Stronges inline 4 engine?
 

All motor, stock..and I said all motor. So if it comes stock with a super charger or turbo(s)..that doesn't count...I can only think of the K20a. Anyone know a stronger 'i4' engine?"porsche 968, had a 3.0L n/a 4cyl that made 240hp in the early 90's"interesting. But I mean like atleast 100hp per liter like the K20a does.2.2 L with 222hp

porsche 968, had a 3.0L n/a 4cyl that made 240hp in the early 90's
