rubber lines are also 3/8in NPT female, now i cant find any NPT male to NPT male adapters anywhere........

[WildBillyT]

If it's rubber, can't you use a 3/8" NPT barbed fitting?

[maroman88]

it has 3/8in fittings on each end already and its at ~50psi

[WildBillyT]

You need a 3/8" NPT pipe nipple.

Like so:

[maroman88]

niiiice thanks! couldnt find anything like it on summit

[maroman88]

and for my next question.....

how should i go about wiring up the dual electric fans

[BonzoHansen]

Search the electrical forum, there are a bunch of diagrams....are your current fans wired as per the factory? If so, is that ecm driven or switch driven?

[maroman88]

yea the ECM tells the TPI fans wat to do. i removed the tpi harness from the car but left the fan relay and harness for now until i figure out wat im guna do. i bought a TBI harness to hack apart and use but they only had single fans and i dont remember if the ECM controls it on a TBI car or not

[BonzoHansen]

Good. You just need to use the wires that ran from the ECM to the relay for the trigger circuit(s).

Simplest way: Get a fan switch, put it in the side of the RH head, connect the lead from the new f/s to the ECM wires at the relays - the 1 wire will splice to both --> "Y". I believe you should still have power at the relay (trigger & feed). If the trigger hots were cut then you'll have to run IGN power to them.

You could also run each fan on different switches for a lower & higher temp setup. Best is add a 3rd realy and run both at 6 volts from a lower temp switch and both at 12v off a higher temp switch. How complicated do you want to get?

Do you have AC? Do you want a manual override switch?

What car/year/engine are the 2 harnesses (TBI & TPI) you have from? I will look it up & draw a pic for you by Sunday night.

Cut as little from the ECM harness as possible (resale value)!

[maroman88]

the fan harness is from an 87 GTA and the new tbi harness is from an 88 camaro, i have AC

[BonzoHansen]

You have 2 fans?

[maroman88]

yes sir

[BonzoHansen]

So there are 2 fan relays? The 87 TPI diagram I have only shows 1 fan

See if this is what you have....

[maroman88]

hmm ill have to check on the relays.... there are 2 fans, one main and one when the AC is in use

[IROCdan330]

There are 2 fan relays. one is on the side of the rad support...one is up under where the passenger headlight is...

one fan runs off of the ECM telling it to...the other runs off the swtich in the passenger head.

been a little bit since i last messed with it, but i believe if you ground each of the relays to chassis ground, then put a switch in line...they should both work with key on power. the one that runs off the pass. head switch definitely is like that, and im almost positive the ECM only ground the primary fan relay, so it should also work like that.

[BonzoHansen]

Given all the changes to the car I don't want to assume what is actually there. He says 87 TPI harness, but the diagram I have for that is 1 fan. Same for 88 TBI. But my diagrams could be wrong too.

In either case, I think he can just use the dk grn/wht lead from the ECM (yes, the ecm supplies ground, as do the fan switches), but run it to a fan switch. the 2 fan setup appears to have a fan switch in the head - you could use that lead and both fans come one at once, or get a cooler temp switch, install it elsewhere, say the t-stat housing, then that one will come on sooner.

[maroman88]

one relay attached to the fan harness, but there was another one mounted in the same area but that was attached to the engine harness.... and this is in the radiator, and was used with my old TBI harness but not the tpi harness, im thinking either a low coolant sensor orrr a fan switch?

[IROCdan330]

or something to do with trans temp.

[BonzoHansen]

one relay attached to the fan harness, but there was another one mounted in the same area but that was attached to the engine harness.... and this is in the radiator, and was used with my old TBI harness but not the tpi harness, im thinking either a low coolant sensor orrr a fan switch?

I don't think it is a fan switch (never saw a gm one like that) or low coolant switch (seems too low). I dunno - I can't find it in any diagram (is that rad original to your car?). :shrug:

See if the fan harnesses you have matches one of the diagrams.

[maroman88]

yea that sensor was plugged in on my old 88 TBI harness, when the new TBI harness comes ill have ti see if it plugs in

im guna say it looks closest to the first diagram u posted, but with only one relay on the harness itself... wierd

[Tru2Chevy]

That looks like the coolant level sensor that was on my '91 Lumina, but it does seem kinda low in the radiator.

