Hey all

i was sniffin around the RA site the other day and it had a 20b on there and i looked around the rebuild of it and it said that it was a 13b with an extra housing 20b ecentric shaft and 20 b intermediate. so has anyone tried that? or did i read it wrong?

 

That is exactly what i have in my car. !3b parts are far cheaper to pick up than 20b, all you need is the crankshaft (I can get these made) and then make your own exhaust and inlet
