Time to replace my turbo? GT3071R

Hi Guys, so I'm pretty sure the oil seals in my GT3071R .82 are gone, it is now blowing oil, a small amount, into my intake and when on a hill leaning down it leaks oil into the exhaust making quite a smoke show, not cool.

I have always been happy with this turbo, been on the car for around 6 years trouble free. I got a quote for $500 + parts for a rebuild but at $1300, I tink I would be better off buying a new upgraded GTX model to replace it, hey have a billet wheel and are said to be even quicker spool.

Question:

- Should I try to rebuild it myself?
- Get the GTX? Anyone running one?
- Get something else?

Only runs 7psi and don't really want to run any more boost right now as it doesn't have a tail or an intercooler.

Cheers!

That's a small turbo. Even smaller than mine. What's the response like? You're only running 7 psi because you have high compression I assume? I bet you have almost no lag!
If I were you I'd get the gtx

I read they are not rebuildable by a DIY'er?

Hey mate! The response is great, engine is 9:1 not the high compression 3.2 if that's what you mean, I can run 10psi with an intercooler but don't want to mount the tail. Read lots of how-tos on the rebuild but don't really have the time and patience right now. Think I'll try out the GTX, maybe a GTX35, probably too much turbo for my application though.

Thanks for the replies guys!

The GTX3071R flows the same as a GT3076R, but it still has a smaller 71mm compressor wheel. It will easily support 450 HP. Just installed one on my 3.0 liter Turbo. As soon as I get my new WBO sensor controller wired in, I will find out how responsive it is.

Hey Paul! I haven't been back for a long time but will be there most of September, mainly LA but if I go north I'll make my way over. Please tell me the flat nose is running?!

Interested to hear mate!

Yes, if you get out this way be sure to holler. And yes, the flat nose still sitting, lots of progress but not enough time. I've done a couple other builds that kept me busy and pushed back the time for this one. Hopefully this year. Hey.. I said that last year didn't I?
