Mate by the time I import the parts and the stuff ups I'm likely to make I'm just better off buying complete I got a 4mm 410 with trinity porting but wanting more and oh yer busted a rod from undersized pistons when a mate did a overhaul for me so lesson learned but I want to do the dirt drags they have locally here plus there is a beach race as well laps around a couple of barrels so I'm wanting part drag to be a lot more competitive with that I was thinking big cube on pump with no override would be good but like my status says noob so any advice would be awesome guys
