Case House Performance

This is Jeffs 08 C6z, she was originally brought in for a misfire to which we found issues with the PRC heads (no surprise) but it hurt the bottom end as well. Our machinist Scott spearheaded the engine rebuild through our in house machine work. We did a full OEM rebuild with the factory rotating assembly. Jeff got his hands on oem Ls7 heads to replace the PRC heads and we sent them out to Brett for his stage 2 upgrade.

Now i know we just posted about our highest hp C6Z a month or so ago. But jeffs car now wears that crown, he made 8 more hp than the previous car. Both insanely fast cars and very capable cars that will be feared on the street and track.

This is Mike's 13 C6 A6 car that we did a full ls3 kit on. We also did 6l80 converter, C6 aux fuel system and FID injectors to support the added hp. She picked up almost 200hp over his base line NA hp. Thats incredible. This package is a real street fighter.

(I played with some Ai for the post pics, tell me what you think, also video is in our story)

We are taking a big step here in 2026. This is the future home of Case House Performance & RKtuning & Case House Machine, today everything is official. As of now we will be moving around mid July and we are still working out details and the logistics as far as that. But yes it is definitely happening.

Thank you to all of our awesome customers over the years and everyone who believed in us to make this possible. We will be sure to keep everyone in the loop as things happen.

Some shots of trying to do some work on Saturday. Temps were amazing, great race day.

If you weren't fortunate enough to see us at Cars and Coffee last Sunday, you missed this badass beast. Joshs TT C8. It got more attention than our 2k hp C6Z shop car 🙁. Thats ok though this is absolutely awesome. We went with a TT kit. Everything else in the drivetrain is still the same. Upgraded DCT clutches, Gforce axles, built 416 motor and plenty of fuel to support over 1000hp.

For now we had a change of direction with the port system and that is what we are currently waiting on. We will post again when this car is fully tuned and announce the port system we are changing to. For now if your in the ocean county area you may see Josh driving it around as it makes all the blood pumping turbo noises.
