This newest JP FX engine actually has many batches... It has modified and non-modified (only lightened crankshaft), standard or optional ceramic bearing, black or non-black engine for budget cut.
For low-end power you have to try Novarossi RRL3/5 since many people said it has the best torque...

i have about $250 to spend and i want a motor that is relatively easy to tune and keep running, but also competitive, stock motors are probabply what im looking at getting, im running against mostly stock novarossi's and sirio's. i just want the have the power off the corners to keep up and possibly run down the novas out there.
