early redtop into 97 Kouki

[noodl35]

I'm pretty sure I have everything done so far for the swap. I'm swapping in a 89-91 early year redtop into my 97 240sx. First I swapped the Smaller black plug on my KA water temp sensor onto my sr water temp sensor. Then I swapped the 97 KA transmission speed sensor(with the red gear at the end) onto my sr20det transmission. A guy that lives near me who did the swap onto his s13 said that theres no need ot swap the sensors. As long as the sr speed sensor has a red gear at the end, it should work? Actually, he didnt even swap the temp sensor as well. could this be a redtop to s13 deal? My entire harness is done. Got the z32 fuel filter. There anything else I needa change? Thanks.

They started making SR20's in 1991

Its seems like your moving right along on the process. Do you have an intercooler for the motor? If you provide a complete and ordered list of what you have we could better help you determine what you are missing and what needs to be done.

Lets see here yeah sorry it should be a 91 motor then, no cooling fins on the front.

I think thats bout it, i'm sure i forgot some stuff, if i do ill post it.

As for the water temp sensor, i heard that you must switch the black plug for the same year chassis. Example: I have a 91 redtop, should i switch for a 91 ka water temp sensor plug?

What's up redtop into Kouki buddy. I also have a redtop in a 97. The two things you mentioned are issues I have had. First the thermal transmitter. There are two coolant sensors, first, the coolant temp sensor which transmits the temp to the ECU is the left-most plug to the right of the throttle body. It has a red connector. You can use the S13 SR sensor as it transmits to the ECU. Secondly, there is a thermal transmittor, which is the right-most plug to the right of the throttle body. It has a black connector and you must use the sensor from the chassis year in this case 97. If you don't have it just go to Autozone or the like and buy a thermal transmitter for a 97 KA.

The transmission is another story altogether. I have the S13 SR transmission and the S13 vehicle speed sensor. My speedo & odometer read twice as fast. I have yet to install the S14 KA VSS to see if that would fix it.

So your saying that what i did was right? By using the 97 KA black water temp sensor plug on the right for the sr20det. I will see how my odometer and speedo work when i swap out my sr20det speed sensor for the 97 speed sensor. Thanks for the help!
