Just got a GT28R. What holes are for what? Water and oil. There is a 2-bolt hole with a gasket and 3 other female threaded. Help your knowledge impaired fellow member.

Thanks for educating the simple minded!

One more quick question. Is any shaft play end to end or side to side acceptable in a GT series turbo?

Side to side, less than 1mm is ok. In and out, as little as possible.

I always thought that the ball bearing turbo's would be a little tighter than a journal bearing. Am I wrong?

Which holes are in and out is easy. What goes in and what goes out is hard. According to Southpark though the flow is reversible.

My problem now is trying to clock this thing. Frozen like a mf. Been hitting it with wd40 for a couple days now. Tried torching the housing and whacking it with a deadblow, it isn't budging. Doesn't look that rusty either. Damn.

Gave up on the torch and rubber mallet. Went with torch and real hammer. Scary but popped off. Finally got it.
