i need to increase the power of my evo (ur HELP)
Hello every one
2005 evo
my evo mods are for now
2.3 L stroker (TODA crank & arms ..pistons Mahle)
Turbo : HKS GT2ii7460
headers Megan
cut back Greddy
650 injectors
down pipe test pipe
272 cams HKS
Koyo radiator
K&N filter
ACT clutch & fly wheel
Arp head studs ..etc
walbro fuel pump
hks fuel rail and regulator
flash tune unknown horse power
Stock transmission gear
ecu original
please ur advices ...goal is 450 engine or 500 engine
best regards and looking forward for ur answers (Assistance)
what do i need to change? how much it will cost
whats the evo computer (ecu max can hold)

What sort of driving do you intend to do with the car? Will it see any track use such as road racing, etc.? Do you intend to upgrade the intercooler? How about fuel type: What octane gasoline will you use in your car(98 octane R.O.N.)? Is the K&N air filter a drop in replacement panel in the stock air box, or a cone-shaped filter?
Has your cylinder head been ported and polished, or not? Even with a stock unported cylinder head, the HKS 272 camshafts are a relatively mild grind for your long stroke motor. They have very low lift(10.8/10.2?). I would look at other cams, such as: GSC S2, Kelford 272, or the JUN 272's. Any of these three would provide considerably more power than the HKS 272's.
The HKS 7460R turbo is configured with an extremely small and restrictive turbine housing for a large displacement motor such as yours. If I am not mistaken. It is even smaller than the tiny MHI i6G 9.0cm housing. Also, that particular turbo has experienced problems due to a poorly designed wastegate actuator rod and a high failure rate from flapper valve warpage. As a result, I would recommend a somewhat larger turbo that is still a bolt-on replacement unit. The 7460 will probably get you to your desired power level. However, I would instead get something like a MAP EF3 turbo for example. Of course, you can't go wrong with a CBRD BBK-B, or an FP HTA Green(or Red) either.
The HKS fuel rail and the adjustable fuel pressure regulator look nice but they are unnecessary at your particular power/modification level. The Megan tubular header likewise was money ill spent. It yields only a marginal increase in power compared to a ported stock cast manifold and is furthermore, very crack prone. The injectors seem to be on the smallish side as well. I would go with either Fuel Injector Clinic(FIC), or Injector Dynamics(ID) nozzles in the 1100-1450cc range.
Last but not least, the combination of parts is important but the tuning of the stock ECU is crucial as well. The stock ECU will get you to your desired power level and way beyond. But, you are going to require a good tuner to get the most power safely from your particular combination under your extreme desert conditions. I recommend Chris Mellon at Mellon Racing. He will give you the absolute best ECU tune over the internet.

first of all I would change EMS after turbo and injectors
if you want 500awhp you can get them on bb black at 1.6-1.8 bar but you will need 1 more fuel pump, at least AEM EMS, and 1000cc injectors

the intercooler is HKS
the octane here is 97
ya everybody here is telling me to change the injectors to 1000+
running 1.6 bar
how can i contact chris mellon.
what will happen if i changed the injectors? to 1000 or more..what will the difference. sorry for asking but i bought the car like this. but i want to work on it
thanks alot

It's been proven over and over you do not need to switch to an AEM ems. Stock Ecu can make LOTS of power safe. For 500 whp area an FP black or MAP EF3 or 4 or perhaps a BBK-C will do. You will need larger injectors 1000's or bigger but don't go too big. A rewired DW 300 or walbro 400 will do it.
* sparky gave you great info. The HKS cams are going to hold you back. Try kelford or GSC S2 cams*
