The phrase that unequivocally resonates throughout the universe is "There's no such thing as a free lunch". Unbeknownst to the rest of existence, there is one glaring exception to this rule: The Mark III Toyota Supra. However, it does have one major drawback, which I will kindly explain how to fix, for good.aThe Toyota Supra MK3 Turbo is a bit of an oddity. It's a well-constructed, good looking and great sounding Japanese rear-wheel drive sports coupe that has stellar handling and more than adequate power delivery in stock form. It's popular with the drift and drag racing crowds, yet they're still available dirt cheap, unlike its successor
 Its 3.0 liter 7M-GTE engine, with the help of a single CT-26 turbocharger, pumped out around 232 horsepower and 240 lb-ft of torque, which for the late 80s and early 90s, was plenty. With choice mods, the iron block and aluminum head of the over-engineered engine could withstand an output of more than 500 horsepower without changing any major internal components. It's a true performance bargain, for scrap prices

Ladies and gentlemen, this is what's known in the industry as a show-stopper. This is a blown head gasket, an all-too common problem with the Toyota Supra MK3 Turbo, and the reason why is not because it was made with inferior materials or designed improperly, it was due to a torque spec error from the factory. The head bolts, from the factory are tightened to a specific torque. That value was less than what the engine actually required, leading to a "when and not if" situation of head gasket failure, especially when the engine was boosted past its stock limits.
