Kwanza, Nik, MR2Swift I need your help..., Same stupid questions... Options

The idea:

Got ahold of MR2 4AG Blue top Engine.. Everything is included,then i mean everything i mean everything all the sensors and etc... it is from my friend car, and it was sitting tin his garage for ever, so he desided to get rid of it.. 150$ for it was too fair so im getting it....

The bottom end has some problems but i dont even care, as long as im on the route to convert it to 7AGTE...


The main Question:

Wiring is MAP based, it has all the sensors and etc etc... BUT, im going with Megasquirt and im going with 4 ignition coils (direct ignition from peugeot). Question - what else i should need to make the engine wiring work propertly with this setup?

Optional Question:

Is everything Bolt on with the 7A and 4AG head? power steering and etc? (i dont have air cond so i think this aint a big problem)...
What CR i should get using 4AGZE pistons in 7A block and using 4AG head? I knwo what ignition chamber on 4AG is more flat so less volume and as long as with 7A head i get the 10.8 CR what should i expect witht the Blue top head?

Thanks guys, i really need some info quick, cuz i need to make the desidion about this setup - is it worth all the hastle....

Are you going to be running an EDIS-4 setup for ignition?
