1. yes use 8v clutch n fly. id put a new one on for piece of mind tho
2. yes just the bay looms, leave inside looms alone
3. abf doesnt have maf etc, need abf airbox and intake pipe
4. id remove engien with box still on it, the entire front end comes off so this is easy. the front lower engine support bar comes off too, i see loads of people leave this on for some reason which makes your life much harder. hook the engine to the crane, undo front mount bolt then lift engine till it comes off the mount, then remove front engine carrier. uno rear box and engine mounts then lift it off and forward
5. 16v manifold fits the 8v downpipe, so can do it leaving the rest of the zaust on. I find it easier to unbolt the manifold from the engine, but you could unbolt the cat from the downpipe then pull it off, then remove the downpipe and refit.
exhaust is narrower bore from the front silencer back, but this wont make much difference to the power. later on you could bolt a 16v/vr6 exhaust to your cat if you want though :)

Brilliant- virtually all the info I need now - one more question!!

If I do get a pre-96 one did you say I don't need to worry about immobiliser/transponder etc? I can basically just fit the ECU, bay loom and engine - bolt everything up then the car *should* start a treat?

What about the fuelling system? How do people tend to approach this for ease?

indeed, the pre-96 ecu has no immobiliser built in so it'll ignore the immob bits inside the car. but if you get a post-96 one its no big deal, as i say vag-com can match it for you. vag-com cable only costs £10, all you need then is a laptop.

fuel system is same between 8v and 16v, just make sure you get the 2 rubber lines from the fuel rail to the main under-car plastic pipes as they're different lengths

Its just pointless and stupid! :rolleyes:

It's not, sell my 8v for 1k if I can get that much
Find a 16v (will no doubt be between 100-200miles away if I could)
pay 1500 or so for one in this region,
pay 100 pounds petrol/insurance transfer etc.

So thats 600 quid diff and It may have unknown issues - at least I know what's up with my golf at the moment. Also if you're a spanner monkey like me you'd never turn an opportunity to have some fun down  :cool:

i was always told not to use an 8v exhaust as it will cause engine trobles

You buy a decent 16v for less than a grand!

Ignore Len he along with a few others seem to spend their days winding people up and causing hassle you would think they would get bored but it seems not to be the case.

At the end of the day it is your car and your choice what to do with it.

Good luck with it.

But there is a point, if you have spent a lot or have a really tidy car you know well then the next step is a engine conversion.
