I have a 95 civic cx hatch and just put a b16a in it and need help with hooking up the vtec. It's a p30 ecu. Pictures and diagrams would really help.

That helps a little bit but I don't know what wires on the engine are Spose to go to that spot inthe ecu

 

 

The green and brown dot those wires arnt on my vtec solenoid. I'll upload a pic later to show you what I mean.

 

That's because those are the wires to the VTEC pressure switch. Not the solenoid.

 

id your b16 a JDM motor some came with the pressure switch plugged. you will need a vtec solenoid form a d16z6 or b16 or b16 solenoid

 

Yea it's jdm I got it from hmotorsonline.

so hope those help you guys help me

 

Yeah where that bolt is you'll need to get a pressure switch from the junkyard, Honda or online somewhere. Any pressure switch 88-01 Honda or Acura will work.

 

k thanks. so that greenwire and red wire below the solenoid isnt the pressure switch I think it might be that because it's a b16a out of a 92 integra migh be wrong so confused got the wrong Haynes repair manual

so is the hole to the left where the pressuer switch is spose to go becose its just an empty hole

 

Yeah if theres no bolt in that location you're gonna need a whole VTEC solenoid.

 

Yeah if theres no bolt in that location you're gonna need a whole VTEC solenoid.That or search on here for VTEC pressure switch bypass.

 

Is that hard to change probley is but there's no way I'm taking this motor out to send it back to HMO. It was hard enough to get it in.

 

Also will the solenoid of a b16a2 go on the b16a because I know they have diffrent vtec engagement times but I don't know if that matters or not

 

Yeah it'll work.

 

I hate being such a noob!! at this lol but I cannot start my own thead yet so hopefully I will get some replies here I am swapping a b16a (obd0) into my 93 ex coupe. Im in no hurry to get it in b/c the z6 in it is running fine and I want to do it right. as far as ecu and wiring what kind of issues am I going to run into when it comes to dropping it in. I will be doing an all motor build on the b16 before swapping and any help with that would be greatly appreciated as well.

 

If you chip your stock ecu and run a Crome or other basemap you can eliminate the vtec pressure switch and knock sensor but you should still change over to a 4 wire o2 sensor
