its prolly already been said but the 4g63t is the strongest four cylinder ever made...mitsubishi has been makeing the fastest 4 cylinders since they hit the US in 82...the only 4 cylinder thats block head all internals are rated to well over 500 horsepower...name another 4 banger that can make that power with just bolt ons no nitris... by the way the fastest 4g63t runs an 6 and i considered at this time the fastest 4 cylinder on pump gas
