OK, I will go ahead with the ERP. I just thought $35 sounded like a good deal for a spare engine. I feel bad sending in the .16 though. It has been a great engine, I just like power too much.

Will the .18 SH have more top end, or will it be mostly low end/torque? Just curious, because as is, the .16 destroys tires off the line. Plenty of low end.
