I've got an 89 IROC and here's how the buildup is going to be:
L98 with alum 113 heads
large tube runners
lt4 hot cam
1.6 rockers
hooker shortie headers w/y pipe
t5 5 speed (until i can get a t56)
3.73 posi.
was wondering what everyone thinks about this setup? any suggestions also.
how much power do you think this would give me?

 

I don't think the t5 will hold up to your setup.

 

Sounds exactly like my previous setup, except I had SLP 1 3/4" headers instead of 1 5/8". Dont forget the custom chip tuning, and your T5 will be fine as long as you dont race it. Mine blew up once I started running 12's on ET Streets.

 

I would skip the shorties and get long tubes they may not make a huge difference now but they will if you keep upgrading like most of us do,oh and get them coated not painted black

 

I've already got the coated shortie headers, so i'll go with them right now along with the t5. Those changes will come later. Where's the best chip tuning if i don't want to do it myself? thanks
