TORQUE KILLS ENGINES, our stock turbo on 20psi is more dangerous then a big turbo on 24psi (not precise numbers just making a point) With the larger turbo your going to allow the torque peak to build instead of the instant ramp up our stock turbo creates, our stock turbo kills our motor when over boosted because its so small. Running and MHI turbo or Dinan Big turbo is your best bet to run 23psi much safer. 23psi on these two turbos will be better on your internals while making more power because its a gradual torque build up.
I get special pricing on N20/6 Dinan Big turbo if anyones interested in a Group Buy, $1,100 Shipped straight from Dinan, straight Bolt on.

So on the same tune, say a PTF OTS map, the bigger turbo will be safe because it builds boost more gradually? Isn't it about the tune not the turbo? I understand that the size of the stock turbo makes it really peaky, but with an OTS map that's designed for the stock turbo, won't the power band be just as peaky?
