i found out that my ep3 has vtec only on the exhaust side cam. i was wondering if i could find a set of cams that had vtec on both and use them? would it work? what kind of cams should i use to swap out to get the most power out of my dollar? can someone give me some insight?

 

I think just about everyone in here would have to say that if you're looking to go all-motor that you should just get a K20a2/K20a swap and call it a day since the K20a3 isn't worth building for all-motor purposes.

If you're looking for significant gains from the a3 motor i think most would recommend that you look into going turbo due to the lower compression. I would say go with the turbo and have it done professionally to save some head-aches, take it from me as i know about the headaches.

 

right, i realize that. but, the thing is that i want to do some internals first and throw a SC on there. got any other insights?

 

I know that on this thread someone had cams made but i dunno if they're going into production... never really kept on the thread.

thanks for the extra info. i read this thread earlier this morning. i never heard of raz cams before though. i've looked on jhpusa.com also for some cams. anything else?

You have Vtec only on the intake side. there is no exhaust vtec.

If you are looking to go with a supercharger, I have a stage I cam that is being produced for sc/turbo applications. the stage II cams are for n/a applications.

i was told by ?"srzracing"? that vtec is on the exhaust cam. but, yes, i am looking forward to throwing a sc on my car. do you know if i could use ctr cams on mine? would it work? please let me know more info by posting up or sending me a pm. thanks

srzracing = mike = my buddy.

I'll slap him later. He just got it backwards. there is NO vtec on the exhaust side. VTC & vtec are only on the intake cam on the a3 heads.

a2 cams will NOT work in a3 heads. The lobe spacing is different on the cam. That means the lobes will not sit centered on the rocker arms. The exhaust side won't even fit b/c the primary lobes hit the rockers.

Trust me, I wouldn't have gone through all the effort to make custom cams if there was an easier way.

 

so do you know where i could get a good set of cams for a good price. my main goal is to get the most hp out of some engine mods while building it to be sc ready, and throwin that on later. i'm new to the 01+ civics, so forgive me if i may seem ignorant. used to old school civics.

 

i say k24A2 BRO

 

i need to get those cams from ya leave me info or call at 770-294-7701

 

man guy, what the run around. you dont need a full engine swap. find you an rsx type s head and swap only the heads out. direct bolt on you might not even break a sweat. then go to todaracing.com and look at their engine kits...oh yeah youll need to reflash the ecu

Yup -- that's the way to do it without doing a whole motor.

The A3 does NOT have the low-speed and high-speed camshaft profiles like the A or A2 motors. It's a high-economy, low-emissions VTEC. You will not feel a kick in the pants at 5000 RPM.

If you do raz's/chunky's cams, understand that you'll probably sacrifice a bunch in the low end; they're made for high RPM pedal-to-the-metal driving, and that's where they seem to excel. In a way, they're like having only the "high cam" side of VTEC, but without being able to change to a "low cam" for lower RPM's.

If you want to keep the engine block in the car, either get those cams or do a head swap. No other company has come forward with cams for the A3 despite advertising "coming soon" for at least the past three years.

 

So how difficult is it to swap heads on the k20 with say a k20 from the rsx-s (is this the same as a k20a2?). What is a k20a1 (or is it not real)... sorry new guy here

K20a = Type R

 

yeah, but you see, the main thing is i don't want to do a head swap right now. i don't want to f*** up my warranty. plus, i've never had a new car. i'm just worried because i did a head swap on my 94 civic to make it a mini-me and i don't want to have to go through the same ****. i'm thinking of saving some money while doing my i/h/e and put some forged pistons in along with the sc. know what i mean?

Strictly speaking, it should not be true. However, the installation of aftermarket cams potentially affects any number of other items if it is done incorrectly, and the onus will be on the driver to show that the installation was done correctly and that it did not affect any other parts.

Even if you went up two levels to the district level service managers, you are going to have a problem unless you can get a really big name to testify for you.

When you start modifying your car to this extent, you have to face the fact that you have probably lost all recourse to the warranty.

Considering the trepidation you've expressed, I think it would probably be wise to just save up your money for a bigger improvement after your warranty is done.

The time spent saving the money might also cause you to change your mind about what it is you want to do, as you have the time to read more about possible modifications and as you drive the car more to make sure you really understand what it is about the car you want to change.

Sorry to be the wet blanket, but in your case I think that's wisest.

yeah, i'm going to have to argee with you there. i want to do minor things that i know won't f*** up my warranty and save while i wait it out. i'm sure that there will be other bigger improvements that i can do. thanks guys for all the insight.
