D15 non vtec. what to do?

By Animal78
- Wed Dec 21, 2011 1:35 am #286298 Well I have that engine in my my hatch and have been thinking about a swap but why engine should I go with? I want to do all motor this time. Probably do itb setup came etc. What's the easiest to swap in? I was thinking d16 which I have boosted one in the past but don't know how will it perform in a all motor car this hatch is lighter than my coupe was so I know that will help out alot. I had thought about building the 1.5 but I doubt the rods will handle alot of power.

Any thoughts are appreciated. Want to keep it running while I build something else to drop in. [/i]

instal d16z6 heayd on your block and change your rods and pistons ;)
this is my proposition ;)

I didn't think you had to.

I don't know right off the top of my head but I think the compression on my engine currently is only 8:1. That's a serious increase in compression. Spin that to 8k and make any real power and you have a disaster waiting. I will have to research the rods and pistons more to see what I can do. I don't know if there alot of replacement performance parts out there for the little d15. I am sure the crank or the rods or perhaps both are different from the 1.6.

- Wed Dec 21, 2011 4:27 am #286321 doing a mini-me with a d16y8 head will bump compression even more, around 10.5:1
Of course, that's only if you want to do a D series on a budget. You can make some real power with B or K swap if you want to spend more.


Also I thought stock compression was 9.5 or 9 for your motor. I know that D16z6 is 9.5.

if he will be open motor he should change everything enough no to do this later.

- Wed Dec 21, 2011 1:46 pm #286382 I may try the head swap. I assume I will also need a different Ecu or a way to control the vtec. If I went with the vtec it would be my first one. The last was a d16. I just built the block up and turbo'd the crap out of it. I put lots into it. Made 15psi. Lots of time tuning it. Lucky I knew someone that would help with that. All the Ecu stuff came from phearable and used crome to tune.

Anyway. I wonder how much power the head swap would make although its tempting to just get the entire d16 swap. I used a bunch of stuff from a wrecked 99 ex last time.

Or a complete shipped jdm d15b.

B7 block with the Y8 head. Not going through the trouble of wiring vtec just yet(she dont need that :lol: ) but ill let you guys know how it performs :thumb:

- Wed Dec 21, 2011 8:18 pm #286420 Well I will keep a look out for a head. What about just doing the d16y7 head (non vtec)? Anything to be had there. Where can I find a list of combustion chamber volumes for all the different heads? That would be some useful info.

Take a look at these pics. I have been trying to find out what head it has. I do not recall this intake being stock for the D15B7 engine. Correct me if I am wrong.
