I thought MIVEC needs RON97 petrol..
Better go for 4G91 DOHC.

mivec no need ron97, 95 also can.

Aira,

One word of caution. 4G13 gearbox is short ratio. Meaning if you plonk in a higher powered engine with your original gearbox, you'll have a considerably higher FC if you go on highways a lot since you'll most likely want to go fast all the time and with a short ratio gb, it'll be hell on FC.

Personally I think it's more economically viable to just get a 4G15. It's cheaper than the 4G91 these days and even though it's single cam, it doesn't mean it's weak. There's lesser parts to worry about and if correctly setup, it can be quite zippy. Have a look at the 4G1series thread somewhere in ZTH. There are a few monster 4G15s I've seen lurking around with over 110whp running on RON95.

Not that it's a lot, but my own 4G15 auto has 91whp and 109nm of torque. For an auto that's plenty. Dying to get a manual gb though. Wanna sell me yours?

if your budget less than 5k..then there's plenty budget performance parts for you to install and notice the power increased....u can consult iszo on this....furthermore vdo ecu is intelligent type so minor mods wouldn't hurt the tuning since the ecu would learn itself of the new mods...


but if got budget i would bot the engine...low pressure would be enough..since it was daily ride,torque improvement was the priority....
