"The tensioner had let loose like I thought. But there was a lot more than met the eye. Turns out that the correct tensioner bearing assembly was not put back on the engine when rebuilt. It was -0.5mm out compared to stock and with an incorrect washer behind it meant that it was out another -0.5mm. Those coupled with the bearing itself having 1mm of movement in it bringing the total to 2mm out. It now makes sense why the belt kept walking and wearing as a result."
 
I just remembered this post on MR2OC that might be of interest:

"Yeah, learned the hard way to ALWAYS check the machine shops work." That's definitely a good thread with some good advice in it haha.

Just a small update.

So I made a mistake and a not so cheap one of that with the manifold adapter due to not doing enough research.

Apparently Toyota moved the turbo over a 1/4" on the gen 3 engines which is enough for turbos to foul on the slave cylinder lines when using this adapter. The other issue was that the wastegate flange was on the side rather than sticking out the front of the adapter, this was a minor issue however that would be easy to fix through a bit of fabrication.



Any who I decided to bite the bullet and order the very pricey but nice ATS adapter. With having it arrived early this week I can begin to make some progress and get the turbo/lines fitted up now.

Not a lot of progress has happened unfortunately. I have the turbo etc mostly mocked up but have been waiting for fittings to bridge the coolant lines to the stock ones.

Things left to do before the engine goes back in:

- Finish mocking up coolant lines
- Heat wrap return coolant line
- Reduce the length of the oil feed line
- Mock up oil return line.
- Paint ATS adapter.
- Reinstall turbo etc with all gaskets and washers.
- Install ACT clutch
- Install new timing belt

As for the motor, you may be able to go to fair trading & at least ask about your options without paying. Uphill battle, but worth a try so at least you know you did nothing.

Still not much progress has been made other than having to fabricate a new oil return fitting after I broke the supplied one.

Currently am waiting on the clutch which is taking a while as ACT sent the wrong one. So I'm looking at a 2-3 week wait at the moment.

But here's a shot of the turbo mocked up on the engine.

The clutch arrived and is now finally bolted up on the engine.

Long time between updates but the engine is back in the engine bay and runs.

Tell you what, the clutch is one mean mother.... It bites incredibly hard! Traffic lights will not be fun haha.

I put the car on the trailer this morning and delivered it to the exhaust shop. So not long now till I get to drive it properly.

Then in February I plan to install the 850cc injectors along with this baby.



More fun to come; which I hope will involve some track time this year.

I like this update :-)

Nice work dude :) I've missed seeing the yellow 2 at the Sydney meets

Looking good deco.
Just a quick one, i know its not as tilted as it looks in the photo, but are you leaving the turbo core on the angle you have it in your photo with the lines mocked up??

As a rule of thumb, the core should be now more than 30 degrees off upright to ensure oil flows in, lubricates and drains out of the turbo core properly. It looks a bit too rotated in the photo, meaning the bearings (or bushings) might not get lubricated properly, and with the drain on that angle, you will have pools of oil build up in the core, which can give you a smokey turbo pretty quickly.
