It would have to be an intake from an 01or 02 Camaro or firebird.

 

01/02 fbody, or a Z06 obviously.

and you DO need other parts. you need to block off the EGR, and also buy the coolant bleed tube and plug

other than that it is straight forward swap.

 

When it comes to the LSX, if you have big cubes and high flowing heads, it is heads and shoulders above everything else IMO. I have a high revving 12:1 382 LS1 with MTI Stage 2R heads with 2.055 and 1.60 valves and IMO the LSX was the only way to go. By the way they are Pre-bunged for Direct Port Nitrous, and they all have provisions for EGR if you choose to pop out the block off plate. As far as throttle body i believe a stock 78 will bolt up, I am running a MTI billet throttle body however, unfortunately this engine has yet to find it ways between the fenderwells of an F-body.

 

Z06 intake should be fine. LSX is way over priced and deosnt offer enough gains over the LS6 intake to justify its high price.
