Yeah, a set of 1600cc pistons, crank, rods, block...
on german e-bay I saw. Only problem is that the guy won't ship it, he says pickup within 7 days of auction closing. He's located in Austria and I am in Holland a good 10 hours drive, closer than Norway but I'm rock bottom at the minute anyway.
So I have revised my plan for the time being.
I will build up a 1800cc bottom end and run on carbs. The car won't be according to the homologation as the Rheila golf, but at least there are other classes into which I can enter and get my setup right.
Then I can take my time to build up a sweet 1600cc motor with the second head and bung it in there when I am ready.
