i have pretty good amout of mods on my 97 civic ex...i have a b&m fuel regulater and i have a cold air intake and catback exhaust and unorthadox racing pulley and i race a bone stock civic and it kept up with me a car length. but im having exhaust leaks i don't know if you lose power but i don't think my vtec is kicking in

 

Can you rev to redline?

The vtec on the EX engine is designed for fuel economy not high end performance. It should be a smooth transition when it switches to the second cam profile. If you look at dyno's, there is often a slight drop in power when vtec engages.

 

on my friends ex he could never hear his vtec kick in cause its so quiet...you barely hear the cam switch over...its very quiet...also i think exhaust leaks do affect performance...im not too sure on that though

 

The VTEC crossover is weak on the EX.......... doesn't feel like anything on my friends 99 EX

 

it was the HX that was designed for fuel economy.

vtec on the y8 is not a sudden kick in power. its not in any vtec motor. its a smooth transition. its just that the d series is not your power breathing monster. simple bolt-ons arent gonna make you fast. youll get a lil better performance but thats about it. the easiest way to get somin out of these motors is forced induction.

 

That's weird. I have the same problem...

I can't feel VTEC in my Integra LS? Anyone know the prolem?

 

Have you checked your main capacitor? Maybe your muffler fluid is low?

 

Uh, LS's aren't VTEC... I hope you were kidding.

 

you wont feel vtec in a civic EX unless you do a cam upgrade.

 

haha nice....

 

Damn no wonder I have the same problem with mine also? Thats weird my vtec solenoid
