If you are going competitive/time trial, then NA is best. meaning... it will be more reliable.

If you want it for occasional track use, HPDEs, etc. then you can go FI you just need to concentrate on having every cooling mod imaginable.

This is a thread I started not too long ago.
Supercharger for Occasional Track Use?

One thing that bothered me most about a turbo setup is the NON-linear way in which power is delivered.

I prefer a linear response to throttle input, which is more likened to a supercharger than a turbo setup.

Thats all about turbo sizing and tune though, you can make a turbo car very responsive if you dont care about huge horsepower numbers.

Check your sanctioning body class rules .... Here in OZ, you can only "race" a car in its original OEM guise, you cannot add a turbo or S/C where not originally fitted by the OEM.

FI in either form puts a "lot" more heat into the engine and ancillaries and managing heat rejection is crucial to engine life and overall reliability.

Until you are able to drive your car no quicker in basic format, then leave it stock - there is a lot more laptime in the driver first, and then think about suspension and brakes before you need to think about more torque, and the cost of finding lap-time rapidly escalates.

Figure on HPDE training days to get the first 5 seconds of lap time, then maybe 2-4K for suspension to get the next 2-4 seconds, the same again to improve the brakes (pads, cooling, specialist rotors etc) for maybe 1-2 seconds, then $2k to add a diff centre for another second, then $4-6K to add 2, 3 or 4-way adjustable shocks for another second or two, and thereafter, each second will cost $10K or more (built engine, improved cooling, FI if rules permit, sequential gearbox, non-OEM engine management, data logging yada yada).
