I'm alright for parts for the racer Rob,
still got the spare 323 block, complete std 325i engine and bits for a 320 engine.
Gonna use the 325i engine with a schrick cam for now with the throttles and management etc.
Build up a new faster engine for the future with the 323 block.
As for the 635:
Also on order are bilstein B6's and a coilover conversion kit to stop it feeling like a boat in the bends.
