alpine04 Posted June 4, 2013 Report Share Posted June 4, 2013 so my banshee blew up, shattered the skirt off the right piston.so while i have it apart im going to build up a 4 mill. was just wondering if theres anything important i should know besides getting a spacer plate or domes and having my cylinders ported for it. and i was wondering where the best place to order my crank from would be? thanks Quote Link to comment Share on other sites More sharing options...
toytech Posted June 4, 2013 Report Share Posted June 4, 2013 If I ever do it again I will get cub cyls, only cost's a few more bucks then porting and boring. cheeta cub and 4mil crank. call Jeff @ FAST Racing he'll set you up right!!!!!

oldskool Posted June 4, 2013 Report Share Posted June 4, 2013 well, if your going with a 115mm rod on your +4mil crank you should get the 795 series wiseco piston or equivalent. 110mm rod should be the 513's i believe. Without spacer plate the domes need to be cut for the extra 2mm of TDC. Your gonna like it!! Quote Link to comment Share on other sites More sharing options...
