my gs-t seems that it has a lot of shit wrong......

my gs-t seems like it has a lot of shit wrong with it idk where to start... it seems i have an oil leak somewhere or i have a blown head gasket bc everytime i'm done taking it for a ride and let the turbo time run there is smoke coming out the hood so i poped the hood and there is oil i guess all over the exaust manifold cover... next thing is friday i went for a ride and came back and i walked out of my house and i saw a puddle of anti freese under my car... well my friend came over and we were looking over my motor and we noticed that the tank that the anit freese goes in was full and that is where it all was comin from and i was empty on anti freese so we had to fill that back up... i have an alarm and it seems like everytime i set the bitch it goes off like 5 mins after so its like i can't lock my car lmao... i already put a new tranny and a new clutch in it.. when i was running my boost gauge power and ground into the radio it didn't work and now my radio doesn't work at all??? already spent $9,100 on the freaking car already... i don't want to get rid of it bc i plann on doin a lot of nice stuff to this car but it seems like it has tons of problems... it already has a greddy type-s bov, hks intake, exaust, turbo time, autometer phantom boost gauge, r-tech 17", cooper zeon tires, eibach adjustable coilovers... So if anybody wants to give me some advice on some of this crap i just told you about plz go ahead and feel free to!!!

It sounds like the car was driven too hard by the previous owner(s). Maybe you should try a rebuild before you start upgrading parts.
