Hey, I've been doing some research/lurking here for the past month and I have zero experience with modding a car. I would just like to clarify if this statement means that you can go from a completely stock frs/brz and add a turbo kit onto it without any other modifications? I tried to use the search function, but I couldn't find anything that I was looking for(may have been incorrectly searching). Thanks!

This thread is about naturally aspirated basic mods.
Their is a forced induction thread that should provide answers.
But quick and dirty answer
Yes you can bolt on a supercharger or turbocharger kit to a stock frs\brz motor without decompressing or other internal engine mods
On petrol you will be limited to about 10 psi boost due to limitations of stock fuel injection system. arround 280 wheel hp
You might also want to budget for a clutch and an oil cooler and a bigger radiator if you want to drive it hard or track it.
Without clutch you might want to stick to about 7 or so psi boost arround 240 wheel hp and you might get away without the radiator , but an oil cooler is still needed, unless you live in cold climate and you only drive hard for very short periods
stock cars are about 170 wheel hp
You can break stock cars by driving them like a d1ck, you will break a boosted one faster if you drive in that manner with no respect for the extra mechanical stresses and heat loading you are putting on the car.
