Thread: jdm highport in a b14

so the engine in the daily took a dump. the best priced engine i can find locally is a jdm highport sr. is the process hard or very complicated to go from lowport to highport? ive done det and de-t swaps and installs so im not new to the game.

throttle cable and bracket you need from a highport car, you need the drum acclerator if you wanna keep cruise also. I got one for sale if yours don't come with it.

Pretty much, you might encounter small things along the way, but you should be able to sort them as you come across them.

As for the throttle cable, you can also modify the highport bracket to make use of the lowport cable. I went that route personally.

so sensors and wiring wise will the lowport harness work on the highport engine? or do i need to swap out sensors from lowport intake mani to highport mani?

coolant temp sensor has a different style plug, so for ease of install I'd swap over the lowport one to it. Everything else I recall being the same. Bear in mind that if you had EGR components, you won't anymore, so some plugs will be missing parts to plug to.

Distributor maybe and iacv? I would just swap your sensors since you know they work. Will eliminate problems once you start it.

so i finally got around to this swap and there is just one sensor that isnt transferring over to the highport manifold.. it bolts into the lowport egr... does it even matter since im not using an egr? should i just leave the harness unpluggd or should i plug the sensor on and leave it out?

Just leave that sensor unpluged . I just did a highport swap into my 94 and i went in with no problems .

I would plug that last sensor in and tape it up with the rest of the harness. ESP if you are using your original ECU. It might or might not throw a code. I'm pretty sure that sensor reads any air in the intake mani. So if it's just in the engine bay it shouldn't hurt anything.

dont 94 already come with a highport? im not so much worried about it throwing a code i dont have to worry about emissions here.. i just dont want it to put the car into limp mode or anything.. so just plug it in but leave it hanging back there? i was thinking of tapping the intake mani to screw it into.. but its pluggd into the emissions stuff on the lowport so i dont think itll do any difference..
