also, i see your thinking about it, stop thinking and start doing, seriously once you've stripped out both cars you will have a much much better idea of the task(s) ahead, i then usually categorise tasks into how long they will take and which days i can squeeze them into, and try and stick to it, so:
1. i want engine out of UT on Saturday.
2. i want engine out of yugo on Saturday.
3. I want subframe out of UT on Sunday.
4. I want subframe out of yugo by Weds eve..... etc
Good advice!
Biggest problem is that there ISN'T a subframe in the Yugo!
I reckon best way is to buy another Yugo like the 55 I suggested that has the same engine type. Then it will just fit straight in.
Otherwise yes, just fit the Uno Turbo engine and box into the Yugo body, only three engine/gearbox mounts after all, can't be that hard. Make the Uno Turbo suspension fit the Yugo. Or make the Yugo gearbox fit the Uno Turbo engine. Those are the choices I see?
