yea i need to know if a d15b7 will just bolt in to my 1991 CRX Si?and will the wiring have to be done after or before the i bolt it in?

Any d series motor from 88-00 will bolt into a Crx, no prob.
The d15b7 is from the 92-95 Civic Dx, which is an OBD1 motor.
The Crx is OBD0 and the motor your putting in is OBD1, you will need to switchover/ jump to OBD1 and you will also need to use the d series cable transmission.

You can run it obd1 or you can stay obd0. If your worried about fuel maps and timing chip your obd0 ecu. A d15b7 doesn't justify the 150$ kits or the hours of soldering if you don't buy it.

 

[blackcrx18]

oh i see.what do i need to jump it over to obd1?can i still use the transmission that is on my d16a6 engine?

You would need a conversion kit for rywire.com. Or you can get your ecu chip and use everything else from your D16 except the engine, which would be D15b7/ Yes, you would use your tranny/clutch/flywheel.

Have you ever swapped an engine?

oh i can run it obd 0 and it will run fine?what do u mean by "if your worried about fuel maps and timing chip your obd0 ecu

yea those kits are like $150 arent they.which ecu are u talking about.no i havent swapped an engine before this is my first time and my friend know how to bolt it in and hes gonna help me,my bro was supposed to help me but he doesnt have enough time or so he says

Simple short answer:
Stay OBD0 & use your stock d16a6 transmission.

It won't run right on the wrong ECU. It may be somewhat expensive, to convert, you might want to consider rebuilding your A6.

Well, it will run, just not as well as it's supposed to.

Why are you putting this motor in anyway?
Like Tom said, overall, it might be cheaper to just rebuild the stock a6.

I wouldn't put the d15b7 in anyway, just to avoid the entire OBD issue,
and just rebuild the old stock d16a6.

WAIT WAIT WAIT a minute...

A D15b7 block is the same d block as a A6..Why in the world would he need to go obd1?...
Comeon guys stop confusing the issue here.

Can you swap in a b7 motor into your crx?...answer yes,but you need to keep a few things in mind.

To save $$$ keep your setup obd0.What I mean by that is this-
You will only use the B7's block and head.You need to reuse your old (A6)dizzy,Intake,TB,and exhaust manifold.
The B7 will run fine on a PM6...
Why are we going off on converting this guy to OBD1?
Although he CAN do it that way I doubt that is what this guy is thinking.

could not said it better myself. . .

Go this route for the simplest solution and least headaches.. . . There are improvments you can make in the future. . . but for a quick and easy swap this is the preferred method

I've been saying stay obd0. But convince the other 2 that you don't need to be the OBD of the engine. You can make an engine run perfect without having the 'proper code ecu'. And if he WAS really worried about it, he could always chip his PM6 ecu to run the P06 map for alot less then going obd1.

:doh:
Re-reading all of this NOW, i don't see why we made this soo difficult.
Cheapest and best route IS to simply use the d15b7 with the d16a6 distributor, intake, exhaust manifold and TB.

 

[blackcrx18]

oh ok i see thats what i wanted to know the simplest solution with the least headaches.oh heres a picture of the hole in my engine.

 

[hcrx333]

Why dont you go for a y8 swap if your thinking of converting or putting any sohc engine besides the a6 that you already have in there? Or just do a mini me on the a6.... anything else will not show performance gained from money spent. My thoughts anyway..... :?

Y8 swap would include spending a good bit of money buying the engine, the wiring kit and the ecu/dizzy and what not. Not worth it if your looking for the cheap route out.

Can't do a minime swap when you got a nice hole in the side of the block.

The d15b7 makes 108hp, just like the factory A6 did. It might not be a 'gain' but it ain't a lose.

B7 is rated at 102. I'm guessing the torque is down some too.

 

[blackcrx18]

yea thats weird that hole is causing my car not to work.what does minime an engine mean?and whats dizzy mean?

Umm well that "hole" is a bad thing.It means that a rod has busted loose and punched an undesirable opening in your block plus the rod is most likely wedged itself in a way as to lock up your motor from turning over.

As for what a mini-me is basically its taking a VTEC head and mounting it on a non-VTEC block.This does two things:1)increases the CR or compression ratio and 2)Gives you VTEC(Variable valve Timing and Electronic lift Control)...I wont get into what that is right now,but it gives you a more usable powerband.

Dizzy=a lazy way to write distributor(that thing hanging off of your motor's head with the wires coming out of it)

Does that help?
I was gonna say search noob,but forgot this isn't H-T.. :lol:
