I was going to say the 900 also. The 770 would probably do it, especially seeing as you're proposing to use the same exhaust housing whichever way you go. But the 900 should still rip on a 3L bottom end. But, A word of caution. Will you be able to fit that turbo on the low mount HKS manifold? There's not a lot of room down there for a biggun. Is the top mount wastegate offtake common to both halves of the manifold? If so, then that's a bit shit. Kinda ruins the point.

Ethanol or 98?

Dunno on a 33. The core is buried under the dash on any car and is no fun to get to. The TX valve could be also, or could be on/near the firewall behind the turbos. It's a job for a fridgy anyway.

I'm as close to normal as any of us and I daily a bloody R32 that is appreciating into the stratosphere and rapidly becoming irreplaceable. /TotallyNormal!

Just do a long smoky burnout on the street. Cheaper and easier than breaking it at track and just as good for testing the idler and the gearbox. Bonus, if you get it confiscated, then you can stop bitching about it.

Ignore. Typed a fluffy answer.

If it's freezing the evap core over, then it's not a leak/gassing problem, or a compressor problem. It would be a TX valve problem, not cycling the compressor off when the core gets cold enough. So either the TX valve stuck or the temp sensor come off the core.

There is no difference between an RB25 and an RB20 exhaust for the same car. It's the same engine, near as dammit.

Is it on auto?

I have quoted myself. It is not plug and play. You will have to integrate the looms. Different cars, different wires doing different things. All in the engine bay.

Well, that's hard to believe. How do all the GTRs run aftermarket ECUs against the (basically) same ATTESA CU?

No. The clutch is different on the NEO DET. It's a pull clutch, whereas everything else (except R33/4 GTRs) is push. Your existing box and the 33 turbo box should both be push. But it's not as if it matters. Just use a clutch to suit whatever box you end up using.

It's no cost at all for a workshop to buy a scantool that will confidently work with almost anything.

Not only would you not have to Nistune the ECU, but you actually cannot. The R33 ECU is different to all the others and won't take a daughterboard. The R33 does not have TCS and so doesn't care if transplanted into a chassis without it. The R34 ECU expects TCS. There is one option there though, which is to get a Neo from a Stagea, as they did not have TCS either. But, I would be at least Nistuning the ECU so you can tune the bloody thing anyway, so a Stagea motor is not really a solution to a problem that needs solving by any other means than Nistuning anyway. I'm not sure what you're asking here. Are you asking if you can transplant the exact same engine that you already have? The R34 GT has an RB25DE Neo already. There is no particular reason for your existing engine to "blow". They are tough and understressed.

I have communicated with all of the (steadily decreasing number) of CUs in my R32, using a Snap-On scan tool. Snap-On are just implementing the Consult protocol.

No. You will have NO option but to Nistune the ECU or use an aftermarket ECu to run the Neo because it will have a shit fit over the absence of the TCS CU.

Yes. Yes, it will mate. But, this is not a trivial swap. You will need to sort out ECU and engine wiring, as they are not simply plug and play. You will need a fuel pump, stronger clutch, intercooler and plumbing. You really should upgrade the brakes. By the way - this question has been asked on here about 1000 times before.

CFD stands for Colourful Flashy Diagrams. Also Confusing Fcuking Dickheads.

I really love it when people create smoothly distributed pulse-free gas inlets and outlets with no upstream or downstream geometry, no pressure fluctuations (which are actually waaaaay more than just fluctuations in a turbo manifold) on things like manifolds, then present a steady state solution instead of a transient solution. It's so sad. And, to use the CFD that's built into Solidworks and present that as if it is any bloody good at all it even sadder.

Ceramic coating the piston crowns would have to be about 3x as easy to achieve and 3x as effective, no?

Same same

My takeaway from the last 2 videos is that you should sleeve an RB block before it splits the bore!

Le sigh. For what car? A 2011 Mini Clubman?

Not going to speak authoritatively on the GTR tank.....but almost all plastic tanks are HDPE.

What sort of speed sensor was used in the C34 auto? An electronic sender like in the typical RB25DETmanua l box? Because, if so, you are shit out of luck. The RB20DET speedo is usually by cable drive. I don't know of any electronic drives for that gearbox. There are for the related 4 cylinder gearboxes in Silvias etc, but I don't know if they are useful. So, where is this odd "half" speed signal coming from? If you can identify if it's coming from a diff sensor or ABS sensor (ie, that's the original way it was on the C34) then you might be able to just use a speedo adapter box like you can get from Jaycar and various auto-electrical crowds.
