I've been working on a h2b set up for a while stock h23a header intake exaust made 207hp @170tq with a ls tranny I'm doing some up grades as we speak going e85 ported intake manny 3in intake and exaust gst trans and lighter shell my question is im.looking to upgrade cams everyone tells me go pro1 cams my question what's people's experience with crower stage 2 cams pros and cons any imput in appreciated

 

I have a H22A4 in a '95 Civic Coupe, I have used Crower camshafts in it since 2005 and have had great success with them. I currently run a set of 63423P's making 244 wheel HP on pump gas. They are affordable, reliable and make power.

 

Is that a stock motor our built bottem end car if u don't mind me asking

 

Do you have graph or video? Stock block?

 

It is not a stock bottom end... Mahle Gold dome top pistons, Crower MaxLite billet rods, balanced rotating assembly. Balance shafts still function. Head work includes cc'd chambers, valve de-shrouding, bowl work and gasket matching. Crower dual valve springs and Ti retainers with modified rocker arms acting on Ferrea Comp Plus valves round out the head mods. Induction includes a custom shortened and ported Skunk2 Pro Series I/M, Alpha 66mm T/B, Deatschwerks 600cc injectors and a custom short ram intake tube with a cool air barrier. Exhaust chores are handled by a SSR 4-2-1 stepped header and a Thermal Cat-back exhaust.

Dyno numbers were measured on a DynoJet 224 with STD Correction and Smoothing at 5.

 

Ah nice. You have vids? What torque you make?

 

No vids... I don't own a smart phone !!! I don't want to lie about the torque... I want to say it was in the low 170's (like 172 or 174 ft/lbs) and occurred around 6500 RPM. I do remember that I in fact did lose a bit of power in the mid-range compared to the previous set up which included the stock H22 Intake manifold with throttle controlled butterflies, stock T/B and Skunk2 PRO 2's (229 HP/167 TQ), and that loss is directly related to the intake manifold change and I "over cammed" the engine. She does like it up top though...

 

Ah ok then nice. So the cam you have is bigger than people would think huh?

 

Yeah, it is pretty big. Lift on the Intake side is .514"... it required "clearancing" the underside of the oil bars to allow the VTEC lobes to swing past without making contact.

 

So you have the 63423p cams?

 

Yessir...

 

Ok that's why you lost midrange. Yep, tells ya over and over (or me over and over ) that you can't judge and compare cams by their numbers alone. The cams you have are a 268 @ .050 with 12.9mm lift.
