D15bv Vtec head swap mini me D15b with z6 head 

I didn't know u can you a d16y7 or d16y8 cam gear on a mini swap to fix that 1 tooth off. Great tip!!

scorps9398 yeah it took me a lot of research to figure it all out. I bought an adjustable cam gear also if the y7/8 can get didn’t work. But it did. I have 1500 miles on the motor already and it’s running great!

Great video! Did this but on b8 block! Same thing as b? Keep it up!!!!

Ruben Torres the build will be the same process, but I think the compression might be different due the the pistons in the b8. Might want to check on Wikipedia

@@MooreProjects cool! Thx! For reply!!!

KanineKat Tripod is a must!

Abraham Candas Awesome! Keep it up bro. You’ll enjoy it when you get done. I mated mine up with a Si trans and it pulls pretty hard!

Glad you enjoyed it! It was fun to make the video

Honda Mike figured it would be a good video. If you have any questions just ask away. There’s also a lot of good info in the comments on this video 👇🏻👇🏻

Yes would be the exact same. Make sure to remove your oil jet restrictor out of the block so vtec works. You’re welcome

Tmac0920 Mac runs good too. Especially with the Si trans and a lightweight flywheel

Hybrid vtec

Z6 timing belt and the Y8 timing belt are the same. You can reuse the z6 cam gear if you are installing it on a d16 bottom end, not the d15 bottom end. D16 deck height is taller. The reason for swapping cam gears is to compensate for the height difference when using a d15 with a vtec z6 head. If not the timing will be off 4.5 degrees. Or you can use a aftermarket cam gear made for the z6 camshaft and offset it 4.5 deg and be ok that way too

It will run with the Z6 cam gear, but not at the best spot for TDC. Could possibly get pre-detonation or a burnt valve eventually

@@MooreProjects I have a mini build I’m doing. I already bought a adjustable timing gear for the z6 head. So it will work I just have to adjust the timing?

@@Bennettbuilt892 correct. I’m not sure which direction you need to turn it but as long as you have an adjustable one then you can adjust it as needed

Honda Mike ok nice! So technically that wouldn’t be a mini me since it’s a 1.6l block. The mini me with the 1.5l block and vtec head bumping up the compression giving it close to the same power as the 1.6l. Still going to be a great build for you! I have that same setup on the side also. You can build it just like a z6 motor as far as timing belt, bolts, water pump, bearings and rings are concerned. Just make sure you remove the oil jet in the a6 block before installing your Vtec head

There is also the d15b from the 88-91 civics in Japan that are DPFI that had the non vtec head like USDM D15B1 and B2 And then the most common is the d15b from 92-95 with vtec. But yes you are correct there is a roller cam in those heads vs the Z6 head that is not.

Honda Mike yes make sure to use the original bottom end tensioner. So if you are using a A6 bottom end then use the A6 tensioner.

Honda Mike are you using a vtec d15b head? Or non vtec?

I live downtown Greenville off 385. I sent you a friend request on Facebook. I also have a v8 s10 350/350th. And a few other cool projects. Maybe we can help each other out in the future

Marvin Aguilera no problem. I’ve had soo many questions I think I might make a mini me Q&A video. To answer all the questions

Kareem Ellebry the EF hatch I bought has a JDM non vtec d15b in it when I first got it. Still was DPFI setup. I had a z6 engine with a bottom end knock I used the head from for this build

Also there are several kinds of d15b engines. Some were vtec. And some were non vtec

Noah Small best advice I can give before I went into doing this, lots of research, plenty of tools, and a repair manual. And of course RU-vid lol this was my first rebuild and it’s running great still

gameover818140 use a z6 timing belt and the d15 waterpump that normally goes on your block.

@@MooreProjects sorry to boder u but can you explain A little more what parts i need .Im not sure about the Head gasket,Block gasket(D15b7) or Head gasket(Z6 head) and timing belt D15b7 or z6? and what else i need...Hope u can answer !

Eduardo Real Moon use the y8 headgasket, z6 timing belt(same as the y8 belt), d15 water pump and tensioner. And you will need a y7/y8 cam gear or an adjustable cam gear whichever you prefer

It’s where the powerband of your motor is. So basically the stock tune and your engines performance is at its greatest. That’s what makes that feel and sound.

Hmmm I wonder where lol glad you enjoyed the video bro

TheNDex check the distributor o ring and the vtec solenoid gaskets. It will leak there run down making it look like the head gasket is leaking oil

If it’s not that then the head gasket could possibly of been installed upside down

@@MooreProjects I removed the head again and the head gasket was installed correctly. I applied copper spray this time and torque it down to specs. There's no more oil leak! I think the first time I was using a d16y8 torque specs and the copper spray seems to help. Also checked the vtec solenoid and it was a mess in there, cleaned it and no oil leaks there! Thx, she will be up and running very soon!

