Both the GSX and GS-T have 210 stock crank HP. Yes with all your bolt on's 220's 230's on stock turbo to the wheels. The stock turbo is truly a JK and only good for about 270 crank hp. This is what I am pushing and running low 14's. 14.0-14.3 If you priced a turbo upgrade for a GS-T and it was 2k you went wayyy over board. You can have a small 16G turbo and install kit for right at 1k. This will bump wheel hp up to around 300 on pump 18psi. 315-320 or so on race gas with about 22psi, and put you in low 13's high 12's catagory (FWD), depending on traction. For 2k you can get a 20G with an external gate and push some really nice poines. All of this with stock bottom end. With a Small 16G you can still run the stock injectors, but you will need an upgraded fuel pump. I would advise to get larger injectors however, but it's not a must. Tom Hoppe Ran 11.92 on stock injectors and side mount with a small 16G (AWD). For the record I wouldn't trade my GST for a non turbo any day. No offense to anyone, just saying I wouldn't. And I don't know anyone with a FWD that has had tranny problems some of the AWD's experience tranny problems but 80% are caused from abuse. It's expected to some extent that your gonna break tranny's you try launching at 4500 and droping the clutch with about 300+ to the wheels all grabbing for traction and see how long your tranny lasts. Good Luck in your quest for more power.
