In October 1985, Toyota added the 1G-GTEU to the X70 Mark II lineup. It was the first production DOHC four-valve-per-cylinder twin turbocharged inline-six engine in Japan, developed in collaboration with Yamaha Motor, who engineered the cylinder head and valve train. Two CT12 ceramic-bladed turbochargers fed through a water-to-air intercooler. Output in original specification was 185 PS at 6,200 rpm and 173 lb-ft at 3,200 rpm. Later revisions with an air-to-air intercooler raised output to 210 PS. This car, produced in 1986, sits within the production window where either specification is possible depending on the exact build date. The significance of this engine in 1985 cannot be overstated. Toyota and Yamaha had produced twin-cam engines before. They had produced turbocharged engines before. Combining four valves per cylinder with twin turbochargers in a production sedan, in 1985, was something else entirely. This was the engineering foundation that made the 1JZ-GTE possible. The 1G-GTEU proved the concept worked in a real car driven by real people every day. This is the GT trim hardtop, which means pillarless frameless windows across all four doors. The burgundy velour OEM sport seats are in the condition that comes from a car that has been cared for. Ceramic tint all around. HKS turbo timer keeps oil circulating through the turbochargers after shutdown, protecting them from heat soak. Cruise control. Air purifier. CarPlay installed with the original radio retained and included. Cold A/C. New Goodyear tires. 56,740 miles (91,301 km) on a 1986 car that has been in one careful owner’s collection. Less than 10,000 km added this year. Used, maintained, and kept. Mileage: 56,740 miles (91,301 km). Interesting Facts The 1G-GTEU was developed jointly by Toyota and Yamaha Motor, with Yamaha engineering the DOHC cylinder head and valve train. This was the same partnership that produced the 4A-GE and later contributed to the 2JZ-GE. Toyota provided the block and overall engine architecture; Yamaha provided the performance-oriented top end. The result was Japan’s first production twin turbocharged DOHC four-valve inline-six. The 1G-GTEU used two CT12 ceramic-bladed turbochargers, one feeding each bank of three cylinders. This parallel twin-turbo configuration minimized lag compared to a single large turbocharger and allowed the engine to build boost earlier in the RPM range. The ceramic turbine wheels were chosen for their low inertia and fast spool-up, though they are known to be fragile at extreme boost levels. The X70 Mark II, Chaser, and Cresta were the first Japanese production sedans to offer a DOHC twin turbocharged engine as a factory option. The GX71 chassis was shared across all three nameplates, which were sold through different Toyota dealer networks in Japan. The Mark II went through Toyota Corolla stores, the Chaser through Toyota Auto stores, and the Cresta through Toyota Vista stores, giving each car a distinct dealer identity despite sharing the same platform and engine. The 1G-GTEU directly preceded the 1JZ-GTE in Toyota’s performance engine lineage. The lessons learned from twin-turbo DOHC packaging, intercooling, and turbocharger sizing on the 1G-GTEU were applied directly to the development of the 1JZ-GTE, which arrived in 1990 with improved output and better driveability. The GX71 is where that engineering story started in a production sedan. About Us We’ve been working with Japanese vehicles for over 25 years. Long before opening our location in the United States, our team was importing and servicing these vehicles in Europe when many of them were still new. Because of that experience, we know these platforms extremely well. Every model has its own weak points, and we inspect and address them before the vehicle is offered for sale. All vehicles are serviced at our facility in Japan before shipping. Fluids, belts, filters, batteries, and common failure points are inspected and replaced when necessary. Unlike many dealerships, we actually drive our vehicles. They don’t sit in a parking lot. Our trucks and cars are used regularly so we can verify reliability before they reach their new owner. When you buy from us, you’re getting a vehicle that is fully prepared and ready to drive from day one. JP-TRADE is our first location in the United States, supported by a team of more than 40 people across Europe, Japan, Korea, China, and the U.S. If you made it this far, here is a little bonus for you. Why did Toyota need Yamaha to build this engine? By the early 1980s, Toyota was the largest automaker in Japan and one of the largest in the world. They had the resources to develop any engine they wanted. They still called Yamaha. The reason was expertise: Yamaha’s motorsport division had spent decades engineering high-revving, multi-valve cylinder heads for racing applications. Toyota’s strength was production engineering, reliability, and scale. Yamaha’s strength was performance head design. The partnership worked because each side brought something the other lacked. The 1G-GTEU head was Yamaha’s work on Toyota’s block. The result was an engine that neither company could have produced as quickly or as well on their own. Toyota continued this arrangement for decades, applying the same logic to the 4A-GE and elements of the 2JZ-GE.
