Stock 951 rod part #
I am trying to figure out if i have been running a 944 NA motor that was turbocharged so ur help is appreciated. Basically i know i am running NA pistons and recently found out my Head was a NA head and now i was looking at the rods trying to see if i can tell if they are NA rods?

Daniel, come to think of it, your pistons looked a lot like NA pistons... aren't there DEEP dishes in the 944 turbo pistons? I could be wrong... What were your healthy-engine compression numbers? that could also be a reason you were blowing head gaskets all the time...

Pics of Ski's engine with head off... I'll try and find pics of my rebuild... brb...
Ok. found pics of Andy's rebuild (TheStig). Dude, I think you were running an NA engine... look at the difference in the pistons..

I am guessing here but I think the rod and main bearings are the same as the NA. As was the crankshaft and block. Piston rings are different though.

yeah, the Rods themselves however were forged in the 951 IIRC... also, if he was running a NA engine (meaning head which he already confirmed, pistons, rods, etc.) his compression would be higher, thus killing the engine... the skirts were broken off of his pistons, which would lead to the incredibly nasty scratches on the cylinders, as well as would indicate pre-detonation, which would be VERY easy to do when running 17 PSI or so on a high-compression motor... Daniel, when you get a chance, post pics of the pistons you pulled out of the car.

yes i knew i was running nA pistons in which is ok just can't run higher boost compression should have been 9 to 1 or somewhere in there. But i didn't know i had a NA head on top of everything plus i found welds on the side of the block that look like the motor probably came out of a wrecked car.

Post some pics of the rods. There are visible differences.
If the motor came out of a late 944 N/A it might have been higher compression than 9.7:1. In 87 it was raised to 10.2:1. Running 16psi basically means your engine was going to blow up eventually. Unless you had some hack like a thicker HG to reduce the compression, your results were inevitable.
