yes after some development has been done qr will be very strong, but I do not believe it will happen over night. Remember the sr20 has been around about 10+ years and qr25 is in its second year of production. The qr25 will not be as strong as the sr20 with out alot of money and work, and then it may still not measure up. the sr20 is one bad 4banger

The QR was designed to be a normally aspirated motor with less friction, so there is a lot of potential for much more power. Even keeping it normally aspirated. It will never be as strong as a SR stock to stock. Any motor can be made strong to handle boost though.
