I have a 2000 trans am, I put a d1sc procharger kit on with the upgraded intercooler. I have also installed bigger injectors and bigger fuel pump. The engine itself is stock the only other mods are edelbrock shorty headers and slp cat back. It has a spec stage 3+ clutch and spec flywheel. Where should I go from here? Pushing 9lbs. boost I know its only the matter of time with my stock bottom end. The guy I bought the d1sc from also had a blower cam and ross forged pistons that I also bought. Should I keep my ls1 block and build it or should I go to a 6.0 iron block? Any ideas?

 

I would open up the exhaust. 1 7/8 long tubes, 3" y-pipe into a Mufflex 4" cat back. Or you could go true duals. Bottom line, your current exhaust is a restriction and opening it up somehow (even cutouts) will likely net the best hp/$$$ ratio.

 

Make sure you do exhaust before cam. What size are the pistons? if they are 3.905 or so pistons, then build the LS1. If they are 4.0 or bigger then do the 6.0. Seems like the D1SC likes the smaller cubed setups better from everything that I have seen. Also, the additional cubes from the Iron block will come with a weight penatly that will likely cancel out the power gains.

 

Yeah I have been looking into getting some longtubes, I am just worried about how long my bottom end will hold together. So you dont think I should mess with the internals as of now?

 

Ok yeah I think the pistons are 4.0 Im not positive...

 

Restrictive exhaust is bad for the motor. The higher you spin it, the more backpressure you are building. If you can afford to do internals also, then do both but the internals alone wont make it any faster.

 

Yeah your right... and definitely dont have the money full time college student working 3 jobs trying to just make it!

 

Fake it till you make it.

My best friend lived very comfortably on student loans for his 5 yr stay at U of F. Ofcourse now he pays $650 a month for the rest of his life.

 

I know thats right... In your opinion, best headers for the price?

 

American Racing makes the nicest stuff that I have seen lately but they come at a premium. Kooks is a close second and so are their prices. I think that Texas Speed has a very nice 1 7/8 at a real bargain. I could have them mixed up with another of the big vendors on here though. I want to say that they were under $500 compared to the $800+ price tag on the Kooks and ARH pieces.

 

ya but u could also use more boost if u build the motor anyway

 

He'll probably lose some boost when he opens up the exhaust but it will go faster.

 

Yeah I saw texas speed had a set for bout $500 that look really good, just got to find a y-pipe and cut-out and I will be set.

 

Before you go spending all that money on new stuff consider the for sale section on here there's always cherry parts for a fraction of the cost of new...

But that's just me I'm a bargain hunter lol

I'd also say find you a nice set of tsp true duals IMO you can't find anything that sounds better!


Good luck man!
