rebuilt engine... you will not satisfy with the end results.

haha.  My experience with engine overhaul scared me away from doing it again. maybe the repair workmenship quality does counts in though.

btw i recently just bought 2 bottles of 3M fuel system cleaner, 2 can of seafoam, 1 can seafoam spray, and 1 bottle techron

so far my observation are:
- techron works for 1 half tank (car noticeable smoother, no jerk when aircon kicks in)
- seafoam does almost the same as techron, can feel car a bit more torquey
- 3M does feel less jerk when aircon kicks in, but performance remain the same

cost me quite some penny for them, though

Good day all sifus
What are the common cars with GDI, other than the VW ya? Thanks
