Vitara piston installation Info
There seems to be quite a bit of disagreement on which way vitara pistons should be faced.
After reading this post I decided to do some searching and this is what I came up with.
Vitara pistons should face the flywheel in a Honda motor, because the motors have the timing belt on the opposite side.
Which means if both motors where sitting next to each other with the exhaust side facing you.
VITARA T belt <-- left
Honda T belt --> right
The pistons will work both ways this is proven, but I believe this is the correct way to install the piston for maximum performance.
If anyone has any Info as to why they think Im wrong please do not hesitate to make your case known.
Post factual information, Not the usual well this is what my local autozone guy told me.
Pulled from a vitara workshop manual.

99% of the people are installing them backwards w/ the arrow facing the crank pully... when they should actually be facing the flywheel, because of the offset of the wristpin. .020 offset in the wrong direction will have those effects along w/ desent piston slap.
Just a thought.... about the issue ur experiencing
I measuered the "stock" Honda pistons, and wisecos that I installed... and the same wristpin offset was on the Viteras.... but the arrows were facing the Flywheel... So that's the way I installed them...since the Suzuki motors are transverse of Hondas.

The wrist pin is offset to one side just like oem honda pistons. If you match this pin offset with the oem pistons and put the larger valve reliefs on the intake side like they should be, the arrows point towards the flywheel.
Our shop has built about 20 vitara motors now - this is how it should be done.
Flywheel <-- <-- <-- <-- Timing belt
