Very tricky to answer since I don't keep a book and I buy big parts and use a little then sell on rest. But...
Crashed Punto with the engine in - £700 minus £1000 parts and car re-sold = -£300
Y10 bought for parts - £350 minus £150 car re-sold = £200
Exhaust manifold - £150
Coils and dampers - £300
There is probably a few other little things, but I have made it all mostly from the bits of Punto and Y10 otherwise.
When I first put the engine in, I had a running car for a profit, including buying the car! Lots of time spent working out how to fit bits in and wire it all up though.
I put the gearbox from the Punto in BTW. Only done 3000 miles so couldn't resist.
