Is this vtec normal?

[GSi_PSi]

internally stock b16a doesnt have a louder crossover than internally stock b18cR, changing to more aggresive camshafts, bigger throttle body and intake manifold will make your vtec engagement
more pronounced

B18 is a 1.8 litre, B16 is a 1.6 litre. As said above you wont usually hear the VTEC crossover as much in a B18 as you will in a B16 depending on modifications due the B18 having more power down low and therefore it has a more linear power band (which basically means when you look at it on a graph the power rises more evenly in a curve), where as the B16 has less power down low and so when VTEC kicks in it there is a large jump in it's power band and so it sounds louder.

Before a tune my BB6 stock crossover was noticable in a 2nd gear pull....However after at tune it wasn't.

After tune acceleration video clips.

Look at the power band, thats what i was talking about. Because of your mods and the tune, you've got more mid range power out of the engine before vtec kicks in, and so there is a smoother crossover when it does. Different engine though, but the same concept

the question is, does the OP have a stock ecu or is it tuned? Ask mwaku for more details cause I think that's his old car...I remember seeing pics of the mugen intake and stuff at JDMyard....the OP also needs to learn the basics such as checking oil level... lol

If it's not tuned then it shouldn't have a power curve as straight as mine so the VTEC engagement should be noticable.

every motor is different, ive found vtec is loud when the temperature is cold and its softer when its hotter

Not so sure about louder when cold in my experience, but I agree it's quieter when hot so by comparison yes.

True, OP certainly does need to learn a bit about the car, or about cars in general lol

Agreed

No offence intended but if you don't know how to check the oil in your engine, or even what engine you have, then I think the volume of your VTEC crossover should be the last thing you address.

+1.
If you want a louder crossover if you like i can swap you my 93 b16 civic for your ITR

[davidvtec]

No point discussing this thread if OP doesnt know anything about checking his own oil lol

[Zilli]

ok... you have a problem mate... there is no cutover. a B18c7 will have a noticable swapover from low to high cam at about 5700... there should be a chanGe in engine note, and there isn't.

Now, you either have an oil pressure problem, check your oil level (although if it was low enough to affect high cam engagement you'd probably seen your engine oil light)... try it anyway. Look in your manual to see how to check, otherwise the dipstick is found in the front of the engine near the headers, pull that stick out, give it a wipe down, then put it back in and take our. There are two lines, your oil level should read between those lines, if it isnt, go and get some appropriate oil, and top it up. The amount of oil between the two lines is 1 litre for your information.

The next question is, was that video recorded when the engine was at operating temperature? (ie. the water temp needle is as just under halfway?). If it was, then you need to check your VTEC Solenoid.

Now, given your inexperience with vehicle maintenance, i recommend you take it to a mechanic and explain the issue you are having. A specialised Honda mechnic like Hanny's etc would be your best bet.

In the meantime, take some time to learn about your car and cars in general, best way to do it is read, and try.

In the meantime, this is going to be a second thread of yours that has gone to shit, and unfortunately it's not your fault. I am leaving this open, but will be viewing it over the next 24 hours waiting for your response. anyone who contributes rubbish here will get an instant infraction.

Stay on topic, be helpful, or piss off somewhere else... first and final warning
