I have non pro xs motor maybe looking to up grade to a 250 gram a 225
If you would, please take a moment to review the Announcements at the top of the Forum, and be sure to provide the Required Info (serial number) when posting. Thanks!
225 and 250 have completely different block porting, different cylinder heads, and the ProXS pistons are different.
Externally there are significant differences (Direct Injectors, Fuel Rails, PCM, Ignition, Spark Plugs, Reeds and Reed Blocks, Reed Plate, Air Compressor, Flywheel Cover and Attenuator Cover, just to name a few).
