does anyone know what a D16 SOCH with true Vtec.. im talking the 3 valves on each side.. I've heard this motor has a ton of potential but whats its base HP ?

dstheman

1988-1991 Power : 130 hp (96.9 kW, 132 ps) @ 6800 rpm; Torque : 106 ft·lbf (14.7 kg/m, 144 Nm) @ 5700 (JDM)

Deetz

He asked about "SOHC" not double. Also, the dohc is non vtec

To the OP, i don't really know! I had rumors (it's all i've heard) that there is a rare 1.6 vtec zc, something like 135hp ish....but keep in mind being it's a sohc, so not a lot of torque. Not my cup of tea

dstheman

oh okay yeah i didnt pay attention to that my bad for false info

MAjdm

yeah thats pretty much what i was expecting around 130-140 . but does anyone know how to tell if its got the true Vtec

D16z6 is about 120hp stock.

If its a ZC, its probably got like 130-140hp.

"88-91 Civic, CRX, Si, SOHC ZC/D16A6 1.6 4 $495"

I got this from Nippon Motors. It doesn't tell hp/tq numbers, but that is the year and model it came in. the ZC IS the D16A6.

"92-95 Civic, Del Sol, SOHC, 16 Valves, Non-VTEC ZC/D16A6 1.6 4 $495"

I would say the ZC is NON-Vtec. (D16A6 is non vtec if I am not mistaken.)

Of course, this comes from only 1 website and can only be taken 50/50, which is why I said "if I am not mistaken".

I would just use the D16Z6. I have one and I love it.

To know if an engine has vtec is super easy, it will have a vtec solenoid!!!

MAjdm

ahh ok but any way to tell if its the true 3 valve ? or 6 i should say

No such thing as a 6 valve head buddy. Not sure where you heard that from.

Meister vtec

yeah man where on earth did you get the 3 valve x2 setup,at first I was like 3 valves in total,damn thats like what benz uses,then you stated 3 valves per side and I was like whatt!

the only 3 in a d series I can come up with that infact is rare is the d16 3 phase vtec unit that came in +96 ek vti's= 130hp same figure as the zc 1.5 d15b vtec just with more displacement and the added 2 valve per cyclinder cycle(what the U.S vx's have) under 2200 rpm= much better low rpm performance and mileage.

MAjdm

i'm not 100% sure thats why im asking a buddy of mine who's been in the honda game for awhile briefly told me about it all i know there was a third valve for Vtec .. must have just been on the intake side.

Oh i see what you're trying to say. You're getting valves and cam lobes mixed up. BIG difference haha. A VTEC head will have 6 lobes per cylinder (B-series), or 3 lobes per cylinder (D-series).

lol so much misinformation.

You're talking about a 3 stage vtec SOHC.
http://en.wikipedia.org/wiki/3-stage_VTEC

They are very rare, but they have been imported into the US. Basically, lower rpms run in vtec-e lean burn mode, middle rpms run normally, no vtec, and high rpms run vtec like a normal y8/z6.

They are pretty cool engines, but a pain to tune from what I've heard. I've heard that the AEM EMS works with them.

The way you tell if you have one is to look for 2 vtec solenoids. They will look like what someone previous posted, only you'll have 2 of them. Like this:

ok thanks yeah im just trying to do a little research on them.. im picking up an EG hatch (building from the ground up) and was trying to figure out what motor to put in. b18b or j32 d16y im not sure yet so many options

Vindicator9000

There are gigantic differences between all three of those.

If you're going to stay N/A, go B18C1.

If you're going cheap turbo, go B18b.

If you're going *really* cheap turbo, go d16y8 or d16z6.

MAjdm

looking to do a mild build ... if i come across a B18C for a good price ill pick that up but so far is looking like the b18b is going in
