The problem with putting new turbos on though is the lag. I really dont want extra lag.
If upgrading to say 600-700bhp then the lag would not matter too much. But say i now have 425bhp, and i change the turbos, run a bit more boost and get 500bhp with HKS turbos, the lag will affect my performance to the point that my 100-150mph time may be much quicker, but in normal driving my 0-100 will hardly change. And my reaction time when i slam my foot to the floor will drop significantly.
And replacing the turbos is a big spend for a very small amount of power. (unless i want to change my injectors, head gasket, etc.. etc..)
I guess what I want is increased performance as opposed to absolute power.
