hang on hang on....scrap the throttle bodies idea....
the 1.0 wont be able to utilise the potential of throttle bodies...
what you want is a set of GSXR 750 motorbike carbs.....
these alone can see the engine revving to well over 9.5K rpm.... with well over 110BHP....
add this to a skimmed and gas flowed head and some high compression pistons and you are looking at about 150bhp or even higher....but will be at about 10,000rpm+
good luck by the way..
and the previous post is pure speculation..... no CG13DE engine outside of taiwan can produce anywhere near 200bhp N/A...lol
