1. It's not ignorance... it's experience.
2. You don't have to build an engine to run 400rwkw capable turbo's... simple as that.
3. How many full built engines don't last 1000km little own 5 years- A LOT!
4. I don't know the OP- I don't know his car or what he's going to do with it... I don't presume to tell him what he should or shouldnt have.
Why dose this have to turn into a built v stock, -5 v td... debate thread?
