would it blow up?
 

okay i already have 88mm intake &tb, and lid, lt headers with 3"dumps and i might be forgetting a few things but im thinking of buying a set of fully ported 243's and a ms3 cam and a 100 shot, do you think my motor would blow up? im not really sure how much power that would make but i heard that when you get to 600rwhp your living on borrowed time
thanks for any input

according to the ls1/ls6 book our bottom end (pistons and cracnk) are good for about 550hp. I have been doing alot of reading in books about building the motor, next is to do some forum lurking to see what everyone says that has the hp.

i am sure you will get more feed though, just something i have been researching. Alot more involved then i thought.

ya i just am tired of being so slow

i hear ya. . . . let the winter project brain storming commence

It all depends on you tune.

as in as long as its a good tune you think the motor itself can take it or i should go with a less aggressive tune?
thanks for the input

meaning if you have the right tune for your setup, your motor can take it... maybe not forever, but it can take it. if you throw the parts on and get a crap tune and it leans out, it will break, but it can do that bone stock...

replace rod bolts(esp. in a '98), and change/rebuild rocker arms(needle bearings FTL).

those will help a lot...on top of a proper tune...

with the hp and tq numbers in your sig, you should be in the 11s, so how slow are you are you sick of going?

mike, i make 425rwhp... and ran 12.79 lmao. i blame suspension setup and bald street tires. maybe there a similar variable in his case.

ok, so in that situation, would you add a blower? point being, he is making respectable numbers in a situation that is safe for his engine, so... rather than 5k on a blower, spread it around the car.

i agree, no sense in making the engine more powerful if you can't plant whats already there.

With that 4000 stall TH400 and your suspension, you damn well be going 11.80 or better...

And why get an out of the box cam that will have you spin your lousy 98 bottom end to the moon to make any kind of power...?

we can make it last :)

thanks for the input guy ill have to call jasper tomorrow and see if they can tell me anything about the motor

nah, i meant it as in he should look to see why hes running "slow" first and address those issues before trying to just add more power.

its not that im having traction problems i just want to go faster

Tell me how fast you wanna go and I'll let you know what you need to do:twisted:

Tune and suspension are the biggest factors in going fast. If you have a crap tune it wont matter what you have done to your car. It wont run like it should. If you have a crappy suspension then you wont run what you want anyway. 1st mod I did to my 02 WS6 was SFC's. If you want to build a car that will see a ton of track time I would suggest Suspension and a 9 inch rear as your 1st mods.

i have kyb agx shocks and 325# springs up front, stock springs with the comp. engineering 3 way adjustable shocks in the rear, weld in sfc's, and im gonna buy a roll bar i forget if i have anything else suspension wise, i also am either gonna finish the 8.8 rear or just buy a 12 bolt(if that wont break), and i have UnnamedShop1 performance tune my car( i trust them with it completely)...is there a lot of other suspension stuff i am missing?

Drag bar/sway bar in the back helps alot with roll.

Lower control arms/tq arm are a must.

i forgot about my lca's and i was just looking up on the drag sway bars and thinking of getting one theyre really expensive though so i wanted to find out how good they were before i bought one but looks like ill be picking one up now thanks for the reply

It all depends what you want to do with the car...

I have a UMI drag bar on my car... nefore that I ran the Spohn bolt in stock location bar which worked well too.

Also, 325# springs in the front seem a little stiff...

i say F it lets find out!:wink:
