What end gap clearances do people run? As the figures given by je pistons seem very much on the high side. Ive put the rings in the bores and the gaps are on the smallest spec nissan gives. The cars going to run about 600hp.
Any help would be great as i REALLY dont want to rebuild it again because my gaps were to small.

17-18 thou on the top ring, 23 thou on the middle ring and the stock gapping on the oil ring which is ok provided its over 15 thou
this is how i did mine (je pistons)i was following T.F.S's guide to rebuilding which you can find on here http://www.gtr.co.uk/forum/upload/53670-rb26dett-removal-rebuild-refit-running-setting-up-guide.html

 

[T.F.S.]

lol, yes thats it

i thought the gapping advised were way too big as supplied by JE, lets remember now that you must times it by inch of bore!

if its too small (nissan std gap) the piston wil cease in the bore at full throttle

the Je rings that were supplied to me were too big out of the packet (uncut)on the middle ring which is why they are at 23thou (three thou over IIRC)....i was concerned about this but she leaksdown fine and compression is good

if i could i would go slightly smaller on the gapping by a thou or two, all IMO

I think ill go for the ones t.f.s used, 'street moderate/turbo nitrous' gaps given by je.
Cheers guys.:thumbsup:
