Sometimes I wonder, WHY? JUST WHY?

10/28/2026

Another Holleran's Performance customer car spotted in the wild at the Overcrest Productions rally. In 2023 this one was a no stone unturned full mechanical rebuild with lots of little unseen upgrades.

10/27/2026

A look back, at the Megan Young 2.8L engine & transmission build that's still running rally's like the Overcrest Productions and frequently carving up the back roads. Putting years of reliable miles & miles & smiles on customers faces for me is what it is all about.

Another 86 930 Turbo engine going together.

1968 911 S case was saved, after 40 grueling hours and nervousness this one's ready for final cleaning and assembly.

10/20/2026

1968 911-S engine case update.

6 sleeves made, 1 case half bored & squared up, 3 sleeves trimmed & pressed in. Now I'm working on the other half, then it has to be setup again, bored and surfaced back to the original dimensions on Porsches blueprint.

Lots of time.

Still have a long way to go.

WHAT DUU PUCK?

That Big Billet is on the way to being the perfect repair for a Porsche engine case.

10/10/2026

One of the most popular builds we do. A 3.2 liter short stroke just sings & is one of my faves.

The power band with a properly setup CIS injection system is very reliable, responsive and revvy. With bigger valves & some decent cams, a Crankfire ignition and other touches they just don't give up anything throughout a very full, broad and torque-y RPM range.

Out with a badly built 2.7 for this 1974 911, it really shines now that it has a new Holleran's Performance 3.2 liter bullet out back.
