Thanks Yonex, I'm afraid its nowhere near the progress of my last project, but if you don't mind slow and steady then I should get there in the end.


I spent most of this morning pulling the last few bits off the toledo, the first length of exhaust pipe, the gear linkage and a few nuts and bolts. I put the bumper back on, and the bonnet. Drained the tank and put it in the daily driver.

Then out came the Scimitar and in went the MR2. I've taken a few bits off it and had a good look over it. I think I'm going to do something like what I did with the Toledo. Label everything up as I disconnect it, take the engine and box out, then open up the loom and check there is nothing in that stretch of loom that I need.

So this is where I'm at at the moment. It still doesn't look like much progress, but I really have run out of other things to do now smile

This might sound strange, but I really like working on Toyotas, this is the fourth Toyota I've worked on and they just seem to be well put together. Everything is in a sensible place, well made, dimple topped captive washer bolts, and well thought out.



More to come.

If you don't mind the question - what made you pick the MR2 over an alternative coupe/sporty body?

It seems like an odd choice to fit a diesel in, when the sound is such a big part of the driving experience. Are you planning on adding a lot of insulation to block the noise of the engine?

Good question.

I've always had a soft spot for these, I had a mk1 before, and a mk3 supra and loved them both.

It had to be rear drive as I don't really like torque steer or the way that front heavy FWD TDI cars handle. But with RWD comes extra cost with a project like this. The MR2 solves both of these being a transverse rear engined car. Antoher car I have a soft spot for is the 3 series TDS E36. It was a toss up between the two really. I think I ended up going withe MR2 as it was the most unusual project.

Yey! I got more done today smilesmilesmile

Got the MR2 motor out. I've said it before and will no doubt say it many more times... I love working on Toyotas.

Another bit of good news is that I found the TDI engine is 3 inches shorter than the MR2 engine so there's plenty of room smile





Having had a good look at the two, I think I've now got a design in my head for how to make the toyota engine mounts fit the TDI engine.

More to come.

I'm sorry, but this is wrong... I know that this is a labour of love (sort of) but still i don't believe that this unit suits this car well. Sort of ruined car grumpy

I disagree. It isn't like the world is short of MR2s and this is a really interesting project.

Keep the posts coming please smile

I took a day off today and was in the garage all day smile It was like old times, a pig in s*** smilesmilesmile

I made another 150L of bio diesel. I stripped the Toyota engine loom in an attempt to understanding it and see if I could get the engine bay fan to work in the absence of the engine (I couldn't). So the engine loom now consists of just the reverse light wiring smile

Then stripped the loom to the dials and have identified what I need to make the following warning lights work: main beam, fog lights, handbrake, doors open, and indicators. Then took it to pieces and was delighted to find that the VAG dials will fit in the gap where the Toyota dials used to reside. Result!

As well as that, I've done my usual looking at it for ages and figuring things out, got lots of ideas in my head now. What a great day! smile

interesting project, dont suppose you see many oil burner mr2's around, ignore the people that are getting all precious about 'ruining' the car, plenty of mr2s have been ruined by veilside kits and fake ferraris so do your own thing and enjoy it, after all its your car and your time/money.

There is a lot of heavy bracketary on the toyota lump, I mean a lot and the TDI motor is 3 inches shorter from crank pulley to gearbox end, so I'm confident that it won't be that much heavier than the toyota motor smile

alternator bracket on the mr2 3sge engine weighs about 8kg on its own - massive lump of pig iron

oh and you won't need the power steering pump on the new engine so a little lighter already

A little update on my (lack of) progress smile

I've not done a huge amount as the clutch on my cr**y 106 diesel failed in a way that meant it wouldn't disengage. So I've taken the gearbox off that and am waiting for a new clutch plate to arrive.

Spot the piece of metal where it shouldn't be......



On the plus (but rather expensive side) I'm driving the scimitar 90 miles a day, getting plenty of admiring looks and really enjoying the car (at 5 times the cost!!!).

Back to the MR2, I've been doing a bit of loom thinning, this time its the TDI loom, its about halved so far, I need to go get some of the controls to keep going with the job now.


More to come.

It Runs!!!!!!

After several weeks of head scratching, a friend at work gave me a circuit diagram from autodata (thanks Mark), and it seems I had an earth connected up to 12v. I changed that and it ran straight away. See the video here:

https://www.youtube.com/watch?v=O6V9oazx_HI&fe...

Its very nearly in a position to be electrically connected to Mr Two now, I hope to have that done soon, then I'll get started on the mechanical side and physically putting all the wires in the car.

Very happy with that.

More to come.

Thanks Folks, it was quite a relief to get it to run. It still runs a bit rough until I pull one of the fuses out, then it runs smooth but without the dials working. What fun! I'll hopefully get to the bottom of this at some point.
