sorry for the late reply bro... i just got my car last thursday lah... hehehe....
ok i have changed a few things lah in the eng...(i m running SVT 20v eng)
1. AE111 forged pistons + bearings
2. crankshatf
3. conrods + conrod bearings
4. TRD metal gasket
5. Sard fuel regulator
6. and overhaul, port polish and balanced.
When accelerate, the car eng is very light and very responsive(i can only rev till 4k RPM lah. gotta wait till 1k km and service 1st). As a lots of ppl says, after u have done all this things especailly everhaul, port polish and balanced, ur car's fuel consumption will be very high and the power oso so so only. Things will starts to change lah after u have service ur car for the 1st 1k km. But as for mine, i can feel the power has been improved and the fuel consumption is good.
B4 everhaul, port polish and balance my car's fuel consumption is RM53 --> 380km but now i can go RM53--> 440km. A great improvement. My mech says after i have service the car, it can go higher and the power will improve a lot... (dunno how true it is lah... :) ).
