TURBO??? how big is to big

first i want to introduce my self.... my name it thomas manghelli and i live in mississippi...


well i have a 6.0 iron block out of a truck and i also have ls2 ported heads...i also have the wiring harness and computer along with a built 4l60e...

i am wanting to put all of this in a 98+ s10 or possibly a 99+ full size(WHAT I REALLY WANT) and keep full street ability a/c and what not.. but the thing is i want to TURBO it also!!!

how hard will this be (ether way it will be done..lol) and what size turbo should i go with... i had a precision 76mm on my lightning (that just burned to the ground in a shop fire) and it was awsome it made 720rwhp@20psi on pump gas... i am wanting something like that again(OR MORE REALLY) just no where near the money i had invested in my lightning....
i would like to eventually run low low 10's high 9's... what turbo set up would alow me to do this?

i'm new at the chevy stuff so any help would be very greatly appriciated


how much does a RCSB full size wiegh with a 6.0l in stock form and how light can you get one and still be very streetable???

This might help.

With the 6.0 and the ls2 heads you should be fine with another 76mm. I think the 88 would be the biggest though.

Are you looking for quick spooling or max power? For quick spooling I'd go with a 70mm, max power 80mm or up, good compromise would probably be a 76mm.

FYI, 6.0 iron block and 243 heads is going to have a pretty high compression ratio with stock pistons, which will limit your boost potential. I'd think about swapping back to a set of 317 heads if I were you.

i'm gonna build the motor so i can change the compression

i am looking for power i'll put the stall convertor in to help with the spool

ok so my deal fell through

now i am gonna try to find and piece together a 6.0l with the 317 heads(stock 6.0l correct)

did you have pictures of your lightning burnt up on svtperformance.com? that was a rough one if thats you. and i hope this all goes well for you.

PT88 with some love juice to help spool it! but then again i'm biased as i'm working on a 6.0 block and plan to use every bit of the PT88 i can
