150 promax to 225

[lloyde]

Is it possible to convert a 150 promax to a 225,most of the parts look the same apart from the ecu and heads ?

The front half is different ( 225 is 7 petal the 200 2.5 Pro Max are 5 ) never built a 150 PM but I'd guess its 5 petal also...My guess would also be the heads are the same too..

BTW: I answered your question in a bit more detail on the European Forum..

The 150 doesn't have anywhere near the porting of the 225, and the sleeves in the 150 have the exhuast releif slots.
