Mazda,
What you had done is FDE's base spec. Phil generally quotes them good for 800hp.
He will also do similar specs to what jet is talking about and the price goes up accordingly.
Many moons ago /thurple ute auto to manual conversion time) I had my driveshaft shortened by VEEM here in Perth. They are known locally as Very Expensive Engineering Mistakes.
Drove the car home on the high at 110kmh and parked it. Moved it the next day to wash it and found a centre cv bolt sitting in the carport.
Jacked it up and found the remaining 5 all loose.
