You should be able to make 180 hp with the medium grind.

I personally like straight LS/B20 set-ups and with cams they are monsters. Hotter cams make the difference and the simplicity makes them beautiful.

As for the medium grinds making more power, probably but I haven't tested them back to back on the same motor. You get more lift and duration with the medium grind so yes they should.

It's all about the lift on these Honda heads. The duration is there to allow you to you to get the lift.

Yes, I can duplicate the 404's profile. Just provide me a 62404 Intake cam and I will make you a copy of it on a new blank. I will send you back the original cam and the copy.

Cost will be $250 plus about $15 shipping.

My cost includes the cost of making a master for the profile. That's why this cost more than I would like.

Also at $250 I would be putting in some of my own money to get the copy done.

Why would you not just get the single from crower? It would have to cost more to buy a cam, then get it copied...you'd spend over 400 for 2 intake cams... Unless that is your plan...

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.
oh thank god i got the only good crower cams and springs in the whole world. i'm so lucky.
so have you had cams break on you? any first hand knowledge?

I have the Crower SOHC and DOHC Vtec blanks and I can see how if the final machining operations are not done properly that there spots on the cam that will crack and break.

If the machining is done properly they're fine.

Also it is my opinion if the grind can be put on stock cores that is this is the way to go since the stock cam is made from a higher quality core. Honda usually specifies the highest quality parts for their engines.

somthing with high lift and short duration/overlap

crower has a new turbo grind for the non-VTEC head with huge lift and short duration which should work great with turbo. 62402T

~INT / EX
235 / 235 Duration
.469 / .469 Lift

Whats you're take on these specs? These are the numbers for the new 62402T's. I've got a set on order. Crower has been on back order for them for a while tho. How well do you think these cams will work? I've got a Skunk2 mani, and run 10lbs of boost on a DRAG III kit just for reference.

The Crower tubo cam has almost the same duration as stock but with more lift so the shape of the torque curve will be the same just higher.

The difference in power from cams in a turbo engine is much more dramatic than in a NA motor.

the B20Z intake cam has .3 mm more lift.
So would that mean swapping in a B20Z intake cam into an almost otherwise stock B18B1 would make more power?

Would it even be noticeable or are we talking maybe 1-2hp at the very top?

You "hear" bad stuff? WTF. Dont spout misinformation just becuae that what you heard. Crower has had a bad batch or 2 just like every company does. People just continue to trump it up like Crower is some kinda of knock-off, cheapo company for that reason. Crower has been around for a very long time, their products are quality. Crower was one in the first US companies to offer aftermarket valvetrain support for the import scene. These people that complain about their cams exploding into 4 pieces prolly didn't install them right. Unless you torque the cam shaft journals down to the proper specs, and the cam will break. Last time I had my cams out I used a $200 Snap-on torque wrench that was accurate enough to properly set the 72 INCH/LBS. Thats 7 foot/lbs. Most torque wrenches aren't accurate below about 15 lbs....

Crower does make quality products, some of my friends run their springs and retainers with no problems, don't just read what people say on the net, talk to someone first hand.

Every company does make bad batches, remember a while back when someone posted a broken Jun3 cam? I agree though that it does come back to the install in most cases.

Yeah, what about those Skunk2 cams that had a "oil shedding" coating instead of a oil absorbent coating on there cams. Lots of new rocker arms were sent out of Hayward because of that along with discounted manifolds, coil-overs etc from Skunk.

lets not forget guys that the only cams that have ever broken were vtec ones. i have heard however of people having the vtec cams installed correctly and still breaking. but yes jun skunk2 are a couple of companys that have had broken cams. i like that oil shedding thing, kinda funny when you think about it.

as far as there other products there rods are awsome but expensive and all there other valvetrain is top notch.

I've got a Crower valvetrain sittin in my bedroom. Just waitin on my damn 62402T's. I felt the difference between the stock springs and the Dual Crowers. All I can say is man, they feel almost twice as strong.

So the bigger lift will raise the torque curve a bit then huh? Great I was already planning on upping the red-lin from 7k to 8K after I got the valve train and cams in. Glad I installed the GS-R block girdle and ARP rod bolts . My car is gonna be evil

Raise the torque meaning that for each rpm, torque(power) will be higher not just the peak numbers.
