woodro77 Posted March 22, 2006 Report Share Posted March 22, 2006 just got all my parts for new top end and now i want more power,(did not install yet) thinking about sending my cylinders to passion for 12 port, do i need to get the 4mm stroker ,how much more power with the 4mm? i already bought wiesco pistons and bored my cylinders,with 4 mm i will have to get new different pistons, is the 4mm worth the extra money , i also saw the vito stroker , what is the difference between the hot rod and vito, vitos told me that i can run the pistons i already have , would just the 12 port alone give me alot more gains, also does anyone know any shops in NEW YORK that does porting? any help would be appreciated Quote Link to comment Share on other sites More sharing options...

bkabina Posted March 22, 2006 Report Share Posted March 22, 2006 A stock stroke 12 port will add a good bit more power and be very fun.The 4 mill is deffinetly worth the extra money,If you are willing to have it ported to match the stroke.I would suggest the 4mill 12 port,This set-up is putting around 80hp to the rear wheels. Pm Passionre on here and ask him all your questions or maybe he will chime in. Quote Link to comment Share on other sites More sharing options...
