do you use uprated springs for the sr16ve / sr20ve p12 (20v) cams?

is the titanium retainers enough?

springs get you 95% of the work done while titanium retainers do the remaining 5%. So retainers are just a small benifit

I have springs and retainers. I am hoping the 20V cams will be safe to 9k with the 6262 I plan on having that as my peak RPM.

I wouldn't trust SR16 cams at 9k on a turbo motor. 8500rpm max on that one. They may hold, but it isn't worth the risk imo.

I am going to try the 6262 on the 20V cams at their current settings. Then I am going to adjust the cam timing per Miko's suggestions and see what happens.

Can't wait to see if torque holds flat out to redline. Should make a hell of a lot more power, if it just holds flat. After all, 275wtq at 8000rpm is 418whp. Would be nice to hit that on 14-16psi!

my stock vz-r (sr16) reved save to 8k. and I think that some 500rpm will not hirt even without the uprated springs. the spr-h1022d-ve supertech springs are the stiffest (130 lbs open vs 100(spr-2035-2022) 90 80(H22) ,. but is it the best?

I would think the 20V cams would work to at least 9k with the springs and retainers I have. The 130lb for big revs like 10k+ iirc.

But I know from local experience that the stock 2.0 cams with the H22 springs with stock retainers may throw shims if revved over 8500rpm. Needs a bit of a stiffer spring.

I read that the n1 springs are softer for the higher lift.
If the H22 uprated springs are enough for the 9000rpm with the sr16ve cams - why do I have to make excessive load to the valvetrain?
or I repeat : the stiffer = safer and more efficient, no tower leaks?

Stiffer means you can run a lot of boost without the valves bouncing back open. The N1 springs are softer because the cams have such a smooth profile.

9000rpm on H22 with the Sr16 cams should be doable. But I wouldn't recommend it with the 20V cams. 20V cams may need something stiffer. I haven't had issues running 8800rpm right now with the supertech s/r. Hopefully I don't have issues in the future.
