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.

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
