Im going with the Abbott's N/A cam, and the engine's been bored .030 over, I know right on the edge, but there's no F.I, or NOS being used, so I don't worry too much. I have powdered forged rods waiting to go in, and the heads I believe I'll go stage 1 or 2 with abbott. Also I went with Speed Pro pistons

I was sprayin a 125 shot on my bored out 3.8 and it loved every lb of N20!! Untuned on the gas my car made 370rwhp. Abbott wasnt around when I built up my car. The only heads and cam company was Super Six motorsports and there wasnt even a stage 2 or 3 either. If you dont mind me asking why use forged internals if you plan on staying N/A? I am just asking because I know how pricey they are!! My Car had High compression Diamond forged and coated pistons with Forged L32 rods and a custom Crank. Cost about 2000.00 for the rotating assembley. I did all that because I was running N20.

i need someone that can tune my ECM to read boost for bigger injectors a bar 2 MAF and a wideband O2 but can't find anyone that will touch a 92 firebird computer

no forged pistons, just teh powdered forged rods. the deck was milled to be flat, the heads are goign to be milled, and Im goign to run thin head gaskets from cometic, so I'll be around 9.6,9.7 C/R. I was aiming for 10.0, but too much stuff would haveto be modified, and the heads would be weakened to do that, and 10.4 pistons are out of my budget. It's nto so much the C/R that I was worried about, but I'm settign it up to be a road race applicable car, so to make up for the missing torque, like most small litre motor's im tryign to apply more RPM to it, and our motor's are a little skimmish past 6000-6500 because our oil ways are a tad too small. I'm havign the oil passages opened slighty, and I'm using intense's oil pressure kit to boost it up from 55lbs. to 85lbs to ensure there is oil there in the higher RPM's, I believe that was one of the flaws that scrapped my last block.

I had that intense oil pressure kit on my built motor. It didnt do a damn thing. Still had stock oil pressure. My Cam specs were 210in 220ex 534inlift 547exlift with a 112 L/S.. I had 10.1 compression ratio. You will want some light weight top end componants also. I used comp springs with titainium retainers. also I had Manley light weight valves and intense racing pushrods.

The heads from Abbott are usually pre-assembled with #130 springs and retainers. I was looking to go 10.0 on the C?R, what did you do to achieve that? I also purchased the light weight pushrods and comp cam racing lifters for that setup. and before I'm asked, yes I got the double roller set, and I have to send out the crank sprocket to match the original crank sprocket sine they are built for the Aussie cranks.

Did oyu have your oil bypass sealed? that's something that's a must for our engines.

My v6 had a mail order tune.
Tuned specifically for nitrous (timing wasn't advanced as much as an n/a car)
It was dead on A/F for N/A
With a bit of jet changing, it was dead on on the bottle.

My v6 was far from stock.

Didnt you only have ported heads and bolt ons on yours? I remember watching your car run at those V6 meets every year in Maryland. I went the one year with Stefan ( The Virus) and Jenn ( Pathogen ) when she still had her Camaro!

The heads I had milled down by my machine shop and I got The High compression Diamond pistons. The CR was around 10.2:1.. My pistons alone were around 1000.00 dollars..

I tried a mail order tune but my car wouldnt even run on the PCM for less tune. I sent it back and they sent another and still my car wouldnt run with it! I kept my stock PCM and used Maft translator Plus to tune the A/F and timing.

As far as the oil bypass thing I dont remember. It was a spring kit for the Oil pump. I didnt have a double roller timing set.

Yeah, I'm using stock compression pistons, so it's only going up a few for the C/R, nothing too major. When you mean it wouldn't run on your tune, was it just cranking, or was it running, but so crappy you didn't wantto move it an inch, cause thats what I'm talking about, I don't want to do a mial ordr tun, cause you have to wait to get it back and you don't know what they did, and if it'll work.

We did the motor in my car with the stock PCM. I started up and drove fine. Sounded really good with the cam. I then got the PCM from PCM for less and installed it in my car and when I fired it up It ran like crap!! I let it idle or tried to let it idle for some time but it kept on dying. I called up the company and they told me it should work fine. They suggested to send it back to them and they will send out another. They other one did the same thing. I sent it back to them again and just gave up on it. I sent them a list my mods and they built a tune around what I had done. Of course this was 5 years ago so I am sure they have gotton alot better with V6 cars.

Wow, that's messed up. I know when I sent my computer out, I asked for firmer shifts and what not. I got it back, and they did change my rear gear ratio, and lifted the speed limiter, and rev limiter, but as for shifting, felt like normal. I was pissed.

Did you have a Crankshaft Position System Variation Learning Procedure done on the PCM that came from PCMforless? If not that might have been the problem. If the PCM is changed, the learn procedure must be done for the PCM to interpret the crank trigger properly. If you sent them the original PCM for a tune, then it was not needed, UNLESS the crank shaft pickup was replaced or removed/reinstalled.

I specified "slightly firmer" shifts. It came back firmer on the 1-2 shift and only slightly firmer for the others. I'm not that impressed with modifying PCM parms to get the shifts firmer, although it obviously worked on my tune.

Eventually, a shift kit will be installed and the PCM set back to factory spec.

i got a shift kit for sale for our 4l60e since im going T5, new in box.


And I forgot about the learn crap, good point.

There are many reasons you'll likely NOT find anyone that will touch it. All of those reasons are good ones as well.

Bolt ons, alot of bolts removed, spray, gears, TC more than likely, etc. You make it sound like he had a CAI & catback :lol:

You don't run low 12's in a v6 firebird with a few bolt ons.

Your right!! You runs low 12's in a V6 with bolt ons, weight reduction and N20!

I should have been more specific. I was refering to his motor! I believe his Motor had the stock cam, stock internals with ported heads with headers and the usual bolt ons!! I think James car dynoed @ 180rwhp on motor if I remember correctly!!

I dont remember. That was 5 years ago! All I remember is that I told them what Mods I had and they sent me a PCM then I was suppose to send in my stock PCM..
