I would just call Hamilton or colt whichever you prefer and talk to them about your goals. I'd personally say if you plan to upgrade the turbo slightly and want power and grunt a 181 would be the choice but there may be better choices. I think the 178/208 is supposed to be better for a more mild towing type set up.

 

and yes with what 94 posted the hamilton would have less overlap.

 

Oh I don't see a problem then. Seems like it's a pretty good idea then. Only downside is like over speeding an undersized turbo like what I'm gonna do haha

 

like everything there are several things to consider. duration is one factor in a cam. it is a good idea thats why we put cams in things but in moderation and in conjunction with everything else that makes the little engine go vroom.
