Awesome GTI tuning this week!
Hi mate, sorry to hear about your bad luck.
After suffering an engine failure on my S3 8L (1.8T AMK), I bit the bullet and changed the whole engine (to a BAM). But it cost me well over £3500 in rebuild/parts/clutch/flywheel/turbo labour costs. Unless your clutch, flywheel and turbo are in mint condition, it's best to change these too at the same time as afterwards it's just going to cost you more. Plus the donor engine will probably need belts/chain tensioners, oil pump/ pickup, gaskets, engine mounts, other ancilleries too so it all adds up.
Personally, I'd break the car, recover some of your costs and buy another car. Sounds harsh but otherwise you'll end up spending in total more than the car is worth and never get your money back.
That's why my car hasn't sold and now I'm forced to break it AFTER spending all the money on repairing it - for a greater loss. Many people won't buy a car which has had the engine changed. Plus you need to know for sure the engine is genuine, not stolen as the DVLA and insurance company need to know too....
