Hi, this is just a general question about engine changes on cars which use ecu. Can you use the existing ecu and electrics with a replacement engine or is it best to buy electrics with an engine. I have a headgasket failure on another project, previous owner said it had piston replacement and new headgasket but obviously it didn't or it wasn't done well! I may do engine swop as a cheaper alternative to new head kit depending on what I find when I take the head off... yeah I know... at least if you rebuild the engine you know its done... you could buy another duff motor etc..
I am sure its a dumb question but all my previous engine swops have been on old Land Rovers and Triumphs, this would be my first modern car transplant.:confused:

So long as its the same size engine it will work using the original ecu!

Thanks for that info, wasn't sure if the inlet and injection system where paired with an ecu at point of assembly/manufacture?
Cheers,:thumbs:

Nope. Depends which engines but general Alfas are interchangeable to a point.

Basically its more or less essential to keep the car's own ECU - if you use the ECU that comes with the donor engine you will need its code box and ignition key, or at least the chip out of the kay, as well.
