Okay I'll start like this I have already started my Jdm b20b non vtec swap on my 98 Honda civic basicly all that's done is motor and trans is mounted and axels an linkages are in an hooked up what wiring harness would I need to use I don't have factory

 

96-98 Civic EX harness should be the easiest.

 

^Yep. Or 97-98 CR-V. There is no direct swap harness, you're going to have to get a little bit creative/custom if you want it to fit 100%

 

Appreciate it !! What all will I need to do?

 

You might have to unwrap and reroute a couple of things, and the vtec wiring will be just hanging if you use a Y8 harness, but for the most part it should fit pretty close. Just make sure nothing is stretched or strained, and try to make it so that the harness doesn't touch anything (hoses, block, etc), just like the factory one does. You'll figure it out as soon as you start routing it around on the new motor.

 

Awesome thanks!
I'm using a p75 ecu
On the intake it's marked pr4 it was on on b18 b I have will intake work ?

 

Use a b18b intake manifold.

 

Yes. The P75 manifold is your friend.

 

So the pr4 won't work lol

 

Its off My b18b1

 

I posted my reply like that so if someone did search for the same issue they would know what to use.

 

Okay what about head gasket? Will a crib head gasket work

 

A what? Unless I'm missing something, use a stock head gasket.
