I was driving angry and very fast in my 99 GTB, I didn't look at my tacho for corner was coming up fast, I still had my foot to the floor then felt the boost drop so looked down to see I was redlining. Once I slowed down I heard a loud knocking from the engine almost like valve was bashing piston on every stroke, it also has a seriously deep and loud howl as the primary turbo starts up that just gets louder as revs increase. The car is only just drivable but sounds like it will die at any moment. I have just started stripping the unnecessary stuff from the engine bay but will need to get serious  and take engine out soon. I need info and step by step instructions as I will be doing most of this myself, what good literature is out there??? If someone could point me in the right direction it would be most helpful. Thanks.