- Justin

[maroman88]

You need a 3/8" NPT pipe nipple.

Like so:

http://www.hrpworld.com/index.cfm?form_prod_id=36,24,317_409&action=product

great..... so i bought 2 of these for the inlet and return from the regulator, only to discover that the return TPI hose is one size smaller (1/4in i guess). so now i need a 3/8in NPT to 1/4in NPT double male, and i cant find one, hell a 3/8in female to 1/4in male would make me happy lol why cant anything be easy???


EDIT...how about if i cut the ends off the stock lines and use these...
http://static.summitracing.com/global/images/prod/large/sum-g3116.jpg

will it hold up to the pressure with some sealant and a hose clamp? mainly need it for the return

EDIT#2...got the carb and the wiring harness today... been one of those weeks, the electric choke was smashed to pieces in shipping

[maroman88]

installed the new distributor. need to wire it up. my engine harness has a thick red and white wire on one plug (that used to go to the coil) and the other plug is purple/white, tan, black and brown?(used to go to the old distributor). comming out of the new distributor is a red, black and brown wire....

what do i do?

Use the wiring diagram here to confirm what wires are what.

I rewired mine a few years ago and don't remember.

k cool

guna be black/red purple/white white tan/black on one
pink and white on the other

[BonzoHansen]

A standard HEI dizzy is 2 wires - IGN hot (IIRC pink) and tach lead (brown).

My guess is the wires you need are already there.

And your cap is likely facing the wrong way to get to the wires. Although I guess it matters not as long as you put the plug wires on right.

[Tru2Chevy]

I'll try to remember to get a picture of mine tomorrow morning for ya....

- Justin

[maroman88]

bonzo.... i have those 2 plus a brown wire coming out of the dist, the cap itself has no wires coming out of and it i made sure the spark plug wires are correct

justin... thatd be fantastic!

[BonzoHansen]

There should be a small harness that comes out of the dizzy and plugs into the cap - you have that?

[maroman88]

http://i21.ebayimg.com/06/i/000/f1/45/8263_1.JPG

this is exactly what i have, and there is a place on the cap for wat looks like 2 plugs....

[maroman88]

i think i got it figured out.... the plug with 4 wires was for the ESC, which i dont need and the other plug with 2 wires is for the batt and tach terminal on the new cap

[Tru2Chevy]

i think i got it figured out.... the plug with 4 wires was for the ESC, which i dont need and the other plug with 2 wires is for the batt and tach terminal on the new cap

O and BIG tip on dizzy install make god dame sure that your at TDC with the #1 cylinder or when you go to start it that nice shiny new carb is going to have the power valve blown to hell

[maroman88]

hmm wats a good ignition keyed 12volt source near the electric choke? for the electric choke lol

[maroman88]

k i found a keyed power source..... someone care to explain how this electric choke works? i wired it how it says on the directions but it just gets really hot....

also.... the fuel pump primes and has about 6-7psi after the regulator but after it stops priming it drops to 0 and the car wont start, just cranks. i was reading about wiring a keyed 12volt wire to the gray wire going into the relay to keep the pump on? if that makes sense

[BonzoHansen]

AFAIK the choke should just get IGN hot. Huh.

On running, the fuel pump relay circuit is completed by the oil pressure switch. Is that still hooked up?

[maroman88]

for the choke it says "Red Wire: To ignition key activated 12v source (not coil or alternator)"

oil presure switch is just above the oil filter? and yes thats plugged in

[maroman88]

it seems the reman dist i bought blows! i cant get spark most of the time, ive gotten the car started a few times and then i loose spark, ive taken the whole thing apart, checked the ignition module on my tester, greased all the conections and put it back together..... still nada, a lil spark here and there, leads me to believe a bad coil.... due to either a little or no spark, watta u think??

[Tru2Chevy]

Sounds like it's time to swap the distributor for another....

- Justin

[maroman88]

okay well still no start with another dist. im at a loss.... i got it started twice last week for a short time, but now nada. im guna pick up another battery at some point, im sure the current one isnt in the best shape after all this cranking and charging, maybe play with the dist placement..

[sweetbmxrider]

you have spark and fuel pressure? and you installed the distributor at top dead center?

