want to make 300-350hp w/ carbed 2nd gen

Hey I have a street ported 2nd gen with Weber carbs 48dcoe. I was wondering what turbo i should go with to get around 300-350hp. My car is set up mainly for drifting if it helps making the decision. also if there is any companies out there that make kits for this? your help will be greatly appreciated.

BNR stage 2 can get around those power levels I believe.

Do your self a favor an go for a four barrel carb over the two barrel. It will make life much easier when it comes to to making the car acctually driveable.

The problem with the two barrel is that it has one fuel circuit that needs to operate in two very different "atmospheres". The first atmosphere being the one that you are breathing right now with 14.7psi (absolute) in the fuel bowl and then the full power atmosphere (14.7+boost). From my experience if you keep the boost below 8-10psi you can acctually make the carb work, and work pretty well, you may not like the gas mileage but it will work. With the four barrel you have an additional fuel circuit to work with in the tuning.
