NICE!!! thanks sideways. ive been involved with the aircooled industry for about 15 yrs, and the innovations there blow my mind. so i was kinda hoping for that kind of trend here. if alaniz has done it cool, but i think more should jump on the bandwagon. i wanna get more info on that head that you have. thats the kind of stuff im into, if im gonna do my car, its gonna be all the way. either way, i must admit you learn new stuff every day, thanks again for the info.
i wish JUN would get involved and make some stuff for our motor. 350 hp aspirated LOL. laterz all dave

sideways.... Joe is going to measure the cams for me so we can decide if they are worth using or not...... If they are useful maybe someone here in the states can mass produce them at half the price with better materials.

Alright, if proper precautions are taken, revving a 2.5L motor to 9K is not a problem. My step-dad has a a Ford 289 revving to 10K. That being said though, I don't think just rods, pistons, and a crank will allow for 9K. 
Personally, I wouldn't do any of this until you can afford it all...EMS, Headwork, ITB's. Otherwise, you'll just be throwing money away when you go back to Inline Pro for a rebuild of your blown motor.

Why would it need head work to rev to what the head was designed to rev to? Why would he need ITB's exactly? Sure his engine is gonna be choking but it's not exactly needed either. Plus they dont make ITB's with runners long enough for a 2.5L F20C.
A very close to perfectly balanced crank, rods, piston combo will let it rev to 9k no problem. That's where the problem lies though. Actually, now that I think about it a little, wouldn't that completely alter the timing?
I say kudo's for trying something extreme and good luck. I'm pretty damn sure you're gonna need it and a lot of $ in the future.
