M20B25 later or early

[reztat]

I know is a noob question but I really need the info. I dont know if is in the forum either. I just want to know what are the diferences between an early i engine and a late engine...

The only differences between early and late M20B25 engines that are significant are that later engine (from 9/87) have slightly lighter pistons and different bearings. The water pump, expansion tank, and hose routings are different, but those can be swapped from one engine to the other.

There is a difference between the early and late engine harnesses. When swapping a late engine into an early car, or vice versa, use the harness that came with the car.

Thanks a lot, dont u know if an early one could be a donnor for a plug and play extra budget stroker>? I curently have a seta engine...

I'm not sure what you mean by a "plug-n-play" for "extra budget stroker" If you intend to convert your SETA engine into a stroker you will need the AFM, intake & throttle body, injectors, head, engine harness, and DME from an M20B25 engine. Since the car is an SETA I think you will want the late engine harness.
