what do i all need for this swap in a 99 civic ex
parts i have
motor
ecu
motor mounts
dc shift linkage
dc tranny
clutch flywheel
axles
anything else?

 

if you gonna use ex engine harness then you might be set to go

 

T bracket from an SI. Conversion harness for obd1 probably depending on which ecu you're using.

 

I got the obd2 Si Ecu the motor is out of a 99 Si but it is just the motor

 

You'll need to extend the primary O2 sensor to near the front of the cat at the end of the exhaust manifold header section

 

so i guess the wire for the o2 is to short what about the fuel rail and injectors i was going to use the one from the single cam

 

The EM1 shift linkage has a bend to clear the O2 sensor in the cat. If you're planning on running that sensor, you need the EM1's stabilizer linkage (the part that doesn't move). I found this out while trying to install a JDM ITR linkage on my EM1. The EM1 has the same cat/O2 sensor orientation as the EX.

You can't use the single cam fuel rail or injectors either. Use the EM1 rail and OBD1/OBD2 B series injectors depending on your ECU setup.

 

You can use D-series injectors depending on what they came from. D15B7, D16Z6, D16Y8 and all B-series are 240cc. most of the other D-series injectors are 180cc Really doesn't matter if they're OBD1 or OBD2 as far as the ECU is concerned, its just easier to get ones that plug into the OBD2 clips.

 

Would a B16 swap into my 1995 civic dx be a costly swap or if cost is a concern are there better choices? Thanks

 

Unless you are in love with VTEC, a lot of people do the B20Z with a DOHC VTEC transmission due to the gearing.

 

Thanks for your input. Helpful information.

 

I got to smog and I live in Cali no good here
