Our Stage 4 motor is a total workhorse. Our engine program has been proven time and time again on and off the track. We have countless race hours on these engines as well as millions of street miles that prove you can have the best of both worlds. We balance and blueprint everything in these engines. We balance and blueprint everything in these engines. Each piston is within ½ gram of each other, the rods are within ½ gram of each other on both the big end and the total weight. Each crank is sent off for balancing and comes in less than 1 gram. The only difference between our stage 2 engine and our stage 4 engines are the internal parts. The time and resources spent on perfecting the clearances and balancing the rotating assembly is done on all of our engines.
