I bought a Civic type R throttle for my CRX B16a and noticed it has two electrical connectors while the OEM has only one. Can I use this throttle with only one electrical connection?

 

If i am not mistaken, they are the MAP sensor and the TPS.

You can use the TPS as for the MAP, since you have a first gen b16 (if you do), the MAP sensor is mounted onto your firewall. I believe you can use either one, but not exactly sure.

 

i don't think you can't, you need the map sensor. you'll have to extend the wires for it to plug into the map sensor. not much work.

just wondering, what's the bore size on the ctr tb? i thought they were all the same for all b16a or b16b. 58.5mm

 

I remember measuring it on the intake and exhaust sides in order to compare it to my ctr intake manifold size but I don't remember exactly if it was 63mm. I'm sure it was NOT 58.5mm