[maroman88]

k, reset the distributor in the right position... adjusted the fuel pressure to 5psi, cleaned all the spark plugs....

now when cranking nothing. if u floor it and crank it gas shoots up and sometimes fire! out of the carb.... somethings not right lol

[Tru2Chevy]

Are you 100% sure that the distributor is in correctly? Anytime it's backfiring out of the carb you have to consider that the distributor is 180* out....

- Justin

[maroman88]

hmm duno how to tell that? i used the finger over the #1 plug hole while cranking it and set the rotor accordingly

[BonzoHansen]

hmm duno how to tell that? i used the finger over the #1 plug hole while cranking it and set the rotor accordingly

Do you have a timing pointer on the front of the engine?

Like this:

http://www.hotrodders.com/journal_photos/00020668/11436582212.jpg

- Justin

[maroman88]

why yes i do have a similar looking item covered in rust on my engine

[Tru2Chevy]

Use that to verify that you're at 0*....the balancer should either have numbers marked out on it like the picture above, or a notch where 0 is.

- Justin

[maroman88]

yea ok i think its got a notch... the timing tab is different tho, its rusted over so theres no markings but its got a cylinder shaped thing on it..... ill try n get a pic tomarrow

[maroman88]

ok so i swung the dist around wat looked liek 180*, it actually tried to start! bumped the dist one more spot forward and now itll start if u keep the pedal to the floor while cranking, and will idle very rough and blow out allll kinds of smoke if u keep on the gas a little, but once released it stalls

[bubba428]

not enough advance/retard....does it back fire and or pop from the carb? or does it stumble

[Tru2Chevy]

Yea, sounds like you have the distributor in correctly now, just needs to be timed.

- Justin

[maroman88]

fiddled around with the dist some more, got it to idle, still a good amount of smoke, but less then yesterday. gas gauge at E and im not gettting a reading on the pressure guage so ill have to get a can of gas tomarrow lol, that might explain why it wants to stall when revved!

[maroman88]

update!

got a 5 gal can of gas... now im actually getting a reading on the FP guage....

start the car... got it to run awesome! then the carb floods and car stalls. i lowered the regulator down to 3psi, as low as possible, and the same thing accurs....

i went back to all the paper work that came with the regulator and noticed it says the return line should be equal size or larger the then input line (from tank to regulator)... well the stock return line is one size SMALLER then the input line and it appears that the fuel is just backing up and pouring into the line to the carb.

if i pinch the line running to the carb and release as fuel is needed it will run perfect, but if i leave it alone again it floods and stalls...

i didnt read about this problem anywhere from the tpi to carb swap sites.... maybe since my car was originally TBI it had a smaller return line then TPI cars???

if thats the case only thing i can think of would be to pop in a TBI pump since they only run at 15ish psi IIRC as opposed to the 50ish psi for the TPI pump, thus allowing the regulator to not get backed up with the smaller return line..... if that makes annnyyyy sense lol

[Jam]

Fuel Injection for the win. The most reliable fuel system <3

[sweetbmxrider]

why can't you put in a larger return line and be done with it?

[maroman88]

Fuel Injection for the win. The most reliable fuel system <3

thanks for the help........ if u read the begining ud see i wanted to learn sumthin new, i did TBI and TPI on this car already....

why can't you put in a larger return line and be done with it?


all the way back to the tank? i think itd be easier to pop a new lower pressure pump in, and prob cheaper

[sweetbmxrider]

easier, probably. cheaper, depends on your resources. if you think it will work and not give you problems down the road, by all means do it! i'd hate to see you backtracking and throwing money out for nothing. post up how it goes.

[maroman88]

so i was told to check on the floats in the carb... losened up the top piece and played with them, appeared fine, bolted it back down, problem still there....

removed the entire top of the carb.... only to find one float FULLLL of gas and one of the seams opened up, that would explain it not floating up and shutting down the fuel delivery and causing it to flood... right?

i found new floats on summit for like 14 bucks, guess ill be ordering them

[WildBillyT]

How old is the carb? Does it have metal floats or plastic?

[maroman88]

brass, no idea on age altho its extremely clean and all the gaskets look new

[maroman88]

ok new floats in, runs awesome! i actually drove it around the block :)

but now of course new problems arise! alternator not charging! checked the volts everywhere, all equal at 11.70 and all droping at the same rate while the car was running, guage in the red... time for a new alt!
oil leak like a mofo i think coming from the oil filter, needs an oil change anyway!
cooling fan not coming on/HVAC blower motor not working.... i looove wiring!

