with these engine upgrades id say the n/a's could easily make it to the mid 200hp range with no boost.
162whp is close to WRX power!! A 160+whp NA engine must fell very good!! A 200+whp NA will put a stupid smile on your face and leave it there!

300chp is a LOT of power!
It is good to know you guys are getting more power options every day... I'm was always a fan of NA engines! The best engines in the word are NA (IMHO)... GT3, Carrera GT, C63 AMG... I really hope to see some really fast NA Subarus!
