This is for sale in the US now. Installation time is 2 days and does not require an engine out, just a lift.
The car is/has been running stock internals on 13psi of boost for the past 2-3 months. The car has been driven over 8000 miles with no detonation or clutch slip (on the stock clutch).
Dyno wise, the car is laying down 603whp at 13psi. At 6psi, the car made 475whp. The 0-60 times for the 6psi and 13psi are even (due to tire slip at 13psi) at 3.2-3.5 seconds.
See it in next months Modified L&E in the US and Motor Magazine in AU.
