budget? give exact figures n what ur target is...what u expect toget out of ur mods


be more specific with ur questions

Madman is right.

So many mods can be done.

Put cap ayam filter is mod. Change plug is mod. Change plug wire is oso mod. Put turbo is oso mod. Put trumpet oso mod.

Then what is the mod purpose?

Save fuel? Power crazy? Good pickup? Etc....

change mufler first
then air filter
then plug cable
n so on...

Ermm if for track use? I don't want bot on turbo... Pointless to bolt on turbo on a n/a car... Waste time waste gas...
Mega power recommendations pls...

The only way for 4G91 is to BOT if want to meet ur requirement

If u want to gain some additional house power for daily driving fun, just go for those basic up upgrade such intake / outlet and firing system.
Lightweight ur car is the most significantly u can feel it.

For na car, change to racing bearing, balancing crankshaft , balancing fly wheel, it can make u easy to rev to high revolution , change to racing cam and add a adjuster cam pulley, put a emanage inside and tuned it , will make a lot of fun, gear ratio can modified abit .
