bnr stage 2 or 3
 
Right now I have something similar to bnr stage 2 turbo. I dont the exact to4e or to4b intake side I have, but it was pretty fun at first. Im am debating if I should bore out the intake housing a little more to make my turbo similar to the bnr stage 3.

How much more lag does the stage 3 have?

I would like more top end power, but I would like a smooth powerband also

I already have the fuel requirements, and I need a tune when my car is up and running again. I am taking machine shop and I might just do the modifications myself for the 60-1 compressor wheel to fit.

dude if you are going to go with the 60-1 wheel IMO you've outgrown hybrids. Even with the bored out stock hotside you are really choking down that turbo. Better off getting a full T4 60-1 (T04S front cover preferably with a divided hotside). I have a T04S .70 A/R compressor 60-1, undivided .96 P trim hotside and it will hold 20psi to redline (which is getting out of its efficiency, I'd say it's relatively efficient up to 18psi). On a stage 4 it will hold probably 14. and make 360-370 on a 13bt at max (the 400 number reported was on an RE I think), many people get a little less depending on porting etc. Save your money and go all out.

Good advice. I was really tempted earlier because I am taking machine shop class right now. So the only extra cost would b buying the bigger compressor wheel.

Im really low on cash right now and I dont need anymore setbacks. Sorry I was just getting a little excited there
