putra in trouble

[speeddemon993]

to all the putra sifus...
recently i just port and polished the head and changed to mivec pistons.. my car still feels like stock.. today i just fitted a fuel regulator.. its still the same.. what else i have to do to make it a little more powerful?? i dont really have a big budget.. i hope all you sifus out there can help me out..
thanks..

hmm bro...normally after Port & Polish(pnp) + upgrade to hi compression piston confirm can feel difference...your car is totally stock?
or you got extractor,exhaust?

maybe you need to have an AFC to re-tune your car to actually "feel" the difference...after porting your head air volume and velocity is increased and there might not be enough fuel being mixed into the combustion chamber..

are you experiencing any knocking?

Bro i also think you need a proper fuel management unit... 93 block with mivec piston cr quite high liao cos i'm using the same setting, i had knocking before so put in emanage, but not enough fuel so change injector and fuel pressure regulator...
Just get a tuning gadget first and ask your mech tune it on road, if afr too lean then only change injector...

dat is what a wrongly ported head will do to u, hence y i dont do dis in any of the cars iam/was working on.

thank you all so much for the advice.. i really appreciate it.. i suspect that my car is running too lean as the spark plugs are white.. i cant go to a mech cause all of this modification i d.i.y.. can anyone tell me where i can get and install an e-manage?? thanks for helping me out bros...

Phew~~ DIY??? damn cool bro... i never try it... you can get at any slightly reputable shop, but pls go for those with good tuner... All the best!!

i dont experience any knocking but exploding sound coming from the exhaust..
some say that i have to get a gsr intake and a mivec extractor.. is that necessary??

It has nth to do with your engine unhealthy condition, only serve as a tonic to aid in performance, won't die without it... : )

Go and find a tuner, get Emanage, and dyno tune ur car. Im sure something went wrong with the A/F mixture. There's nothing to worry much about :)
