Help With My Stagea Please!

[suMfectz]

Hey guys, I've got a problem with my Stagea,

1st gear/2nd gear everything is great!

3rd gear when I hit 3000rpm and my foot is still down quite a bit, it will like just act as if I put it in Neutral and jump to 5000rpm then it will be like "holy shit what da faqqqq" then it will go back to like 4000rpm and continue to climb as well as the power in the car, this happens for 3rd/4th and 5th ( Maybe 2nd and 1st it's just the gears are too short to notice really... )

It's a 1998 Nissan Stagea RS-FOUr (RWD now ) apparently its Day Z edition however it's manual and it's got an NEO RB25DET in it..

I also replaced the spark plugs yesterday, car is running a lot better! However still the problem persisted

Any help please!

I got told it could be a boost leak?

Hope it's something small,

Cheers!

Slipping clutch.

^^^what he said...try pulling up a hill in third and then clutch kick (slam it to the floor and up quickly) while maintaining pressure on the accelerator - if your rear wheels smoke up the clutch is ok but if the revs don't come back instantly time for a new clutch.

Stock stageas can't do skids!
