If you stick with the full VVC, you will need to do some cutting and soldering on the wiring, my mate Pete knew what he was doing, and understood it all, I didn't, but in the ned it all made sense, it was about splicing in the VVC engine loom to the rest of the wiring loom. Ditch the VVC bit and some sensors come off, which probably means even more hacking, but Mankee can probably best advise on that bit as he's done it. My engine came out of an MG ZR160, complete with engine loom but the ECU was wrecked in the crash that killed the car. I got hold of a VVC ECU from another local member, and got it checked for the correct map, and had the immobiliser matched to it, by a mate of a mate of a mate. I can let you have his contact details off line. One other thing, SM25T says about the plenum, I had the aluminium one, as oppoesd to plastic, and I had to get it machined to fit under the bonnet, even with the correct engine mounting, lets say it's still a snug fit. Good luck
