I should be back on the dyno within a week with the "new" engine, and the new MSD BTM as well. Hooking that sucker on the S14 internal coil dist. was such a PITA! :smash:

cams, valve springs, and some computer tuning allow you to rev that high. thats what you need to do it right though

stock KA valvetrain can get up to around 7500. I dunno about doing it regularly.... :eek3:

JWT ECU's are normally programed to 7200 IIRC. Mine will be limited at 7000 when I get the MSD 6AL.

who says a KA cant rev past 7k, mine revs til i let off the accelerator, :D the only reason that you really shouldnt go above 7k is the KA crank has really bad harmonics around 7300 rpm and causes lots of problems, but i regularly rev my car to 8k when im at the track, mainly because i have a built head, i make power up there because of my cam and i dont care, :D my SOHC ran 140rwhp on the dyno, but my boss stopped at 6500 cuz he didnt wanna go higher, but the power hadnt peaked yet.
