Nissan had the OS Giken TC24 twin-cam conversion for its L-series motors. Toyota had its 151E 16-valver. Let’s not forget, however, that Mitsubishi had their own ridiculously expensive marvel of engineering, and it was built by none other than the famous Japanese tuning house HKS.
The HKS 134E was based on the 2.6-liter Astron G54B engine commonly found in everything from Plymouth Fire Arrows to Starion turbos. HKS de-stroked the stock motor to 2.3 liters, adding forged pistons and a twin-cam head of its own design. Fed by two Solex 50mm carbs, the result was an astounding 276 hp and 195 lb-ft of torque.
HKS’s original plan was for it to power the Starion D404, a rally car based on a production Starion but basically completely rebuilt to accommodate the custom engine and a 4WD system. The body was replaced with a composite shell of HKS’s own design, and a Pajero (Montero) transfer case was used to convert it from rear- to four-wheel drive. The completed car weighed just 2,028 pounds, some 88 lighter than Mitsubishi’s own Group B racer.
Some say that the twin-cam head was also used in stadium trucks as well. For more information about the HKS Starion D404, check out GroupBRally.com.
Guy down in Oregon has one of these heads. He did have a complete motor as well that was sold to Sakura in Puerto Rico. The motor is now in a Starion bodied drag car. There was also a women in the U.K. that had one of these in her street driven Starion.
The 151E was a 16 valve engine.
Thanks for the typo check. Noted.
I get all geeked out over one-off 4 valve stuff.
More porn like this, please.
does that thing have a lancer boxtype front end or?
Hello HKS, can you reproduce that motor? or maybe just the head?
Who would I contact to get one of these heads built
