Part 2: d16y7 to d16y8 Intake Manifold swap 

Whats up guys I appreciate all the love Ive been ghost for a couple years cause I got out the Honda game but I’m back with a new project soon I’ll put up a video

Dude, I struggled with this for 4 years!!! I garaged my hatch because I could’t get the idle to come down. I went through countless throttle bodies and sensors and all it was, was a $2 part. You’re a life saver. Thanks man. Subbed.

Just did the same swap. Went through it with no issues because of watching your video. Thanks for making the video!!

You a life saver my civic use to be serging all the time ...now put new y7 gasket it's calm back to normal thanks

My God, I can't thank you enough for this video. I just did a auto 2 manual/engine swap on my sons '00 Civic Hatch and have this exact problem. The fact that you went over the entire intake manifold vacuum hose routing was great. New sub 👊

Bro I'm glad I watched your video! I had the 1000 to 2000rpm jump and thought it was my intake gasket. Thanks a lot.

So I have a d16y7 currently stock 1997 civic dx hatch and I got a new throttle body gasket at autozone. I was just making it new and cleaning the ivac and stuff. And when I was done I had an idol issue after not figuring it out I watched your video thinking I would do a y8 swap. Your gasket discovery fixed my issue. Thank you. I will be doing the y8 swap later.

Love your video it really helped me I watched tons of other ones been stuck on this for days thanks man

I'm about to do this, but, using a 3-stage d15B Intake manifold, which is nearly identical to the y8 mani. Should be interesting. I will post more when I am done. Thanks for the video and tips. This helps a lot.

I know the video is old. But I just want to say thanks. Because was very useful. The correct throttle body gasket is for a Civic 99-00 lx automatic. Because is the same one that my car have in the old intake manifold. Thanks

I'll try I'm not good with cars lol but I will love to learn

This is exactly what I need

I was literally just reading your thread on the forums lol

I have the same issue. Guess illl need to go get that gasket and hopefully fixes my issue. Mines bounces up n down. That’s my issue

Very informational, thank you so much

Good info bro thanks man

Thanks bro preciate the help

I have a cel. The mechanic got a throttle body from the junker with a denso IAC valve already installed. Apparently he got one for an automatic because the car is idling at 2k rpms. It's kinda hard to get something for a manual car since mostly everything they sell you is for an automatic.

Missing work today bc i did the swap in the past 2 days. Now car idles high when driving and surges stopped. It bogs really REALLY BAD! HELP!!!!!!!!

So a manual can’t have an idle air control valve?im just asking because I’m doing the swap rn I’m just tryna make sure before I rewire 😂

Sorry if it was covered but did u use the d16y7 fuel rail and injectors?

Bro do you have a wiring diagram of the evap where to connect this one?

Yo whats good. First I want to thank you for your videos because they're helping me out a lot. I did have 1 question about the Evap hose you had mentioned. I understand that one hose goes from the intake to the evap but I'm confused as to where the other hose goes. If you have an idea please let me know. Thanks.

Great vid, thx man😊😉

Hey man great video. Just curious. For the ecu. You didnt have repin? I just finished a d mini me swap and ran into a few issues....

Hell yeah man. Thanks

where does the longer line go ? "water tube"

Just one question what did you do with the vaccum hose connection for cruise control on back bottom side of intake

Good information sir plz tell me about mainfold housing thnx

I’m currently doing this to my 00 coupe I got a y8 manifold from a 99 5 speed and this manifold has a big vacuum port in between the 2-3 injection and idk what it’s for it wasn’t in this video

Yo I know this video is old but I did the swap Last night and I saw your video I'm pretty sure I got a few hoses wrong with the coolant. So theres a small little tube under the y8 mani. It's red and it turns do I plus that into the 2nd tube under the y8? Then I see that first tube on the y8 that goes right in front? Sorry if this crap don't make any sense.

Did you plug the air injection holes?

