Question: Swap a D16Y8 to D15B (D15z7)
Hello my friends, i'm from Brazil and i have a Civic 2000 EX Automatic. I am very interested in swapping the engine of my car for a D15B VTEC with 3-stage. Here in my country no there is this model of engine and that is why I need your help. So, what is needed to transform one EX into an VI-RS original? And where can I get import these parts?
I would be grateful for the help.

no its not mine came on a d15b it had two v tec sylinoids...yup butchered that. they are very very slow my d16z6 would smoke the **** out of one. The guy that sold me the motor said it was just as fast as a d16 and boy was he wrong. One plus side to the motor is that when the v tec hits it is very loud and a **** load stronger than stock...but in the end its still a d15=slow

The Vi-RS has disc brakes in the rear? The suspension is the same as the EX?
The finishing parts I want to find on the internet and buy them or ask a friend of mine who lives in Japan to buy them for me.
Tnx again.

I found several engines D15B with 2 VTEC solenoids sale on Ebay, but I'm afraid that is not the engine of the Civic Vi-RS...

I had the stock tranny from my ej8, I just blew my motor and he sold me that. On the block it said d15b...I think that its just to swich over from normal to like a gas saving valve then the other solenoid is to switch over to the more powerfull vtec. To get that you haft to get the ecu...witch is hard to find from what i herd and run a extra wire from the ecu to the other.

I found one D15B selling one ebay, Is equal to that used in the Vi-RS?

I beleive so but for it to be the true vi-rs you haft to get the harness and ecu cause it has diff sensors than the usdm version. Thats why they used my stock intake manifold and dizzy. All it does is help with gas...just if you need to save gas keep it out of vtec

Re: Question: Swap a D16Y8 to D15B (D15z7)
To use that engine you must use the 99-00 P2J ECU. This should be pretty easy to find if you're keeping the automatic. If you convert to manual though it is near impossible to find a manual P2J ECU.
The only thing you have to do to install that engine is run one more VTEC wire. The double-VTEC solenoid has two wires, one is red(/white?), the other is green/yellow.
The red wire needs to be ran from the red VTEC solenoid wire to pin A21 on the ECU. You already have the green/yellow wire.
I think you should be good to go after doing that.
Though you might need a 5-wire O2 sensor, i'm not sure. You'll have to check into that.

Let me get this straight, then the block D16Y8 is compatible with the head of the D15B (d15Z7), if only I use the ECU P2J-J62 (I will remove the automatic 4-speed and use the CVT) instead of P2P. The VTEC another wire is needed even using the ECU P2J?
And the intake and exhaust manifold? I use such parts of the engine D15B or D16?
I found a message saying that:
"The" D15B "I am referring to comes from the OBD2 (1996-1999), EK3, Civic VTi Civic Ferio Vi. With the exception of the dual VTEC solenoids, it's Identical to the D16Y5, or the D16Y8 but with EGR. "
It is necessary to use the EGR? It is located in that part of the engine?

Re: Question: Swap a D16Y8 to D15B (D15z7)
ah, there might be some emissions stuff like EGR that you have to do. I think yea, the EGR is by the intake manifold.
The wire is needed because your current engine harness doesn't have the wire in it.

Re: Question: Swap a D16Y8 to D15B (D15z7)
- Intake manifold of D15B
- ECU P2J of J62-D15B
- Head of D15B
- Wire of engine D15B
- CVT type m4va
Anything else I've missed?
PS: I want to put all the internal and external finishes of the Civic Vi-RS, including the instrument panel, would be interesting to just buy a complete wiring?

But the config to perfect engine swap is right? I intend to arrange for the purchase of such parts as soon as possible ... hehehehe

Re: Question: Swap a D16Y8 to D15B (D15z7)
Well, putting the D15B head on a D16Y8 makes me worry about a couple things...
1. cam-crank timing. It may be fine but i'm not really sure. I am leaning more towards it being fine though than it becoming a problem for you.
2. valve-piston clearance. Once again, I think it's fine, but i'm not 100% sure.
I think you have all the parts listed. Don't forget the head gasket. I'm also not sure if the D16Y8 head bolts will work.

Re: Question: Swap a D16Y8 to D15B (D15z7)
If you don't know what either of those are this probably isn't something you should be doing.
When you start mismatching block to head, you can end up with problems.
Crank-Cam timing is the relationship between the timing of the head and the timing of the block. On most applications, you want the head and block both at TDC (top dead center) at the same time.
Because certain heads have different heights and certain blocks have different deck heights, certain combinations of block and head cause you to end up with a different distance between the crank and cam than the engine the head was originally from has. This causes the crank and cam to be out of sync with one another, meaning the timing is off.
Sometimes this can mean that you need to use a different length timing belt, and/or advance/retard the cam timing so that the head is at TDC when the block is at TDC.
valve-piston clearance is simply the distance between the valve and piston when the piston is at the top of its stroke. If you do not have clearance, the piston will hit the valve, which can/will cause you to eventually have bent valves at the very least, and possibly a hole in the top of the piston. If you have even LESS than no clearance, meaning the paths of the valve and piston intersect one another, the piston will hit the valve hard and the valve will bend and/or the piston will break.
Think of the piston as a semi truck and the valves as a bridge. If the semi truck is too tall to drive underneath the bridge, it will hit it.

Re: Question: Swap a D16Y8 to D15B (D15z7)
I know this is a 13 year old thread but I was just wondering if it’s possible to just swap from a dual vtec solenoid to a single? I have a d15z7 head and from what I can tell everything internally on the head is the same as a y8 head besides the vtec solenoid being a dual solenoid instead of a solo. I was just wondering if I can just put a y8 solenoid on my z7 head or will it cause problems? If I can’t do that then do I just run one green wire and leave the other one off? Thanks for the help
