revving the shizer out of that motre is never the solution. My suggestion...buy a GsR swap, they pull in 5th harder than your car does in 3rd. My cheaper suggestion, look into some of those older trannys from the glory days of d-series. The ZC had a pretty tight tranny, as did the Si CRX (the old school style), but I'm not sure if they'd bolt up. I don't see why they wouldn't though, anyone know for sure?
BTW: what did you run?
