correct alex hence it should be good buying for anyone interested in upgrading their turbo.

i bought it to use on this car but GCG suggested their R33 hiflow turbo would not be the best choice on a neo RB25 so it is sitting there looking for a good home (it has been sent back to GCG to be checked before sale).

btw i have an R33 GCG hi-flow with less than 5000k on it if someone is looking to upgrade their turbo.

how much are you looking for it? i was going to upgrade mine in the next few weeks during my manual conversion

LOL, why did they say it isnt a good choice??

R33/R34 turbos are interchangeable and the highflow of both turbos is identical (AFAIK), apart from the R34 turbo having a slighly larger (debatable) rear housing.

Its not the turbo that will be your limit anyway (maybe 230awkw vs 240awkw R33 vs R34), its the way you tune the car. I think it wont be easy to max out the turbo with piggy backs....

alex the rear housing is different on an R33 vs R34, it is not questionable. the outright power goal was not the issue it was whether the smaller turbine housing could be an issue on a neo RB25. in life you sometimes have to take the advice of professionals that work in that field. i am not a turbo expert but i have seen enough threads by disappointed punters that mismatched turbine housings to their application and have spent $$$$'s chasing their tails trying to fix it.

who said anything about piggybacks??

terminal pm sent.

sure is alex

the powerFC (all things going well) will be fitted in the next few weeks and then we can see what the drivability is like down low. the midrange and top end won't be an issue.

the R33 hi-flow would make plenty of power for my application so an extra 15kw or thereabouts is neither here nor there to me but for the reasons above i will use a hiflowed R34 turbo to avoid any potential issues. i am trying to re-coup my costs on the R33 turbo.

the guys at plazmaman installed it and they used this as a test mule for a kit they will offer.

the price i paid may not relate to the retail cost for the kit since i was the first one.

i have a plazmaman FMIC on my R33 and i found the service and "care factor" very high with plazmaman after i ran into some difficulties installing the kit (not due to any fault of the kit). the patience of oyay & alex and their desire to ensure i was completely happy should be used as a model by every other workshop.

in addition, i asked them to look at making a replacement pipe from the afm to the turbo although if looks to be a complex pipe that might have too high a cost to go into any production unless there is enough demand from skyline/stagea owners.

i imagine the kit is available if anyone is looking for an alternative to the other kits on the market.

    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
    • Welcome mate. Any pics? Even with a DE I'd be well happy if I had that as a 1st car.
