So I'm looking at importperformanceparts.com and I see what looks like a rebuild kit for my tracker.  So my question is:  

If you go with the oversize 85mm pistons , and you choose the hold onto your nutsack 11:1 compression ratio pistons, rings, etc....what kind of performance improvement should we be looking at?

Also...I've been looking at Suzisport's ECU re-programmer.  Has anybody tried it?  I've seen lots of similar products for regular american trucks, and the performance figures a reprogrammer can provide are astounding (especially on a diesel).  Anybody have an experience with this product?

moter go boomboom after not much milage. yeah good luck with that one.

unfortunately like myself
the 2.0 litre seems to work very hard

I think personally cause it's cam'd for low torque rpm
but it definately has enough power at 3700 rpm and up

I don't think it's worth while to get minimal power out of a engine not designed to be performance/high reving orentiated

yea if your going mud running and can get some 100ll from the airport but if you want power why not put a 6 init
