You’re right. Any inline 6 engines i’ve seen are dogs. The only way Ive seen them make any impressive horsepower is with a turbo(s). Take a bmw for examply. Inline 6, rwd, and for the most part…not very impressive in bone stock form. Even with bolt ons, they are still pigs and wont compare to an LS1. But turbocharge that bmw, and its a solid performer. Cast iron block, aluminum head, its a good platform for some real timeslips.
