HELP!!! S13 ka into an S14, missing?

blink182house · Post by **blink182house** » Mon Nov 03, 2008 1:33 pm

Hey guys this is a buddy's car. The scenario is that the s14 KA motor was running strong and then after a major loss of oil threw a rod through the block. We picked up another KA from a guy, turned out to be an S13 KA... So I pulled the motor, and swapped absolutely everything from the S14 KA to the S13 KA (only thing that was from the s13 motor was oil pan to valve cover). We dropped it back in last night and hooked everything back up the same way, and the motor is running like pure crap! It wont idle and it sounds like a major miss. Are there any differences in the motors by any chance? I turned the motor around with a screw driver in cyl1 til it was all the way up and the 2nd to left notch on crank pulley was lined up. We set the distributor on one (which it was about one tooth off, cause otherwise we'd've been 180d off and it prob wouldnt have run at all) and ti still sounds like crap. Any ideas or suggestions? This is my friends daily driver, and I'd like to get it out of my shop to continue working on my own project. Thanks for any help or suggestions! Thank you!

timing timing timing. or vac leak.

like matt said, timing or vacuum leak. May I suggest spraying Brake Cleaner around the intake manifold and see if the idle picks up, that would be an easy way to find any air leaks. If you swapped the intake manifold, it might be a small gap giving you your problem. I had the same thing. By the way the s13 distributor and s14 distributor are different. But I assume you swapped that out. Be sure your intake is air tight after the MAF sensor or that could screw you up too!

Good Luck.

thanks man, no vacuum leaks anymore i fixed that, and EVERYTHING (distributor, intake mani, etc) all swapped over form s14. all wires hooked up, timing right, etc... its still feeling like a miss, i took some video im about to post up, both o2 sensors are bad though so im waiting on dude to give me money and ill go pick them up and swap them, only thing i can think of now.

rear o2 only checks operation of cat. do not need unless what the cel off. plugs/ gap are they new did you check gap. wires did you leave the tip of one on the old motor.

the distributor, wires, plugs all out of s14 original motor and good. getting fuel, getting air.

could have cracked a plug

or a bad plug wire, or you need to swap the temp sensor.

Have you tried a Subaru?

I swapped everything over from the s14 motor to the s13, but just to be positive where is this "temp sensor" located? and what temp sensor? I dont think its a bad plug or wire cause they were working on the original motor a week ago, the motor was strong it was just ran without oil and threw a rod out of stupidity due to the owner

(btw not myself haha). here's the vid, kinda cant hear anything but the FOERST start im holding the gas to keep it running some, 2nd time just started and let it die on its own.

temp sensor is on the front of the motor in the intake manifold.

would that show up on pulling codes as "TCC sensor"? and which specific one would that be (if you prefer for me to snap a pic and you just point it out, im willing to do so)? is that a common or good posibility of the problem cause the guy im doing all this for is a broke dude lol

matt would know.

how does it idle, does it misfire like crazy? if not, it might just be your Idle Air Control valve might be too tight making the idle too low, try twisting it counter clockwise to raise the idle a little bit.

it doesnt idle man, as in the video, the 2nd time i started it i just started it and let it go, it dies. yeah its not just the idle control valve... cant be, cause when i hold the gas (like in the 1st start in video) i can hear it sounding like a little miss or something in the exhaust/motor etc.... ga this is killing me!!!!
