/Rotary Extreme Custom Turbo Kits/
Are all turbo kits the same? You bet they aren't. While there are cheaper custom turbo kits on the market, most of them cut down the cost by using substandard components such as unknown wastegate and turbo manifold which you can purchase on Ebay for merely $100. The flanges and clamps they use are also cheaper quality. If those components fail, you can expect a disaster which will cost thousands of dollars to fix. If the wastegate fails, the wastegate valve will not open and the boost will spike to 30+ psi! You can expect a blown engine resulted from that. If the turbo manifold cracks, the hot exhaust might cause engine fire! Our custom turbo kits only use the highest quality components available on the market such as parts from Garrett, HKS, Tial, Aeroquip, and Earl's. Our philosophy is doing it right the first time and we also believe 3rd Gen RX-7 deserves the highest quality products.
