S14 Auto to S13 5 speed, just need some verification..

[young-gunn]

okay, so I have a smashed, running S13, (no ABS, has a VLSD), and I want to swap that transmission into my S14 (no ABS, has a VLSD)

The main things I want to know are, will the driveshaft from either work?and what is this I keep getting told about not having a speed sensor? The S13 is pretty much a complete car so everything I should need is right there, what kind of problems will I run into when trying to do this swap? I searched and kind find anyone that knows for sure.

you cant use the s13 driveshaft, you need s14. you are thinking of the crank angle sensor(which you will need to purchase a 5 speed one). s14 trannys have them on the bellhousing, you can either a) swap bellhousings b)drill hole in s13 bellhousing to accept a 5 speed crank angle sensor, or c) run without and deal with a possible check engine light. buy the dvd, best 20 bux you can spend.

[young-gunn]

what am I supposed to do about the neutral start switch and the clutch switch off the 5 speed? we have already started the swap yesterday, and we just got the trannys out. also I read somewhere that an auto speed sensor will work, is the right?

U gotta search! It is easy to wire it up. There are alot of write ups. I did this a few years ago. S13 transmission into s14. It was easy. While u are down there take out the clutch dampener!

[young-gunn]

so It will start without a CAS? Can someone link me to a write up for this exact sawp? I have a S14 to S14 one but there are some parts missing that I would need.

[onepuff]

It will start and run fine you will just have a CEL. It is just for diagnosis of a misfire basically. Not needed if you dont mind the CEL on. Also the auto speed sensor will not work. It is bigger in diameter than the manual ss. The s13 ss will work but the speed will show double and you will hit the speed cut at around 60 mph:( You will need an oem s14 manual speed sensor definitely. Couple good writeups here should be all you need.

just leave it out. I did it no problem.

[young-gunn]

ok and I will need a 95+ speed sensor? I cant fab something up?

andwhat do I do with the neutral start switch? Remove it completely? Or just push it in and leave it there?

[1995240sxSE]

Nuetral safety switch, u r supposed to jumper it(trick car it is in neutral) so u can start it.

[kevinarich]

you have to trick the car in to thinking its in park, by jumping a couple wires at the fuse box under the hood. you need to run two wires from the neutral switch on the transmission, which is the one closest to the shifter to a pin on the Ecm and the other to ground. you dont have to worry about the 5th gear one. the reverse switch needs to be hooked up to the green and black wire coming off of the old inhibitor switch on the auto transmission. this will turn your back up lights on.

the CAS needs to be hooked up and you need the right ECM for this swap. its needs to be for your year car because the 96 is different from the 95 and the 97-98 is different from the 96.

You can take the auto drive line and use the yoke from your s13 and it will fit. thats what i did.

you dont need to buy a 20 dollar dvd to do this swap. thats why people started these forums in the first place. to help one another out, not make money.

well to do it again i would have ran those wires to the clutch pedal switch.

Yeah, thanks for being the first one to actually help me out on this. We will be working on it today and I am hoping to take it for a test drive by Noon. I had already bought the Standard driveshaft, the guys working on the driveshaft couldn't figure anything out (We are doing this in school and most people either dont feel like doing it, realized that lifting trannies is heavy and walked away to do something else, or just dont know what they are doingand it take forever to get anything done. So it has taken the majority of the week). And I do think I will be putting the Neutral start from the S13 in the S14, just for that factory feel.

[young-gunn]

okay, another question, do I take the automatic control module out entirely, or do I have to bolt it back up? I think the bracket is in the way of my clutch pedal and it is making the clutch pedal sit lower than it should.

[1995240sxSE]

I had mine in there for a while and then just took it out. You have to trick it into neutral not park. what year is your car. my 1995 I used the stock ecu and had no issues. It also (after the swap) had no speed govenor or rev limit. AUTO ECU IS FINE.

[1995240sxSE]

Check this out if u havent already, it should answer all ur ?'shttp://www.nicoclub.com/articles.php?id=183606

[young-gunn]

what do you mean to trick it into neutral? So I can just take it out or do I have to change some wires? I have a 95, but I didnt put the CAS in (S13 transmission), so I will have a CEL.

There isnt a write up on this anywhere (S13 into S14)?

and is there ANY way to make my Speed sensor read properly?

[1995240sxSE]

someone sent me a speed sensor from this forum. I dont remember what gen. it was from but mine was good.The CEL can be removed if u drop transmission and drill a hole in top of bellhousing. VERY easy to do!look at the picture in the thread the plug that has 2 wires in it, u basically have to make them connected all the time! I used two spade terminals and a piece of wire, stuck it in the female side of the plug and it started the 1st try.The transmissions/bellhousings are the same except the CAS in the s14's. Are u that concerned about a cel? Unplug the bulb! 1995's are obd1 where I am located there IS emissions, not for obd1 cars tho!

[young-gunn]

okay, so my swap is done (minus the speed sensor. It is on it's way).

But I did not get a CEL, even without the Crank Angle Sensor (my car was built in march '94, not OBD1?)

My speed reads double and my odometer rolls up faster (obviously)

I didnt jump the top sensor, just ran two wires to the switch on the clutch pedal (much smarter and still looks factory)

For now I just grinded my finishing plate on one side so it goes into first, I'll find the proper finishing plate later.

Thats about it, if anyone has a question about this swap, let me know.

if it's not obd2 then it's obd1.

[1995240sxSE]

it IS obd1!

[young-gunn]

how can I tell the difference between the two?

[1995240sxSE]

NO NO what I am saying is your car IS OBD1. you dont have to search.

Buy the DVD? thats the best advice ive heard yet.... could you direct me to the place to buy? i have a 95 S14 with a blown head gasket and an auto transmission. i have a coworker who is doin a 350 swap into his 92 S13 with a 5 speed. he told me everything he cant use for $700 so i want to swap everything over. just need to know the problems i will run into and what will fit and and and....LOL

[Dazzla]

The reason your speed shows double is wrong sensor. You need to purchase a S14 M/T speed sensor. That will fix that problem.
