Turbo upgrade on ebay for EA82, no joke.

Featured Replies

I don't see anything that says it's for an EA82T.

Says he bought it for his WRX, which would mean 2.5 litre. Then bought the STI. Someone has too much cash.

Bradd, I thought the WRX was a turbocharged 2.0? But you are right, too much money on his hands...

The RHB5 is the VF7 or whatever that came on the Legacy Sport Sedan/Wagon (turbo legacy).

I can't see the serials on it, or I would tell you for sure. If you want a serious upgrade for your EA82 though, lemme tell you the secret.

 

Take your old RHB5 off, remove in the intake side of the turbo, exposing the compressor. Now remove the compressor. Find yourself an RHB5-2 off a turbo Legacy, early 90's type. Now take off the intake side of the Leg's turbo, both the houseing and compressor, now bolt the Leg's compressor onto the 82's turbo, then put on the Leg's housing, wha Lah, you have have a turbo that puts more boost, but doesn't spool any slower. Now all you have to do is bypass that boost cut problem.

Its an RHB5 that came on our EA82Ts. AND, you can tell by the exhaust housing and by the overall structure of the turbo that it will bolt right up to and EA82T, IF the housings were turned right.

well, I dont know the exact procedure, but.. its a good idea to balance it because they do spin at 120,000 rpms + even if its just a little off, at that speed.. it could be a problem..

im sure you could get away with not doing it, but that would imact the life of your turbo's bearings..

cool . if that turbo was designed for a wrx then the exhaust side flange is slightly different than a ea82 turbo ( I tried it once). I have considered doing a wrx turbo swap. but it requires a good deal of fabrication and I need more time/money:-\

 

adam have you done the legacy turbo hybrid? sounds really cool. I want to know more. sounds easy enough to do.

No, its NOT a TD04, its an RHB5 with a different compressor housing on it. The exhaust housing is IDENTICLE to ANY RHB5 on ANY EA82T, that I am sure of. But still both housings are bolted on all wrong.

so - what you are saying is, the exhaust flange on the legacy turbo is the same as the ea82t, but the it points all the wrong way? .. cant you rotate the compressor housing?

or is the turbo setup to sit the wrong way...

the Legacy turbo is a VF10. The RHB5 i think is a VF7.

 

The US WRX is a mitsu TD04, and STi's and others get VF34, and 22's.

 

The exhaust housing on the VF10 is different than our RHB5's. The exh. housing on that turbo is origonal from the RHB5, it sjust turned the wrong way. I looks like its got a different compressor housing, and it too is turned the wrong way.
