D15b Vti Swap
Alright i have a question about my civic and a b15b... Now i have a 95' Civic DX and i want to get the D15b To put in it. So my question is is that do my axels and what not work stock with this motor and what not becuase i want to make sure its a direct bolt in. The only thing that i wuold need is the ECU becuase im ruuning and 1.5 Non- VTEC. So i was wondering if any one could help me on this to make sure my swap goes the wy i want it to go. Also is there any thing i have to do with the wireing and what not to make the harness fit and stuff. so ya if you could help me out that would be great!!

I'm confused here...
'95 DX's came with a D15b motor, NOT a B15b. There's no such thing as a B15 motor, just a D15. There is no VTEC version of a D15 that I know of, the motor you are after I believe is a D16Z6 or a D16Y8, the Z6 is the '92- '95 Si hatchback as well as the '92-'95 EX motor, and the Y8 is the '96-'00 EX motor, both of which have VTEC. Your current motor is the D15b7, correct? Recheck your engine code on your current motor in your Civic, and we'll see what we can figure out from there.

You should just need the ECU and to run a few lines for Vtec. You should be able to use the stock axles, mounts, etc since it's all from a D-Series engine. Depending on what engine you had before you could use the stock tranny too (not CX or VX thought [I believe]).

 I went out on a limb and said "not that I know of" rather than "there isn't" just in case.  I really wasn't sure, but that makes sense. I also just read the topic of this states that his car might be a VTi model as well or at least using that engine. :o

Re: D15b Vti Swap
If you're feeling really cheap you can use just the longblock, as it will mount up to your tranny, and all the other ascessories in the bay. Then you only have to pin the vtec wires on the D15B's ECU, but you should get either a Si, or EX tranny to take full advantage of the D15B.

Re: Re: D15b Vti Swap
hey, not to hijack this thread or anything, but do any of you know about compatibility of this motor as far as pistons, rods, bearings, etc? Is it the same as the other d-series? I am thinking about going with this motor on another swap i'm doing...

[quote=Dumped91Hatch]...As far as the motor goes it is a 1.5l bottom end, so vx,cx bottom. The head is a Z6 head...QUOTE]
Thank you so much you just saved me a lot more $$$ than I have to spend; i had no clue that's what the motor was.

d15b
ok guys let me help you out a bit.....I have had one of these engines for a while and have done quite abit of research. First off, everything in your engine is interchangable as long as your current engine is mpfi. all trannys 89 and up, not 88 because of spline differences, will fit. Use the P08 ecu but get it from hyperducktuning.com. I have one and I wouldn't chose any other ecu. The RPT chip works best. When you wire the vtec make sure you wire the oil switch behind it as well.....trust me. This engine thrives on lots of cold air and high RPMs. It can go to 8k stock without batting an eye. As for the internals, you are partially right, the top end is a z6 head, and you'll need a 92-95 VX timing belt when you install. The bottom end is similar to the d15z1, but the rods are bigger and so are the journals. As far as I know so far no one has been able to locate upgraded lower end parts except for the pistons. In my opinion you can't get a better bang for your buck and it's one of the toughest out there. I've ran about 15 bottles through it and seems to get stronger each time I drive it. Just be careful who you buy it from. If you pay more than 500 shipped your getting ripped off.........e-mail me if you have questions... [email protected]
hope this was some help! later

Since it is a z6 head you use the z6 timing belt you could use the vx I suppose but it is vtec-e. Oh and it only revs to 7200 so your tach is off. Unless you use an ecu that has a higher redline. Here is a site on the Jdm D15b,http://asia.vtec.net/article/d15b/ most of it is accurate.

d15b
I must disagree. You are right, it is a d16z6 head however the bottom end is different then a d16z6. The bottom end is most similar to a d15z1 hence the reason you use a vx timing belt. As far as the rpms are concerned, I said that it can safely rev to 8k I didn't say that the stock p08 ecu would allow it to do so.
