HKS Drag Supra (MKIII MA70 7MGTE) - Japanese Promo Video

[shaeff]

Not sure if it's a repost or not, if so, I'll just lock it down.

KS, Japan's premier performance products manufacturer, campaigned a drag racing version of Toyota's MKIII Supra in the early 1990's. The car featured a composite body over a Pro-Chassis RWD chassis, powered by an HKS tuned 7MGTE turbocharged and intercooled straight six. Producing around 800hp, the Supra posted high-seven-second 1/4-mile passes in Japan, and even visited the US for some demo runs and car shows.

I nabbed all of this info from a different forum. Info posted courtesy of Jeeves, Video from Webbracing.

n the RRC Drag race's top category "Pro Stock Class", there was a car with insane performance. It was the HKS 70 Supra. As a proof, in Aug 1991, RRC 3rd race, the car broke that 8 sec wall nobody was able to break before. It ran a 7.91!!

The engine was:
- 7M-G Twin Turbo
- Forged Pistons
- 272deg computer cam
- Special oversized valves & springs
- Rev limit: 8750rpm
- 826 hp (850 ps) at 20 psi (~1.4 bar)
