What turbo kits are you guys running on this motor? I wanna turbo my gsr but i dont know which kit to go with. There are so many to choose from. And i want it to be a daily driver with 200-275hp on stock internals.

 

Ive seen 340+whp on a stock GSR daily drivin. Full race, Peak boost, fast turbo, Drag, like you say there are A LOT. for 200whp you would almost be wasting your money, If I had a Gsr and was going to boost it I would shoot for 300whp which is still reliable.
but anyway, for around ~275+ you could piece a kit together and tune with crome and make that amount of hp and easily daily drive it. if you have access to a welder or anyone who can fabricate I suggest making your own piping and buying a new turbo and just going from there.

Peak boost has a really nice kit.
