Hey Guys,
Here is the scoop. I own a 93 nx2000 manual non abs version. I have been having an on going very strange set of problems (have read all posts related). Did an engine swap with the same sr20de from Japan, Some minor differences such as alternator distributor a little different anyway I also replaced the clutch when we pulled tranny of I was amazed to see the clutch bearing had been hammered (I think) on to the input shaft as it appeared to be too small for the shaft after speaking and knowing all owners this is the orig tanny and clutch (all work had been done by Nissan other than that). Bought new clutch for this vehicle bearing too small for input shaft (remember orig tranny) sent it back, new one same problem. Ordered new bearing from Nissan (gave vin number) too small for shaft So we ground out some material from the bearing to make it fit which it did tight!! Have gone through 3 clutches all within 300 miles 1st broke in centre of pressure plate, the last two broke at the springs…thought crappy Fenco clutch and maybe drove too hard too quick. So then ordered a genuine Nissan nx2000 clutch and a new fly wheel new motor mounts, clutch cable (checked run out ..perfect) bearing again too small for input shaft. Once installed with new flywheel when shifting the clutch/tranny area makes a strange grating kind growling/grinding sound but not in nuteral..was advised that is a bad tranny (bearing or something) I am skeptical as it never made this sound before with other clutches (even though they broke) and was unsure as to how tranny can go bad sitting in lot. By the way with this new Nissan clutch I can put it in gear like butter without even using the clutch. is that strange and does that indicate something. Here are my questions. 1) Any idea how the input shaft can be too big if orig Nissan tranny. 2) Does anything sound like clutches being installed wrong? 3) Any idea on the new noise I am hearing only after Nissan clutch installed. is it a CLUTCH noise or TRANNY noise…the mechanic is getting frustrated with having to do all this work over and over. I want to make sure he is installing right. By the way even though i changed for the same engine sr20de the japaneese engine is so much faster..no joke it is like a bullet is there a difference??? compression was measured at 194!! cause the pedal does not lie
Thanks in advance Andy. FL

You should check the ID number of the tranny and see if it jives with what it's supposed to be.

I have no clue what your problem could be, but it seems to me like you've had alot of clutches that were made for a NX2000 (not 1600, right?) and they should work since thousands of others on this board have done the same with no problems.

If the input shaft is wrong, then something is weird with your car. I was wondering if you had a tranny from something else, like a 1600 or something. I've never done a clutch job on an NX, so I can't really make suggestions, but definitely something is wrong when parts made for your car just don't fit.

Also, that noise could possibly be the bearings on the input shaft going bad, and it might all be related...

Pictures would be helpful...

2000HP (dyno tested) NX 2000 (BY MISTATKE)

Just found out that the sr20de engine I got from Japan for my nx2000 is way different from the sr20de stock that came in it….. power that is!!!. This j-spec engine is putting out 200 hp..imagine on a little nx what a beast this is!!. Anyway because of this it was burning up clutches due to the stock transmission getting to hot as it could not deal with this powerful engine and passed this on to the clutches by burning them up and breaking (4 in total). So I have the proper tranny that matches the engine on the way. This is going to be (unintentionally) a ridiculously fast nx2000..can’t wait. Any guesses on time before I take it to the track….anybody??

Ps still does not explain the input shaft on orig tranny being too big..but no worries now!!
