I'm planning to change my turbo tomorrow.
Not being a mechanic, my dad is coming up from Dover to Bristol to help me. This probably translates to him changing the turbo with me looking over his shoulder and passing him the occasional spanner and cigarette!!
I have a couple of minor questions that maybe one of you townie gurus will be able to answer.
1. Which side of the engine is the turbo?
2. Do I need to remove the floor pans?
3. Are there any pitfalls to look out for?
4. Any hints or tips for a smooth change?
I would appreciate any help you could give.
Cheers
Tony

Floor out, air plumbing out, manifold out. then disconnect oil & coolant lines, exhaust, and bottom mounting bracket. Easy! (well, sortof...)
Oh, he'll need an "S" shaped (obstruction) spanner or two, 12 & 14mm IIRC

also before starting the job either buy new oil and water return pipe gaskets from toyota part number, t15471-58010 and t16347-42020 cost£4.63 from toyota,ormake your own ,i used rover metalized gasket from rover 414 rokercover gasket.and spend some time cleaning descaling and painting all pipes i used black gloss hammerite looks realy good and still shiny even after 1 years hard use
also its easyer to remove whole turbo and manifold as i piece and work on it on kitching table

Interesting. On mine there wasn't enough clearance to get the turbo and manifold out together...

Nor mine. Stripping down on kitchen table! Very understanding wife you have there Mark.

Well, it's done.
Started at 9am on Saturday morning, it took about 45 minutes to get the floor pan out so we could see what we were doing.
As we didn't have a C-spanner or an S-spanner we had to take the manifold and turbo out in one and strip it down out of the engine bay. This did take a very long time as we had to make sure we mapped exactly what we took off and where they had to go back.
The main problem with taking the manifold and turbo out together was the long pipe that goes behind the engine block that attaches to the manifold by two studs with the nuts at the back so you can't get anything on them to undo them. Anyway after mapping and disconnecting all the electrics from the opposite end of that pipe and with a bit of wiggling and me straddling the engine we got the manifold and turbo out in one.
This had taken us upto mid afternoon! We decided that we would go off to try and get a c-spanner so we could fit the new turbo and the old manifold back in seperately. Anyway 2 hrs of checking every motor related place this side of bristol no joy.
We reassembled the new turbo and old manifold on the drive, including the pipe that goes behind the engine and wiggled, wriggled and manoevered it back into place. bolted it all back up carefully making sure we checked off everything that had come off. Had major headache with the oil return pipe as couldn't get the gasket and faces lined up properly enough to get the studs back in. After trying for about half an hour and dropping the studs in the bowl we were using to catch the oil from the removed filter a few times, I stopped and had a cup of tea. When I tried again after that they went straight in(Bloody Typical!!).
So we had it all back in with lots of muttered swearing and aches and pains in places I never knew I had. As it was now just after midnight, we left it there.
Sunday morning, we checked again that we had everything where we should have had it and double checked we had everything tightened off. We put the floor pan back and the drivers seat back. We left the passenger seat up so we could hear any odd noises or see any leaks. Started her up, she purred into life!!
Left her to get up to temp and then got underneath to look at the turbo to make sure everything was OK. Minor leak on the oil feed pipe but this just needed an extra bit of tightening.
Took her for a little run Sunday afternoon just to make sure all was now ok.
Topped up the oil and water and all is now apparently OK.
Sorry for the lengthy post.

Apart from the noise, you'll be able to hear the kids again now, any change to performance?

That troublesome pipe running round the back was the EGR. You could have saved yourself a lot of hassle by removing it and blanking off the inlet and exhaust manifold connections. Never mind - all's well that ends well.

Clive,
Seems to be a bit nippier and pulls away quicker.
For the engine to drown out the noise of my kids it would probably need to be loud enough to register as a small earthquake!!
Ian,
EGR, Dohhhh! Wondered what it was.
