Mostly depends on compression. They have a little lope but if your close to 10:1 you'll be cool.

With extra lift LS/B20 motors come alive. Anyone with cams in a LS will tell you this.

Would B18B cams also fit the B20Z?

How do the specs on these cams compare to the crower 403's and 404's?

I've got some grinds. These have 10.6mm Lift. (GSR hi lobe is 10.4).

I have a friend who grinds my cams for me. He has many years of experience grinding race cams for BMW, Nissan, and Lotus in addition to Honda auto and honda motorcyle. He's a good guy and use to work for Chrysler's performance division back in the 60's when Chrysler was the horsepower king.

Sorry no dyno sheets...yet.

For the medium grinds and up I use Crower blanks.

I think I saw on one of your post that you have the Crower cams. Crower makes the highest quality components I've seen. I am probably going to get their Eibach valve springs. Good ****.

don't buy crower. they suck for imports. their cams break in half and their retainers break. The valve springs don't stay stiff. Don't do it.

Non-Vtec, if you have some numbers in mind then I can try to hit those numbers with a custom grind. Remember though that gross lift and gross duration are only part of the specification. Ramp profiles are not easily specified by numbers.


B16A2pwr, did you know that Crower supplies the other domestic cam companies with cam blanks. But I agree that their cams are not as agressive as the other Japanese cams and don't perform like say Jun3..

what would be a good grind then for the b18b getting the most power possible without loosing streetability(vauge q i know but this is for a street car that i want to get the most power out of. ive heard that the 404's from crower can get to be a bit much for street use (i doubt i would mind a lopey idle) and your medium and big cams have a whole lot more duration than the crower's do. basically i was wonderin if you could get 180whp out of a b18 stock bore with a p+p head 11.5:1 cr and all the bolt ons (jdm 4-1 and 2.5" back intake and skunk2 mani)

If you are running 11.5 to 1 compression on a re-worked head I am assuming you are going to have springs and retainers so you can use the medium grind. Your Skunk2 manifold will allow you to run more aggressive cams without sacrificing idle as much as with a stock manifold.

This grind is real good and has been a road race favorite. I always hesitate to give hp estimates so I am not. At 11.8mm lift at 284 duration the cam is really going to "come on" from 4,000 rpm to 8,000rpm.

Also, I back my cams with a money back guarantee so if the cam doesn't work we can try another grind. Every motor is different and behaves differently so this helps enthusiast find the right cam.

yes i would have springs and retainers. i hate to ask for generic hp estemates but im basically looking to see how close this would be to an ls/vtec setup. i would rather build the non-vtec engine if possible but i dont want to waste my money since 180 hp is very feasible for a mild ls-vtec stup that was kinda my goal with the non-vtec. basically i was asking if your mild cam will make more power than the 404's. i was thinkin b16a pistons arp bolts balanced rotating assembly springs retainers (crower) skunk2 mani and mild p+p and _______ cam. 8k redline

Yes I can duplicate any grind exactly- I just need the cam. The machine that we use can make masters of any grind.

I thought you have a Crower cam already.
