Half-Bridge + Stock turbo?
I'm currently building up my arctic silver S4. It is originally N/A but I'm rebuilding it with the stock S5 turbo and manifold. Now, I could only find 1 thread on this and it wasnt very helpful so I am wondering is this possible? I mostly want the sound from the bridge but I only want around 200-250 horse and am aware a bridge is very overkill for this. Thank you for any responses

Call pineapple racing.
They’ll tell you to go with a streetport to get the overlap which will give you some brap brap, but still maintain low end drivability, and work with smaller turbos. They also sell the porting templates.
I thought the same as you ~10 years ago, except I was going to go with a big turbo for the bridgeport. I called pineapple racing and they talked me into a streetport. Ran on a stock turbo for a bit and have since been running on a panspeed hybrid turbo (similar to bnr stage 3), and it’s a fun peppy street machine.
In the end, it’s your car and your money, so do whatever you want. I just recommend building a system which will work together to give you the best outcome. Stock turbo will just be blowing hot air when combined with a bridge, nowhere near ideal. Possibly even a risk to blowing the motor with hot IAT’s…?

the overlap the bridge port adds makes it more sensitive to backpressure, and then the stock turbo has lots of backpressure, so its kind of a loose loose.
