Okay so I am looking at spending a decent amount of money on a modified fg xr6t. The guy has thrown 10k at it and apparently has all receipts and such. I was wondering if you guys could tell me if this is a safe build or if I am looking at having to do more to this car after I buy it (forged engine parts, etc). The guy says its making 380 kw at the wheels and over 500 hp. All mods were done at http://www.forcedperformancetuning.com/Ford-FG-upgrades.html
This is the build
Process West s2 I/C kit (includes fitting)
Process West muffler delete pipe.
Advanced headers 4in dump pipe assy.
1000cc Bosch injectors.
Modify factory airbox.
Xcal4 flash tuning device & custom 98 tune.
Gt3582 core (includes new core, profiling comp cores, actuator,gaskets, oil line & fitting)
Springs/headstuds.
Fuel pump module - E85 compatable.
If you guys could even tell me what things are looking at having to be upgraded around the 500hp mark?
