#1: Engine strip down and rebuild Author: Kersh, Location: Bridgnorth, Nr WolverhamptonPosted: Fri Mar 25, 2011 5:00 am ---- 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?

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.

#6: Re: Engine strip down and rebuild Author: Kersh, Location: Bridgnorth, Nr WolverhamptonPosted: Fri Mar 25, 2011 5:33 am ---- yeah will do! got my eye on a few little tuning upgrades as well i may include in the build, nothing major
#7: Re: Engine strip down and rebuild Author: Rob2859, Location: HalifaxPosted: Fri Mar 25, 2011 5:49 am ---- 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
#8: Re: Engine strip down and rebuild Author: Kersh, Location: Bridgnorth, Nr WolverhamptonPosted: Fri Mar 25, 2011 5:50 am ---- yeah i will do lol!
need to find an engine/car now to disect
anyone know of anything?
#9: Re: Engine strip down and rebuild Author: macca1411, Location: Westhoughton, LancashirePosted: Fri Mar 25, 2011 5:53 am ---- 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.

Minor head gasket failure as far as I can tell.
#11: Re: Engine strip down and rebuild Author: Kersh, Location: Bridgnorth, Nr WolverhamptonPosted: Fri Mar 25, 2011 5:57 am ---- yeah im more bothered about just learning about the thing really. but well see what happens!

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,
#13: Re: Engine strip down and rebuild Author: Kersh, Location: Bridgnorth, Nr WolverhamptonPosted: Fri Mar 25, 2011 6:18 am ---- cheers mate! yeah it should be alright, be nice thing to learn about anyway, and the best way to learn for sure!

you have a PM!

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.
