This. Any time you go modifying a car you're setting it up to fail. People that slap on new trubos, turbo backs, etc without proper tunes WILL fuck your car. I had mine all done professionally and even then you're still taking a risk.
About the fluids though, I always ran German Castrol in mine. Not sure what you mean by them being picky with fluids :D
Yeah same here German Castrol, but I've heard so many horror stories from Mobil 1 and other synthetics that end in spun rods. And Maybe I'm just picky because I have an 02 WRX with stock gears, so I have to pick my transmission fluids carefully.
if you KNOW how tot ake care of it yes i dont know if the OP knows how to if so he can research only problem i had with the STI was insurance and payments it was going to be like payhing for 2 cars...also depending how old you are.
im not favoring anyone of these i just looked at some downs sides for both inorder for me to find a choice.
i was going to return to the choice of an STI but decided to buy my uncles ISF instead which maybe traded in for another car soon.
My girlfrind has the wrx hatchback which is no STI but is still a great car none the less
Haha of course I'm not taking it personal. Being a Subie owner, he should just hear about the car from people that actually own it.
