The axle has been upgraded by Mark at Jigsaw with err (can't remember) but he is running a Le Mans GT6 with the same upgrade at 200+ bhp, so shouldn't be a problem.
The Z16xer is a 1.6 and alot smaller and lighter than the C16NZ2 that in standard form puts out 115 - 120 HP but been informed that with after market ECU and a bit of tweeking 150 should be about right?
