Not really sure. This is a brand new bottom end from ams. Had 40 miles on it all below 3500rpm. Never boosted above 5lbs.

Ah, my bad --- tracking with you now. Definitely pull and ship --- that's not what you want your car to sound like right out of the box.

Arent the timing marks slightly different for the 2.3? Like 1/2 a tooth off? I thought i saw this somewhere...wasnt sure if it was just with the EVO 9 head.

I guess that I'm going to have too. Sucks though. I spent well over $5,000 on just the bottom end in this car and now I gotta rip it all back apart. Thats not to mention the $180 worth of tranny fluid, and t-case fluid im gonna loose, all the gaskets, head gasket, the new oil and water pump. I spent my whole vacation getting this thing to run, and it all goes to waste... man wtf...

Interesting point. More insight on this would be nice.

A sound clip would help. But also does it still clank when the motor warms up?

iTrader: (23)

yes

Now that I think about it, that wouldnt make any sense. I remember when there was no head on it the pistons would reach TDC and the mark would be dead on.

Even at TDC, if your valve pockets aren't designed for a high lift cam, you'll clip the valves on the crowns...

stock cams here...

So you did a 2.3 w/ stock cams?

wat.

Had the Tomei 280, but never installed due to stock valvetrain. I figured I'd break the engine in on the stockers, and then move to BR/Kelford 272 before the serious tuning began.

^ he put stock cams to diagnose a problem.
OP: post a vid clip with good sound recording and see if the gurus(not me) here could help.

Exactly, check everything possible first.

Does the noise ever go away? After the car is driven hard and is at full temperature, does the noise still exist? If so, it's probably not the pistons. Yes, the coated pistons will slow heat transfer through the piston, but not enough to prevent the pistons from expanding after a bit of hard driving.

The timing marks will only change when going from a 2.0 to a 2.4 block. The physical deck height difference is what causes the timing marks to change.
