Rebuilding R34 Gtr Turbos With Steel Wheels

[hypergear]

mmm the GTRs turbine would work with a .49 rear fine. Even now Garrett still use them as upgrades on the 300zx and GTR OEM turbos. Putting a big comp wheel in to small housing will cause surge. But this wheel is not big enough to do that. It will still make reasonable power, in any twin turbo setup you can't have 100% efficiency out of a single turbo out of any housings you put in.

any way, we can supply Garrett GTRS-5 for OEM GTR upgrade at $1250 each. So might want to pay abit more and get that with brand new housings and actuators instead. Depends on your buggdet

Hey mate,

I got mine rebuilt with steel wheels using the existing housing, it cost me around $1200 for the two of them much cheaper than buying -5 or -7. It really depends on what you wanna do with the car, I got 254awkw on 18psi before the clutch started slipping, still a good result with a bit more boost would have been close to 300rwkw. At this level and also very close to mine you need new clutch new afm and new injectors, cost you anround the 2k for the clutch, 600 for afm, 600+ for the injectors and will be out of puff on the fuel pump. in the end I decided once you go above the limit of the std equipment it starts tocost you $$$$. I was content with running close to the limit of my equipment so rebuilding the std items with an upgraded spec was a better option if you dont want to chase big power. If done properly the responce should be better than stock. Its not a job you wanna do a couple of times as its costly if you dont do it yourself. Will send you the guy who did mine if you wanna know.

Also very happy with mine. Yours are gonna have slightly diff comp wheels and housing on the front as well.

Have Fun

They were $1200 because they were not a ball bearing center, like the Garretts.
