The 96-00 EX motor is the D16y8 right?

putting the Y8 intake and cat less exhaust mani on my Y7 should give me a little extra power right?

If any body has eigther of these parts laying around let me know and we can work out a little deal

i think i saw a thread about this about a week ago.

 

REALLY ?

 

It Does Work!!!

Me and My Step-dad did that same swap for a guy with a 94 civic hatch!!!

To tell you the truth it makes a lot of power! 2 weeks after the swap we went to the track here which is only an 8th mile and my friend wanted to run the hatch against a friends Type-S and the Type-s only beat him by 1/4 of a second!!!

Good Swap

doesn't look like anybody really gave you an answer. So here goes

96-00 EX IS the d16y8

Y8 intake manifold is like the type r manifold for d-series, or something like that.

Being catless it would be a more straight through flow, but i couldnt tell you if it gives you more power. You will probably throw a code because of your o2 sensor too.

 

I have the both the intake, and exhaust manifold. The intake manifold is for an auto, so you should only buy it if the car you're putting it on is an auto (check the link in my sig for more info).

Someone correct me if I'm wrong, or confirm that when doing the D16Y8 intake manifold install, you should buy one for an auto or manual tranny depending on the wether or not the tranny in your car is auto or manual, right?

 

what difference would it make?

and no I am not putting in on an Auto...

I just remember reading somewhere that they are different, so you would want to go wit ha manual Y8 IM.

 

anybody know why you would need to check tranny type when swapping intake manifolds?

 

I'm trying to find the thread that says why. I think it has to do with the IACV, or TB

 

anyone know if this will fit?

and anyone know what model this exhaust mani really came off?

it has to do with the way the iacv is mounted and the throttle body. they are both different on the auto and manual version of the y8.

I have my factory exhaust manifold for sale off of my 99 y8 manual. if you're interested message me or email me at fielding18@hotmail.com.

yes that will "fit" but you have to do something different with the fuel lines and I think you have to do something else wierd since it's obd1 and your car is obd2

edit:
that exhaust looks like it's off of a y8

 

It does not matter what tranny you have if your car has a Y7 engine and you are putting a Y8 manifold on. Here's the issue:

The Idle Air Control Valve (IACV) on all Y7 motors is a 3-wire type attached to the throttle body. This same t/b & IACV is used on the Y8 auto trans model. But the Y8 manual trans uses the standard t/b with a separate 2-wire IACV mounted on the back of the manifold.
All ECU's except for the Y8 auto and Y7 use the 2-wire type IACV.
You can use either manifold...BUT...if you are keeping the Y7 ecu it helps to get the automatic Y8 manifold and t/b setup, it goes on easiest. If you do get the manual version you need to block off the IACV holes in the back, put your Y7 t/b on the Y8 manifold and install the Y8 rotor & spring on the Y7 t/b. I would actually go this route in case later you want to convert to OBD1 or use the Y8 ecu, they you have the option of using the 2-wire setup.
that's how I did my manifold conversion. Right now I'm using stock Y7 t/b but I tapped my auto Y8 manifold for the 2-wire iacv so it's ready for the OBD1 + VTEC conversion in springtime.

 

how about the 92-95 civic EX and SI model mani's do they show the same kind of results?

They are the same as using a Y8 manual trans version, only the Y8 is better so I'd stick with that. I really like mine, it helps breathing alot from 5K to redline.

alright cool. You sound like you got some experience already with this. I am not planning on building this motor. i am just looking for a little cheap horse power right now. So I think I would rather just pick up the Y8 auto mani if it will be easier. With the mani what else am I going to need? Throttle body, dizzy, anything else?

 

D16Y8 Manifold Swap

 

Pics are good in the link but not much instruction... I also wrote a detailed tutorial on another forum of how I installed it and everything I came across during the install, etc...
http://www.superhonda.com/foru...80171

 

anyone else want to add anything?

 

So when doing the intake manifold swap I need the intake mani, the throttle body, and do I need the dizzy or can I use my D16y7 dizzy?

 

you do not need to change the dizzy. it has nothing to do the manifolds

True dat homies!!!

One thing though, make sure you get yourself an intake pipe for the EX before you do this, since yours won't fit anymore...

Also, if your manifold doesn't have the throttle cable bracket you'll need one before completing the install. It's only like $6 or so from a dealer.

as i was reading i was wondering if i was going to have to explain it but it seems you beat me to it, good job though thats 100% correct

also the z6 manifold off 92-95 ex/si is a very good manifold also, much arguement has occured over if the y8 is better than it or not, i say flip a coin or go for whats cheaper for you to get

I believe the debate isn't so much with the Z6 or Y8 manifolds, but with the design of the head itself. The intake runners are different, it's been said that the Y8 is better for midrange power due to the asymmetrical ports, while the Z6 is better for top end becuase it's symmetrical. However I think that data was determined on a SERIOUSLY high hp D16, not the typical street driven, mildly modded car.
