Ok I need some answers not a debate on turbos vs. sc's

[grandprixgtp_91]

ok, now i need to know what kind of injectors i need for my gtp with a sc. how many lb per hour and what kind and where can i get them. also where can i get the computer chip i need? and should i use total seal rings? if so where do i get them at? also where can i get pistons that have the proper 9.5:1 compression ratio that is for my 5 speed? also what kind of fuel pump will i need and where do i get it at? and will a vortech fmu be required? also where do i get one. also what do you guys think of newengineparts.com? i dont trust it, there kit includes alot of 3.1L and quad 4 parts. thank you for any help you are willing to offer!

For 400+ you are looking at 42# or more. High impedence injectors stop at around 50# so thats as large as you can go. I have 36#ers and they are large enough that it has trouble idling since they are batch fired.

Send a stock piston off to a manufacturer and have them make up forged ones.

Vortech FMU, its up to you wether you need it or not. You got a MAP based system so even if you take care of fuel by some other means, you HAVE to worry about spark. The spark table is RPM vs KPa so whatever is in the 100KPa column will be used for ALL of boost. Bye bye motor.

ECM, since you got a 5spd you can get away with a heavily worked over TGP chip

I think it would take you about 13 to run the 1/4 mile. 13 hours, that is to clean up the pieces of the engine off the track. but DAMN while that engine held up itd run like nuthing, but for about 3 seconds. The crank would never hold, if the block didnt give out first. But maybe they would. Ive never tried putting that much power through a 2 bolt main. I'd sure give it a shot if I had the money.

soon to be 3.4TDC or 3.8SC???
Eventualy 350TPI....

Aren't there plenty of Fiero guys running boost on a DOHC? I think there are a few on Pennocks Fiero Forum. Also the 2 bolt main has been discussed. Most people think that going to a 4 bolt would be worthless because the DOHC can't make enough power to blow the 2 bolt apart.

[86FieroGT]

Im sure there are, If you actualy made 400 wheel HP, I bet thatd be pushing the main's to thier limit, I dunno, from what im guessing, its not going to be a daily driver, so what the heck?! have fun!!

I've heard rumors that the bottom end in the LQ1 is good for 600hp (not continuously though).

I am not saying the DOHC can't blow bottom ends, I am just stating what has been debated in another thread. I would like to think that some day my Z34 will be able to have enough power for me to worry about blowing bottom ends. That would make a fun car! I personally have not heard the rumors of the bottom end handling 600 hp, but would like to meet the people that have done this. That would rule!

[Lyle's GTP]

Does any body know anyone with a 3.4 car they want to blow-up. It would be interesting to see how much nitrous it could take before it blew. Then when it did/does it would be cool to see what parts failed. Somebody out there must have a junker. I've got a hundred bucks to invest in such an indevor.

I say 300 crank is safe, 400 crank on a stock motor isn't. Modified it might be somewhat reliable depending on how you drive it.

[grandprixgtp_91]

shit there goes my dreams!

Jake

I don't know about that. Compared to a 2-bolt 350, these blocks are much stronger structurally. There is guys putting 400+ through those things. As far as the crankshaft I think I heard that it has the same journal size as the 350 as well. If you had your components cryo-treated it would increase strength substantially. So if you up-graded your pistons and oiling system you sould be able to push some pretty good numbers. But seriously, has anyone even blown up a 3.4 by over boosting it, or was it engine wear?

ok, who voted that my car will run 15's? honestly, it runs 15's stock!

Why did you have it as an option then?

[grandprixgtp_91]

just to make it look better.
