View Full Version : Wastegate actuator fouling on block

24-06-2016, 09:54 PM
As the title states, currently have a t28 off a rwd sr20 just wandering what you guys did in regards to the actuator and also bracket. Im running a gtir manifold and the turbo is currently clocked and everything fits fine apart from the wastegate actuator fouling on the block. Any pics and links would be greatly appreciated.

I had a lot of trouble with this too. I ended up buying a generic wastegate mounting plate off eBay and modifying it the best i could to fit.

are you running a manifold spacer? because that what everyone has to do with 2871's

the wastegate was getting crushed a tiny bit with the GTX28 and a 10mm spacer, so grounded down the sharp edges on the block and filed out the wastegate mounting bracket. the amount of damage pictured wouldnt have any affect on the spring though, not deep enough.

Im not running a spacer. I have a t28bb off an s15.
My block has been shaved a little bit, if my memory is correct.

Yer not running a spacer, are you?

The wastegate actuator doesnt fit any more now that the turbo has been rotated, looks like ill need to buy a custom bracket with elongated holes or modify mine and buy a longer rod.
