I have a 2006 Evo IX MR...yeah its clean too.. but that besides the point. I need more power. Keep in mind i am keeping the stock turbo. I currently have a HKS Racing Suction Intake Reloaded. DC Sports Downpipe. Greddy TI-C Catback. Changed tranny oil to BG Synchro Shift II Transmission Fluid. Installed 2-Pc. Shifter Bushings. I ordered a Hallman RX Manual Boost Controller. I heard you can't push the car past 20 PSI on stock fuel pump and stock fuel injectors. What does everyone think i should do to get more horsepower? Lower Intercooler Piping? Aftermarket Intercooler ? Cams? Please help! Would appreciate it !

 

you can push 23-24 psi on 93-pump with stock fuel pump and stock injectors

and more on race gas

 

LICP, Cams and a tune

 

alky
cams
good tune
more boost

 

I also have a stock clutch and flywheel. Whats good rpms to drop it at? I dont really wanna change the clutch anytime soon either? Whats safe? 4000 RPM or take it to 5000 rpm rev limiter and risk Fu**ing something up???

 

5k at least. Even that is to low. And dont dump or drop your clutch if you want it to last

 

headstuds
cams
meth
mbc
walbro255
act 6 pucks
flywheel
hard intercooler pipes

crank boost to 28 psi, get tuned
enjoy 11.5s give u can drive, thats enough

 

tune

 

headstuds are needed after 24 PSI ??

 

Getting more power in a Evo is no problem its seeing how deep are your pockets are, and do you still want it street legal.

 

i dont care about street legal, i want the most power out of a stock turbo and stock internals. just seeing what my options are. probably gonna get gsc s1 cams, cam gears, intercooler,lower intercooler piping. run 24 psi with 104 race gas. and do a full tune. Im allready illegal without cats. and i live right next to ams performance. so i think thats what im gonna do from what everyone is recommending ! thanks guys...

 

im sure ill need a walbro 255 and injectors with it !

 

Also do you have the stopping power and can your suspension handle it? I would strengthen up the brakes and get some Coilovers first before you get more power...

 

walbro 255 fuel pump
arp headstuds
cams (cosworth or other)
test pipe (if you don't already have one)
SS o2 housing
alky injection
and lastly, a TUNE!

That should net you a solid 60-80whp, no problem!

 

If you do a fuel pump and alky, your stock injectors will be fine on the stock turbo.
