hii!
right, basically i already know how engines operate and all that malarky but ive never actually done it or seen it for myself so i want to learn a bit more about engines and what exactly the internals of one look like etc etc. so my plan:
buy an engine stand, found 'healeys' ones on ebay for 50 quid ish
get a 2nd hand GTi engine from somehwere of a similar mileage to my own.
completely strip it down and rebuild it on the engine stand, maybe a couple of times, just to teach myself really, obviously re-doing all the gaskets/valves and cleaning it out/reconditioning it as i go.
i have a mechanic friend that will lend a hand along the way.
then eventually when im happy ive learnt all i can and its rebuilt properly switch it with my own (which has seen better days).
my question is, for a straight swap, same engine code (same year, same plex etc etc i dont need the ecu, bsi, key etc etc do i? and does it need programming of the ecu or anything like that?
i understand that this is a learning experience, the chances are ill rebuild it and itll run rough, rich or not at all. but i have access to an engine crane, very skilled mechanical help from a friend, a unit to do all the work in and time! and as GTis arnt worth s**t anymore i may as well use this car to learn what i want to learn 
good idea or bad?

No, the engine is completely seperate to the electronics and despite the common misconception that you do need to pair them, it's quited hard to pair circuitry to a lump of iron/aluminium 
The main thing you need to know is the right torque you need to apply to each bolt/nut when doing them back up. And obviously if you remove the pistons to make sure you put them back in the right cylinders.

ECU etc will not matter as long as its a preplex engine you reuild.

This sounds like a good project. Good luck with it, and take pics of your progress.

the main thing to make sure is you put the cylinders back in the right way up :D.
On a serious note though make a progress thread. You can get advice then as you go along. It could even be converted into a how-to when you are finished

Re-bore, polished ports, tuned cams. there's a fair bit you could do, but all comes at a cost and I don't know how the ECU would cope with it. It was far easier to play about with carbed engines.

Good luck mate I would do the same as this if I had the space and time. A really good project and I'm sure there's s**t loads of information on here and the Internet on how to rebuild an engine, and what little modifications you can do,

Just buy the crappest worn out engine for as little cost as possible, strip it and learn from that. No point rebuilding a decent engine and if you intend on ending up with something decent, leave it to the professionals. There are so many things to measure accurately to make a good engine.
