I’m doing this conversion too, I’m just about at the water conversion & ECU stage. I plan to make my own water relocation kit, I’ve found a pinto thermostat housing is a very close fit for the top hose outlet, however the hose points in the wrong direction so you will need to be able to weld alloy to use it. (it’s hard to explain without pictures, ill do a guide with pictures when I get around to fabricating everything) Here is a good guide -
http://s-86.com/s-newcoolingguide.html Regarding the ECU, I’ve got a OMEX 700 that I got a good price on second hand, I’m doing away with the distributor altogether and using a front pulley mounted trigger wheel and COP’s from a yaris, (They need slight modifications to fit.)
A megasquirt ECU is a cheaper alternative, but unless you’re prepared to do everything yourself, hours of research, and a lot of figuring out and problem solving you won’t save any money. If you’ve got loads of spare time the MS system is great, brilliant even, id recommend it to anyone as the best way to learn your way around ECU systems, but if you’re not reasonably computer/electrically competent and don’t have loads of spare time it’s a total ball ache. (That’s why it has such a bad reputation in some circles)
Talk to Raw Engineering, I think they do an off the shelf Omex kit, or they will at least point you in the right direction and give you an idea of cost.
