I am building a 1983 GPZ1100, with a MoTeC M4 engine management system =
and a IHI-RHB5 turbocharger.....

Since this a 2-valve motor and I want it to be some what streetable =
(preferabably pump gas), what compression do you recemmend, (1260cc), to =
reduce detonation I can retard the timing as boost increases with the =
MoTec software.
 Also will any great benefit be obtained with 1mm over-size stainless =
intake and exhaust valves?
 Is there any advantage to having the combustion chamber and pistons =
"coated" with the thermal barrier compounds that are available?( I live =
about 10miles from a place that does it)

regards
Steve
