I know very little about this turbo and would like some advice from the more enlightened users. I think I've seen these as Garrett and HKS variants (May be wrong) - is one of these better than the other? Also how much do these normally sell for in the UK? I've had a look at Nengun and the like but I'm more interested in a UK price. I've heard that they can flow up to 800bhp- once again, is this accurate? Lastly, the price I've seen is for the turbo only. As I have a twin set up at the moment, what else do I need to consider for the swap? (Manifolds, wastegates?) Sorry if this is all a bit kindergarten for some, but I did search and couldn't find a concise answer.
