idk about a fail- it is good for 500whp on the factory block- their entire head was designed and manufactured by cosworth- it is an absolute torque monster- spooling on the stock turbos is effortless- and the power curve even on a set of tial 770r's or dual gt28RS's is still efficient and quick
its all the small shit on the car that fails that make it a pain
the issue is that people are buying a 50k car- modifying the shit out of it- and then complaining when shit brakes and they have to pay for parts for a $50k car
in all honesty I regret selling mine and once im done with school im buying another one
