To sum it up… There are enough Monkeys” out there selling “High Performance” engine kits. These swindlers simply slap a cheap, Chinese knock-off head on a stock engine (sometimes a few other shoddy parts) and add a few numbers and letters to the engine’s name. Then they post some ridiculous horsepower claim and overcharge you – laughing all the way to the bank with your hard-earned money.Performance enhanced GT5 model, for a more durable, powerful engine!
