So i've bought a Evo that came with a built/forged engine, the previous owner passed on the build sheet to me so i went ahead and had the internals checked of the motor by a good friend of mine. He dropped the oil pan and had a look from underneath the motor and the build sheet checked out.

Now the reason i am here is because i've grown tired of the 390 or so HP that it came with and thinking about going for more power with this motor. The build sheet is as below :
4G63 2.0 Litre
- Forged CP Pistons 0.5mm Oversize
- Eagle H Beam Rods
- Kelford 264/260 Cam
- SuperTech Dual valve spring and Titanium retainer
- SuperTech SS Valves
- Bosch 2200cc Injectors
- ARP Main Studs
- ARP Head Studs
- ACL Racing Bearings

Now i've asked around in my local area and i've had a friend whose motor running Eagle H Beam threw out at 580HP and also one at 670HP. Now what i want to know is, that how much HP would my motor be capable of? And what is the max amount of Revs i can push on this thing? Currently Rev limit is sitting at 8300.

I can look into changing afew things here and there such as camshafts,injectors or head studs etc. Not looking at crazy numbers like 800+HP, i'd be very much happy with 600 or 650HP if the motor is safely capable of it. Any help or advise would be appreciated!

Cheers,
Thanks!

them rods are junk i have seen them go with only 400hp so i would say any power you are taking a risk pull them put put i beam in there.

HP you can push a lot more than 390 hp but for the 4g63t tq is the limitation for stock engine everything above 400ish tq is dangerous. look like you are fully built and redline should respected you have spring does mean to rev 8300 as you are taking more chance. You didn't mention what turbo you have? so I can't tell you no number
