my91rs

why is the turbo going too be sitting under the car? Thats just the way I m picturing it.

Guido

It doesnt.

Vicious 88 GTA

ok now I am lost, how does a turbocharger really work, please explain it to me in lamen terms. and what kind of six is that a 3.8 or a 4.3? AARON

JC93Z

It is a 3.8 liter Grand National motor.

Turbo operation.....Exhaust gases spin a "blade" that is connected to another "blade" which forces cooler air into a tube through an intercooler or just directly into your throttle body which does the same thing as a supercharger ( pushes air into the throttle body ). The exhaust air that was used to spin the exhaust blade is spent through the exhaust. I am not too good explaning it I just know how it works...LOL

Is that the turbo you can turn on and off through the switch inside the car?

JK! The archives have a ton of syuff on there about forced induction, it'll give you a couple things to research..

jesse23

where did u get v6 headers?

SATURN5

Ummmm..... Those are an example of Guido's excellent fabrication skills. <G>

Blockhead

Didnt you see the photos of where the headers were tack welded together? Maybe we should trade names. Ill be jesse and you can be blockhead. What do you think?

Greasemonkey

Ahh, the return of Blockhead.

Just out of curiosity, what're the goals for the car? What all's being done to the engine, ported heads or anything?

Alright Guido !

I'm doing the same thing on Project 2.8 The only difference is i'm using a single turbo setup. I'm running them into a merge in the front of the engine, then running the exhaust end right on out the passengers side, beside the block. I've got a 3" intercooler so far along with a couple of t-3 turbos, BOV, etc. I've just gotta wait on the engine buildup before I rip apart my wifes car

This gives me a great idea on how to run the headers now. Seems to be easier than what most people think as long as you know a good welder

Goals for this set-up in the car:

I hope to have at least a mid 10 out of this set-up. I don't forsee any problems of getting that goal. Then when I put two TA-49's on the car I would like too see a high 9 second pass.

The engine is a SG1 block. It will have steel mains, RJC girdle, stock rods, stock crank, forged pistons ( around 8.5-9 to 1 compression) 70 mm throttle body and pleneum. Highly ported and polished irons. Erson cam, lifters, springs ( got it cheap so I figure what the heck), probably Jesel or T/A rockers. Remote oil filter location. FAST or DFI. Alchi injection......

Hey Jc93z, what type of cam are you going to be using? from what I understand, the roller cam makes 100 hp over the stock style.(that what Dan from PTE told to me). What about the trans, are you going with the 200r4 or the TH 400? I think it is better to build a TH400 with brake to launch hard with those two 49's to hold up in the long run.I also understand that the oil return line has to be done right in these Buick motors due to oil foaming issues, if you are draining right into the pan. Why did you decided to build a twin turbo to run only in the 10's? Do you have plans to build a stage or TA block down the line? I was able to run 10.70's @ 124mph in a 3800lbs car on a single turbo and 23lbs of boost. My combo was stock bottom end, 212/212 comp cam, GN1's with street port work and port matched intake,PT70 turbo w/.81 exhaust housing 4" downpipe, race gate .huge FMIC, DFI, 55lbs injectors, full race trans with N/L Art carr 9" and the basic fuel and suspension modifications.Now that I am done with pushing the stock block into the 10's I am in the process of building a on center stageII block. Your thoughts?

Good luck

Rack and pinion steering in a 3rd gen- now that's something you don't see every day.

Oh, and nice turbo thingy setup. That's cool, too. Heh heh.

NTChrist

That could have something to do with the fact that it's not a third gen.

MdFormula350

nice looking setup!

JC93Z

WTT, Right now I am going to be using an erson 214/214 cam, just because I got a good deal on the cam, lifters, and valve springs.

What I am actually wanting to do is get the motor just running right now, so I can drive it. I won't even have GN1's just yet, I was going to do a little port and polish job myself. I will also be using two stock turbos right now. This is the set-up I want to run 10's with. I was being cautious with assumption. I know the car will go faster then that. I just didn't want to say something and then people bash you if you don't reach your goals. I always set my goals low and if I break them then that is great!!

I am using the current TH400 I have and I am going to put a break in it.

Final plans with this motor, it will be in the 9's on until it breaks. The motor will have two 49's on there, a set of ported and polished GN1's, etc. you get the idea. Then after this motor I do infact have plans of building a stage motor with twin 76's on there.

If you have any other questions comments or suggestions to help with the car I would appreicate it. You can send an e-mail to n20psi@hotmail.com

Thanks,

so what kind of car is that? its deff. not a thirdgen buy looking at the engine bay.... and i dont think its a GN cause teh car is blue... it is deff. a late model, RWD car. im looking at the brake booster and i see that the resivoir is all plastic... im so confused and i have no idea what car that is... or is this all hush hush?

edit: nevermind.. i saw the rear tail lights..... nevermind

Greasemonkey

His name is JC93Z.....93Z.......

Anyway, with respect to the roller cam adding 100hp, does Precision really have any numbers to back that up? I remember when I was there for the open house a couple months ago somebody saying that a GT turbo could give you 100hp and a roller cam could give you 100hp. For some reason I don't really believe that. Just wondering if anybody here had any input on that.
