    I'm looking up Ring end gap on Alldata and its giving me these values.
    My current measurements on 1st ring are .406mm (.016in)
    2nd ring is coming in at .559 (.022in)
    Is that too much on the tight side?
    Plans for the car are to stay on factory T25.
    I'm using factory replacement pistons.

    You are actually on loose side if comparing with the OEM spec but it would probably be fine, better than too tight.

    Thank you for the reply. I was under the impression my alldata values were incorrect as everyone on here is running loose. I couldn’t find anyone mentioning the factory specs. But then again no one on here is keeping their vehicle factory haha.

    Those are fine for a low boost low cylinder pressure spec. Don't be worried about them. I opened up the factory gaps on a semi-stock build and feel great about it.
    Your good! :thumb:
