Why the Hitachi 2 Gargantas is "Exclusive"

The term exclusive in this context refers to two things. First, the Hitachi two-barrel design was exclusive to specific OEM partnerships (Nissan, Isuzu, Mazda, and some Ford/Mercury captive imports). Unlike the ubiquitous Holley or Weber, you cannot find this carburetor at a generic auto parts store. Second, the factory documentation (the manual carburador Hitachi) is exclusive—often rare, out of print, and hoarded by veteran mechanics.

Common models covered by this guide include: Why the Hitachi 2 Gargantas is "Exclusive" The

• Hitachi DCP 306 (Nissan Sentra/Datsun 210)
• Hitachi DFR 338 (Isuzu Trooper/Pickup)
• Hitachi DCH 340 (Toyota Corolla/Tercel)

Why You Should Keep the Hitachi (Don't Swap to Weber)

Many forums will tell you to "throw the Hitachi in the trash and install a Weber 32/36." While the Weber is simpler, it is rarely better for these reasons:

• Fuel economy: The Hitachi, when tuned correctly, gets 25-30 MPG. The Weber drops to 18-22 MPG.
• Cold start: The Hitachi’s complex choke system works perfectly. The Weber manual choke is a hassle.
• Smog legality: Swapping carbs is illegal in California and many EU countries. The Hitachi retains EGR and charcoal canister connections.
• Authenticity: A clean, rebuilt Hitachi with a factory manual adds value to a restoration. A Weber screams "I gave up."

That said, if your throttle shaft bores are worn (wobbling shaft = unrepairable vacuum leak), you have no choice but to replace the carburetor. In that case, find a used Hitachi core or buy a rebuilt unit from National Carburetors or Guaranteed Carburetors.
