I was courius is this possible I have herd some people talk about it but still not sure if it will work ? If i put the d16 cam in my d15 motor what are the hp gains ? What new parts do i need to complete this swap ? is it worth it ?

 

why would a vtec cam work in a non vtec head? Think about it....the d16 vtec cams have seperate cam lobes for vtec. It would definantely not work.

 

Why wouldnt it ?

 

the d15b7 head isn't made to work with a cam that has seperate vtec lobes on it.

 

.

 

huh?

 

waste of time.. put on dc headers on the dx and you will feel a vtec kick in...

D15B7 cam:


D16Z6 Cam:


You tell me

 

all you guys are idiots.

Yes a d16 cam will fit.

A D16A6 cam that is.

But timing will be off a few degrees. The A6 cam is usually good for 5-7 whp with bolt ons, and an adjustable cam gear is needed.

A D16Z6 cam will not work

 

Why do you say that everyone is an idiot?

If I read correctly, the guy asked if a VTEC cam would work in his non VTEC head.
He then got an answer saying that no it wouldn't work and then you said the same thing that everyone else was saying.

You see the glass as half empty, i see it as half full.

I think he gave the guy some useful info on what will work with his setup, instead of just saying "IT WON'T WORK".

because Bauley is my bitch and can say things like that without hurting his feelings

 

yes d16a6 will work, but a d16z6 cam will definantely not work.

i'm new to engine tuning.. but aren't cam's in the head? and when you swap the d16z6 head, don't the d16z6 cam's come with? to be used with the d15b7 block?

correct me if i am wrong.</TD></TR></TABLE>

Ah ha. Probably the dumbest question i've ever heard if you've been in the honda scene for a while...but since you're new to engine tuning...i'll give you a break.

The D15B7 is a simple SOHC 16 valve design. Look at this cam here:


16 individual lobes, 1 for each of the valves...got it?

Now...the D16Z6 is also a SOHC 16 valve design, but it also has variable valve timing (the e-thugs around here call it VTEC). This allows the intake valves to operate at two different levels...look at the SOHC VTEC cam here:


1 lobe for each of the exhaust valves, and three lobes for each of the intake valves. The intake valves normally operate at the lower of the two levels (the lobes on the side) and at around 5000 RPM a solenoid pushes a pin through the rocker arms and locks them together...allowing the large middle lobe to operate the valves.



Explaination of SOHC VTEC: http://www.leecao.com/honda/vtec/sohcvtec.html

Now...what we do with a mini-me is take that entire head assembly as well as the ECU so that at 5000 RPM we can enjoy the extra surge of power at higher RPMs. VTEC can only be implemented with a complete swap of the head (due to different head castings) as well as the ECU...among other things. Read my mini-me writeup here: https://honda-tech.com/zerothread?id=554053

The D16Z6 allows for optimal power both in the low and high RPM bands...whereas with the D15B7 Non-Vtec model there is a cam that has to compromise and provide some power at both high and low levels.

Many race cars use the Non-VTEC engines because they can just get a cam that provides power at high RPMs (like the higher level of the D16Z6) because race motors dont operate at low RPMs.
