Lets get started!

The D16A6 had 265k miles on it when it decided to bend a valve(actually 3 valves). So I decided to take a big step and perform my first engine swap with Honda's. Installing a D16Z6.


Got the header off and a few other little things

Got the axles and shift linkage out:








Comments are welcome. BTW this is my first engine swap... ever, and I did it by myself(with the help of my mom on the hoist half the time ), so if I did something stupid.. o well.....

Update- 6/16
I cleaned everything up(engine bay and engine): before and after pics:










Tomorrow I get the new engine (d16z6 with 11.5:1 CR).

Last edited: can use water where you live...we are still on restriction.

looks good.. you better update this mang..

Like I said, I'll be picking the new motor up tomorrow night, so I'lll have an update in the next couple days(plan on installing it Sunday.), so keep your eyes out.

yeah, I have a friend in Mesquite. He said there was some problems, evidently thats one of them... (just for you I just walked out and watered my lawn for 1hr.......:p )

A z6 mini-me for now. I can't remember what all he's done to it(a friend of mine here in town), but I know it's got 1.5l pistons and probably a y8 hg that bumps up the CR.

I eventually plan on throwing a small turbo on a single cam vtec motor for a daily driver. not particularly this motor, but he's selling it with a lot of stuff for real cheap, so i can't really pass it up.

Updated ALL the pictures. It's all resized and in order. And got rid of the walkthrough type stuff, it's all there, just need to use your head as to what I did...

No engine tonight. I'll pick it up tomorrow at lunchtime.
Update tomorrow night.

Update 6/18







I have one question, though guys..
Whats this plug? It's got two wires on it, and it's not on my z6...(harness is off a6)


? If I remember right(check tomorrow evening after work), it's not something I can tak off of the a6 head and put onto the z6... i'll get pics tomorrow, but it's about 5in behind the alternator plugs.

Thanks fellas
dude sell me those ac lines!!!!!!!!! Its me Abel from Tally. I'd like a full view pic of your car if you dont mind. I think i've seen it around town
lol your still looking for a/c lines, you shoud have gotten mine when you had the chance.

anyways I would have to see a better picture of the plug to help out
^ I'll get a better one tomorrow after work.

it's the only plug right under the IM/plenum...
rectangular with two plugs.
gotta go to sleep, but expect a new pic tomorrow evening.

possiblly the fan switch plug. On the A6, its behind the engine while on the z6 its on the thermosat housing.
Got the new picture, so here you go.


And can someone let me know which wires control what for my vtec? i'm assuming it's the right coloring of wires.


the grey plug with the green wire goes to the vtec, not sure about the other plugs, they dont look famillar to me. the plug on the back I think it for the fan switch.
The big long one(in back right) is the only wierd one I've found. I found a plug just like it on the sensors on the firewall behind the IM, (emissions crap), but what else would it be for??
I bought these harness' for wiring in Vtec. what vtec wire would need this??

On my Vtec selenoid, there is a green plug(broken... gotta find another one), where the grey one goes, and a green wire coming out of it. What plugs into that wire? anything?

and the Red/orange wire from the vtec plug is just a ground right?
I've been useing this famous picture to help me, but it's a little different, obviously, than a SOHC, as i don't have the knock and the secondary intake sensor.


Anything else I should know about wiring wise?
