If you are tring to get 500 HP without nitrous or forced induction you will want a FAST 90 with a Nick Williams 90MM throttle body. You will also need great heads with a strong valvetrain, big *** cam, and probably just about every bolton.

500 fwhp or 500 rwhp? There's a big difference between the two...

For 500 fwhp that's around 425 rwhp, ls6 intake should work fine.

For 500 rwhp you are getting up there, you could easily use a ls6 intake, and it would work great, but it would make much more power at that power level with a FAST 90/90.

For 500rwhp I would go with a Fast 90 intake and a NW throttle body. This is also assuming you are talking about being NA and not FI.

I was hoping for 500 rwhp someday. I just wanted to start planning on the right parts so they will all come together down the road later on. Yeah see thats what i'm trying to find out, at what point is it worth switching to a 90/90. So far everyone is saying if i stay n/a i should get a 90/90? so what if i wanna end up doing a s/c or no2?

lol, everytime i think i'm onto something with planning theres always more to these parts lol

If you are seriously planning on getting 500 rwhp, go ported FAST 90/90 right away. It's not going to hurt you if you are making less power, compared to the ls6 intake on. But might as well only buy an intake once, if you see your self going there.

You will gain power, any potential power loss would occur low in the RPM's and would be small, but the gain up top would well outweigh the small loss.

No I'm saying you will NOT lose power, so except for cost there is no disadvantage to putting it on.

Its a good thing to go with no matter what, but that intake is expensive.
