BNR Turbo's? Should I get a stage 1 or 2
 
I was wondering if anyone has a stage 1 or stage 2 BNR turbo? How you like either one, and how the responce on the clipped turbine is? I had a 60-1 hybrid that was making 295rwhp. That turbo was way to big for me and at 10psi I was not even tapping into the power it could make. I drive in cali traffic and low responce and high power= me no fun for me.

So I want better responce, and decent power. Maybe 260rwhp.

Does anyone know if the stage 2 to4b is smaller than the to4 60-1? The reason I changed my turbo was becuase it didnt hold boost to redline. Died off really early to 6-7psi. Thanx for the help. :D

I think BNR stage 3 is a 60-1, stage 2 is a h3 wheel. Your boost bled off at redline probably because the stock exhuast wheel was choking the flow of air. Was the exhuast wheel clipped on the last turbo?

My last 60-1 was not bnr. It did have a 15 deg clip. My stock turbo was just stock.

Is a H3 wheel smaller than the 60-1. If so how much smaller? Would I get better lower end response with the stage 1 or 2? If anyone knows?

You have somthing else wrong. Likely the clip on the wheel, or a WG problem. I have a 60-1 compressor with a stock HT-18 exhaust side, no clip and I hit full boost by ~3k RPM's It bleeds off every so slightly after ~7k, but I rarely rev that high during normal driving anyways.

look on the turbonetics site, they have the measurements of the different wheels. A h-trim to4b is just under a 60-1. You might bet a little better response with a smaller wheel, but like rpeck said I'd be on the lookout for something else. I recall you put down like 290 rwhp with your hybrid, so it's making decent power. Bleeding down to 6-7 pounds doesn't sound right, check your wastegate.

No no no, my stock turbo died down to 6-7 psi. Theres nothing wrong with the 60-1 turbo. It made way more power than I expected and I need more fuel. It spools up at about 3K with full boost at 4K. Holds to redline and my power is still climing. I just want to know what has good response and what should I go with? A stage 1 or 2 BNR turbo. So anyone with either turbo, if you could let me know how you like it. I would be very happy at about 260rwhp. I just dont need 300rwhp in a car I drive to school everyday.

I changed my stocker to the TO4! Sorry about the misunderstanding! My stock turbo, like all turbo's lost power after about 5K to 6-7 psi.
