I'd reach out to Carbanh for a complete new build with a good core.

Looks like price still hasn't changed… Still $25k for a stroker build.

Increasing stroke swings the connecting rod in a wider swath and generates more side load on the piston and rings. That's the cause of increased bore wear. It also increases pistons speeds, which adds to it.

Improperly built/bad part choices would be the only logical reason.

There is that. But even well built ones seem to not last a long time. See post above.

I did highway pulls in my 991.1 GT3 against the MRF 4.2 6speed coming back from Thermal. That was insanely close and if that car was DCT might have been a toss up. But not sure if MRF is building those for customers.
I think Auto Talent in LA also coordinates builds. Just some other potential options if Dinan is unavailable.

early dinan motors went to a 94mm bore with a 83mm stroke to achieve the 4.6 compared to the rdsport strokers which used a 93mm piston with a 85mm stroke small change here but the dinan motor had a maximum piston velocity of 4493fpm compared to the rd sport motors with 4601 fpm.
