Hey guys, I'm performing an independent cam test (CTR, JUN 3, Toda B, Spoon, Skunk2) and I'm also collecting all the valve train info I can. If you have 93-2001 Helm Integra manual please look these up and post.

92-93 GSR spec (should be same as delsol's)
94-2001 GSR spec (I suspect these should be the same through the years)
98, 2000, 2001 ITR spec

In the Specifications chapter (probably chapter 3), under Cylinder Head/Valve Train there is a camshaft spec. These are for 95 del Sol B16A.

Cam lobe height
intake primary 33.088 (1.3027)
mid 36.267 (1.4278)
secondary 34.978 (1.3771)
exhaust primary 32.785 (1.2907)
mid 35.720 (1.4063)
secondary 34.691 (1.3658)

Also Valve Seat "stem installed height"
intake 37.465-37.935 (1.4750-1.4935)
exhaust 37.165-37.635 (1.4632-1.4817)

 

Hmm, nobody has ITR manual here? 98, 99 (Canadian), 00, 01 specs?

 

I'll get the ball rolling....

PS I emailed you awhile back on this info for the ITR primary and secondary lobe heights at g-speed and I guess you never replied because you don't have them either!!

These are ITR numbers right...


Thanks.

Thanks Tuan. The lower lob specs @ 1 mm is in the HyperRev mags, which I can't find mine lately, otherwise I'd replied... sorry.

Need the valve stem install height (which is the spring install height), not the valve guides. Thanks.

 

Yes, they are the itr numbers.
