I all ready have one of those $100 torsen units from SLP and I called and got some axels for it from the junk yard.
I don't know if I should keep the 3.42 and there top end speed or fork over the $$$ and get some 3.73's and there low end acceleration. I'm not having the torsen put in untill I know what gears I want to use.
I am useing 2 audi VW 06A turbos there kinda small so they won't lag. The one I have is brand new now all I need is a second.
The car has is a 85' with a brand new 3.4L with a crane 270 cam and $40 kmotion springs with a 2.8 fuel injection system and 22lb.hr injectors, also a standard transmission (back home).
I have 2.8 heads 3.4 intake manifold and 2.8 pentum with TB, fuel rail and MAF; 1 of the 2 audi VW turbos and 2 saab intercoolers over here with me.
What do you think?

 

i think you should keep the 3.42s

 

I would stay with the 3.42s. How much hp is this car producing?

 

Do you know if our T5s have the same gearing between my 4th gen and your 3rd gen? Honestly I like how my car is I am not real sure I woudl have wnated to go for 3.73s in my car, seems to lose alot of huff in the top of 3rd gear as is, granted your turbos will help out since it will give you more topend on your motor so its hard to say. I can tell you though 1st gear is like nothing in my car with my 3.42s and 5-speed, seems like it woudl pretty steep with 3.73s in.

 

It should be makeing about 190hp with out the turbos.
With the TT's, intercoolers the ported and respringed heads, cam 1.6 rockers I wan to make about 260hp.

 

I say 3.42s, seems 3.73s are relatively popular with t56s in 4th gens, and since T5s have more hear then T56s, seems 3.42s would be fine.

jsut my thought... though the main reason I got my 3.42s is my rear end was trash and found a used WS6 one reall cheap.

 

you have low goals for such an involved project.

btw I run 3.73s and I love them.

 

The 260hp is my base line numbers.

 

how much power can a sock 98 camaro Y87 (3.42 posi) hold, LT1 nitrous to much for that axle?
