Hi guys. My Alza has done 180K without any engine trouble. I gatal wanna overhaul engine. Do you think it makes a different? Full tank I am getting 450KM on average. Torque could be a bit better lah, IMO. What you guys think? How much does it cost? Any recommended workshops?
Also, what about ECU Chip? Worth it vs overhaul?
just personal thoughts.. if the engine is good, no point to overhaul engine. unless it has engine oil sludge, damaged piston ring etc.
450km average is okay liao.. all this depending on the traffic conditions as well as your right foot.
If need some extra 'power' at budget, you might try:
1. change the exhaust extractor.
2. possible injector (but if you hv change the extractor, you might not feel extra on this).
3. k&n filter (if you are a drive hard driver with mostly >3k rpm... in town drive, this might not help).
4. carbon cleaning. Some have mini camera to check the piston head are to see how bad it is before cleaning. or try find an injector/carbon cleaner that uses small amount at full tank over a period.. eg Redline Injector cleaner.
These are what I can think of...
Major upgrades.. turbo, supercharger, ecu... not tried out or research before, so can't comment much. personal thinking that alza engine may not built for these.
