This Alfa Romeo GTV6 has undergone a preparation that will impress even the purists.

OktechOliver Körfgen, the name behind the company, is a German-based tuner/restorer specializing in Alfa Romeo Busso V6-powered models. We recently reported on his spectacular restorations on Alfa 75 and Montréal. This time it's an Alfetta GTV that's the talk of the town.

Italy's silver arrow

By mid-2025, the car was still being assembled, with preparation for the new "big bore" engine and disassembly for painting. By early 2026, the craftsmanship was complete: Oktech released photos of the Alfetta GTV6, christened the "Freccia Argento". This is the Italian counterpart to the "Silberpfeile" or "Silver Arrows" usually associated with German racing cars. The silver hue is obviously no stranger to the name given to an Alfa Romeo GTV6 that benefited from 27 months of hard work! 

Busso puts on muscle

Nicknamed the "bad boy", its centerpiece is of course its engine. A great deal of work has gone into the Busso V6, whose displacement has been increased to 3,897 cm³ . Power output has yet to be announced, but previous Busso preparations suggest that 350 to 400 hp and almost 500 Nm of torque will be available. As the icing on the cake, OkTech has already posted a few purrs on the networks, while we wait for the driving videos.

The intake has been modified, with simplified routing and modern silicone sleeves, improving flow, response and reliability. We also feature an aluminum performance radiator, with welded aluminum construction and superior thermal capacity to provide superior cooling. Hoses, wiring harnesses and other connectors are obviously nothing like the original parts.

Incredible finish

Once again, the work is absolutely remarkable. The photos of the underpinnings, the exhaust system and the engine show an astonishing quality of workmanship and finish. The stainless steel exhaust system is a thing of beauty. From an exterior point of view, the line is respected, but the Freccia is lower than the originals. No precise data available, but we're guessing 17-inch wheels and low-slung tires.

Inside, the Youngtimer ambience is total, with a magnificent Momo 3-spoke perforated steering wheel.

Other daring projects are just around the corner, as we've spotted another GTV being finished, all in black and nicknamed "Mad Max". Or perhaps "Pazzo Massimiliano"?
