cain, i ran one of those 2 years agon and really liked it...unfortunately, it was my first engine and therefore lived a short but fast life i ran the stock sportwerks 053 pipe with the u-shaped manifold and i wasn't ever left wanting for power anywhere. their very first run of engines had some small issues (funky acting low end needle, the occasional bad bearing and premature rod bushing wearing out) but nothing out of the ordinary. i clutched it with mugen carbon shoes, 1.0 springs and a 14 tooth clutch bell. rb#6 plugs worked nicely in it as would o'donell 99's.
