I have a 2.0L motor sitting around that was water siexed (rusted) ao this weekend I pulled it apart.
Needs new pistons and cylinders so I was looking at this big bore (no machining needed) kit. Anyone have experience with this particular kit? http://aapistons.com/index.php?main_page=p...;products_id=58 |

So, being the cheap bastard I am I bought a set of AA off of ebay.
Overall I am extremely satisfied with these parts. I built the engine over the winter and have about 3200 miles on it so far this summer. Broke the engine in hard, bringing the car imediately to the redline several times shrotly after the 20 minute cam break in period. Oil consumption has been almost nothing. I know some folks have had a problem with the rings seating but for me it wasn't an issue. Now the things that you need to look out for. 1) Rings had .002 of gap when I measured. Not really a big deal because we should be checking and setting anyway. 2) Says pistons are balanced within 1 gram, I found this was not the case, more like 4 grams. Was able to match the heaviest rod with the lightest piston and only remove a small amout of material to get where I wanted it. 3) Height of cylinder from shoulder to top mating surface varies a bit. There was about .004 variation. I was able to swap each cylinder around and find the best combo. So far no leakage from either bank of cylinders. I would suspect you would find similar issues with any set you bought but for the price I would highly recommend based on my experience. -Rob |

Thanks Rob, Real world info. What did you end up setting your ring end gap to.
Rich Towle told me he ball parked his pistons on his scale then used the high end scale down at the post office to fine tune his pistons. That's cool!
