Each state has different laws. Some are uncontrolled, others quite stringy.
People say California is pretty bad but really its not. A new car doesn't have to get a SMOG check (tail pipe emissions inspection) for like 6 years, and a used car only every 2 years. So you can run whatever exhaust or intake you want, then swap it for stock when you go for your SMOG test.
There are SOME rolling emissions trucks, but they are few and far between and easily avoided.
They only reason I run a stock exhaust (at least stock header/cat) at this point is cause I got tired of swapping and it didn't make enough of a difference anyway to matter.

My bet is the internals will be fine for N/A stuff. Crankshafts are a work of art in Subaru's and rarely need upgrading or modifying, but the rods are a guessing game at this point as are the pistons.

I'm betting that this engine is purposely choked from the factory. The GR and UR engines pick up anywhere from 20-30hp with basic bolt-ons. Granted, this doesn't have their displacement, but I'm sure 220hp is within the realm of possibility without that much effort.

Thats my guess too, about 220hp with bolt ons/tune, maybe more if the DI works better than expected.

And definitely this. It is a lack of development simply, no design constraint whatsoever. In fact, boxer engines ought to rev higher and harder than your run of the mill inline 4.
|
Highest I've seen is 8500-9000. There might be higher out there, but 8000+ is what the JDM STI's rev to.

I have no problem with this.
Honestly, this will be a GOOD car for the 1/4. I've seen early model Imprezas with WRX or STI swaps run 12's without any serious modifications to those motors (maybe a tune and an exhaust, but thats it).
With this car, I suspect a 400hp engine build and the low weight can get you into the low 11's, but with the even higher power engine builds out there the sky is the limit
