ZZP claims the base z3 Kit would take an L26 from 200 to 300 crank hp. %20 power loss through the transmission... 300 *0.2 = 60. 300-60 = 240. Thats were I got that estimate from.
I never said that you needed plogs. He just asked about them. you don't need the Hv3 either to run the kit.
He doesn't have to put it all on at once. If he did it on the L32 he would have plenty of time to do it before he puts it in.
