Hai guys.

im currently running one 4G18 with adjustable pulley (1.5 degrees up), Sard fuel regulator, 4-2-1 aluminum piping. with the current setup im getting a top of 220km/k. What i want to ask is this, any more mods can be done to improve it?..ive heard about changing a bigger fuel pump.any suggestions?

by the way, my rims are 15"..if i change to 16" will it effect the performance of the car?..im talking about japanese rims not imitations.do advise.

thank guys.

install piggyback ecu like e-manage / afc neo or other n change to stage 2 high cam if u want! no need change ur fuel pump if u not do any big modification!

if stock saiz is 205-50-15 change to 205-45-16 is ok! not change large saiz like 215/225-45-16 u will b lose power a bit or performance
