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

if revs are climbing and speed isn't then it is a clutch issue. there is a very good chance your flywheel is shagged, and continuing to drive it with the clutch slipping like it is is only making hte situation worse.

it may be a clutch adjustment issue, but by the sounds of it you have probably screwed the clutch and flywheel, so you would need to replace both. i'd suggest getting a heavy duty clutch for a SR20. if you used a vg30 (300zx) clutch then it would've been one from a NA (since the turbo ones are bigger and won't fit from what i've read) it probably isn't holding up to the sudden increase in torque of the turbo engine and has probably contributed to your problem.

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
