Hey guys, New to the forum, signed up to see if I could pick a few brains and hopefully figure out what's happening with my car. It's a 1992 180SX, SR20DET. The car is perfectly fine when you start it up cold, as in, leave it overnight, crank it up in the morning. The issue arises when the car has warmed up (Say 4-5 minutes of driving). As soon as you hit around 3000RPM it feels like the clutch disengages and the revs just scream up without accelerating the car. I can hold it at around 3000RPM and it will slowly accelerate but if I put my foot down the revs just fly up. It has done 108 000kms, and I have recently installed a new clutch, that of a 300ZX. The problem existed before the new clutch and is exactly the same now, with the new clutch. The car is practically standard, apart from the basics, exhaust, BOV. I just find it strange that it runs awesome when it's cold. Any ideas? Cheers, Sublime180

Hi people, This problem has been happening for a while now. When the car is cold it is perfectly fine, runs as it should. Once it warms up, maybe 4-5minutes after ignition the problem kicks in. As soon as the revs hit around 3000rpm it's like you have jammed the clutch down or you've put it in neutral, the revs just shoot up. If you hold the accelerator so it's not right to the floor then you can kind of get the car to accelerate but very slowly...as soon as you plant it, or even three quarters down, the revs fly without the car accelerating. The weird thing is that when I start the car in the morning and take it for a thrash it's perfectly fine. It was happening before I installed a brand new clutch, and it is happening still. Has anyone else had this problem? The car has done around 108 000 kms and is mod free. I took it to a garage for a general check-up and got them to do a quick check but they couldn't see anything obvious. Any help or suggestions would be greatly appreciated. Cheers, Nick
