Other cam info
Timing Events:
All of the above (except lifts ofcourse) can be calculated from teh timing events.

SR16VE

Intake Low: Opens at 0deg before TDC, Closes at 20deg After BDC
Intake High: Opens at 40deg before TDC, Closes at 60deg After BDC
Exhaust Low: Opens at 64deg before BDC, Closes at 0deg After TDC
Exhaust High: Opens at 70deg before BDC, Closes at 30deg After TDC

SR16VE-N1

Intake Low: Opens at 0deg before TDC, Closes at 40deg After BDC
Intake High: Opens at 40deg before TDC, Closes at 68deg After BDC
Exhaust Low: Opens at 64deg before BDC, Closes at 0deg After TDC
Exhaust High: Opens at 74deg before BDC, Closes at 34deg After TDC


Thanks to FastNX (http://www.sr20forum.com/member.php?u=1580) ,92nx2k (http://www.sr20forum.com/member.php?u=1083) and hpro123 (http://www.sr20forum.com/member.php?u=711) for the information

what lift is the duration being measured at?

But what does it all mean Basil!? Sorry I'm tring to find what overlap is and the searching is giving me a whole lot of info that is way over my head and explains nothing grrrrrrrr

anybody has the info about vet cams?

SR20VET
Intake cam
Low lobe: 8.0mm lift @ 212 duration
High lobe:11.0mm lift @ 248 duration

Exhaust cam
Low lobe: 11.3 mm lift @ 244 duration
High lobe: same

The VET has 13 degrees of overlap on the high-rpm-intake cam and single exhaust cam. There is no overlap with the SR20VET on the low-rpm-intake cam and single exhaust cam.

Is there a part number for the SR20VE (20V)? Is this a US buy or Japan only? G Spec does not list this cam. Hello, anyone home?

cam specs for the VET is abit Disappointing

What will work best for turbo? I have the stock sr20ve cams and they have less overlap than the 16 cams, but I get reversion when the cams switch? What cam would give the best spool characteristics and power within an 8k rev limit?

I am told to take out 10 degrees of overlap first to see how it does but I don't know much about cams and stuff. What would make a potent turbo cam as far as cam selection and cam timing?

This combo will have 60* overlap vs. the having 70* overlap with both 16ve cams.
The 60* overlap is with the 16ve intake cam centerline at 100*ATDC and the 20ve exhaust cam centerline at 114*BTDC.

While I'm at it, More VE camshaft overlap:
SR20VET - 13*
SR20VE - 48*
SR20VE 20V - 57*
SR16VE - 70*
SR16VE - N1 (v1?) - 78*


edit: added vet cams

Figured this would help this thread.

The 20V cam is from a European Primera SSS. How can we get it here?

VET cams may look a bit low on the duration side of things, but the lift is where it's at. They seem to look perfect for turbo. I guess I will find out.

can anyone help me
The SR20VE and SR16VE can be interchangeable cam shaft
