2G Swapping out a T25 for a 16G

[Nguyen13]

Question but the stock engine that the t25 has if you put 16g in what is the difference affects something?

I think this post by @gofer might help with that. I certainly couldn’t write it better myself.

Stick a J-pipe in there somewhere, cause you cant just go from t25 to 16g on a 2g.

The things about it is boost pressure is not the same across all turbos. Pressure is a function of flowrate. What we're interested in is the mass of air entering the motor. Simply put a 16g flows more mass at the same boost pressure as a t25. You have a lot of different parameters that affect how a car drives. How quickly it spools. What RPM range etc.
