I've just bought a MR2 on ebay with a damaged engine. The plan is to go with the 2ZZ engine.

I know it's been covered a few times but some things aren't all that clear as a lot of it is for American spec cars. I'm planning to do this conversion for as cheap as possible. I was initially going to buy a Celica 190 and break it for bits but I don't know if I want the extra hassle. I've found someone breaking one, going to get a list of parts.

I'll need the engine with ancillaries and gearbox, ECU, transponder thing that fits over the lock and the keys. Is there anything else?

I'm looking at the extra parts needed going by the MWR website

Dipstick tube - surely I can bend one from either engine to work?
Engine mount spacer - looks simple enough, i'll make one
Loom adaptor - There doesn't seem like many extra things that need to be wired, surely not needed?
Selector shaft - Is this something I can make myself by welding the 2 from both gearboxes together?
Reverse block out - not needed?
Manifold - I've seen this, looks really cheap. Anyone used one? Does it do the job? http://www.ebay.co.uk/itm/3213683377...%3AMEBIDX%3AIT

I'll be opening up both gearboxes and swapping the LSD over.

Are there any wiring diagrams knocking around for the conversion?
