the motor is a 2000 Y8 from a civic with a 1992 Z1 intake on it from a civic hatch VX... any advise on what intake gasket to run,, not looking for brand advise since I only run FelPro but would you advise using a new one for the 92 Vx intake or one for the 2000 Y8 head pattern.. thanks a bunch guys

tony_2018

oem one.

9d2civic

Ok OEM i get however my interest was should I get one for the 92 Z1 intake pattern or the 2000 Y8 head pattern.. from what I see on RockAuto they look different if you go and look the 92 Z1 intake gasket looks a bit different than the 2000 Y8 intake gasket... I am running a 2000 Y8 with a 1992 Z1 intake on it and want to get a new intake gasket for it but dont know what one to get.

Use the old type, that matches your manifold. The 1999-2000 gasket has an extra gap at the top for the air holes in the late manifolds. You don't want that.

excellent I will pick up one for the 92 Z1 intake... thanks for the help

Use a hondata gasket at least you'll get a improvement over stock.

TomCat39

Wasn't aware of that.

I prefer OEM intake gaskets over felpro. Felpro graphite IM gaskets make such a mess.

Does Hondata make most of the Honda IM gaskets or do they tend to cater to the performance motors only?

White_EG1

Yes you should be able to get one for anything from a d15b7 to a b18c5. It's just a IM gasket that is a improvement over stock, that not a lot of people know about.

They claim a 5% power increase because there gasket material is much more durable and heat resistant to incoming heat. If you look at some OG build sheets on here they used them a lot more some years back.

And oh yeah I'd never use a felpro some of my friends used them with no issues, but I always tell them around 25-50k (they're on rebuilt motors) it's gonna bite you in the *** lol.

Why are you running a tiny VX manifold? You're not going to make any power that way.

mk378

That's a good point I didn't notice. VX parts should be used only on a VTEC-E. For that they are essential. Any other version though isn't going to run right.

well since you asked and had a backup that inquires the same info here goes... my car is a 92 Civic hatch that had a severly knocking Z1,,, i got a killer deal on a 2000 Y8 with the original 5 speed still on it for a very fair price,, now I dont know alot about hondas so I put it out on the internet seeking help with it and found someone in Dayton name Tyler that said he could do the swap for me. now I had already bought the P28-A02 computer and a wire harness off of a 95 Civic because it was said that would make everything plug and play.. what little did I know how bad ole tyler was going to **** me in the ***,,, hence during the swap he failed to use the 95 harness even after I directed him to do so as well as other things.. needless to say he claimed the motor was bad and he could not get it running and gave me every excuse from here to there why and that it would never run since it say for several years and anyone with any knowledge of motors will tell you that it will never run,, I am currently building a garage and did not have time to mess with it so I told him to put it back together and I would pick it up and settle the bill... WELL when I showed up to retrieve my car i noticed how this jackass used his white mustang to push my car into the weeds hence the white scrapes across my back bumper as well as no shifter assembly in the car and half shafts were laying in the back.. I opened the hood to a absolute mess and needless to say a trip to jail was almost in the works with a assault charge..I held my own and loaded it up,,, not looking at things close before I left and after I got my wire harness and Y8 distributor back plus some other things I get it home and then look at it close to see the little **** stole my Y8 intake and put the one from the Z1 on the Y8 motor so its gone bye bye becasue if I go down there I will pummel him since half my suspention was either missing bolts or just left way loose. I did however get a dizzy harness for the Y8 distributor and what do you know it fired right up and ran. I have spent plenty of time replacing missing items and bolts to get it where I am at now and I am still not quite done but it has to sit for a while... needless to say when he swapped the intake he failed to replace the gasket and it has issues.. So is this situation my fault ,,, probably but only if i knew more about honda motors,, so with that I am still correcting his hack job work and fixing everything to get it useable... I am not looking to make this a power machine but only to use for work transportation so go fast is not important I dont care what is on it as long as It can get me from point to point without any problems

Now that I know what you're doing if you can find yourself a D16Z6 intake manfold and throttle body it's going to make like a whole lot easier for you. It will bolt up perfectly, it will function as it should and everything will plug in, get the injectors as well as the Z1 injectors are only 190CC and you'll more than likely throw codes for engine too rich/lean. You can get injectors for a D15B7, D16Z6 or any OBD1 D-series, all of those are 240CC. No matter what you do it'll never really run right with the Z1 intake manifold and throttle body on their.

mk378

I did think the injectors were different. That alone will cause major problems, if it runs at all. You do have to swap a lot of stuff to convert a VX into something else, or vice versa.

I would also suggest a compression test on your supposedly good used D16Y8 engine, before you spend more money on the project.

9d2civic

the hack did put the Z1 injectors in the Y8 motor and I do remember reading that they dont flow the cc that the Y8 wants so with that I did order some new injectors for a 95 EX with a 16 motor... the Y8 injectors are one of the items I did manage to get back from him however they are OBD2 so its a nay nay on using them. I will look for the intake you advised getting however do I get a intake gasket for the D16Z6 and if so what year and what car did they come in ,,, such as a 95 Ex or ???

9d2civic

oh yea he even stole my stinking battery hold down... what a troll

mk378

Yes you're building an OBD1 EX. The 1992-95 EX was the only one with regular VTEC.

You may want or need to swap your engine harness, if the electrical plugs on the 240cc injectors are physically different.

TomCat39

It's a bit more complicated than that. The obd2 (d16Y7/8/5) the harness went from ECU all the way through the engine and components.

The obd1 engines D15B8/7, D15Z1 and D16Z6 had a separate engine harness that plugs into the shock tower harness that went to the ECU.

To use the Y8 injectors you would need to rape the Y8 harness for the injector plugs and swap out the plugs on an OBD1 harness.

If my memory is good the D15B8 and the D15Z1 had the small injectors while the B7 and Z6 had the larger injectors. I could be confused on the B8...

The reason why the advise is for the D16Z6 intake manifold is that the obd1 fuel rail that fits the chassis will work without modification and the Z6 IM will feed the Y8 motor well. If you try and keep to the Y8 IM then you have additional challenges with the fuel rail as the regulators are on opposite sides and the chassis expects it on the drivers side while the Y8 has it on the passenger side. And the obd1 fuel rail doesn't bolt up to the Y8 IM without modification.

The other thing to be aware of with using the Y8 motor and an obd1 ecu P28 (Z6 ECU) is the ignition timing marks on the Y8 pulley are 12* BTDC while the obd1 ignition timing is 16* BTDC. There is a 4 degree variance on the pulley timing marks.
