by basic i mean running pretty much a standard focus rs spec rather than external wastegate, air injectors, ALS etc. pretty sure a focus rs mani won't run a t28. couldn't remember if it was the rods or the pistons that needed modding to fit. with the build i was planning i was gonna do rods and pistons anyway so it didn't bother me. was going to a bomb proof bottom end, and then crank the power up later
