97 to 00 had the ls1 intake

01 and 02 had the LS6 intake

Ls6 outflows the Ls2

Ls2 is similar to the ls1 intake even tho it has a 90mm opening and on paper it looks to be better then the Ls6 it actually isnt

IMHO there are only 2 intakes out there worth any money or time installing....these are the Ls6 and the Fast90 [ported 90 is tits]

I run the Ls2 cause im boosted and wanted the bling factor of reusing my 90mm tb and allowng myself to use 4" tubing. If i was building a turbo Fbody i would just use the LS6 intake


Now for what you want Jeff, if you cant afford the Fast 90 then Port your 78mm tb then run the Ls6 intake

to run the car intake you just need to take the idler pulley from on the Alt bracket and side it over about 3" to the other bolt that is there now. this will allow you to run the car intake with still using the truck accesories.
