I'm, planning on putting a 42/48 garret turbo with internal wastegate on a D16Z6. I have a vx manifold just using space in the garage, so I was thinking about using it. I do, however, have access to a TIG welder at school, so I've been thinking about making my own log mani, its just that I haven't tried a TIG welder before, so I'm a little concerned about the result

Whats the difference in performance and innstallation? I've read that with a hf mani, the turbo will hang a little low, so the oil drain will be difficult? How about PS (I have no AC)?

Any thoughts?
Thanks

id go with the hf mani, i am going with it on my z6, just gasket match and port thr runners, by the way, anyone no where i can pick up some polish for porting and polishing? and i think the hf mani flows better then a log anyways

it does.

Does anyone actually have proof of an hf style manifold out flowing a log manifold

hotrex

ive never seen solid proof

interesting, i switched from a PORTED hf manifold to a log manifold and made 43whp differance. same exact psi. no other changes.

thats pretty crazy. maybe the hf was leaking.. either way, thats cool that you made 43 free ponies just like that.

I can't imagine him being serious. I've seen a log make 270 and a ramhorn then do 300. And I think a log would flow better than an HF, but no proof.

I would also think a log would flow better than an hf, have you seen the ports?

Not to high jack or anything but is it true that the top mount generates more power than a ramhorn?
