My engine is being rebuilt
Well, some of you may have seen some references in some other threads to my engine being down for a rebuild. It started knocking about a month ago and has been sitting since waiting to be torn down by Buckley Racing. Today, Jim Buckley called me and said that the #5 bearing was spun. Mystery knock solved. Now the rebuild journey begins. He's looking for a good used crank now to replace mine. The other option is to rebuild my crank. But his first choice is to find a good used one that is well within spec.
Also, my #5 rod end is out of tolerance now. We will either find a used rod that is a match for the weight group of my other rods or go with aftermarket rods. Possibly Powder Rods. I'm told the Carillo rods won't work on the 964 without modification. Something to do with clearing the oil pump.
My car is going to be down for probably 5 or 6 weeks.

Did you get a reason for the #5 being spun?
Look at all of the oil pipes going over the rear wheel, including the 2 breathers, and make sure that they are not cut. My #5 spun from getting sand in the oil tank, through a worn oil breather hose.
If that's the case, the oiling system needs to be replaced, or you will rebuild more than once. Ask me how I know!

I use Carillo's in mine without any problem. It sounds like a competitior of Carillo's might have spread some stories...
Let us know how it goes!

No, just speculation. He said it looked like there was wear on the other rod bearings too.

He's planning to blueprint the engine and balance everything. Should be a great engine when its done. Of course, it ain't gonna be cheap...

Is the car for racing or a regular driver? What all do you think you might change out? If you're dealing with a racing shop, will you have the finished product dyno'd? I's love to hear how it goes, and what the final cost was.
Good luck!

Personally I dont think I would change from stock rods unless you are planning on raising the rev limit.
They are capable of handling lot of horsepower, and there is no reason why you couldnt just balance the stock rods.

I don't disagree at all. But in my case, one of my rods is damaged from the bearing failure, so I have to replace one anyway which isn't cheap. And then add in the cost of balancing all of them. Then add in the cost of ARP rod bolts. Suddenly, the delta between stock rods and something like Pauter or Carillo rods is much less. So, I guess you could argue that I am definitely overbuilding the engine. But it will be a stout engine when its done.

A GT3 oil pump is a nice mod if you are going to track it.

I happened to notice this set of 6 stock rods on ebay. 23 hours left. No bids. Looks like you could pick them up for $50.

+1 on stock rods being fine for just about any kind of HP you are going to make - just be sure to use the ARP bolts.
Check with Henry at Supertec - he has loads of extra rods. You'll want to recondition all of your rods anyway, so milling one down to match weight wouldn't be a big deal.
Only question is whether buying a used one, reconditioning all 6 and perhaps milling the new one will be cheaper than a whole new set of rods.
