I am building my car from scratch. The box is actually a GT3 item from a cup race car and is effectivelly the strongest box from the 911 series (also used in the twin turbo and GT2). It also has the bonus of the fantastic porsche cable shift system.
The turbo's etc are new Getrag hybrids to my own spec as will be the rest of the twin turbo kit... the engine is actually ideal for turbocharging as it has an ideal 8.8:1cr as std and can take 15psi totally stock... 10psi gives well over 500ftlb without even opening the engine!
