The are both built to handle up to 18 psi stock
But with a 16g at 15psi you will hit the fuel cut. The simple solution to that is injectors and pump. With that setup boosting 20 psi and a little tuning in a gst you are looking at about 350 to the wheels. The gst only has a 15% drivtrain loss compared to the gsx's with somthing like a 30% drivtrain loss.
dsm's are hp mules but the car is heavy as hell so you would get alot more out af a 350hp sr than out of a 350hp 4g63.
the second gens actually get 12 psi stock to the intake manifold on the t25. This is although they run 14, but the 2nd gen BOV leaks back to 12. One reason why every second gen owner has a first gen or greddy bov. The first gens run 10.5 stock on the 14b. As far as fuel cut goes. Depending on how many intercooler and vacum leaks you have it can cut anywhere. But if everything is tight. A second gen MAFS will not cut untill 22psi on any turbo that can flow 22psi (big 16g, 20g, what ever). The first gens have a ****tier mafs and will cut at boost levels around 18-20 psi. many people switch to the second gen mafs or get moddified mass. To really get rid of fuel cut, either a fcd is needed, a vpc, or stand alone that converts a mas setup into a speed density setup.
