d15 out of a CRX

By rflindy89
- Tue Mar 17, 2009 9:59 pm #103981 I am in the process of buying a D15b from a guy that came out of a CRX. He says it will bolt right up to my 1995 Honda Civic DX that also has a D15B. I just want to know if it will be a direct swap since its coming from a car that is 5 years older.

Thanks and sorry for the noob question

- Wed Mar 18, 2009 12:17 am #104010 is it a jdm d15b or a d15b2? Check the block stamp (front of the block, right next to where the engine bolts to the tranny)

If it is OBD0 then it will be a little extra work to get it to work in your DX

Also the dx has a d15b7,, unless yours was swapped with the jdm D15b (1.5L vtec motor)

big difference between the two.

If his is the d15b2 and yours is d15b7, then you can take the intake manifold from your b7 and put it on the b2 motor. You could swap heads too, for some reason the d15b7 makes about 10 or so more HP than the d15b2, I'm not sure if that is from a difference in the heads or not.

But anyhow besides that there really isnt much difference to make it next to impossible someone whose never done it probaly could.

- Wed Mar 18, 2009 2:31 pm #104120 alternator has a different plugs for the big round parts due to obd0 and obd1 harnesses though im not sure on this but i am going to try it unless someone on here says its a no go but find a obd0 harness from a 88-91 dx and cut of that plug and splice it into my harness....

So thats mainly that whole part there

But if i was you id look for a nice mini me head either a z6 or y8 alot more fun and stuff and that is what im doing with my D15b2 from a 90 ef hatch but anyhow goodluck with what ever you plan on doing

- Sun Mar 22, 2009 10:00 pm #105038 Ive been busy so ive been procrastinating about getting the new motor in the car plus the car is 30 miles away from where I live.

One more question, can I use the transmission that came out of my 95 Civic DX (D15B7) and connect it to my new motor D15B2. I just got home and it bolted up but I want to be sure it will operate properly before I throw the new engine and trans. into the car.

Any help is greatly apperciated!!! :thumb:
