Another Dead GReddy Turbo
And my turbo gave out, car wouldnt go into boost....
The white smoke is nuts.. similar to mad dog's case:
https://www.rx8club.com/series-i-major-horsepower-upgrades-93/got-greddy-turbo-you-need-oil-line-restrictor-93772/
The irony is that my oil restrictor and interceptor is arriving in the next few days....
So these days i've been reading threads about efficiency of the T618Z....
Should i be considering another turbo or just get it rebuilt.....?
What turbos would you guys recommend that is an almost straight swap. Will the T518Z 8cm suffice? I think that's the only turbo my local Trust guy has in stock. Take in mind, we dont see Garret Turbos here...
Mazdamaniac once mentioned about a water-cooled ball bearing turbo.... Any elaboration would be great...

How much would rebuilding a turbo cost?
I live in southeast asia so choices of new turbos are HKS and GReddy for me...
Somewhere around 9,000 miles...
Would a T4 fit in the spot where it initially was? Any idea on approximate costs?

There's virtually no info available on the Bullseye upgrade. They have no dyno charts, no hp claims, no flow charts. There is only one member who actually tried it and his experience was not very good as it didn't fit very well. Although they may have fixed the problems by now. I think he was fairly happy with it once he got all the issues sorted out. However, it still retains the Greddy hot side, which I believe is the reason for the boost falling off. So you take your chances with it, although it is cheaper.

Ex- member.
Mazsports will be much better.
Bullseyepower only swaps the "upgraded center section and compressor side while using the originial turbine housing that GReddy provided.

Sry to hear about it man. Mine is still in the shop and my tuner told me another 8 with a popped motor recently arrived as well. Apparently he had a very similar setup as me, gredy kit and the interceptor, but thas about all the details I heard.

Would an HKS GT2835 Ball Bearing work? Rated up to 380ps.
Measurements are
Inner dai 49.3mm
Outer Dia 71.1mm
A/R is 0.64
With Internal WG
Price quoted to me is quite good... So its in my considerations.. Unfortuantely i dont have an engine flow for the renensis so I am not sure how to compare it to compressor flow... Can someone give me their opinion?
Ps would i still need a restrictor if i run this compressor? Its a ball bearing type

It's sad to hear that this is happening with those Greddy turbos, I can't believe it. In all these years of me being in the rotary game the Greddy turbos have been probably the most reliable turbos for rx7s from what I've seen, I'm surprised that these small turbos aren't lasting on the RX8s, UNLESS it's due to people not running air filters with them, if that isn't the case then the only other thing I think it could be is that the turbos since they're so small aren't able to take the heat from the rotary engine and/or people aren't letting them cool down properly.

^^ Did you even read any other parts of this thread?
The turbo dies from too much oil pressure.
What is really bothersome is that GReddy hasn't addressed this basic principle.
Benny is going to be so sick of my face at SEMA this year...
The question isn't just "what will fit" as a replacement but "what will have to be fabricated to make it fit".
I could fit just about anything down there if you give ma a few days with an angle grinder and my MIG welder.
What will bolt on? Probably very little.
I'm liking the idea of a Garett GT-series. It will require hacking up the manifold, but that is no problem for even an average fabrcator. I could probably do the whole conversion in one afternoon (including the addition of a cooling line).

It's interesting that there was no restrictor in the oil supply to the turbo on the TIIs.The turbo sat higher relative to the oil pan,the oil outlet pipe was bigger size and returned the oil into the front engine cover.It was easy to get 100kmiles out of the turbo.
