I haven't yet got an ECU in the car, but one will come with the engine we're thinking of using. I'll make sure to do a photo-log when it comes to installing everything.
The engine we have in mind is the 3.0 L H1V8, which is about the correct size and weight to replace the original 2.4 L Honda engine. Its also a very capable unit, which can be made to match the original engine's power output. We plan to start with a milder tune(500 rather than 750 BHP),at least until we are confident with the car. We'll have to make a frame to take the stress loading between the bulkhead and gearbox, as the H1V8 is not really designed to be used as the main stress member.
As for trans, the car still has its original X-trac, but we are probably having to replace it with pneumatic sequential we can have built into the existing carbon housing. Then we can keep the original suspension pick up points.
