Mezger vs Newer

Does anyone have any info on the durability, reliability etc of the classic Mezger turbo block vs the newer DFI 3.8 L. Is the latter just too new for any reasonable comparison? I would think P would test/ and run these pretty hard before signing off on them. I am not really interested in which could be more easily modified, but which is better from the factory.

Hey Jim,

I asked the Training Manager at the dealership here in Kuwait about this specifically and here is what he said in general:
1- The two engines have the same basic engine block
2- The two engines' components are built from the same materials, alloys, etc...
3- The oiling system of the DFI engine is claimed to be more efficient than the 3.6L engine in that oil is micro-sprayed on top of the pistons which is claimed to greatly enhance lubrication.
4- The two engines will handle the same type of abuse, etc...
5- Compression ratio on the new engine is higher while boost on the new turbo is lower.

By and large, he said that the new engine should be at least as good as the old one in terms of reliability and longevity, etc...

Hope this helps,

Karim

If the new engine is as good or better then why is it not being used in any of the GT models? Not trying to be controversial but seriously want to know. Also why have the tuners not gone ahead with high HP kits for the new engine?

Engine is still very new for tuners to already explore its limits.

Cannot answer the first question though.

I am not taking sides on which engine is better.

I am merely relaying the information given to me.

Cheers

Karim, unfortunately, I believe your training manager is incorrect. Ask him what exactly is shared...with the exception for a few bolts, the two engines share no part numbers. Crankshaft. Connecting rods. Pistons. Cylinder housing. Valve drive. Tappets. Oil supply design. Camshaft bearing design. All different.

I think he will find it difficult to explain how two engines with no shared parts have "the same basic block."

There are no shared part numbers. Crankshaft. Connecting rods. Pistons. Cylinder housing. Valve drive. Tappets. Oil supply design. Camshaft bearing design. All different.
Unfortunately, the man is out of town until the 4th.
When he gets back, I will relay your question and comments and revert back to you with his answer.

Hi. I would like to know as well. I had heard from someone who sounded quite knowledgeable, I think named Cam on a different thread that the Mezger engines cost a great deal more to make and are widely regarded as the best/strongest that P made, which may make the 08-09s a great value relative to the price of the new ones. I would think this would be a big issue on this forum.

Yes the GT1 engine costs about twice as much as the wet sump DFI, that should tell you something. The tech is dead wrong, the two engines share nothing other than both being a flat 6 design, they couldn't be more different.

There is simply no comparison between mezger and 3,8lt engines...Neither from outside nor from inside view...As for durability...just forget it...when tuning begins internal parts of the new engine are way too weak for increased torque and hp...
However new car with flash and exhaust is extremely fast and has no problem in handling hp/lbft...above these levels internal modification is required...Keep in mind that raised compression ratio (due to dfi) is good for a stock engine giving more torque at low rpm byt is bad for bigger turbos where lower cr is needed...
Porsche again created an exceptional car with no contester in 500hp range...But for high hp tuning...major changes are needed...
