Im using these pistons on my sisters 7mgte supra build and the machine shop was asking what the clearences are for theses 40 over pistons piston to wall clearence. Does any one know what the clearance would be? I Called Aarron and he thought they were the same as with stock pistons but still not sure.


TSRM shows stock being .07mm to .09mm for 7mgte but my machinest was conserned the NPR's may call for different clearences.

I did search but did not come up with any solid numbers.

If you know what its suppose to be please post asap, the machine shops waiting on me to call back. Thanks!

i cant find a decent awnser either. bes bet is try to contact NPR and ask. but as NPR are just cast replacment pistons, id assume specs would be close to stock.
