from what I gather, its an ST220 engine from a scrapped car, which cost about £800
its mated to his ST200 gearbox.
went straight in, with about 2 wires on the loom needing changing
thats all I know, he did have it up for sale, but Im not sure if he has sold it or decided not to as he hasnt posted in a while.
it will be in FF/PF mag soon as well
currently putting out about 245 bhp
