MR2 1MZ Build Help.

Hi mate
 
I've done this swap. It all went to plan until I found the engine I'd bought had a scored main bearing. So I've had it running for about a week before I stripped the whole job apart to rebuild the motor, as a consequence of diagnosing the problem I've taken a 1MZ in/out half a dozen times now . The build thread is in my signature below.
 
Now I chose an aftermarket ECU to run my engine so the splicing together of the loom was quite different to what you'll be doing, there are people here who have done this or are in the process of doing it and I'm sure you'll hear from them.
 
Also I've used an S54 gearbox and I assume you'll be using the E153 already in the car so you won't have the problems I had there. You'll need to either reverse the flow of coolant with some creative plumbing or change the position of the temp sensor at the radiator side.
 
I can offer you some helpful links.
 
Twosrus sell the flywheel you need at about the best price I ever found http://twosrus.com/catalog/index.php?cPath=22_138
Here's a good build thread that I referred to a few times www.6gc.net/forums/index.php?showtopic=77116
Twobrutal, it's the best resource for these builds by far http://www.twobrutal.co.uk/forum/
 

No worries. The ECU was wired in with the help of some friends with more auto-elec knowledge than me. It took between the three of us at-least 8 hours to do it, including brainstorming. The main problems we (they) had was with splicing into the fusebox and body loom. So I have the MR2 body loom, 1MZ engine loom and the Adaptronic loom all splicing into each other. The details of the job are beyond my comprehension.
 
I'd suggest sending the whole lot off to an auto elec and prepare to pay a chunk of money to get it done properly. Now I'm not 100% on this but I believe if you're running the stock 1MZ ecu then you'll also need to wire in the immobiliser to the ignition, which I'm told is not a simple task. That's something I got around by going with an aftermarket ECU.
 
I'm using an S54 transmission with the original driveshafts, only minor grinding required on the 1MZ block to clear a driveshaft.
I'd suggest starting a build thread in the showroom section.

You fell in to a 'build thread worm hole'

They can upset the space/time continuum. Last time it happened to me i ended up on a german airstrip watching a turbo 1mz conversion.

OK, this thread has derailed somewhat, might as well continue the off-track experience a little more.  For those of you with a little time to kill, and in need of a smile, I present for your entertainment and education, the Picolax thread - an oldie but a goodie!

Do NOT drink any sort of beverage whilst reading this.  You have been warned.

MRvirgin used an Adaptronic Select ECU, a good choice IMO ;-)

My e420c was about $1000 including the loom. The current model (420d) is a little more so it'll probably work out at around $1050 http://adaptronic.com.au/products/e420d.html. You can fit the fidanza without having to balance anything else.

Well he's a mechanic and I'm not so you'd best use your own judgement. But yes I am sure.
