I vote for Hypergear Turbos, have used 3 of them myself. Tao @hypergear is quite active on these forums.

I would suggest getting the ball bearing option, day & night difference from the journal bearing.

Be aware that a Hypergear turbo is not really a direct replacement from an engine management point of view. They make more boost and flow than the R33 ECU will be happy with. Talk to Tao about your options to keep the new turbo not so far away from the capabilities of the stock turbo so the ECU doesn't shit itself.

Then just get a @Toshi remapped R33 ECU (yes it is possible, only very select people can do it) for 1bar boost, FMIC, stock injectors, stock MAF, better fuel pump etc.

Should give you about 190~210kW at the rears.

I have gotten contact with one who has a original Turbo, the rest of the engine is not original though. I have an Apexi ECU, biggee injectors and some stuff inside the engine.

Should have said so before. All our warnings and information about not going too big on the turbo can be ignored. A bigger turbo would be fine. Probably better to spend a bit more on something new rather than a stock ceramic time bomb.

Yeah but the thing is the car inspection does not like bigger turbo, i have an Garrett 34xx already but i want it to "look" original so it can pass inspection. So as soon as it has passed inspection i can swap back go the better turbo. 

 

So i wont boost it more than 0.8 and map it to as close to original as possible then have a map with the better stuff.

    • I also think it would be wrong to say that RB's are weak or inherently flawed. Their oil control issues and block strength aren't a design flaw, they did exactly what they were designed to do when being used for what they were designed to do. Really it's the fact that they are quite a solid base that we are discovering their limits, because people are trying to push them to 600-700-800+ horsepower. Go and try that with a Toyota 2ZZ, the crank starts walking around at 500hp and you can't stop it. There's plenty of motors that legitimately can't handle it at all, the RBs sort of can but you're asking a lot of them.   At the end of the day, there's just no guarantees either way. You might build a 600hp engine and have it last 15 years, it might last 2 months - there's no way to guarantee it. So you're playing an odds game, you're rolling the dice. And if you aren't comfortable rolling the dice with the amount of money that it costs to play the game, then the best advice anyone can give is to not do it. Don't go to the casino and put all your money on Red if it will hurt too much when you land on Black.   Just ask Laine@bcozican, he's the sort of man that stands with his back to the table and barely even checks what colour the last throw landed on before rolling again 🤣🤣🤣❤
