The World’s First Twin-Turbo Diesel Ferrari Finally Makes Boost!

We followed the initial teardown and engine swap of this wild project during its first phase, and now the so-called Diesel Ferrari returns to the garage for a custom exhaust. The Grind Hard Plumbing Co. crew recently dropped a massive V10 twin-turbo diesel powerplant into a salvaged 355 chassis. Track enthusiasts watched them cram the motor into the Italian engine bay. Now, the builders fabricate the required plumbing.

Sorting The Diesel Ferrari’s Wiring

Starting the daily grind, the team focuses heavily on removing excess electrical lines. A massive pile of unnecessary wires left over from the original Volkswagen donor vehicle litters the engine block. Ethan explained: “Figured I’d start out with a little bit of clean up on this wiring harness. I’m tired of having to detangle everything every time I need to do anything.” Stripping out the dead weight helps the crew route the main power cable directly toward the starter.

Building The Custom Exhaust

The fabricators turn their attention to the metalwork, dragging the old Touareg stainless tubing onto the shop floor. Ethan stated: “Today I’m going to build a custom exhaust for this Ferrari. and then we’ll hook up the cooling system, hear what it sounds like with a custom exhaust.” To save valuable fabrication time, they cut the original flanges directly off the old downpipes. Welding a cross-pipe over the transmission forces the exhaust pulses from both cylinder banks to merge together.

Firing Up The V10

Connecting a diagnostic scanner to the fresh wiring proves annoying at first. Eventually, the tool reads the computer data accurately and ignores the missing glow plug codes. Hitting the ignition switch sends the Italian hybrid roaring to life. The engine revs incredibly fast all the way to 4,500 rpm. Unlike a traditional heavy-duty truck block, this dual-overhead-cam setup spools instantly upon hitting the throttle. Ethan pointed out: “Yeah, that’s because both of these turbos could fit sideways inside of a Cummins turbo.”

Preparing For The Next Phase

Hearing the engine roar through a proper exhaust pipe changes the vibe inside the shop. The build team currently waits for a specialized machine shop to finish cutting a custom component. The mechanics rely on a local machinist located in Spokane to fabricate the required clutch adapter. Getting this part built regionally keeps the project moving forward without major shipping delays. Once that single item arrives, the crew plans to take this Diesel Ferrari out for a rough test drive.
