The jerking on downshift is basically independent of pucks. It's all a matter of driving style. The blip is called "heel-toeing'. The reason you get the jerk is that the engine and gearbox are not spinning at the same speed for the gear you are selecting. Heel-toeing matches the engine speed to the gearbox (road) speed.

3 puk - http://clutchnet.com/photos/3button_solid02.jpg

5 puk - http://www.mpautoparts.co.nz/images/PukPanel.gif

as u can see, the more puk's the greater contact area on the flywheel and easier to drive it will be.

feel is best described as where in the peddle travel the clutch starts engaging and how suddenly.

With OEM clutches... they have no feel really... once you get a button you'll learn all about feel for the clutch :rofl:

thats for sure..

I use an Exedy Hyper Carbon Twin plate.....kinda crazy if u drive it in heavy traffic.

ok.

i guess i have a final question.

Out of the clutches below, which one is the easiest to drive??? and when I down gear, there will not have a shudder...

-5 puk ceramic button

-9 puk ceramic button

-cushion button

select one from the above. the main important point is that I do not want the car to shudder when down gear...

Cheers. :thumbsup:

Hear this

ALL CERAMIC/BRASS MATERIALS WILL SHUDDER ON DOWNSHIFT IF ENGINE REVS ARE NOT MATCHED!!

Its due to the nature of the materials used...doest matter how many pucks or whatever. if you do not rev match, then your pretty much slipping the clutch everytime you downchange.

But, as for most driveable.. a 9 puck cushioned button will be the most driveable

Hong, going back a few posts a cushioned clutch has nothing to do with a sprug center rather a cushioning between each side of the clutch plates. A conventional button uses a single sheet of metal with puck either adhered or riveted to it. The Cushioned plates use two plates with a "spring" in-between. This "spring" takes the initial shock of the engagement rather then other driveline components such as gearboxes and diffs :laugh:

Bacially if the vehicle is mainly a daily driver, and a puck clutch is your preference, I would strongly suggest using a cushioned item.

The sprung center is purely a sound/vibration dampener.

If you need any further information or pricing on Genuine Exedy Clutch Kits drop me a line.

      What should I do next to hold the head on

      Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.

      Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.

      Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?

      1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
