I just got done doing a JDM B16a OBD1 SIR swap into my Ek/Ej6 1998
And i trying to clean up my wires and make sure all my wires are plugged and what not so i can get rid of my CEL and troubleshoot the rest, My question is i have this two pin sensor coming out of my block(Back side) and i cant find the Sensor that's suppose to be plugged into my Thermostat housing since obd1 don't have them(As i read upon it) So where does this plug belong too since the thermostat housing doesn't have one? And what sensor is this on the back of the engine (CHECK PICTURES)



Im assuming the plug from the thermostat is suppose to be rewired into this sensor(Back side of the block) since i dont have the thermostat housing sensor? PLEASE CORRECT ME IF IM WRONG OR GUIDE ME NOT HERE TO ARGUE THANK YOU!

i think you may have purchased a 1st gen b16. that is the fan switch normally found on 1st gen blocks. newer motors have them on the thermostat housing

Aaron Cayabyab

I double checked and made sure it was the 170hp series but if it is the 160hp first gen ill be pissed but anyways the unplugged wire where the sensor(thermostat housing) i must rewire it to the back?

crx_si-r

yes. if you look at the thermsotat housing, you should see no sensor just the housing. just cut and extend your 2 fan switch wires (green and black) to that switch and you will be good to go.

Aaron Cayabyab

Ok lets clarify cut & extend the wires towards the back of the engine block and wire it up to those pins? And does it matter which wire goes to which? (Certified Electronics A.A.S) so im OCD about things when it comes to wiring!Haha thanks for your quick reply bro!

crx_si-r

correct. cut the connector that goes to your old fan switch (thermostat) and extend the wires to the 2 pin sensor by the oil filter. order doesnt matter.

or you can get a thermostat housing from a newer b-series (it should work) and install it onto your b16.

Aaron Cayabyab

Yeah that was my plan but i think it would be kinda hard trying to find the right fit since its a JDM motor (My opinion?) but since i know how to wire up maybe this route is cheaper and easier YEAH?! =]

crx_si-r

easiest and cheapest is to extend the wires

Aaron Cayabyab

Thanks once again bro! And you got me worried hopefully i dont have the 160hp JDM B16a Series so im researching again!Haha

crx_si-r

you should be able to tell by the serial number, right? also looks like your knock sensor is broken.

Aaron Cayabyab

Well they said if it starts with the 5million series its the 2nd gen 170hp also they said 1st gen is cable but as right now im using a hydro tranny so idk now haha
but this isnt my pictures i got them off google

crx_si-r

transmission doesnt matter. they all bolt up. im using a 95 b18b with a 93 gsr cable trans in my crx.

Aaron Cayabyab

interesting i have a EF 1991 Cable tranny im planning to drop my stock d16y7, would i be able to use my old cable tranny?

crx_si-r

yes.

Aaron Cayabyab

So i didnt need that Dam cable to hydro conversion! Thanks once again learned something new

crx_si-r

no. all you needed were the stock mounts for the EF. swap over the bracket that the mount on the t-belt bolts to from your stock EF motor. put it on the new motor and it all bolts back in. i used to have an 89 HB DX, converted to obd1 with a D16Z6 and a 90 Si cable trans.

Aaron Cayabyab

Yeah i know the swap is plug in play but wasnt sure if i needed a new tranny converting to hydro

mathai

Yea, that might b a 1st generation engine. I have a 2nd generation b16 and the sensor is on the thermostat housing.

serieal number starting w/ 1 or 5 doesnt always matter.(yes more times than not the sir1 was 1xxxxx and sir2 was 5xxxxx) I had a sir2 that serial number started w/ a 16xxxxx ...best way to identify it is by the intake manifold, cams, and pistons. The year stamp on the head as well, but thats not solid due to head and block swapping.

Aaron Cayabyab

Dam so i have a 160hp i hope it still kicks a$$
Yeah i heard looking at the manifold& head arnt as accurate due to half swaps i believe they call it.

Although heads could have been swapped here's how to find out the year
