ok....

i have been deciding what i wanted for my next car. this will not be my daily driver, but i will be street driven/and raced at the track and street.

i have decided that i want to go back to a third gen after owning a 92 rs, then selling it for a lt1 4th gen. i want to make some serious power and make kinda a sleeper ( i don't want it insanely loud and obnoxious)

i will put this in a 88+ iroc or z28.

enough bs, heres the plan/questions??

rebuilt l98 motor
* 355 cu in.
* fully forged bottom end

BBS Designs twin turbo kit

i want to pull hard to around 6000 maybe 6200??

so...

what manifold/EFI system should i use??

i was looking at keeping the stock tpi harness and slapping on a miniram or a lt1 intake. or should i go superram??

what heads should i be looking at? could i run just some ported vortecs? i don't know if heads differ from NA cars to/ turbo cars, as far as what flow numbers i want??

what are some cam specs that i should be looking for? i would like to run a 114 or a 116 LSA but what duration and what lift numbers should i be looking for to have me peak out at 6000??

i know these are alot of questions but i would appreciate all the help i can get! thanks a ton guys

later

I would say go with a StealthRam, and a custom cam. As for heads it is really about your budget. If I could have any head for that set up I would go with dart pro 1's or AFR heads. Too much duration in the cam and you will just be pushing the boost through the exhaust so do not go too big. 114 LSA should be perfect for turbos.

 

heres my cam card for my turbo build (355 ci)
and a pic of my turbos creating an insane sleeper effect (stock hood, stock tires...)
using stealthram (very boost friendly and cheap)

and the exhaust is not done yet, but even with dual open down pipes it is quieter than the 3" cat-back I had on there before.
