Bigger crank questions

[DeJay1206]

I'm gonna be ripping apart my Blaster here soon.. I've been wanting to get a 3mm crank from Vitos.. Now, what is the biggest crank I can get without trenching... And will I need to get any different headwork or porting? I have triple exhaust ports and a head mod... I know I'll have to re jet... Would you recommend getting this... Not sure of how big the gains are.

the vitos is the biggest without trenching abd if you don't want to run the spacer plate it will need to be ported and a head mod done

The 3 is the most. You may have to trim the opening of your cases a little. You can run the spacer plate but it's better to get your ports and head setup for the stroke.

If the cylinder is already ported for a stock stroke crankshaft, the 3mm crank may bring the ring gap into the intake port if you don’t run the plate.

I've heard concerns over the plate leaking. I'm not overly concerned with it. How big are the gains, and will my triple ports and head mod affect anything?
