Right iv noticed there are plenty of rx8s cheap and I'm looking at making a little hillclimb car and wondering whether an evo engine would fit in? Thanks any for any help.
It's obviously not an Evo engine so may not be any help, but Reyland were listing an adaptor to connect the RX-8 gearbox up to the 20v VW engine. Might be worth considering unless you are dead set on the 4G63 and/or already have the engine.
