Honda jazz? Wat happend to your Mousedeer from hell?
Anyway, I heard last time a ZTH ol-timer NOS-ed his jazz.
The Jazz pinged all over the place and later they found out the hi-compression Jazz engnie could'nt take 50 shots.
It was toned down to 30 shots if no mistaken.
Based on that NOSed Jazz reference, I guess if you're force feeding it, you might not even be able get past 0.4 bar unless you're willing to spend big moolah on internals and management.
The owner of that Jazz I'm talking about is very lengchai and used to drive a Skyline while he was in Ozzie land. *hint-hint*
