Does OFT lock the tune? If he doesn't have the license he could have a tough time changing anything.

If he got the OFT with the car he can flash back to stock, unmarry it from the car with the free software online, then put an Ecutek license on and go from there.

That is just it. By the original post it is hard to tell if he actually got the OFT or if it was just previously tuned with it. Something tells me from his wording that he didn't get the whole thing.

Depends on what he paid for it.

Are the rods visible once the pan is removed?

You have a point. Well in that case, time for a new ecu! :D

(kidding of course)

He said he got it for a good deal, low priced. So i doubt the motor is built.

It's not built, it has the cheapest turbo kit installed.

I'm going to side with others here -- I doubt the engine has been touched. SBD kit goes for $3k, while a built engine is going to run $8k-12k installed. In general, the OFT is what gives it away though -- Any serious engine builder isn't going to cut corners with an OFT.

OP -- I'd recommend you turn down boost for sure, at least until you know the in-and-outs of this platform and engine. Not trying to be condescending -- but the fact that there is no paperwork at all tells me that the original owner wasn't particularly concerned with the build.

Turn it down ASAP and hope there isn't already damage done.

Original owner had paperwork, 2nd owner tossed it all. OP is 3rd owner.

All the guy wanted to know was if there was some external way to identify a built motor. Now everyone's telling him he bought a piece of shit. Lmao

You could always stick a endoscope down into the pot.

No one knows until you look, until then it's Schrödinger's cat.

And look for what? How would one go about telling upgraded parts from stock with an endoscope?
