technical camshaft query

**MassiEk4** · 06-02-2012 10:15 PM

Hi guys,

Long story short, I am left with one Buddyclub Spec III+ intake cam.
What I am wondering is that, can the Buddyclub Spec III+ intake cam be used with 2000 ITR exhaust cam????

at 1mm of lift.
Civic Type-R And Integra Type-R(Integra Type R 2000/01 Spec)
Int-243 dur. / 11.5mm lift
Exh-235 dur. / 10.5mm lift

Buddyclub Spec III+
Int-304 dur. / 11.59mm lift
Exh-294 dur. / 10,71mm lift

In my head it should work but with the exhaust cam retarded a little.
What do you guys think???

Thanks.

It'll work no problem,
Also your figures to compare are not quit right.
Your OEM figures are at 1mm lift & the BC figures are advertised.
The actual difference between the cams is not that great.
Moreover, the suggested combination would likely work better than using the pair of BC cams.
Re regarding ex cam, at little, but only a few deg.

Thank you for replying.

regardless of the combination, if you're running spec 3 cams of any description, i'd reccomend aftermarket valvesprings and retainers !

BC spec 3's are their entry level cam.
Std type r, they're a drop in.(Std springs)
Dunno why they call them 3's though.

Also true.
But I think it would be foolish not to upgrade springs and retainers or even valves when upgrading to after market cams; you would want to be able to rev higher than oem red line to make good hourse power, especialy if you are going all motor.

Because the general public thinks they're bigger so they buckle money on them instead of buying the good cams!

They're not necessary. The new camshaft might not need to rev out to 9,000 to make some kind of power, and even the OEM gear can take a little extra punishment.

Keep your valves OEM.

I fail to understand what you mean by "punishment" on the OEM cam gear?..

**dougie_504** · 08-02-2012 12:07 PM

You misunderstood me because I wasn't clear. By 'gear' I was just referring to the OEM valvetrain and other parts (IE rods/bolts) which need to be upgraded when considering certain builds.

That is, I was saying that the OEM springs/retainers can take a little more RPM/power than the OEM specifications/limits.

Wasn't referring to the cam gear itself.
