However if you are looking to reroute your wastegates, without a DOUBT choose an IWG EFR, Especially on a dual wastegate setup.
Very nice mani / dump pipe setup.. just a sidenote the 2nd wastegate will disturb exhaust flow beeing plubmed back in at an 90 degree angle of the DP first one is gine though..

I agree 100%, if one is going with an EFR.

to get some more examples up, here's my plumbed back setup on a RHD FD with a BW S300..i do wish I could afford an EFR, lol.

Just in reference to the wastegate overheating thing again. Was just under the car now doing something else and wondering how the hell i was going to duct around moving steering arms and ****. I'm almost certain now my problem only happened on the dyno. now that i think about it, after the 1st dyno session early last year, the black anodised progate40 turned brown, stayed like that until the next dyno session where it went Gold and the diaphragm finally ruptured, and i put a new wastegate in.
Halfway through resuming the next dyno session i turn up at the shop and arranged to have a fan blowing air under the hot-side.

Upon inspection, the black anodising on the offending WG is just starting to brown, but has stayed that way after a couple 100km's of driving.

My Hypothesis - blow air on them at the dyno. Other than that they should be fine. And the anodising on the top hat seems to be a good indicator.

Choosing Wastegate/s

So much knowledge and soaking it all in! Lovely setups. Thank you all for contributing!

I got my turbo back today from getting it some fancy coatings. 2000 degree ceramic coating on the hot side and powdercoated on the cold side.
