I hate always seeing peeps on the board thinking cuz you can run 10psi of boost on the HRC kit you can do it as well on the Star kit and make the same power and all the fuel setting will be the same! There are some differences between the two turbo's that most everyone seems to over look. First of all they are two totally different size turbo's. A S16G Flows say 575cfm, a S20G flows 680cfm, and a T3-T4 Flows say 785cfm. Can you see the size difference?? Now if you take two of the idenical engine setups and throw 10psi of boost with the S16G at one and 10psi from a T3-T4 at the other, your gonna see two totally different HP curves and peak numbers. Just for instance a T3-T4 with 10psi on the dyno may make 250FWHP and a S16G with 10psi may make around say 200FWHP(that's a 50HP difference at the SAME boost level!). so with that in mind both turbo's make totally different power at the same boost levels. Like a T3-T4 can make More power on pump gas then a S16g or even a S20G, the reason a T3-T4 can make more power on pump gas than is S16g or even a S20g is because the T3-T4 has less backpressure, less heat which gives lower egt's and less detonation. So to some people that makes the T3-T4 the turbo of choice.....it's still a very streetable turbo and makes good clean power. So these are just a few words of wisdom for those of you who think that you have to match boost levels between the two kits to make the same power. Does my babbling on make sense to anyone?

P.S. some of these #'s I gave may not be exact, there pretty much just examples and if anyone has anything else to add or say, do it up ;-)
