What is the best option for a intake manifold for a turbo application? Cathedral port heads and something other then stock.

 

Vic Jr. Just do it.

 

And an elbow?
What elbow do you use?

 

Thought u had a fast already tho?

 

I do but not for sure I'm going to run it.

 

i plan on running the holley hi ram on my ls3 headed ls2

 

+! i wanna know the same. which one is gonna get the most performance out of it? i've seen the turbo'd trailblazer get a LSXRT in the gm high tech article but never really seen any personal experiences. with this intake.

 

If I had a fast I would probably run it. I cant see switching from it making substantial gains over another aftermarket intake. IMO

 

I think it's Nelson that's really pushing the Holley Hi-Ram's. Supposedly, they work really well with turbo applications. If I went the turbo route, that's probably what I'd use. I don't know what usable rpm range you're shooting for or how you plan on setting everything up, but the Vic Jr. w/ elbow wouldn't be my first choice, due to the high rpm's it'd like. Z71 knows what he's talking about, but I don't know that I wouldn't try for the Holley Hi-Ram or atleast use the FAST first to see if I liked it.

 

Personally I run the Holley intake over the fast, It looks like it will flow great for turbo application but too bad they didnt offer them for Ls7. I heard on other forum that ls7 intake are ready and will be out soon.
