Welcome to the forums! going along with what scoobiescoodie said
1.Rotella T6 and also Amsoil European 5w40 are great.
2.I run the Cobb exhaust which has an awesome rumble and is a little easier to find. I would check out some videos on youtube though to get an idea of which you like most.
5. Forge BPVs have an awesome sound and are a little less expensive than the GFB. I bought my car with a VTA BOV and I can't wait to get rid of it, the ecu absolutely hates it.
God created turbo lag to give V8s a chance
