s14 transmission into s13?

[Adam240sx]

Ok, so my 5spd transmission in my sohc dont have reverse. I was told the s14 transmission is the same, although ive read their diff. Now I bought a s14 5spd transmission and want to swap it into my car. Will this work? If not wat will I need to make it work? Are the internals the same ? If so can I just swap the internals and be done with it? PLEASE HELP im confused.

someone that knows please help. what does it take, or should i just sell the s14 transmission and buy the sohc one?

I used a low mileage s14 transmission in my sohc for over a year. Its all exactly the same except the bell housing has a sensor in it for the s14. On my s13 I took out that sensor and threw it out, and made a small cover for it and used the same bolt to hold it in.

No issues no worries.

Just get a sohc trans.

Maybe you can swap the bell housings though. I really don't know for sure though, sorry I can't help.

u need to get the s13 sensor into the s14 transmission, or else u wont know how many miles per hour u doing, just get the new mag from PROJECT CAR.they are using a s14 transmission on a S13.

You want s13 dust boot. They are slightly different.

I leave the crank angle sensor on the bellhousing and shaved it instead of getting a plug for it.

There's no point of swapping he internals. It would be too much trouble for you unless you want to replace bearings and stuff to rebuild it.

I used a transmission from 95 for my 94 s13. Worked perfect.

so should i just fill the hole with something? what do you mean by shave it?and my driveshaft will it work fine with the back of the s14 transmission? and do i need a s14 or s13 throwout bearing? i appreciate all the help that everyone has posted. any other tips/help you can give would be great....

The bell housing, the tail shaft, the shifter its self, the weight, the internals, the mounting points, are all the exact same. The only difference is the hole in the top of the s14 transmission, which you have to seal some way. I just made a oval shaped piece with one hole on one side for a bolt to hold it in. Easy.

Even the 89-90 and 91-98 clutch is the exact same TOB and pilot bushing and all.

And use your s13 speed sensor, bolts in NP.
