108354, Hahn manifold (internal gate) to externally gated manifold
Posted by Red90Sev, Dec-14-10 12:31 PM
So, I wanted to go with an external wga setup, but have a Hahn manifold, has anyone put an external setup with a Hahn manifold? I don't really see an easy way to do it other than to just buy a manifold with an external flange. The only problem with that is, if I go with a different manifold, the downpipe and intercooler piping will no longer line up. Anyone tackle this problem or have any good advice? I'm kind of just weighing my options, I live in a small town and don't really have access to someone for welding anything for very cheap.

just curious as to why?

If ur gonna modify hahn's materials, you'd have to find someone who can do a really good job. internal gates work just fine. I'd leave it if i were u.

I agree with Mikey. Just order one of Hahns modular internal wastegate actuators. That way you have the ability to change the spring rate.

Thanks for the input guys, I wasn't really considering modifying the Hahn manifold, was leaning more toward a Star types manifold. I think I will give Hahn a call though and get a different Internal WGA.

yes. if you already have hahn pipes and a mostly hahn setup, getting another hahn WGA would be a smarter route. Cheaper, less work, time, and effort. good choice.
