My buddy says that if I want more out of my civic, that I should get a new camshaft. Is this true? I am going to get a CAI and a catback too. What do you guys recommend that I buy to increase the overall performance of the car? I don't a turbo or supercharger, that would be to much.

I see by your avatar you have an r18. I would say your buddy is kinda right. You can make power two ways. All motor (new cam, stroker kit, higher cr, NOS, etc) and Forced Induction (turbo, SC, little electric fan in the intake.....) As the R18 is a new motor I'm pretty sure there isn't a new cam out for it yet. It wouldn't hurt to spend some money freeing up the gas flow now your gonna need a new IHE later on anyway.

LOL I hope he was joking.

A cam is usually one of the BEST way's to improve the overall power of a motor (all RPM ranges are effected) where some mods just move the power band higher up the RPM range. The negative side effects can be: worse idle (think muscle car, womp womp womp, i had a high lift cam in my 3.8 wow nice difference), lowering overall milage, longevity of the motor if using an extremem cam (not likely in a civic i wouldn't think), usually the requirement of premium fuel.

I haven't done a cam in a Vtec motor before so i don't know exactly how well these react as my previous experience is on pushrod motors. Usually a cam was done later on after all the smaller mods are done.

I noticed that under "All Motor" you wrote NOS. Is NOS considered all motor?

nope. Nitrous is considered a power adder by race classifications.
for classes that can have two power adders one can be a turbo and NOS or SC and NOS, or turbo and SC... as examples. so no NOS is not a part of all motor.

true but a cam with slightly higher duration should be alright... nothing major.
if that's the case IMO its not wrth doing, u can get "Nothing major" results with generic bolt on mods and some easier stuff than a cam.

easier than a cam? a cam is not hard. it doesnt even require removing the head to install. and a cam for the si with basic fuel tune will give you the same numbers you see from the stage1 turbo and supercharger kits.. except a cam is around $1200-800 not $3k-4k. you can have an I/H/E with the hondata reflash and the IPS K2 cam all for $3000. add labor fees onto that if you dont do your own installs. basically, for a slightly cheaper price you can get the same power as forced induction with a much more reliable, more easily maintained setup.

It depends on what else you've done or are doing. 1 part alone won't make much of a difference; it's the combination of mods and a tune that brings it together that produces results. Ultimately the answer is yes - these things make a difference and can be reliable on a daily basis so long as they're properly installed and tuned.

K20 engines are already very well optimized....like the F22.

Getting N/A power with cams and a 2.0 block is a waste imho.
2.4, 2.6 liter bottoms can run larger Stage 3 & 4 cams that will put you near 300 whp on 91 octane, depending on your compression ratio....or over 300 whp on E85.
