but throw enough money at anything it's no longer a problem I guess.

that said I've seen genuine 167fmm (in gray) for under 500$ sold from within the US, I'll try to scare up the link.

zorge is right for 750 its not really solving the problem.
for that I'd invest the time and a few more dollars and see to fit one of these with a similar engine mount pattern

4 valve ohc engines, likely has twice the power

hey zorge what this engine a clone of?
some Honda I think...
That is the water cooled engine that CSC uses in the RX3. It seems like a solid engine. I'm not sure if it's a clone of any one engine. It seems like a culmination of several.
