Well, did a pull to 145 and I think I have a rod knock now Oh well, we'll see what it is. Thought it might be the clutch at first, but the knocking sound is happening all the time... at idle, driving, clutch in or out, in gear or in nuetral and it gets really loud when driving (or rather, when I drove home). I don't understand what could have caused it; maybe I was pushing the car too hard too early .... lovin the boost. Oh well, new project to do anyways

Damn that didnt take long.. sorry to hear man!

Already?
You've done more work then most people in the NA section.
Another project underway I would assume.

What exactly is rod knock?

What bad luck you have....Man, aren't you pissed? *while I knock on wood*

damn.. hope it's nothing too serious. then again, maybe it's time to build up the motor for that single.

I believe it is when the engine's rod bearings slip, sometimes due to lack of good oil pressure. Check the TT Crankwalk Registry to see how problems can happen fast with a new clutch or engine upgrades for some reason.

I believe my case is either crankwalk or rod knock; I haven't done the clutch-switch bypass mod yet, so that could have been the problem, but to be honest, I was lazy with my install. I mean, I reesembled the motor with new gaskets, ARP headstuds, and simplified the motor, but I didn't really touch the bottom end, and I have a feeling that the bearings may have been sour from sitting for so long.

THE PLAN: I did a compression test and it was good. The camshaft is tightend down to speck, so the knock must be coming from the block unless I am missing something... so... Take the engine out. Find out what the problem is that's causing the knock whether it is from crankwalk, rod knock, etc. If it is one of those then hopefully the engine, crank and rods are ok. If not, I can convert my NA block into a TT one

Any advice guys?

Life's too short to get pissed, and honestly, having a project is more important to me than driving a fast car because I enjoy the work, even if it does consume money and time... it's an expensive hobbie.

isn't the clutch bypass mod a paperclip in a fuse switch under the pedal?...

Yeah, it is an easy mod that I didn't do because it was too exciting driving the car, and I was lazy after the work on the swap, and it is suppose to prevent crankwalk, but then again, many don't have it and are fine. Like I said before, probably a rod knock, not crankwalk. You know, I did adjust my pedal height... should have done that mod while I was down there.
