Knocking when engaging clutch

I hope this little tale helps some other Skyline owners out there.

About 10 months ago i purchased a lightened flywheel and 5 puck clutch from a performance shop in Sydney. (Not my usual mechanic)

So the very first time i drove it with new clutch, there was a knocking noise/vibration when engaging the clutch. I gave it 1000kms to settle as instructed then returned to complain about the grabby style of the clutch and also the knocking noise.

I was told that is what puck style clutches are like, and the knocking is my diff and U-joints, which need replacing. They would book me in the next day and repair for about $1000

So months have passed with me waiting for the thing to go BANG, including about 10 track days. Now the vibration got slightly worse (minimal) but i also mastered the art of driving around the problem.

Anyway with some much needed HP coming my way the next few months i decided to bite the bullet and get it all fixed. Now i do much of my own servicing:rolleyes: so the car only sees my mechanic for major services (once in 10 months)

My usual mechanic rings me and tell me today car is fixed, broken gearbox mount, $280 including labour (part was $170 alone)

Now when i drive the car any knocking is about 95% eliminated. Read PEFRECT considering 10 year old car with 135,000kms.

So this gets me thinking the gearbox mount must have already sheared one of its mounts when i had the clutch installed.(As the problem became evident that day) If i had of taken the car back to where i had the clutch done were they planning on charging me approx $1000 for a gearbox mount, only send me on my merry way?:D Plus driving around withthe broken mount has probably done some damage to bearings in the box???

Goes to show some mechanics must get away with charging some serious coin for fixing simple problems.

So to those mechanics and shops who rape for the quick $$$...:shake: ... you wont be seeing any more $$$ from me. My usual mechanic isnt cheap but can never really complain about the servicing.

      @Butters I can't tell you why but the bigger HKS step 2 cams improved low and mid end immensely. Turbos started spooling about 1k RPM less than before and the idle/vacuum was rock solid, it was an absolute thrill to drive, 3rd gear pulls hit 180kmh where previously only managed 160. Conversely, the milder poncoms in there now have a funky idle making it harder to get off the line, drives poorly in lower revs, laggy and makes less power/torque throughout. Feels better after I swapped the EBC but unless I put it on the Dyno again, I can't say how much better.

      Cams are not needed at this power level, they will create lag. The cam gears are a good idea though.

      @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.

      @Darrel It's so tempting to say e85 is borderline magic. It cools the intake charge, so if you're flirting with the edge of the turbos compressor map it helps dramatically cool down the hot air the turbos are pumping. It is very resistant to detonation so you can crank the timing, I don't really want to say you won't be knock limited anymore.... but you probably wont be knock limited anymore lol. I wouldn't be surprised if you made 20% more power swapping to e85 (provided you have the fuel system to support them, bigger injectors maybe bigger pump etc).
