Eric Hsu’s Beyond the Dyno With Genesis Information
Eric Hsu has posted some relavent information about the 2.0T motor and the driveline of the Genesis Coupe. He recently spoke to Gary at Design Craft and picked up some very useful information to dispel the rumors around the car. Among the information – the coupe uses a gear type (helical) rear LSD, not a clutch type. He also mentions differences between the Mitsubishi 4B11 block and Hyundai’s Theta block. Remember, we made the mistake saying they were the same when in fact, they are not. Make sure to see the edits we made in our article here. To clarify, Hyundai designed the engine as a member of the World Engine Alliance. They then shared the design with other members Mitubishi and Chrysler, who modified the design to their applications. So while the designs are similar, they are not the same. Eric also points out the issue with the camshafts on our page here – that it is difficult to see if cams are identical just from photos. We agree, but we’re just posting what we see and read online. To see the rest of the information, including aftermarket turbo fittment, click here.
I have read here and there where people are claiming that the Mitsubishi and Hyundai versions of the 4B engines are nearly the same. So to clarify, here are some factual things I’ve learned from talking to Gary at Design Craft (who would probably be the leading Hyundai 4B11T expert at this point in time), Simon at Hyundai (who is a Hyundai test engineer and probably knows the most about the Genesis Coupe at this point in time), and Mo at Mitsubishi (who just knows a lot about both versions of the 4B11T and a certified car nut himself) about the Hyundai Genesis Coupe and it’s engines:
