    Not at all, just noises which I deemed to be the turds in front of me. Nope.

    Back on the road! Hands down, Luk dual mass flywheel and Luk clutch is the absolute easiest on the knees. It's like butter! Quiet too. Also holds more torque so I can push it if I want to. Alignment tomorrow and look for the weird knocking at turning and all done. Pretty sure it's an endlink needing tightened.

    Next up, install all the stuff I bought.

    Hello @Raider. New member here.

    I have about 180k on the engine right now (before rebuild), mostly stock with the exception of a CAI.
    Currently I am rebuilding my engine with forged internals. I'm taking a similar path as you did, with a CS turbo, upgraded HPFP, catted downpipe, Cobb inlet and of-course a tune. My factory clutch held up all these while (180k). It probably would have lasted another 20k or so. So that gives you an idea of my driving style. :)

    On the good note, the main bearings looks almost brand new - hardly any wear at all. The rod bearings shows some wear. Cyl 3 & 4 rod bearings are down to their copper layers (barely). The oil rings were packed solid, which probably explains the oil consumption (1qt/1000 miles). But the cylinder walls and pistons look peachy! Except Cyl 3 has some light scoring on one side. Even the original honing is visible on 80% of the cylinder. The oil pump feels worn - can feel it a bit sticky at certain positions when turning. I dont know if thats how it normally feels.

    Anyways once all said and done, I hope to get it tuned to yield about 340-380ft-lbs of torque at the wheel (if that is even possible with a 91 octane). No alcohols/E85 etc planned. Would you recommend the stock/LUK clutch for this build? I really love the stock clutch feel and how it lasted for me. But lately been researching (reluctantly) a single mass.

    Thoughts?

    BTW do you still have the CS turbo? How do you like it?

    Stock clutch should hold that power fine.

    @Raider would you mind sharing how much you spent total for replacing your clutch? I might need to get my clutch replaced soon so I'm just doing my research.
