Are the wheels locating on the hub centres properly (a good tyre place should know that requirement)?

60 psi is a bit too much - standard is around 37 psi, rising to perhaps 50 on full boost. So, the engine will be running richer than normal, and I've heard recently that too rich can also cause knock. Try backing off the fuel pressure a bit.

No-one seems to be concerned about the little earth tremor last night, around 10:40

No, they SEIZE. (Well, I guess when they seize, they cease.)But the Japs are famous for not using inhibitor in their cars, and the blades on the pump impeller corrode away - that's the more usual problem.

No. It is a matter that ALL forum members need to be mindful of. And I said it because a moderator didn't / couldn't / wouldn't.

You haven't stated if the engine has been modded in any way. Info like that is often useful in diasgnosing these sorts of problems. Idle "hunting" is likely the AAC valve - it's the little cylinder attached to the back of the plenum chamber. The flat-spot is totally unrelated to the AAC valve. It is likely the ECU is detecting "knock", which may be caused by a dying fuel pump. Get the car onto a dyno, with an AFR meter and a fuel pressure gauge.

They are all RB25DETs - so same performance (engine-wise). The differences will come in the weight penalty a AWD has, but that will be offset by the AWD drive and handling.

I have a set of 17x7.5s with 50% B/S GIIIs on them. But they are a +40 offset, so they'll sit too far in. Up to you. No payment required.

Which GTS4 (R32 or R33)? R32 GTS4 only came with a RB20DET. Stagea RB25DET is the only engine that bolts straight in (in RB25s at least - obviously RB26 is an option). As to performance, I took my low-mod R32 GTS4 from 115 awkW up to 180 awkW (included aftermarket ECU). You be the judge if it's worthwhile.

The "normal" RB25DET has a different sump pattern, so you can't swap your 4WD sump onto the RB25DET. The Stagea has a AWD RB25DET, but the manuals are like chooks teeth (the vast majority are autos too). You might have to settle for a GT-R gearbox, unless you can find a manual one from the R32 GTS4. Clearly, if you get a half-cut, then you get the good brakes as well.

The 260Z carbies are WOFTAM. Have you talked to Lindsay at Z Shop in Glen Iris?

Replace the fuel filter. A clogged fuel filter will allow the engine to rev its rings off in neutral, but as soon as you put some load on it, it can't get enough fuel.

BUGGA. Probably cheapest fix is to get a new engine from a wrecker - try John at J&S Imports in Seaford, 97750597. Talk to Daniel - 98082590 - (he's in Burwood) about fitting the new engine. Tell them Greg sent you (and they'll happily double the price LOL)

Had a similar thing with my old RB20 - I thought it was a sticky lifter, but after I sold it, the buyer advised me that he had pulled it down and there was evidence of piston-slap. Another possibility, since the noise seems more pronounced on the underside, is a dying / shot big-end bearing.

If you plan to simply fix and sell, then get a replacement from the wreckers and install it. Otherwise, rebuild the dead one - and ask to talk to previous customers of the engine builder if you have any concerns.

Randy, it's what the workshop manuals say, so it can't be all that dangerous. (It's only a problem under load, when a lean mixture can cause detonation). The rail is held in by 3 bolts. And it's not really necessary to separate the plenum - if you remove enough hoses and stuff, the rail will come out forwards (over the radiator).

Any suspension stuff, simply get GT-R stuff. I'm running Bilsteins and Kings lowered springs, with Whiteline GT-R HD rear swaybar. The best improvement of all - RB25DET. Torque to burn. Next best thing to a GT-R.

My thoughts exactly. Get a spanner (27mm socket) onto the crank pulley bolt and see if you can turn the engine at all.

YEAR: 1983 (12/82 build) MODEL: R30 BODY TYPE: Hatchback COLOUR: Silver Just fitted the L20ET, running a RB20 BB centre, and controlled by a Wolf 3D.

TPS is out of adjustment, and is not sending the 'throttle closed' signal to the ECU. Can't remember if it's pins 1 & 2 or 2& 3 need 0 ohms at "throttle closed".

Try Quadrant Suspensions in Berwick (Bilstein agents), or Top Performance (somewhere near Vermont?, Koni agents).

Calculation is correct. Maybe misread the vernier? Otherwise you have one lumpy cam there.

I would argue it was in a state of suspension within the last 3 years, so the answer has to be YES. But ask the insurance company.

Or "Speedometers". There's one in Mulgrave, IIRC. They stick a "black box" converter on the cable, costs around $175.
