if you use the vtec killers, look in to the ferrea setup.

 

From personal experience. Stay away from plm. I know the header is popular here but the quality control is horrible.

 

I'm running the PLM manifold. It makes good power on my open frame T66 HO (466/300 on 93) but I would buy something else. The lower gate flange cracked off in under 100 miles. Thankfully I had a spare flange and a good friend who is a fabricator. I had to hand port and gasket match the manifold as well. I would buy a Sheepy manifold, full blown or full race. Don't waste your time with the PLM unless you are prepared to make it work.

Ill look into that but would that turbo have potential for more power?

Scorpiant:
I want to have potential for more power just in case i decide that its not enough. I really like all the divided t4s but for the price i may as well get one custom made.

What do you mean specifically?just springs and retainers? I plan on doing that anyways. Unfortunately even with all those upgraded,i wont be able to rev past 9k with my f22

thanks sylvain2000 and liljoe, i almost pulled the trigger on the plm manifold few months back. Glad i waited!

 

have to agree with what others have said, stay away from plm, I have that manifold on my car and I've had to fix it twice. they advertise that their manifolds are sch 40 but mine is sch 10 if not less.

when it broke it was the lower wastegate flange for me as well
