S15 transmission?

[S15_silvia]

will the 6speed s15 transmission fit in a 97-98 240sx (s14) ive been looking all over and i cant find this info anywhere in the forums? and also the engine should fit fine right? it should just be a drop in or is that not true? i cant find anyone that has put an s15 engine n an s14 so im just makin sure everything will work before i order a clip

You need the rear diff, and I believe the driveshaft also. The speed sensor is in the diff. I don't know if you need anything else associated with the rear end after that.

EDIT: Heavy Throttle has done an S15 into an S14 chassis.http://srswap.com/html/gallery/tashi.htm

so does all that stuff bolt right on? is it heavythrottle.com?

The motor itself will drop right in. The transmission mount will require some modification (drilling) and such. The wiring is unknown because not many peeps do this to begin with, but I think it's not too different.

Good to have that info for the rear end Ben, thanks.

What kind of length differences are we talking here, KA transmission vs S15 transmission? and KA driveshaft vs SR driveshaft?

[S15_silvia]

yes thanks for the info? is it true that the 6 speed transmission off the s15 is weaker then the other trannys if so is it gonna break or are the other 5 speed trannies just really strong and this one is a lil weakers but its still good?

[S15_silvia]

also is it possible to put the s15 transmission on the s14 engine or maybe even an rb25?