[Fast92RS]

I'll have to look at the wiring for the alt. and post it up but make sure you didnt cut any wires that go to the connector on the alt and make sure the power output from the alt is going directly back to the battery or to the little terminal (stud) mounted on the battery tray on the side of the battery.
The problem you are having is going to be chasing down all these wiring nighmares becasue of trying to reuse the factory harness. Your best bet would have been to completely rip out the harness cut out all the fuel injection parts and pretty much rewired it from scratch. Alot of the things your trying to reuse were controlled by the ecu. Such as the cooling fans.

QFT I bet that alt is working fine but not wired right.

You dont want to buy a new alt and give them a perfectly good working alt core, I know I did that traded my 100 amp alt in for a smaller one because I need it to work to get back and forth to work. Turned out it was the battery and the alt wiring!!

[maroman88]

i didnt hack up the herness at all, i cut out 4 injector wires, the air pump wires and one other thing, the rest is all there still, with the ecu plugged in...

[Fast92RS]

Thats OK that you didn't hack anything up but even if you still have the ecu hooked up its still not going to control anything because its no longer getting a signal from the module that was in the distributor to say if the car is running. So as far as its concerned the car is not even on. You can pretty much just disconnect it.

[maroman88]

does the alt even have anything to do with the ECU, i plugged in teh scanner and the ECU is showing 11.9 volts and it still has a coolant temp reading... all the alt wires look good too

[bubba428]

cut the red wire on the 2 plug connector and run it to a keyed power source. problem solved

[maroman88]

cut the red wire on the 2 plug connector and run it to a keyed power source. problem solved

but im already gettin power on the wire....

[bubba428]

which wire? the 2 prong or the single wire that bolts to the back?

[Fast92RS]

on the weather pack connector do you have 3 or 2 wires? If its 2 wire then pin F is a brown wire and is from the fuse block with a 20 amp fuse, on my chart its the same fuse as the fan fuse. Pin S is a red wire that has a fusible link that goes to the starter. The ecu is not connected to the alt.

[BonzoHansen]

Hold on. What harness is in the car now?

This is the alt & starter WD from the autozone site for 88 Camaro body harness, I added color. Chk that fuse, chk those links.

bingo! lol so the alternator not charging has nothing to do with the ECU!

lol bonzo its now got a 90 tbi harness... gets hard to keep track of!

[BonzoHansen]

LOL, I can't keep up. But what I posted is 88 body harness, not sure if you swapped that. I'll check the other too.

Edit: 90 body harness shows the same ALT circuit I posted above.

IIRC, if that brown wire is not energized the alt will not 'turn on'. I could be wrong. For the link you need to check for continuity from end to end.

[maroman88]

yeap. brown wire has no power.... i traced it back as far the the rear ps valve cover, and checked the fuse... is there a ground somewhere? my fans not turning on either...

[Fast92RS]

Yeah that brown wire is power for the fans and the alt. It gets power from the fuse box. Did you accidently cut it and use it to power your dist or electric choke?

[maroman88]

haaa it turned out to be wat i suspected!.... the 90 harness is different from my 88 fire wall connector. the brown wire went to nothing! i tapped the brown wire to an emmisions wire im not using and the alternator was charging...

now, can i move that wire to a diff spot on the firewall connector, maybe group it with the fan wire, since thats where its moved to in the earlier cars, orrr try and find an 88 camaro tbi harnes?

Yeah you could move around the pins in that connector to match up to your car. If that does not work then get another harness.

[BonzoHansen]

Is it safe to assume your blower fan does not work right either?

[maroman88]

Is it safe to assume your blower fan does not work right either?

nah actually just fixed that.... the hvac wiring was slightly different... i may just find an 88 harness after all.... the 90 has no windshield wipers in it, its on the headlight harness and the pins dont match up either...

thanks everyone! im sure there more probs to come tho lol

lol until i find an 88 harness, i tapped into the old air pump wires i had cut out.

car runs pretty good, took it for a quick spin yesterday!
still needs some finishing touches like....
get the timing set
carb tuned
still have one fuel leak from the regulator
get tthe kickdown cable to stay attached to the carb!
and other small stuff
