4G93 dohc is distributor-less, its running on coil-packs.
-I heard that ppl say 1.8 change to MIVEC head, wat mean ah?
This means using a 1.8 block and the mivec head for a hybrid. you basically can use either full mivec wiring + ecu and u need to rechip it for proper air/fuel and ignition tuning or use a piggyback. if you use 1.8 ecu, you need something to activate ur mivec. some ppl i know use shift light to activate the mivec when using 1.8 ecu. u also need to rechip for proper air/fuel and ignition tuning. by having the mivec head, u get the best of both worlds. you get good decent low-mid end power. then once mivec engage, u get the feel of a 300/285 high cam.
-How about HIGH CAM?
high cam means higher duration + higher lift. usually 272 degrees and above. the sound that you like is the rough idling sound because the overlapping is alot, which kills ur vacuum at low rpm. not to mention, it also shifts ur powerband to higher rpm range which means u get poor low-end power but better mid to high-end power.
-Any other way to mod my car?
best is to understand what you want and what is ur budget, then plan accordingly. for example, just camshaft alone there is so much info you need. for example, what would be the ideal duration and lift at 0.050, the lobe separation angle, so u meet ur requirement on where u want ur powerband to be. then u need a mech to dial in ur cams according to spec.
