You seriously want us to attempt to diagnose odd sounds over the internet?

No, it was a joke. They were "correct". I just feel that knob end is possibly closer to the target audience! 😛

The pulsey nature of the noise makes me think that it could be a manifold or turbo gasket. I otherwise agree with Duncan. Get a 1m piece of garden hose, stick it in your ear and use the other end to locate the source of the noise.

Adrenaline glands, or adrenaline glans?

Does this ever bite you? Like in slower turns where the suspension is compressed but not quite on the stops, where a track bump or kerb will kick the travel into the stops?

Nope. Jap threads are BSP by another name. JIS PT = BSPT (where the T means Tapered, not thread, as is commonly mistaken). Note that I don't know if the target thread here is BSP/JIS or something else either. But.... if you've got the original in hand, then you have all that you need to know. Just measure the thread.

👌

Could just have the foam stuck over the sense element. Should just pull it out and look.

Hmm. They do not appear to have the standard shape - ie, no armrests. I suspect that means you have to put the switches on a more vertical surface, which would probably suck balls for usability and aesthetics. I also reckon that CF is absolutely the worst material for a door card. It will inevitably get kicked and scuffed down where the speaker grille would have been, and the elbow rub marks will make the top of the card wear differently to everywhere else. I think if I had no option but to use them, I'd be putting a clear wrap over them, which would no doubt end up looking a bit shit too. Maybe just another couple of layers of clear coat so they can be polished a few times to get around the wear issue.

They're not necessarily compatible, even if they're notionally the same box, because there were many detail differences from year to year (series to series, really) on both the RWD and AWD boxes. Unless your boxes are the same vintage, you wouldn't presume that everything/anything in particular would be swappable. The real difference is that the mainshaft is not the same. The output end has different stuff hanging off it between the two cases.

Further anecdote. <10°C ambient this AM. At ~12 minutes after start oil temp was still just under 80°C. So, it would have been >60°C and reasonably safe to give it some load probably ~6 minutes before. Normal stable oil T is 90°C, same as coolant, which should be no surprise with the stock heat exchanger.

Agree with the above. To put it plainly - the stock turbo is good for ~200rwkW at just enough boost pressure to make it explode (<14 psi). Everything on the car that works with that - the fuel pump, the injectors, the AFM - all of these are only good to about that power level. Some a bit less, especially if old and tired. Some a bit more. But all about the same. The stock clutch will not tolerate even that much for long. The stock auto gearbag will raise the white flag at that power level too. The TD06 you're putting on is good for upwards of 260 rwkW, at substantially more boost. But even at the same boost as the stocker, it will make a lot more power. As Duncan said, if you put your foot down and ramp up the boost, you will push past the capacity of the fuel system to keep up with the air flow, lean it out and pop it. Unlike what Duncan said, I would expect it to start and drive. It is an AFM ECU, so it will measure the idle and cruising air flow and provide fuel for that just fine. And that's the danger. Because it should feel fine and it will want to go and when you do.....pop.

Me ditto except for not having an oil cooler and not offering data.

No. Not crimped on. Pressed in. There are little "clippy retainer things" that are also on there but they really don't do anything. When you have pushed out the original inserts, you have to push back in other inserts with the hole/thread size that you need. 14 out, 12 in, or vice versa, depending on which way you're swapping. You cannot tap 14mm threads into a 22mm hole (or however big the hole is with the insert pressed out. Read my original reply - tells you exactly what was needed. But in your case, seeing as you claim to have 14mm bolts now, just get some 14mm OD, 1mm wall thickness stainless tube and make spacers to go in the holes in the uprights and use 12mm bolts to suit the R33 calipers. Has been done by many others and is perfectly fine.

And speak to the engineer before you start the swap. He may put conditions on the swap that you don't want to or have time to deal with, and better to find that out before you paint yourself into a corner.

I guess the questions we need to ask first are; Is the vehicle currently unregistered? Has the engine swap already been done? Do you own this vehicle? Or are you proposing to buy it with an existing engine swap and also currently unregistered? The answers to these questions will describe the shape of the hole you're digging for yourself.

It doesn't cause a big enough torque cut for properly powerful engines. And yes, exhaust temp rise is undesirable. Fuel cut on a single cylinder is a really fine grained torque reduction. You can go from a single cylinder cut for one engine cycle all the way up to rotating cuts across all the cylinders for as big a fraction of the number of firing cycles as the engine will take without stalling. Yeah nah. Josh's ignition timing reduction would also have been dynamic in response to ABS sensor reporting slip, same as if it was done by fuel cut. Not perma-reduction in the map. Perma-reduction in the timing map is more in line with the not very good idea of programming in outright reduced torque targets in the ECU for the lower gears. That's no different to just knobbling the tune by any other means and making less power all the time.

Impossible to say. Get the wiring diagram. Make sure you have the same wiring as the diagram. If you have the same wiring, and it has continuity where it should, AND shit's not working.....then you suspect the alternator has a fault.

Standard (industrial) practice to mount pressure transducers higher than their tapping points to ensure that condensation (or any liquid) will drain back to the process rather than come into contact with the sensor element.

If you have power both sides, then yes, there is no earth. That wire runs through the alternator as the exciter, which causes it to start producing current, which it will not reliably do without the excitation. You can follow it on the wiring diagram to see where it goes.

If you have to ask, you probably don't have enough legs. Might need to go body snatching.

I'm not sure I understand any of that. R33 GTST front rotors are 296x30. R34 GT-T are 310x30. Not thinner. Are you mixing NA and turbo brakes in the same conversation, without specifying which is which?

The poor man pays twice.

It'll be the head gasket. Why would it be anything else after a coolant dump and overheat?
