What's up guys I got a 97 civic sedan with a d16y7 non vtec booooo! It has a loud discusting misfire I found out my valvess are stuk opem! Thinking about getting either a d16y8 vtec d16z6 or putting a d15 head onto my d16 block like a mini me swap which would be better looking for a bad ass dseriez! Skieza thx!

If it was misfiring, you want to make sure the block is still in good health.
Nice idea, D-series are under-rated. With the money spent on stock JDM B18C swaps (180hp i think) You can build a D-series turbo and have 300+ hp tuned .


The z6 is OBDI, which is a favorable type, you can tune it much more than the OBD2 y8. If I had the chance to choose between the two, i'd go with the z6, and get a modified ECU to tap out the potential

Ey thx man for the advise I wanted to go with the z6 I've just heard there faster and can have more horsepower I'm not really into the bseries stuff thanks a lot bro!

Im intrrested in how this turns out, and if vtec is a huge difference or is it just the sound.

 

[skieza]

Yes kali when it comes to vtec besides the loud noise it is a huge difference in performance when u drive a non vtec its like when u floor it to the ground u can fell it dosent even kick in!drive a vtec not one word to say haha!

Lmao @ vtec being a huge performance gain.

 

[Blayze2010]

OMG you have t3h v-tech????

 

[exodus_gs1]

I like this idea also how hard would it be to modify the ecu for the z6 head?

 

[CO671]

I should add, a mini-me swap will only pull out 20hp at best, which isn't too noticeable. Turbo it though, you may be well getting +80hp safely. On a stock block though, a turbo can only be safely tuned to 200hp before your internals are broken.

I don't know about all the different heads but many years ago I was given a non vtec head ( not sure if it was a y7). Compared to the z6 vtec head I was porting. The non vtec head had very small intake ports. They were the same in width, but the ceiling height was way different. For that reason alone if I was going to build for big power I would go with a vtec head. Keeping it a normal driver I don't know if I would mess with the hassle of a swap.

 

[TigBitties]

just put a y7 in and put a y8 intake manifold on. you are wasting money, you wont make quick d16

 

[TokyoSkies]

Single cams are a waste of money as it is, unless you build for boost. At that rate, you're gonna spend a lot of money.
Also, LOLOLOL at VTEC for performance.

 

[techavluis]

first off, be ready for all the d series haters.... your going to have MANY! but i would go d16Y8 (or should i say i did go) a lot of people go z6 cuz of oil but i think y8 is better all around. as for vtec.... power gain is little but is something....

 

[cgpEJ6]

LOL, VTEC on a SOHC is almost unnoticeable. It's not bad to have but you really aren't going to see a huge difference at all. I did a Y8 head swap on a Y7. There was some power gain sure, but it was minimal. I would do it again but don't have that high of expectations for it.

 

[Failsafe88]

Look you want to do my setup haha. Okay here is what you should do. You don't need to go to the z6. The difference between a z6 and y8 head is very minimal. Plenty of options for a y8 head when you decide to build it. With the y8 head you get vtec. It is also a simple swap to do on the y7 block. With the z6 you can read up few small problems you have to work around. If you need a y8 head i may have one for sale soon along with a clean throttle body and intake manifold for the y8. The y8 intake manifold is probably the best intake manifold stock for boost in the d series. As long as you don't want to do anything crazy like myself you could leave the head stock. If you are really interested let me know shoot me a pm.
