Cams for a 13.8:1 CR 2000cc B18C race engine
What would you recommend?
We have Pro2s now. Was considering just upgrading to Pro3s, but personally I think rocket M25 would do better.
Or maybe something custom? If so, who would you recommend?
Also, who would you contact regarding buying Rocket spec cams? (feel free to conact me if you are a dealer)
PM or email if you have used Pro3s or something else

Darton MID sleeves, bored to 85mm.
Arias two-ring custom pistons (ceramic and moly coating).
Bisimoto custom long rods.
B16A2 head with full sqish pad, and ported locally.
Skunk2 pro2 cams, skunk2 pro cam gears, skunk2 pro valvesprings, skunk2 pro retainers (everything here has been through two seasons of rallycross racing).
OEM type-r intake valves, OEM b16 exhaust valves
Jenvey ITB
Cometic head gasket (85mm)

Thanks alot for the tips.
If it was my own engine I would love to test some custom/extreme stuff from ALL MOTOR, but since it is a customers engine I will most likely go for the safe route.
I also considered Bisimoto level X, bet they will produce massive top end power, but in rallycross its great to have that low end power you get with the skunk2 pro series or similar (level X is a "vtec killer").

When I switched from Pro-2's to Pro-3's on my 2.0L, I made more power everywhere.
You have more compression and better induction. I'd imagine Pro-3's would be a great upgrade.

if its been tru 2 seasons u might wanna freshen up the block with new bearings..and new valvetrain for the head..at least check for spring preassure...
cibao2ner: All parts of the engine will be inspected during the winter.
ALL MOTOR: I do clay all my motors, and all clearances will be checked with the new cams as well. (see my facebook page for proof).
92TypeR: Thanks alot
Wish I could find some cheap Pro3s? Would be great to be able to test some Reapers or Deamons against the Pro3s on this engine

It's not all about dyno numbers and the like. i don't understand why people think that American companies can't make great equipment. Crower has been around since 1955, they obviously know what they are doing. I think the reason Crower or Comp Cams aren't used more often is because ignorant people follow what everybody else is doing. I'm not saying that everybody else is wrong, I'm saying it is possible to make power with a new setup instead of a cookie cutter b-series build. Crower wouldn't put the product on the market if it didn't work.
And the correct way to state your question would have been 'Really? Where ARE all of the DYNOS on engines using their cams?'

I never said dynos weren't valuable. Crower is just less common in the import world, so you won't find as many dyno charts for engines using Crower cams. The other thing people (not necessarily you guys) over emphasize is peak power, you need to judge a part by its power band, not the peak numbers.
Crower is less common in the import world because they simply don't perform as well as other available choices. That's just how it is. They're background is in domestics and that's where they seem to focus their energy, nothing wrong with that. You're making general statements and then revoking them by saying "not us", well if that's the case, you're preaching to the wrong crowd. I can tell you that if I could make more power overall, not just peak, with Crower cams, I would have been running them a long time ago. That's how Crower is judged by most people and that's why they rank where they do in the import world.

What gearbox setup is this car using ?
And what is there USABLE rpm range that they use ?
What weight is the car ?
What size are the Jenvey's ?

This season he is running a stock b16a2 gearbox with a custom final drive and a LSD (plate) from six time european rallycross champion Martin Schanche. He says It works alot better then both the type R and the quaife LSD.
Traction is often a issue (many corners are whet gravel, 3500-4000rpm 2.gear mid corner), so a strong and smooth running engine with a extremely wide powerband i preferred. The Pro2's was great in that way, but lacking some top end power.
Don't know the weight, probably around 950kg (2100lbs)?
Don't know the size either, think they where bought used.
