Hey Jei,

Sounds like a great Idea! I have an AP1 but I'll stop by and hang out.

jei: i'm definitely free at the end of may, so let's get a date set and i'll be there with the cam to document this to the s2ki world.

i know the change is very minor, but i assume that this shouldn't affect reliability should it?

anyone know how much a used set of cams would cost?

btw, i edited some typos in your post

This is awesome and I'll be in to check it out.



This will be added to my tiny list of mods for the motor.

The hard part will be trying to find an AP1 intake cam (unless you buy new obviously)!!! Those things are tough to come by.

I've been wondering about this for quite sometime now. I and I'm pretty sure a lot of you know this too. But in older hondas you were able to get a little bit more power when you swap ctr, itr, even gsr cams into any b-series. I want to know the outcome on this when you guys are done.

Interesting! What are the predicted gains?
I have a prediction...

4-5hp gains on the high end

Hey guys!

It's common knowledge that the AP1 Intake cam has a slight bit larger profile compared to the AP2 Intake cam. Here is a link off of Brian Crower's website that shows us US and Metric Lift specs but duration is measured at .050in of lift.http://briancrower.com/makes/honda/f20cf22c.shtml

With this said, the intake cam should produce more low and midrage torque and hp something we AP2'ers have, but could use more of.

I'd like to know how many people are interested. The people who are interested should start sourcing their ap1 intake cam. Once we get a head count, I'll prepare a brief write up with the tools you'll need to have handy.

Possible Questions:
Q: How long will a cam swap take?
A: If you follow our directions, the mechanically inclined will take about 30-45min. But I expect everyone to take about 1 to 1.5 hours for the first time.

Q: If we install cams, do we need valve springs?
A: Since we're installing am OEM AP1 cam, we don't need to change springs.

Q: Will you show us how to change valve springs?
A: No we won't have the time to do so.

Q: Will the AP1 cam make power without tuning?
A: We will determine this on my AP2. From the research that I've done, YES.

Q: Will you offer dyno tuning after we install the cams?
A: Not that day, I don't think we will have time for this. However I can accomodate you on a separate dyno day or by personal appointment at our discounted dyno day rate.

Q: Should I get any type of managment to tune this cam?
A: The profiles between the two cams are not too drastic so the common VAFC's, Emanage, EMS's or Kpro's can be used for tuning. I still anticipate that the engine will make power off the stock ECU map, just not optimal power.

Q: What about cam gears?
A: Only company that has them is Toda and they're a grip. If anyone has these and would like to use them in our demo, please PM me. We should be able to get more gains by advancing the intake cam gear. (Asura need you to chime in here. You mentioned you knew someone who might have a set)

Q: What are the predicted gains? (from Project22a)
A: I would estimate 5whp and 5-7wtq from 3k to 7k rpms without tuning. The cost of a used cam + 30min install seems like a good bang for buck mod. With tuning possibly more.

I'm happy to answer any of your questions. I thought it be cool to do something for the NorCal S2K community. Not asking for money or anything for this occasion.

We can definitely have everyone pitch in for lunch or something. I'm thinking Kinder's BBQ sandwiches or something.


Jeff, I expect you to be here with cam and tools in hand
Won't it take longer than a half hour just to let the car be cold to adjust valve lash?

Not trying to be an ass but 30-45 minutes sounds a little too short for a cam swap and valve adjustment
