need help modifiying 4g63nonturbo

[mirage82]

hi there guys.

im from the philippines and right i have a jdm 4g63 non turbo mounted on my oldschool mitsubishi colt mirage 82 model. my 4g63 non turbo came from an RVR and a 7 bolter flywheel. the engine is very STOCK.

what i wanted is to modify my said engine but still i can use it as a daily drive sleeper :). but i dont know were to start, i know that Intake -Headers - exhaust are the first basic things to do.

but i want more, so i have to change my stock MAF to that of an evo (609).

what about the internals specifically the head. thats what i want to know coz i dont want to buy things/parts that i cant use or might be useless later on or not actually needed for that matter.

i know that i cant compare my HP to that of a 63 turbo. all i wanted is to at least max out a bit of my power on my 4g63non turbo. :)

thanks a lot guys in advance.

more HP to all

what gear box u use?

 

[mirage82]

@ sir UnicornSpeed, if your familiar wiht the mitsubishi mirage 4 door with a 4g11 engine, that's the tranny im still using STOCK tranny (2 type- 1 with econo shift, & mine doesnt have one but still on 4 speed) sorry sir, i dont have the tranny code so i dont know the exact gear ratio.

but just to give you an idea (i dont know if this will help) on a quarter mile run, i can go or cross the finish line only on 3rd gear and @ more or less 130-135 kmh. time is 15.8secs

:)

@sir UnicornSpeed, whats the difference between a 4g93 dohc tranny from the 4g92 dohc thats aside from the LSD from the 92?

is the gear ratio different? if ever we disregard the LSD thing, which tranny is best for a non turbo 63?

thanx again sir. more power
