I havn't had mine on a dyno as is. The way the cams are set it has good torque. I have carbies so things are a bit different. Often idles above 1000, but can get it down below 1000rpm if I try. It will put around town easy, but no power if I mash the throttle below 3000rpm. But if the engine is already singing at 3000rpm, I can open the throttle and LOTS of power (ok its not turbo or anything). It will rev to 8000rpm if I make it, but I have a small misfire at about 7500rpm and I'm not sure what that is yet. The way the motor is there is no need to go above 7500rpm really. There is potential for more rpm and power if fiddled with right. Havn't got propper 400m times, but from what I know it will do a 15 easy. You could get yours into the 14's with the right tyres and alot of tuning.
Don't worry about forged pistons. Just use 3T-C ones. Either 85, 85.5, or 86mm. But if your go big bore, like 88.5 or 89mm, you will need expencive pistons. The 3T-C ones will work out to be about 10:1 or 10.5:1 compression. But its up to you to measure and calculate yourself.
No need to stuff around with oil pumps in my opinion. just use what you got.
