Right gasket for Mini-Me.

By FrAnKeNsTeIn
- Tue Apr 12, 2011 7:52 pm #249998 I read the mini-mi sticky which was great.
I wondered though, the same swap to D16Z6.

If I use the Y8 gasket for the head I use z6 for the cover?

Also

If I do z6 intake & exhaust manifold I use z6 gaskets too right?

Cheers,

On subject, did you remove the middle layer of the y8 gasket on your install?

Should be in the 10's by using the y8 then bump a little more with the middle layer removed I anticipate.

What kind of difference performance wise is it for y8 vs. z6 head swap?

Obviously the OBII gives much more tune ability. I'm just not crazy about drilling into the manifold.

I dont understand what you mean? In his walk through he drills a hole in the manifold for the air sensor...

the only difference in the head in the higher compression due to the smaller combustion chambers. You don't have to drill into the IM for the IAT sensor you can also extend the wires and drill a hole in your intake tube (or cold air intake) right before the throttle body and install the IAT there.

The IM is aluminum so its easy to drill.

I see what you mean d-mon, I was under assumption that it was re wired to run obII.

More so nervous as to accidently effecting the way it flows with my hole.

You’re saying the y8 is higher compression than the z6 on b7 bottom?

With y8 gasket I’ve calc it at 10.1.1, what are you at?

The mini me setup I built here is long gone now, I sold it years ago when I was building up my d16z6.
I had the y8 head & IM, z6 head gasket and d15b7 bottom end.
I wanna say I was around 10.1 CR

The obd2 cars had the IAT sensor mounted in the intake tube, before the throttle body, so I would try it there. It doesn't seem to make any difference where you mount it. I didn't know that back in the day when I mounted mine to the IM.

- Thu Apr 14, 2011 4:05 am #250346 the iat tells the ecu the temperature of air coming into the manifold.
on stock civics, its pretty much the same as ambient underhood temp.
you could leave it dangling an it would have no adverse effect.

however with a CAI or turbo it can be significantly colder or warmer than ambient underhood temp so it becomes critical.

Thanks for the input on your build. :thumb:
