Is the 1308cc my old engine? If so, Race Power Motorsport built it. Was built to rev to 8500 cleanly, karl-schmitt pistons, 9:1 comp. ecu chip limited to 8k at time. Though needs a change of camshaft to take advantage of the revs, as it only made peak ps at 6600rpm, cam was wrong spec. Found that out at end, could never get setup and working properly (cam, vernier, charger blowing seal springs constantly, alternator goosed, then piston rings (only lasted a few k miles, etc), as we wanted a peak ps at 8000 - 8200rpm . I had it rebuilt with stock rings after using a g-lader to use a gt25 turbo with jenvey iTB's and dta management but sold it to fund my house.
