The drivers side belt on mine was tired so replaced it with a new one from Mr T. Two years ago, it was around £60. Trouble is, it's almost as bad again already.

I would have been more tolerant with a nuts& bolts job, but can't out think electrikery Gremlins when I'm to cold to think straight.

No rain and only light winds today so I had a go at the electrickery. However, In my enthusiasm to get on with the job I had ignored the other element and soon became so cold that all I wanted to do was stop, so I did.

Cue Straightsix

That would be much easier and the route I would have taken if I had the luxury of a second car.

Maybe the filter at the bottom of your PAS header tank needs cleaning? Do a search on that.

It's the lowering that's done it, you need a full geometry set-up. (6 years 5 months 2 days. Great revival )

The first comes last.

Edited. The Toyota blower is the same displacement as an M90 but doesn't live very long when pushed, I've read 7-8 psi is as far as it's happy.

Both doors, rear-hatch and bonnet/alarm will all trigger the light. Getting warmer, slow rotation = slow bearing = wheel bearing or drive-shaft bearing or high-gear in transmission? Clutching at straws though, you must try harder.

Close the door/check-switch and press the button on the gear-knob and the Christmas lights should go out. Sounds like a bearing, but you'll have to try harder than that to explain your Gremlin.

P.S. Superchargers are silent at cruise and only whine when under boost, I love the sound of a supercharger at full-chat.

Rotrex kits are available for the 2JZA80-GE but they cost a fortune and there's not much space under the curve. Test on same engine. Extreme left from the top. 1. Roots 2. Whipple 3. Turbo 4. Centrifugal I think this 1G-GZE supercharger would be the easiest to transplant onto a Supra, it’s an (M90) Toyota made Roots charger and the 1G straight 6 cylinder 2.0 litre engine is not a lot different externally to the 1J and 2J engines and from what I have read it is good for 7-8psi. These units can be picked up in Australia for around $150AU

I've posted several times I'm itching to go and play with T.T's. and "Old Lag's" at Santa Pod, keep your eye on the build thread and you'll see when it's ready for it's first fight. I'll happily wager a pint and enjoy drinking one after, win or lose, I'm not betting the key's just yet though.

You be careful, I might request to park next to you sometime moja colleaga.

Since the ECU swap, there's one circuit I need to reconnect to reintegrate a Suprastick control function, then I'll plug both ECU's into into my laptop and see what I can see. Wiring is the worst job to do this weather, kneeling down in outside places regularly gets me dirty, wet and cold. Today, after doing up the fiddly nuts on the alternator job with my poorly finger whilst the bonnet was beating me up in the wind, I then spent an hour or so on my knees trying to trace circuits in the foot-well with the added wind-up of a hooligan regularly slamming the door against my bad back. First chance of neither rain nor high winds on hard-standing with mains-electric, I'll be on it.

Today I swapped the alternator, which has cured the previously, cold-engine only rattle I've been blaming onto the superchargers and it has also doubled the speed of the gear-changes. Because it was working, it's been a lower priority job than supercharging for sometime now. It's gratifying to "kill two birds with one stone". Three if fitting the new Gatorback belt is included. The Sky-hook bracket had to come off for the job, yet it went back on without need of the "Special Service Tools". Now shimmed into position, it's a plug&play 5-bolts job. I keep "finding" water/meth system upgrades and gizmo's, I now have both ERL Mf2 and fiA2. The Mf2 is a mappable flow control standalone ECU and the fiA2 reads fuel injector voltage and automatically flows the system fuel-parallel @15%. To stay within my electro-bamboozle limits I plan to use the automatic fiA2, I can later change to the mappable Mf2 if needs be. Yet before any further electro-gizmo add-ons I need to track down the Random Spike Gremlin. Whilst the supercharged parts of the job just get on with it. I was hoping that Dan would find the cause whilst he was mapping it. Yet the engine didn't skip a heart-beat all day, apart from one, just one, just before he was plugged in. I have been learning this Gremlins 'habits' and found that it happens not exclusively but mostly, between almost the same temperature range as the fan thermostat on a rising temperature, sometimes, and I suspect the engine-temp sensor is the culprit. Can this sensor be got at and changed without the PITA of removing the PAS pump and/or AC compressor? At tick-over at exactly at the rising sometimes-wrong temperature, it can work up a right "donkey" for a while. Now I've found where the Gremlin "Random Spike" lives, I've captured evidence on camera, both engine and rev counter. You can hear the timing-spike several times during the first 6 seconds or so of this clip, before the sound from the clattering-alternator overwhelms it, but I didn't catch it on the rev-counter. (Backing-track by the now-silenced, clattering-alternator) [video=youtube_share;YQcnF-JJhvI] Caught it on rev-counter this time. The red triangle is on because of a cat over-heat sensor incorrect reading by the AEM ECU, Dan said he needed to cut a wire, but we got exited and forgot. The sensor is plugged into the loom and stashed behind the radio?

I have taken a close look at this pic and the screw and fragments look to be brothers, the threads and washer are there but not the head of the screw and that's the piece you may still find in the same cylinder. It's not clear, but is there a little spring washer on it too?

Thank you for posting the W59 upgrade pic. Nice job on the bell-housing, I hope it proves to align well. When it does, you're going to be a busy man knocking those out. You're lucky you're so far away, or I'd be visiting with pieces of aluminium castings for you to weld together.

My money's on a bent valve this time.

I have confidence with my hand-mackled contraptions and weather permitting, straining at the leash to get it finished then go and reduce my creation to numbers.
