would there be any advantage of having a manifold with an external wg along with an internally gated turbo? call me stupid for contemplating two wastegates but i do not want to change manifolds when upgrading from internally gated t3 to t3/t4.

 

yeah youll just have to block of it External WG hole on the manifold

 

I'd use the external wastegate.. its alot easier to use and less problems. just use a 5 bolt downpipe flange that covers the internal gate hole.

 

What he said. No reason to leave that shitty internal on there. Once you go external, you never go back....unless you're in a $ pinch.

 

call me lucky but i've never had a problem with a internal ever but then i've never used a external brobally never will love the internals to much

 

Maybe I just had bad luck with the internal, but it seemed like colder weather = more boost Also I'd consistently get ~2+ psi if I made boost build quicky, then it'd fall off to it's set amount.

I've used externals on 2 setups and never had any of those problems. Plus it sounds meaner :P
