S14 5spd Swap info needed.

[fuzionfuka]

My car is a 98 s14 base auto, im trying to make it manual. Do i need the 5spd ecu, or can i used my ecu and It just be hard-wired to work correctly.

What year 240sx's will make it the easiest to complete this conversion?

what parts are very cruicial to the 5spd conversion???

thank you

Okay first of all seach.

Anyway you need a 98 or 97 ECM. The auto wont work. Then you need to run a couple wires from the transmission to it. Then you need the OBD2 transmission or at least its bell housing. Then you need the S14 drive line. Clutch pedal, hardline. Thats all the S14 only parts needed. Everything else is pretty much the same for all of them.

You must wire those two sensors on your transmission other wise you will get a CEL in like 100 miles. I know it happened to me while my car was getting smogged.

An auto ecu should work...

From what ive heard the auto and manual ECU are exactly the same except for Idle Air control, the reason being on an auto the torque converter is constantly active...and puts load on the engine requiring a higher idle.

so Running an auto ecu with a manual transmission will just cause you to have an erratic idle. It happend to me when i did my 5 speed swap in my s13 ...and i used a Auto Ecu at first but it ran.

Can you say for sure its not the same with a 98? Id be interested to know why it wouldnt. Im guessing OBD2 systems are full of alot more redundant ****??

yes i would like to know also.

When i searched these are the answers i kept getting, they were confusing so i would just ask the right question i needed the answer to. thank you

In the 96 car, they used a 3 wire o2 sensor. In 97 they switched to a 4 wire. It will throw a code. I tried it. You also must use the manual ecu because the auto ECU unlike the S13 checks in on it constantly. It will throw codes for all the solonoids and so forth.

loving the purple, so really i all i need that matters is a 96+ ecu, 96+ 5spd transmission, 96+ lower wiringharness, and 69+ driveshaft

[driftneil]

Bro like he just said, you need a 97+ ecu. The 96 has 3 wires, the 97-98 has 4.

[fuzionfuka]

WOULD IT BE EAISER TO JUST DROP IN A 97+ 5SPD SWAP MOTOR AND ALL?

[kevinarich]

no.

you need the S14 manual drive shaft or at least the manual yoke. you dont need the the lower manual harness. just like 6 feet of wire and some connectors. You end up ripping the auto harness out cutting most off under the hood and keeping only the VSS and CAS wires only. Its a seperate harness. You can also throw that Auto transmission module in the garbage.

ok thank you
