Here's something id love to see done, hell, id love to do it myself had i have the cash.
Anywho, Theres an ebay turbo kit for the LS1, meant for 98-02 f-bodies but ive been studying it the last while and im 99% sure most of it will fit into our cars. A tubular k-member and i know it would.
Here's a shot of the kit:
Its just the hot parts, but the headers will fit, and so will everything else down to where the B&S Flange is just prior to it splitting into 2 pipes. It may need a little tweaking but its $590 for the whole setup and its all made from stainless. Theres a few guys on LS1tech running it.
Search "LS1 Turbo" On ebay and you can find it.
Do it, and tell me how it works
