New to me 2002 Subaru WRX.. advice wanted!
Hey all, new to the whole turbo'd gas engine.. built a couple old mechanical Cummins so I understand a bit about fuel/air and turbos, but I'm not gonna pretend this car don't stump me because of the computer controlled stuff.
Anyway, I picked up a 2002 Subaru WRX, 165,000 miles with a 5 speed stick shift. Came with a 3 owner carfax, very very clean, and a stack of receipts from all maintenance and work done by the dealer. Car seems in very good condition, I've been driving it about 500 miles and haven't had a problem. Previous owner had dealer replace clutch, turbo, cat, axles, brakes, valve cover gaskets, water pump, radiator hoses and lines, and other stuff about 10k miles ago.
I recently replaced front/rear diff, transmission/transfer case, and engine oils so I know where I stand. No check engine lights, passed inspection easy.
This leads me to the reason I'm posting. Been doing some reading on here, so I figured I'd make an account to ask some questions. The previous owner let his son drive the car for all of a month before I got it, and in those 29 days a Fujita short ram intake and GReddy BOV made their way onto the car.. other than that it is ALL OEM parts. The first thing I had to do was soften the BOV as it wasn't opening, and forcing the air backwards causing turbo flutter. It is set up VTA, I at least have it adjusted where its working properly now. These two upgrades seem to be way out-of-order from what I've read. Is it safe to leave them on? Should I find stock parts and put them back on? This is my DD going to work, school, toting the wife and 3 kids around.. been there done that with go-fasters, I just want a nice reliable fun ride. The only thing I actually want on the car is exhaust, which I just ordered CNT V2 catback after reading some good reviews.. hope its quality.
Sorry for the long post, just getting that background info in and hopefully everything you need to know to get me an answer. Thanks in advance