TheNDex glad to hear it man! Save the SOHC lol

Isaac Villalobos are you using a p28 ecu? And have the wires from the ecu going to the vtec solenoid? If so the only other thing is to make sure you don’t have a speed sensor problem otherwise vtec won’t work. It will throw a check engine light

2 options you have with the ecu.. if your soldering skill is good you can convert your current ecu to vtec if not you can buy a chipped p28 or a virgin p28 off ebay and use that ecu to activate vtec

rodney shelton z6 is the better flowing head from factory

@@MooreProjects so would it be better to do the z6 swap or just the head

rodney shelton z6 Swap for reliability. Z6 head swap for higher compression Mini Me that puts out the same or more power than a Z6

rodney shelton The Mini Me is reliable it put together correctly but I don’t know how long. This is my first Mini Me and I’ve got around 6000 miles on it with no issues. But I’ve seen Z6 motors last 250,000 miles easily

For turbo I would say a full z6 swap vs the mini me w/turbo. With the z6 you have more displacement and more room for your boost. And there is a lot more options for rods/piston combos with the 1.6L. My goal is for a all motor mini me. But I have a a6 block/z6 head combo on the side that I’m going to boost eventually

Shawn Bradshaw sounds like the wrong belt. Make sure you use a y8 belt.,I’ll look up the other belt to use. There is a Hyundai belt that works great on the mini me swaps as well. I’ll post it when I find it

Shawn Bradshaw make sure you turn the crankshaft counter clockwise, watch the cam gear move 3 teeth and then tighten the tensioner bolt

That's exactly what I did and it's still loose the tensioner ain't taking the slack out the belt

1996-1997 Hyundai Accent 1.5L DOHC timing belt, Gates part number T282, same teeth design and 105 teeth, close to the same width and has the same tooth pitch

Sounds to me like you might be running the b7 timing belt that has 106 teeth. Which is too long

You set your head to TDC using the plastic cover pointer and the factory z6 cam gear. Then swap to the adjustable cam gear. Make sure you are using a Z6 adj cam gear and not the y8. There is a difference. The z6 you will set it to about 4 degrees advanced. If you bought a y8 gear you need to set it to zero and start there. And your distributor you need to bring back to the center as your starting point also. Then use a timing light to get it dialed in at 12-14 Degrees BTDC

Take a wood screw and screw it in to the oil jet and take a pair of pliers and pull up. It is just held in with an o ring

Marty Mcfly no I think you might Be thinking of a catch can. The catch can line would Hook up from the back of your engine (black box on back of engine) to the catch can and then back to your valve cover. The oil plug your remove before installing the head just allows there to be more oil pressure for VTEC to engage on your vtec head

Danial Daneshmand do you have any junkyards near by? I would recommend pulling one or finding a local person selling one and then taking it to a machine shop to be pressure tested and decked before installing.

Danial Daneshmand being carbureted I doubt vtec would work since the computer is a p28 obd1 ecu and uses fuel injection with 4 injectors to run properly. You would be better off grabbing the intake that goes with the vtec head and doing the extra wires to go MPFI injection with 4 injectors

@@MooreProjects Yeah going EFI is probably the first step. just was wondering if it was possible to trigger the vtec with a solenoid rather than the ECU.

Danial Daneshmand actually there is a VTEC switch you can install to get it to work manually. It’s a manual vtec controller. Check on google and Honda Forums

Jerickson Dale use a d16y8 OEM headgasket

Thanks for the info. It fit and worked perfectly. I was wondering what timing belt I would use for this setup. I'm not sure which is on there now but it has a lot of slack and hits the engine mount when running.

Jerickson Dale you are probably using the d15 then. It’s 106 teeth were the z6 belt is 104

Correct., I used the z6 belt. Same as the y8 belt.

Kaeo Doronio use a b7/z6 cam gear with the y8 head on the d15

Unless you have a z6 cam in the y8 head, then you could keep the y8 cam gear.

Thank you so much!

Another quick question. What timing belt would I use for the z6 cam gear and y8 head?

Kaeo Doronio use either a z6 or y8 timing belt. Both are the same part number and teeth

ARP 208-4301. There is a link in my description for the head studs from SummitRacing.com

Is the d16 head stamped with a P08. If so then that’s a Z6 head. Did you hear it run first? What all does it come with? And what vehicle did they pull it out of

That is probably true. I’m pretty sure the d15b8 is the CRX HF model with only 8 valves. If so then yes you need to swap the pistons because there will be a chance of piston to valve clearance issue.

