Hi there, I thought I'd share with you my 924 1.8t 20V project.
So I came across a 924 2.0l with a blown engine very cheap. Well when I say blown, the internals were completely worn out. There was so much end play in the crank shaft.. and so on. I looked at rebuilding the original engine, but parts are hard to come by. So I thought about alternatives. People have suggested small block v8's but I'm only 21, so insurance on this would be even more ludicrous than it is already. SO. I bought a 1.8t AEB off eBay for not much money at all.
I wanted to use as much of the original parts as possible, including mounts and the original bell housing.
To begin with I modified the bell housing to fit the engine, but the modifications meant that the original clutch couldn't be fitted. So I had an adapted plate made up. Which meant I could pick the angle that the engine could sit at. Unfortunately I didn't choose this too well and there is no space to fit the turbo where it is supposed to fit, of course I realised this after it was all together D:

I used the original flywheel and designed a plug to fit in the middle so that that I could use the audi bolt pattern. Simply fitted this and drilled the flywheel. I didn't want any of the dual mass rubbish on it.

Stupidly I sold the original Porsche starter motor trying to raise some money for other parts. I bought another one but the brushes were worn out so I decided just to use the AEB starter. The adapter plate that I had made was designed to hold a starter motor although not the AEB one. So I had to weld and modify it slightly. But it works perfectly. (Excuse the 'frankensump' I'll get to that part later')

Here it is fitted.

The engine mounts were quite simple to make.. although they don't look the best. I have only just learnt how to weld! I will probably have them made properly one day.

The next issue was the turbo location and down pipe. The turbo had to be moved from the engine and the down pipe had to be made at a very difficult route.



The intake manifold I had made by a specialist fabricator who is a friend of mine, so he didn't charge me much. It is a TT intake manifold that had been cut and shortened in order to clear the brake servo.

To be honest. It's not that great compared to other conversions, but I'm quite happy with what I've managed to achieve. For me it is a process of getting everything working properly and then slowly going through and correcting/tweaking everything that needs it.
