S13 transmission into S14

[Dazzla]

Hey guys, been reading up on this online and wanted to get a few questions answered.

I realize that everything is pretty much plug and play except for the CAS and something about bell-housing bolts? And the speed sensor? Can someone explain those?

So for those would I need a speed sensor out of a manual s14, and do I drill the bell-housing bolts or something? I'm kind of lost on that part. If someone has pics or has done it and can make that abit more clear for me it would be awesome.

Also in a 1995 automatic s14, would you need a new ECU, I'd imagine that the automatic ECU will throw a CEL? Or will the auto ECU be fine?

thanks!

There have been several write-ups, etc. regarding this swap on Nico and other sites. Please look around some more and if you still have questions please ask.

EDIT: OK, to help you out. Yes, you need an s14 m/t speed sensor. If using an s13 bellhousing, you need to drill (2) holes, one tapped for the CKPS (CAS). The auto ECU will work, but will throw codes.

Awesome that is helpful! Will it make any difference if my car is OBD1 or ODB-II?

So does anyone have pictures of those holes? I'm assuming one hole is just so that the bellhousing will fit, the other is for the CAS.

So all I need is a s14 m/t speed sensor? The CAS hole can be anywhere or is there a specific place where they have to be drilled?

ECU I can always replace later if I can get it working in the first place.

[diggles240]

Sorry, both holes are for the CKPS. One is tapped and the other is just a hole for the CKPS and this does need to be in a specific place on top of the bellhousing. Also, don't forget your reverse switch for reverse lights (imagine that one). That and the speed sensor are required for function. I have some pics for the CKPS location- I will see if I can find them.

[Dazzla]

awesome, that would be perfect! Thanks!

and a manual s14 driveshaft is needed too right? anything else I might be missing? I've got a s13 5-speed swap pretty much complete.

you will need an s14 manual driveshaft.

as for the cas from what i hear you need it for obd2 s14's i have heard you need it even if it is obd1 but a few people have swapped with an s13 trans without the cas and not thrown a code.

you do need an s14 speed sensor because the s13 sensor will make your speed read double.

and for the bellhousing bolts the manual bolts are longer then the auto bolts.

Pics courtesy of motoman399- thanks alex. For reference the raised portion of the bellhousing where the CKPS is located is approximately 1/16" thick. You can use a washer or some other type of spacer to achieve the same effect.

thanks for that kind sir. i will be using this to drill my s13 bellhousing

I am glad you can use it, but thank motoman399 for the dimensions.

If my 240 has ABS and LSD. Can I use ANY s14 manual driveshaft, or does it have to be a specific one if it has ABS or LSD?

[diggles240]

If you have ABS, then you need an ABS m/t driveshaft. The ABS and non-ABS driveshafts are different lengths. Look in section PD of the FSM and it will tell you this. I strongly suggest doing a lot more research and/or purchasing the 5 speed swap DVD from JDS Performance. Josh does an excellent job of demonstrating pretty much everthing concerning the swap. Also, please read the links that I posted. All of the questions you have asked have been answered on the interwebz. Good luck with your swap.

+1 on that. i just watched the dvd again . its my 5 speed swap bible! lol

If I use a non-ABS driveshaft, it will still be fine right...its just I wont have ABS and the light will be on in my dash?

[sebazztard]

that question was just answered ^^^^^^

it has to be specific to your car, the driveshafts are different for abs and non abs models. there is no way around it whatsoever, zero. your car will still run w/o the sensor if you dont want to bother drilling into your bellhousing, but it will throw a code w/o. theres a lot of iffy replies when everyone says search, i find that amusing. the 5 speed swap dvd is VERY informative, well worth the 22 bux i spent. i suggest buying this just as a reference if anything plus there is some wiring to be done which this dvd also covers.

[Dazzla]

damn, that just means its going to be even more difficult to find that damn driveshaft. isn't there a way around it? removing the ABS? lol

its impossible to find a s14 driveshaft here, let alone a manual and ABS one.

[diggles240]

I would consider purchasing a one-piece driveshaft if OEM ones are hard to come by in your area. Just a thought though.

[diggles240]

theres a lot of iffy replies

Please point out if you don't mind. I enjoy learning.
