180SX - S14 tranny = same? Strange noises after swap

[a13x.]

Hey guys,

I swapped out my worn 5gear tranny on my 1996 180SX (SR20DET) and replaced it with a S14 SR20DET transmisson.

They look basically the same and should be pnp am I right? Now I've got a weird noise when I engage the clutch. I thought the release bearing is fucked, so I ordered a new S14 release bearing and put that in. I noticed that the S14 bearing is slightly thinner than S13 SR.

Unfortunately nothing has changed. The noise only comes when engage the clutch. I can put in gears etc.

Any suggestions?

Thanks !

is the release bearing riding on the clutch 'fingers' all the time?
looks like a lot of wear on them in your picture? you should have a gap/ free play between the bearing and the pressure plate.

there are different length release bearing carriers.

The clutch has not been properly aligned or missing a pilot bushing in the engine

We swapped another gearbox in and its fine now.
