A 67mm turbo on a 4 cyl and one on a V8 is totally different.

Yeah a 402 might put out a bit more exhaust flow then a 4 cyl...

If you move a maxed out turbo from a small displacement motor to a large displacement motor, it will not make more OR the same power. It will either make ALOT less or not even work properly at all.

I just want to know which turbo to bolt to my STS kit. I am in the early stages here but I plan to be complete with the setup I want by then end of 2007. I am open to suggestions but kinda have my heart set on the 402. plus I can then sell off all my stock stuff to buffer the cost as well. so what I need to know is what turbo would be ideal for this application 402ci ~9.0 or 9.5-1 C/R and advice on a set of 6.0L heads.

Also as far as a fuel system I was planning on sticking with my walbro 255 a boost referenced regulator and 60lb injectors or should I go bigger on the injectors ??

will my LS6 intake work ?? if so how well ?? I was also looking at this intercooler any thoughts on this intercooler http://cgi.ebay.com/ebaymotors/FMIC-...mZ230037473653

Your fuel pump might not cut it. Double it.

The LS6 intake has reliably pushed cars into the 1k crank hp numbers.

Why not go lower on the CR? Is the motor already set-up at 9.0?
