You’ve never seen a custom 1974 DJ5 Mail truck like this one, and you might never see it again.

This was probably the most commanding and popular car at San Fransisco.

900hp from an S58? Here's exactly how we would do it 👇 READ BELOW
The S58 is already one of the most capable inline-six engines BMW has ever produced.
473 to 503 horsepower from the factory. Twin-turbocharged, high-revving, and built with serious intent. But if you think that's the ceiling, you haven't seen what this platform is actually capable of.

Here's the full build breakdown:

FUELING UPGRADE
This is where it starts. Brands like , , and make sure your S58 can actually feed the power you're asking for. No fuel, no fun.

COLD AIR INTAKE
Give the turbos what they want. , , and are the names here. Denser, colder air in means more combustion, more power out.

TWIN TURBO UPGRADE
This is the heart of the build. , , and Comp Turbo all make hardware that takes the S58 well beyond its factory limits. Pick your power level and build accordingly.

EXHAUST SYSTEM & DOWNPIPES
, , and give this engine the soundtrack and flow it deserves. Proper downpipes unlock the turbo potential you just installed.

HEAT EXCHANGER
Power generates heat. Heat kills power. Upgraded heat exchangers from DO88, , and keep temps in check so the rest of your build actually performs.

ECU UNLOCK & TUNE
None of this works without it. An ECU unlock and proper tune is what ties the entire build together and makes sure every component is working in sync.

The S58 starts at 473hp from the factory. A build like this puts you within reach of 900. That's nearly double the horsepower on a platform already built for performance.

So tell us 👇 would you rather build an S58 or a B58?
