This is the same reason people build Hondas:burnout:
The car scene is much different now than when the SVO came out. Muscle cars with over 400 hp is the norm...much more with simple bolt ons. A turbo 4 cylinder in a 3500 lb chassis will not be competitive with a 450+ hp V8 in a 3600 lb chassis.
Not stock for stock, it also would probably be more expensive to build the 2.3 but I would still like to see one at Summit. You can't tell me you're one of those "No replacement for displacement" people.
