RE: OS 28xz or LRP zr.32
Ah, i see, ok got ya a bargain there, nice.
As you found out yourself, the OS is a racing engine. The LRP engines are bashing engines, loads of power, easy to tune, but not that economic with fuel.
I think, you can´t really compare these to engines, because they are normally in different price segments. If ya browse the forum regarding the LRP engines, the feedback ist mostly positive.
Hell, i think, even the LRP ZR30 is more than enough power for a basher.
