hi guys. i have a satria 1995 model 1.3 carb converted to 4g91 fuel injection. i have put a K&N air filter, changed my piping to 2 inches, changed my absorber to sports not adjustable with lower racing springs. i just recently changed my intake manifold to skunk2 70mm for honda B16a and added a s90 70mm evo3 throttle body with a sard fuel regulator tuned to 3.5 and jasma fuel rail. there is absolutely no difference from before i changed it im very confused. spent 1000+ already and still no difference very sakit hati. dont know what to do. and when i drive on the highway at high speeds its very bumpy :s. anyone can help?

hi bro. i think the way u mod u engine is not really 'step by step'. actually u r using a high flow intake and oversized throttle body that only suit for highly modded engine. if your 91 is stock - head no port & polish, no hicam etc u wont feel any advantages in using those skunk2 intake manifold and s90 70mm tb. it might just decrease your power. trust me on this. stock intake and mivec tb can do the job.

but since u have spent and fitted in the intake and tb, all u have to do now is to support your current mod. port polished your cylinder head, put in racing camshaft and stiffer valve spring and also management. u might as well increase your engine compression by changing to high compression piston or change to thinner metal gasket and skim you cylinder head.

hope this help. arigatou.

 

[marcusloo3003]

thx bro that helps alot. but shit it decreases power? that sucks. i thought it would increase my power by alot..mivec pistons are just plug and play?

 

[MiTec-i]

agree with wat joe said...u already hav a good platform..now make it great!

 

[badguy]

really very hard to get this FICD...................where to get one??? in JB??

Calvin help?

 

[marcusloo3003]

alright guys thx for the info. ill see what i can about this. how much would racing camshafts cost? and can mivec pistons just plug and play? or do i have to mod anything else to fit it? i spent alot of my money on the intake and tb now pokai lo

bro joe, so it will be better if we just maintain our intake manifold if our engines are still stock?
What about using an intake from a 93?? will there be any difference?
Marcus,u were using a b16a intake before on ur 91?? u still have it? :)
Mivec pistons is slightly larger then 91 in diameter.. Block needs to b re-bore.

no need to worry, its quite a reliable engine.. FC is good.. power ok.. probably can tapau 1.6 stock if u do a neat mod and proper tuning.. the cam lifter sound is common for all mitsu dohc engine.. no need to worry.. it just need to be serviced.. or changed if it have worn off too much..

Yeah i agree with you mate that it is quite reliable engine.And the main reason i didn't get any problem because i checked everything in time and get it serviced...http://www.eastbaytrainer.com/el-cerrito-personal-trainer/

i think 4g93 intake has a bigger hole. 54mm 4g91 intake have smaller one. 50mm i think.

 

[ACQ2305]

That wud be the 4 intake thingy connected to the head or for the throttle body??
The size of that hole u mention? Scared might get con :P

i also using this 4g91 since 2000 after i buy my iswara, 1st i use da carb 4g91, not realy good 4 fuel safe & long distance journey..after that in 2003 i upgrade da carb 2 injection but use 1.6 single cam intake & wiring set. it's defficult to set 4 nice top run, alwys sempot2 then in 2007 i change fully hlfcut 4g91, nice run..then in 2010 i upgrade again with b16 intake, gti cam & valve spring, blok 4g92 mivec, 4g93 gearbox..from that i get a better performance but a little modified must be done on driveshaft & mounting to get a strong torque..4 now it's better after 11 years old of my iswara..:proud:
