Car will be perfectly reliable at 350bhp. They say the cars limits for the engine are at around 450bhp although there are always some people that run all day long above that and others that suffer just below that but the general rule of thumb is 450 is the safe power level.
350BHP:
3" Exhaust System Fully Decatted
Green Panel Filter
Remap e.g. Dynamix
NGK PFR 7B Spark Plugs
Should make around the 350bhp mark.
The VF35 is at its limit when you get to 340-350bhp so if you want to go the next level you will need a better turbo and then the price racks up.
400BHP:
3" Exhaust System Fully Decatted
GT Spec2 Headers (Heatwrapped or ceramic coated)
Flow matched up pipe.
***Doing the above mods will lose the scooby burble on full throttle and sound more like an angry wasp due to the headers being more or less equal length***
Turbo: MD321H
650cc Injectors
Perrin Induction Kit
Remap e.g. Dynamix
NGK PFR 7B Spark Plugs
Exidgy Uprated Clutch
That will be around 400bhp and great for the road.
If you are tracking the car or using it flat out all the time you would want a fmic which can cost around 400-500 through to up to 2000 depending on quality and size.
For reliability some people put in better oil pumps, fuel rails, fuel pressure regulators etc but they are not essential to get the power levels you are after.
As always with modding, if you do it bit by bit or on the cheap it will always cost you more in the long run.
