There's a pic above of the 2.0 K-jet lump in my 80... Same basic block as a G60 so quite an easy fit, just got to sus out clutch options as I want retain the G60 flywheel, one can get custom clutches made for surprisingly little, that's if I can't work something out myself.
My RS2 is really very tidy and straight but is actually awaiting a full respray and mechanical restoration as the paint isn't perfect and running 380bhp for 100K miles takes a bit of a toll on the drive train. I haven't got the inclination to spend 100's of of hours sanding at the moment so the 80 project is something fun I can get on with whilst breaking my Corrado...
I also have 1992 runout model MK2 Golf with a G60 conversion using the correct parts from a German doner car as opposed to cobbled together with Corrado parts, this doesn't need much doing to it other than fitting the fuel pumps from my Corrado as the one's on there are both dead from being stood for too long.
And yes, I'm very lucky to have that workshop, I'm a mechanic so do all my own work which saves a fortune plus I know stuff is done right, though it does take some of the joy out of working on my own cars. There's a saying in the trade "this job ruins a good hobby" but I'm taking some time off working at classic car specialist I normally work for to do my own stuff.🙂
