I've always thought the 300ZX single turbos came with a T3 that was around .60AR on both intake and exhaust side.

This guy has one that does say .48 on the hot side - though he's unsure what the specs are for the compressor.

Anyone know what compressor specs are for this type of 300zx turbocharger?

And what years and trim levels came with what turbocharger?

TIA

Randy

i know some of the 300's came with a .63 exhaust housing and an exhaust wheel which is equivilant to a stage 2 wheel (according to alamo), but the .63 housing has an odd bolt pattern for the swingvalve.

Well, it's back up again for auction. kinda interested in this one...
Can anyone speculate what JDM engine this came from? Guess the best person to ask is the seller.

That looks like one of the twin turbo's off of a z32 or something, doesn't look like a z31 one.

The Z31's have a bolt-on 90 degree outlet, and look fairly close to an RB20DET turbo. That one looks different..

I specualated that too.
But didn't they come with T25's?

This one is seems like a T3 flange. or is it?

So here's another one.

Some say it's RB20. Some say it's RB25.

Is this the Ceramic BB turbo? doubtful, and not necessarily great if it is - isn't longevity and durability compromised in that kind of turbo?
