If price is an issue, just get a Weiand or BBK. Next on my list would be a FAST. There's a lot of people still using LS6 intakes though. Even with that much boost

If your going to stay with a stock style intake the FAST intake is a big waste of $$

Just like Todd said... stick with the LS6.

How do you like the LS2 on a boosted application. I know N/A they suck but for F/I I think they will work great. I have and going to use it if I use a LSX engine. The other alternative is the new L92.

Yes, the LS2 intake works very well for FI. It's been to 17lbs for testing purposes.

LS6 for me right now, 18-21psi. Going to Edelbrock single plane soon. I would probably avoid the FAST 90 for big boost, given that it's a multi-part intake.

true true, so a ls6/ls2 intake seems the route for me to go down, avoid aluminum due to potential for heat soak, correct?

I will be running an LS6 intake on my setup. 94mm turbo and we plan on pushing at least 25+ PSI. The motor will be a 370 ci iron motor.

Cartek has their TT Z06 running twin 67's with the LS6 intake. 22-24 PSI without a glitch!
