By vince72310
- Mon Jan 05, 2015 4:08 am #350726 i have a d15b7 on my 95 EGhatch with an auto tranny which is in the process of dying, i think the antifreeze and oil mixed because the next morning all my antifreeze was the floor and my radiator was completely empty and the oil pan and crankshaft had some of the green water from the antifreeze on it soooo i was thinking of getting a 92-95 d15b Vtec longblock for my car and i want to know if its a plug and play just the engine with the auto tranny :? its off the same year 92-95 so thats what im thinking the engine will fit right and plug into the auto tranny, help me if im wrong

Just to be clear, your engine is dying, not the auto tranny right?

i think the antifreeze and oil mixed because the next morning all my antifreeze was the floor and my radiator was completely empty and the oil pan and crankshaft had some of the green water from the antifreeze on it


Sounds like your head gasket might have went, allowing oil & water to mix.

It's a direct swap. Just unbolt your flex plate (what the autos have instead of a flywheel) from your d15b7 and put it on your jdm d15b. Use the auto's bolts too.

If your jdm d15b doesn't come with a distributor, you'll need one from a D16z6 or D15z1 - D15b7 will not bolt up.

You will need a vtec ecu and run 2 wires for vtec to work on your jdm D15B.
(basicially the same wiring as a mini-me swap: http://www.civic-eg.com/viewtopic.php?t=10)

The P08 is for the JDM D15B, be sure it is for an automatic tranny if you buy one.
Or Get a p28 from an AUTOMATIC 92-95 civic EX & Ignore the knock sensor on the jdm d15b. Ideally, you'll want to get a p28 chipped to run the proper P08 basemap, but it will run ok on a stock P28. Run the wires:

Here's a link to a pinout map: http://technet.ff-squad.com/wiring/obd1 ... matics.gif

The ONLY thing I'm not 100% sure on is if you will need to re-use your d15b7 throttle body. I think the auto TB's have an extra cable that goes to the auto tranny. So I would hang on to the auto d15b7 TB, because you will probably need it.
