i have a 90 crx and a d15b vtec engine i want to put in2 it the ecu came w/ the engine alot of ppl have been having problems can i go to a honda dealership and pick up the stock harness 4 the d15b or do i need a conversion harness and a different ecu

 

since the search server is down right now.......
you can get a conversion harness and convert to obd-1 and use the ecu that came with the motor

 

Look up the D16Z6 swap in the the 88-91 and you're 90% there.

 

thanks guys any chance the starter alternater and the rest of the accessories will fit or is that just gonna nickel and dime me 2 death

 

you use all the same motor stuff

 

alright now the guy is telling me the crx is an LS i never heard of that i thought there was only si hf and dx im trying to figure out if the d15b vtec is gonna work w/ this car i keep seeing b18 swaps whenever i type in crx ls can any1 help me w/ this one?

 

i have a d15b. If its an LS crx theres a differetn way you do it but for any other one it goes right in stock tranny and everything, need to run a few more wires for vtec and a different 02 and you need to buy a wiring conversion so the new ecu meets up w/o hacking so motor ecu harness. Oh if the crx is an LS you have to talk to the guy who told you that and place his head in front of the front wheels and then do a burnout on his face for being a ***** bag.

 

yeah if you want help go to http://www.sohchondacom honda-tech is a bunch of idiots.

I guess that includes you too since you are on here also

 

thanks after checking out vehicle specs AND SEEING NOTHING ON AN LS ive come to the concusion its a dx hopefully it is cause the conversion harness is on its way

is is dual point fuel injection, if so it's a dx
and you will have to do an mpfi swap also

 

i dont no this is the first time ive worked on a honda and im in way over my head i know that behind the valve cover where the intakes comes out of its a little round thing not the longer thinner one i think it says pgm-fi on it its probly like 6 round if that helps

 

its a dx, u have to do the mpfi swap which i hear is a bitch.

 

if your engine looks like this, its a dx

it's not bad if you know what your doing. may as well do that and obd-1 conversion at the same time

 

by mpfi switch you mean the injectors intake manifold fuel rail throttle body etc or do u mean switching pins around on the ecu cause what im thinkin(keep in mind i no nothing bout hondas) the new d15b vtec engine i have is complete has the intake fuel rail all that stuff and the ecu im thinkin all i need to do is go get a stock wiring harness for the engine and rewire the whole thing oh and by theb way thanks for all the info guys

 

the stock wiring harness for the engine would be more work to do. what you want to do is to run more wires and repin the engine harness plug for them.

then you should (theres ways aroung it, but for simplicity's sake, lets say this way) convert it to odb1 with a conversion harness that plugs into your current ecu plugs and has the other ecu plugs on it. theres other wires you have to run, but i'm just trying to say it as simply as possible.

 

im startin to think id be better off dropping in a zc it puts out more power than the d15b vtec im lookin at its the same price and i can still use the same ecu thats in the crx right now. but do they make a turbokit and other bolt on goodies for that engine?

 

If is a dx then no matter if you put in a zc or a d15b, you are going to have to first convert to a mpfi.
