I have just an AEM CAI on my GSR and and I can hear a difference in sound over stock when VTEC kicks in and it gets much louder at 6000 RPM plus

 

i know i havent heard any other vtecs's that sound like an si. i wonder what type-r's sound like i would love to hear a type-r with an intake

 

The R stock sounded great. I added the Icebox (not the short ram with it yet) and it WAILS.

The reason why the R is louder (other than soundproofing not being there) is the single runner intake manifold. VTEC kicks at 5700 or 5900, depending on throttle position. It's VERY obvious. It actually makes something rattle after the icebox.

The GSRs, you only really hear it after the secondaries open up. Stock, at least.

 

Hey Turbonium try to reset the ECU and disconnect the Neg batt cable and leave it for about 5-10 min and let it sit. Before you do that if you have a stock stereo make sure you have the code for it. That can be a quick fix. Instead of spending the money and having it done by a Mech and get charged $60 or more to check it. I was having a similar problem. So check the oil and disconnect the Neg batt terminal. Let me know how it went.

 

A Civic SI with intake is going to sound louder than a GS-R with Intake.

As for the Type-R with intake my friend has one with AEM CAI, and thats all he has, and one quite night we were pumping gas in our cars, he finished earlier than me and went home, his place is 1.5 miles from the gas station and i heard him go all the way from the gas station to his house.

 

will do, and listen to the kik in around 6,000 rpm. i mean i hear the vtec now its just that my exhaust, cat and CAI doesn't distinguish much sound like it should. my friend that had a 92-93 gsr said he had basics like intake/exhaust and says that his vtec kiks in so much louder when he drove my car. it litterally screams compared to mine

 

Dual runners. You'll hear it when the secondary runners open up.

 

I know the dual-runner intake manifold is power-robbing (or so everyone says:dunno, but damn... I love telling people to listen for the little "pop" it makes...

vvvvrrrrrrrrrrr*pop*rrrWHRRRRRRRR

Actually... talking about VTEC has made me want to get iff my lazy ass and take a spin lata

 

another problem think could b your v-tec silonoid try replacing that

 

my car has only 35k on it so i dont think replacement is necessarry, but i was thinking of gettin an intake manifold..
