Just to keep you all posted. The motor I have got is out of an SP20. It has bolted straight in without any hassles at all. ECU and everything else has gone perfectly AOK. Picking the car up tomorrow. Have given the turbo idea the flick (maybe), found out that I'd need to replace the radiator and the AC to get things to fit properly. It all just becomes a massive cost very quickly. Although I may change my mind!! If I bugger my radiator and have to replace it then I will pop in a MSP Radiator and AC unit.
Found this info on another forum. If anyone thinks its crap let me know. But so far it seems to be the best info I could find that seems reliable. So many people say yes, so many say no. Funny thing is the number of people who say yes but HAVEN'T done it!!!!
