Recently purchased a T28 from Louis, he sent the EX housing to extrude hone per my request. Here are a few pics. I thought a few people ahd asked about this so Ifigured I'd share them.

Before

After

You can see the bumps in the housing are significantly reduced. You can't even see the .86 on the inside of the extrude honed
housing. Looks good, not bad for $75 plus shipping.

as far as improvements it has yet to be tested. Project 1.6 is running a straight T28 and with the pulse converter manifold it is spooling up rather quickly. I'd say maybe a few hundred RPM's but that is just a guess based on previous people's experience with this. Time will ultimately tell!

You know the GTi-R T-28 turbine housing and exhaust elbow is the only AWD SR20DET I have seen with those exagerated humps. Well atleast I know my W10 SR20DET does not have those humps in the turbine housing and very little in the exhaust elbow but not as much as the GTi-R. I wounder why maybe it was to limit horsepower on the GTi-R or something?
