2007-2012 altima 2.5 JWT cams

one of the members on the "other" forum was finally able make this happen! this is the original email

Hi Rob,
I checked with our engineer who was involved with the JWT S1 camshaft development and here is what I found out we can offer.

$596.00 = JWT S1 camshaft for 2007+ QR25DE (requires use with JWT QR valve springs)

$224.00 = JWT HD QR25DE valve spring ($14.00 each x 16 quantity)

Note the factory valve springs in the 2007+ Altima QR25DE and Sentra SE-R Spec V are softer than the 2002-2006 QR25DE valve springs so they will not work with the JWT S1 camshaft profile. If you wanted to use the earlier 2002-2006 factory intake and exhaust springs (they are different part numbers), they could be used and put into the 2007+ QR25DE engines to then use the JWT S1 cams but the rev limit would be limited to 6,200 rpm which was what those earlier model QR25DE engines ran to. The JWT valve springs allow a rev limit as high as 7,200 rpm when using upgraded pistons, rods and JWT balance shaft removal kit. Since we do not make a balance shaft removal kit for the 2007+ QR25DE engines, that rev limiter should then be limited to 6,600 rpm.

if anyone is interested heres the full details. im still trying to get in touch with them to see dyno graphs & any vids available.

I'm pretty interested.... this is interesting. Wonder how a camming 2.5 would sound like when I start my car... lol

That is cool, and the pricing isn't too outrageous either.

If cams/springs/timing wasn't such a whore to work on I'd be all over this.
