check fuel pressure,check timing 10deg on idle.Plug in AFR and see on light throttle 14.2 and full throttle 12.5 for mitsubishi engine.

u can check with http://rossracing.fotopages.com

ummm 4g63 in US on Mitsubishi Eclispe is 450cc, i'm using that on my Prelude right now. more fuel doesnt mean u will get more power, the most power u can get is when your engine is stoichio. or lean, the problem is too lean = detonation. if u can get stoic. at all RPM range and Speed range thats the best.

When you put more fuel = rich, too rich you will lose power but your car wont detonate. In other words your car is running in safe mode.

and if u want to read the AFR, you need to use the Wideband 02 sensor kit not just the normal cheap ass AFR meter LOL. so yeah i guess "light throttle 14.2 and full throttle 12.5 for mitsubishi engine" is right.

But difference with Vtec engine.he need more fuel at hight RPM coz of hight comp.my be need AFR 12.0-11.6 10,000 rpm.

92p = 180cc (i think)
91 = 210cc
93 = 240cc
93t = 340cc (i think)

changing to bigger size of injector with stock condition will not bring u more power but lost of power.. coz u r runing rich!!! which u will get high FC also..
the 2.0 single cam tb rite?? is still the same bore size... actually is the same tb as 1.6 single cam1..

to safe yr engine,get a good power and perfect tune.U can buy the Microtech LT2 fuel controller it's small budget what u need.Only RM1650.U can used what type of injectors u want.And any upgrade from yr engine.

i thought the perdana tb is bigger than the 4g92p
but it look bigger le. nvm
what else can i upgrade beside injector by not spending too much
around rm500
im planin to change my crank pulley as well. where can i find alloy crank pulley for 4g92p?
the microtech LT2 is quite affordable compared to others
is it include installation????

 

[rossracing]

Complete installation aroud RM2000.For me Quality is the best,money 2nd.Nothing much from change the crank pulley.If u want u can check with Ngai Seng subang.
