ok i have a 98 civic ex and a b18c type-nasty motor. i would like to know everything needed for that swap. i have bought motor mounts,an ecu, and complete wire harness. i posted a thread about the wire harness and they told me i should use the harness that is already on my civic with a conversion harness. but i put this motor in my old 2000 civic si and i had alot of problems with the conversion harness. so if i could id like to steer clear of the conversion harness unless i really need to use it. i know that i need axles. would i buy axles for any b series? anything i am leaveing out please let me know

uhm buy a b18type-r thats obd2 so you won't have to switch over. id call hasport or someone about the axles i don't personally know mine came with the swap. getting the motor and tranny? you might need shift linkage.

buy the few replacement things that are maintenance things. sparks, fuel, timing.

yeah i have already bought the engine. and its obd1

There's no easy way around the conversion harness. The reason is that OBD1 harnesses are a 2 piece design that split at the shock towers. OBD2 cars, yours is OBD2A, have a one piece design. There is no easy way to mate the OBD1 harness to the OBD2A harness; you'd have to do a lot of cutting and splicing which can introduce a ton more problems than you are trying to prevent. Best thing to do is use the existing EX harness and add wires for IAB. Then you'd use the conversion harness to run the OBD1 ECU.

buy axles for a 99-00 Si, just use the oem harness thats already on the car, it'll work on that motor and that motor is obd2

ok will the ex harness just plug right up to my engine?

b20hatchek

dur haha yeah it will plug right up

that'll move fam when you get it together

and b20 hatch i have a p28 ecu will that work? im asking because when i put the b18 in my last civic and tried to use the p73 with a conversion harness and it had all kinds of problems. but when i took the conversion harness off and plugged the b16 ecu(i forgot the name) it ran fine!!

b18civicej8 i have both ends of the obd1 harness the pieace that goes through the firewall and the rest, it still wont work?

B18CivicEJ8

No, cause the chassis harness it totally different. You'll end up with a total nightmare on your hands and it'll make you want to give up. The EX harness will work. You may have to extend a couple of wires and wire in IAB if you are using the GSR manifold. You may have to use this: http://rywire.com/store/obd2-10pin-o...f7098782aafcfc in order to run the OBD1 distributor.

b20hatchek

well you answered your own question, yeah your supposed to run a vtec ecu with vtec engines

b20hatchek

wait a min you said you had a 98 ex, thats a obd2 car, why are you messing with a obd1 harness, the plug that goes to the dizzy thier should only be 1 plug, you shouldnt have to get that obd1 to obd2 dizzy conversion

EngineGod2

swapping is all about doing ur research....suhwoo

jdm_ekcivic

Wait....OBD1 B18C5?

sorry guys i may have been misunderstood on a few things i am running the b18c type-r not gsr. b20 hatch hahaha i know man what i was saying was the p73 they sent me with the engine was making it run like poo. i put my "p06 i think" it is and it ran fine just not to the potential it should have been im sure. and i may have been wrong my car may be obd2 i cant really remember, ill go check right now. engine god turst me i know man thats what im trying to do now get it all right the first time so i dont have the engine in and its having all these problems. and finally jdm ek the ecu that i was sent was obd1 so thats what im guessing

b20hatchek

why dont you just getta type r ecu?

jdm_ekcivic

Unless your Civic is older then 96, it will be OBD2. And I would have just bought the ECU that goes with the engine. I never understand why people run all these random conversion harness and such when they can get everything with the engine and wire it up right.
