Why buy our kit? It grows as your 240 does. No need for a larger intercooler or turbo. Just add our ECU, MAF, fuel system and boost controller, and instantly go to 300+ horsepower!
The turbo derives its power from exhaust gases spinning an impeller inside the exhaust housing. We all know this. Why would you want exhaust gases from different cylinders hitting the impeller blade at uneven intervals? This is inefficient. For the best performance, ALL exhaust gases should reach the turbo manifold's collector at equally spaced times, spooling the turbo up more rapidly.
