os engines
 

i was just wondering if someone could tell me i have a v one sII with an os max .12 tr(p)-t but i want more power and want to put in the os max .21vz-r, but is the pilot shaft on both engines the same size so i can use the same clutch??

My next door neighbour has a cen ct4-s and whips me so i think this should even things up a bit what do u think??

You already asked this, and as I said before, O.S. .18 TZ will drop in with no mods at all, and will smoke that CTS4 if you have good enough gearing.

Yea, and if you can manage to get the power to the pavement instead of spinning up your tires.
