My understanding is that a neo's recommended lash is the same as a rb26, so:

Intake side
Cold (20 C +/- 5) 0.45 mm +/- 0.03 mm
(68F +/- 9) 0.018 in +/- 0.001 in

Exhaust side
Cold (20 C +/- 5) 0.38 mm +/- 0.03 mm
(68F +/- 9) 0.015 in +/- 0.001


Room temperature compensation
0 +/- 5 C +0.02 mm
32 +/- 9 F + 0.0008 in

10 +/- 5C + 0.01mm
50 +/- 9 F + 0.0004 in

20 +/- 5C 0
68 +/- 9 F 0

30 +/- 5C -0.01 mm
86 +/- 9 F - 0.0004 in

^^^ I do believe that is incorrect, I read they are different (some said opposite, I suppose they are semi-close enough to say the #'s are reversed)

Also this owner http://www.skylinesaustralia.com/forums ... clearance/ measured his, converted from IN to MM it matches my findings.
