Got mine lightened a fair bit and it made a big difference When people talk about loosing torque this is true, but only when taking off and flat changing. Your flywheel is basically a large lump of metal that spins with the motor, like anything, if it's lighter it requires less energy to change it's rotation speed, both acceleration and decelaration. OK: That's all well and good but what's it mean? I found when taking off easy at lights the engine required slightly more throttle to prevent stalling. That is a minor, and in my opinion only, draw back. The upside is your motor will be MUCH more responsive and have much more sensitive throttle feel. It was a big help for drifting ;o)

Regarding disconnection of TPS at idle, I never actually had to reset my computer. I did have the same problem twice a couple of months apart, I think this was due to accelerator cable stretching. If the problem re-occurs just try it again.... After all what have you got to loose (apart from your pinky on the fan blade (

Good luck

As per Cam's solution this will work if that seems to be the problem. I already had the fuel pumb earthed when I got the incosistent idle and stalling. Solution 2: Reset your TPS (Throttle Position Sensor) 1: Locate your TPS and make sure it is easy to disconnect the loom plug. 2: With you bonnet up un car, start your engine 3: Rev engine to 3000 rpm then return to idle 4: Repeat step 3 two more times 5: With engine still running disconnect your TPS (BEWARE FAN BLADES) 6: Reconnect TPS and your problem should be solved. If your car stalls at step 5, try whole process again, if it stalls again you have a faulty TPS, replace and all should be good. This made a huge differenct to general running my S13 (SR20DET) and solved my low or inconsistent idle and stalling problems. I do not know if this will work on skylines, but what have you got to loose it's FREE
