well some bad news today...
I was planning on throwing in scat rods and keeping the AEB pistions... Today when I started measuring the block to skirt clearence, i got about .004" which is out of spec by quite a bit... I am almost certain that this motor has been taken apart and heres why... (this motor has 126K on it) NO taper at all in the cylinders, cross hatching was perfect and i mean perfect, rod and main bearings were brand new looking, and lastly, the the oil pan had no thin film of sediment on it like every other motor I have ever taken apart...

So the question is, which brand and size and compression of pistions would YOU run... Also please offer me any first hand experience that you have had with over sized pistions... Good or bad... You can post up about things you've "heard" from a "friend" but Id really rather have first hand encounters as there is too much bull**** floating around... I appreciate your help guys

Where are you measuring the skirts?

IF you replace the pistons, I would be onclined to go with 81.5mm 225TT Pistons

What is the difference between the 81mm piston found in the Golf 4 and the one found in  the 225 TT  huh
