ive searched but im not sure if im searching right. sorry if thats my problem. however i have a 91 crx si. all this week ive been swapping a 90 obdo b18a1 into it. ive got it back on wheels now and really just have a few questions. what do i use as a vacuum source. the teg map and whatnot or the rex map and whatnot. so maybe if anyone has that info and a diagram of how to hook up properly would be appreciated. also i went ahead and used the teg radiator clutch cable throttle cable. is this all ok? it fits i just wanna know if ill have probs down the road. ive worked very long and very hard for this so i really want it to work any help will be awesome thanks.

I believe you can use the rex map sensor just fine, but don't take my word for it. If you have both, try using each one and check the results. Trial and error is the best method when no other option exists.

thanks

mr.crx

no not the rex map why would you do that you have to use the vacuum sensor from the motor it came from if you had a 1.5 your vacuum is completly diffrent!

ok i realize now that that was wrong on my part to think that. my bad. however today before i read that last post i started the rex up. it keeps right temp rolls on wheels and all that good stuff but with only the 1.5 map sensor it idled at 3200 rpm. bad i know so it accured to me to try and fit the teg vac ass. in but the teg has 2 tube like sensors and the rex only has one. so i moded the wires and bolted the teg vac ass. in and proceeded to hook it up like the teg diagram says. idled at 4400 rpm. so i stopped lokked and realized that the sensor on the throttle body that has a wire harness plug was completely broke off and then realized that thats where that plugged into.. so i bealize that sensor being broke has something to do with it reving so high. so moral of the story is if thats it which im positive thats it i need a whole new mt ls throttle body with the plug intact. any suggestions or where i can find one cheap would be greatly appriciated...
