Default ?'s about the JDM D15b

What's the specs on this motor?

I have heard that some come with a LSD Tranny.. is this true?


Does anyone have this motor swap in their civics, and how is it compared to a d16z6/y8? Thanks.

basically a DX engine with VTEC. some came with optional LSD. compared to the D16, it is about the same.

Is there any place online that can deal these motors with the limited slip tranny?

3 stage VTEC

I'm not sure, but I think they only had an auto LSD.

Thanks for the input.

I'm thinking of running an Apex`i Ball bearing kit on one. All d16z6 parts would fit this motor, right?

Not Dx engine with VTEC. First of all there are several versions ranging from 90HP to 130HP. There are VTEC-E versions that say VTEC-E on the valve cover and there is the bad boy of them all, the three stage VTEC that says just HONDA on the grey valve cover and has two VTEC selenoids. Then there is the other 130HP version that says Honda and VTEC. If you doa search, VTEC.net has a good article about these motors. technically the engine is a 1.5L VX block with a SOHC VTEC D16Z6 head. I did the D15B 130HP swap in my cousins 5th gen DX using my exhaust and intake manifolds manifolds, wiring, dist., and tranny from my old D16Z6. I was pretty impressed when finished. Her car is definately faster than my civic was when it had the D series in it. What car would this be going in? The motor I bought for her cost $350.00 for a long block. I used the distributer and pretty much every other accessory from my D16Z6 and it worked out fine. There is still a problem with irratic idle at times but she just lives with it. She is in high school and loves the car now compared to her old notec 1.5. And I'm not sure if the stock manifold would give more power than the D16Z6 one since it was made for that motor but I'm betting they are the same anyway.

Oh, and no LSD is available. But they did have a nice CVT auto tranny. Actually most of thr 130HP versiosn are autos. The motor I bought was from an auto. The D16Z6 tranny bolted up no problem. and I forgot that I had to modify the bracket that holds the intake manifold up in the back because the holes were different but that was easily fixed with the dremmel.

My automatic LSD transmission is from a D15B, give me a second and I'll find you that article.

EDIT: Here it is, http://asia.vtec.net/article/d15b/ really good article.

My friend has one in his hatchback with I/H/E and nitrous, it's quick.

I can't find anybody local that has the D15B with the automatic LSD tranny - my auto tranny is on the way out and this would be a cool upgrade