What pistons do you recommend?

And it’s a 93 Honda Civic hatchback

@@m4kapollo367 PM3 pistons if you are going for factory style power. P29 pistons are high compression so you can use those also. Or use SUZUKI Vitara pistons for low compression if going turbo

Awesome thanks so much on the input I’m going turbo so I’ll be going with Vitara pistons. My final question would be rods that you recommend ? I was planning on speed factory no notch rods ?

D15b vtec is a good engine and just as good as swapping a vtec head on a d15b2. So if you have one already assembled then I would just use that

No you need a z6 timing gear with the d16y8 head. The z6 and y8 are the same belt. The rods you can’t use. The journal size is different at the crank but the pistons are the same size diameter for the d15 and d16

@@crazybone552 I’m not sure honestly. I thought all the d15s had the same length rods. I think the heads are the only difference.

Boosted Imports that’s the same block I used. Mine was a D15b JDM block but it’s the same as the d15b1,d15b2,d15b7, and the d15z2 vtec

If you are wanting higher compression and vtec then go with a d16z6 head or d16y8 head. The y8 will give you the highest compression due to it having a smaller combustion chamber. If you want to have the easiest head swap with better flowing then use the d16a6 head off an Si CRX and it is straight bolt on and have a better cam than the b7 head

Thanks for the info!! Ok I’ll get the y8 head! And I can lock the vtec to work full time?

Boosted Imports yes you can. They call it the vtec killer. I’ve never personally used it before but it will work and keep vtec valve settings always set. So you might have to do a valve adjustment and it will probably get worse gas mileage but should run

Thanks man you a real one!

It’s worth it in my opinion. You gain like 25hp with the bump in compression and get vtec. If you also go with a Si trans with the shorter gear ratio it will be a night a day difference when driving

@@MooreProjects thanks and with a nice high-performance cam and better intake and head with basic work you think will be a nice combo for streets highways plus I wander if this combo be reliable to drive all over for example from buffalo NY to California and back etc

@@salrivera7578 most likely in your CRX it could have the A6 cam in it from the si model giving it the power bump and possibly an si transmission if I were to guess. Also CRX weigh less than other civics so the power to weigh ratio makes the biggest difference honestly.

@@salrivera7578 I wouldn’t worry too much about a cam unless you are planning to get it dyno tuned. But an intake wouldn’t hurt. The d series engines don’t have a lot of power increase until you add boost. Staying N/A you will have to spend a lot of money to get any kind of power and even then you would only top out around 160hp to the crank. I would personally save your money and just upgrade the transmission and put the vtec head on. And then just headers and intake manifold. And if you wanted to, go with a lighter flywheel and you’ll notice it will rev easier. And just have fun with it. It would keep it reliable and fun to drive. And save you money

No I’m from SC

Greenville, SC

Go with the d15b2 and the z6 head. If going for all motor I wouldn’t bore it 30 over unless your cylinder walls are out of round. That will lower your compression. You want the higher compression for all motor. That’s how the ‘mini-me’ gets the power. The vtec head has a smaller combustion chamber than the d15b2 head so it raises your compression giving it more power. Honestly if you are looking for more power than say 150hp then you should just get some rods and pistons and go turbo. You will have 200-300 hp no problem out of that setup and still come out way cheaper than a K swap

@@MooreProjects well I'm looking for something to play around 200 probably rods and pistons and the z6 and pull cam from 2000 rpm up be nice I think probably the turbo will do it I don't the cost the turbo set up or computer stuff really I love that d15b2 bottom end because my crx is light but when start running become a nice crawler on the road if you can help me give me some information how to go by doing it I will appreciate I saw prices in rods pistons and a nice cam that put from 2 to 72 rpms that cam will make the difference for the crank lower end I think

Sal Rivera with or without the turbo you still will have fun with it. I would suggest getting a Si transmission for the shorter gears. That’s what I have and I love it for all motor setup. When I go turbo I might go back with the DX transmission to give me more time between shifting and highway mileage. Stay tuned I’m going to turbo my civic in the near future this year. I have all the parts just don’t have a lot of time to do it at the moment

@@MooreProjects for a turbo set up then is better to stay with the d15b2 head that what you try to said

Sal Rivera for tuning purposes it’s easier to tune a non vtec head like the d15b2 but you get better performance gains if you use the vtec head

bmanbax1 thanks. So basically I took an old timing belt and a big huge pair of channel locks to turn the cam gear with.
