i cant say what you would pay to have it fitted, all depends what the person charges etc. AFAIK it will bolt into any v1/2 the engine loom should plug into your car and the ecu once again will plug straight in. so should be easy as.
also no guarantee it wont fall apart, it is the old engine from my car i replaced it with a forged engine and it was a good runner beforehand. i would like to think it will hang together but i cant guarantee it. Basically i would use it if i had a car to put it in.
if youre genuinely interested pm me and we can go through the finer points.
