Least important information in the whole book. Least relevant to anything now, or when they were new. Because.....they never did those numbers anyway!

The first table in the engine section of the R32 GTR workshop manual says

Hot coils or igniter. Sus AFM or CAS, particularly in the loom connectors.

Here's an old thread from SAU on what looks to be about the same thing... https://www.sau.com.au/forums/topic/267335-what-turbo-is-this-i-have-pics/

Ah. I see your response. 280Z would indeed be "dirty old". But....it can't/won't fit both a 280 and a 300. The 280 was an L series straight six. Any turbo for those would be a single turbo, needing to be T3 sized. I guess TB03 is in that ballpark. The 300Z was a VG30 V6. The turbos were single, but obviously the mounting location would be quite different on a V6.

So, the 0.48 on the turbine housing is the A/R of that housing. Which is SMALL. The dimensions you've given are not super helpful. The exhaust inlet flange appears to show 55mm on your verniers. That's neither the expected 50mm of a T2 housing nor the expected 58mm of a T3. Can you measure the other dimension across it, and the bolt pattern? The exhaust housing is definitely Garrett, not Nissan. The dump pipe flange is for Garrett style dumps, not Nissan style. The compressor housing is Nissan. It may not actually belong to that turbo originally. It may be a Frankenstein, cobbled together. The measurement across the outside of the compressor inlet is not super helpful. The inner diameter is the useful one. We can see from the verniers that the ID will be only ~55mm and that it hasn't been machined out as part of any highflow work. The actual inducer all the way down at the compressor wheel would be another 10+ mm smaller than that. Sadly, I'm not familiar enough with dirty old Nissan comp covers to recognise it. It is definitely really old - Nissan comp covers have had flanged outlets for ages. I can't even get a handle on physically how big the turbo is. Wide angle lens distorts percpective. Hopefully someone else can use the information here.

Give photos of the compressor inducer, turbine exducer, turbine inlet flange, casting marks on the comp and exhaust housings. Write out the numbers you can identify on that core tag. We can't see them clearly enough on the photo to be sure about anything. Measure diameter of comp inducer, turbine exducer. Measure OD of comp wheel and turbine if you can. Verniers are cheap.

No, it will be boost sensor or TCS throttle sensor or something that hasn't been dealt with correctly in the change.

Just drive at 3750 rpm in 5th and double what you see on the speedo?

Stock ECU? Should not have done it. As in, you should not have put an FFP on it. Change it back or change ECU.

Just contact MV in Adelaide and ask them who they would recommend to fit their kit in Sydney.

yup

Centrifugal chargers are for girls. Big twisted rotor or GTFO!

There's another switch on the side of the gearbag, looks like the reverse switch. THAT is the neutral switch. What you have pointed to as the neutral switch is just the loom connector. But more importantly, that gearbag doesn't look like an RB25DET box. Looks like RB20DET. That lettering cast in in behind the reverse switch says RP71, right? Compare with below image of RB20 box

You take that back. That is the best thing done to an F40 evar!

There's on little increase in the hole's width at one end. Like it has been corroded a little. Hard to see what's actually happened.

Input shaft bearings don't like lots of torque. Your typical boosted RB25 is too much for it. I wore out 2 of them on an RB20. Yeah, even that's no longer true. Anything at that price will need the other $3k spent on it!

Yuh, I think that's pretty much the extent of it. I should have bought a 33 one when they were only $3k. Now I wish I bought a 34 one when they were <<$4k. Expensive future proofing shed ornament .

Well the R33 box is probably hard to get. It's OOS at JustJap for example. The R34 box is available there for >$4k now. Same same, but different. These or the R33 may be available at overseas Nissan parts people (all the usual suspects) for $3.5k but would have additional costs to get them into the country. Doesn't really matter. $3.5k. $4.5k. It's all about the same amount of money. If you want to play, you have to be ready to pay.

Yuh, what's the point unless you're broke-arse and have access to free Nav parts and capable of the required work? New box is new. If I were going to put time and energy into f**king about with alt Nissan gearboxes, it would be to go CD009 and get the extra gear.

It is in your head. The viscosity difference at operating temp is 3/5 of f**k all.

Literally on the first page of this very forum https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/?do=getNewComment

TD05 is not a new turbo. It's an old Jap design. Used on Mitsus, etc. Kinugawa are just making "new" copies of it, with different wheels, etc. Why not talk to Tao about what he can do for you?

And it is always way too hard to do your own wiring.

GT is the next to bottom NA car. GT-V was halfway to GT-T, whilst still being NA. Had A lot of the chassis/driveline differences from the GT-T on it.