Yo I need help with mine bad I can't find nobody around me for help,I have a y7 motor with a y8 manifold but its a whole bunch of sbit not connect shit block off shot os crazy

Can I use y7 injectors and fuel rail for the y8 swap? And you said to use y7 throttle body gasket and y7 intake manifold gasket the y8 swap correct

I did mine. And starts overheating. Rad fan doesnt kick in till its on H temp. What could be the prob? All the coolant lines are correct. Tb gasket the same one as well.

ayyyyy bro Remember me? I told you about how much hp u can get out ur d16... anyway cool vid

deam bro nice video you post

a question is it mandatory to change the computer ???

That valve cover needs a paint job but great video 👍

I will still have to have a block off plate if I want to swap a y8 head on to a y7

Can you blow your motor if you hook the iac tubes wrong?

hi I have a d16y8 stock engine and want to put a aftermarket intake but don't know how to cancel the stock vacuum lines that go to the stock intake (hard lines)? my car is a 2000 civic ex

Yo my friend did a mini me swap ....he got y8 block and used y7 head vtec and with y7 intake..converted it from auto to manual he now have bad surging issue ..does he need y8 manifold ...manual ecu..

good video going do same for my y7.how much horsepower added or think added?

What size hoses did you use for the ones that were to short ?

I have a 99 d16y7 do i need a manifold of the same year or i can used one from 97

i cant adjust rpms , up and down 1500 to 2000rpms

Did you have to extend any wires? I did mines following your videos and the fuel injector wires won't reach...did you extend or cut open your harness?

Just finished the swap exactly like yours. Used the right tb gasket and everything the idle is still high... i have the map and tp sensors connected right. I have an extra connection here tho. Black connection with 2 wires. I don't see it in your video

hi , im ready to swap a y8 intake manifold on my d15z5 , i got y8 manifold gastey , but i don't have any idea of the throttle body gasket ... thanks yall

What gasket did you use for the intake manifold to block y7 or y8

What if you're running this setup on a automatic, would you need the manual or automatic TBI gasket?

Is that from a 96-98 or 99-00 y8 intake manifold? And to clarify did you used auto or manual manifold? Lmk I’m about to do my 00 ek hatch

Gonna put headers on it ?

I did the y8 head on a ZC but for some reason i get i issues with knock sensor Iv used two different Knock sensor and both fail, am using the bypass transducer but its not perfect at all times. Did you use a p28 ecu so elemenat the Knock sensor.

So you got rid of the iac valve ?

I did all this and now the car car starts but dies as soon as it starts. any ideas? I had an aftermarket throttle body so it didn't have the iacv on it and I had a plug off a civic that came with the y8 and spliced it in where there old iacv wired in and just used the stock place for iacv on the manifold. marked everything and took pictures and I don't know what's going on

hey man few questions i got the y8 mani with the iacv on the back side installed on can i just leave that on and just loop the hoses on the y8 iacv instead of making a block off plate or plugging the iacv holes some how? also did your manifold have the air injection mine has that and i just plan on using some jb weld read on the web they need to be filled i already have swapped a y8 vtec head on my y7 and have a vtec switch triggering vtec off the rpm works great now the y8 manifold is my next mod Thanks!

If I get an automatic y8 mani, do I still have to get that plate cover?

I swaped y8 motor for a y7 to my car can i only put the intake y8 normaly ??

He can’t I leave it instead of blocking it off, it’s not plugged in

Where u from how much will u charge me to do what u did to the intake

hay bro i did a minime. on a y7 block with y8 head. but now my oil light is on i think pump any. words for me. or wat kind of oil pump vtec or stock block

Ripped off y7 crap. Gonna do an oil catch can in place of PCV on the bottom part of the crank case. Better than putting oil back through intake.

hey man I'm having issues with this, I have a 2000 manual civic y8 IM on a 1998 y7 head.. for some reasons whenever I turn the car on it automatically revs all the way up.. I'm thinking it might be a sensor attached to the throttle body? I blocked off the holes and plugged everything in right.. any help would be appreciated

hows the vtec ? quicker?

Questions sir is it fine to run a d15b7 manifold on a d16y7 engine??

Bro add me on Facebook Benjamin Richards I bought a civic and they trashed all the hoses

oreilys is the same shit, backwards

Did you have to cut any of the wire loom to make the wires reach?
