How much horsepower can a make reliably for highway use? I was thinking of a dual turbo set-up and some pump and injector improvements. I am looking at building a hot shot type rig and using at least a double overdrive for fuel mileage and still be able to run the speed limit up hill loaded. I see several Dodges and Fords with chips and other mods and got to wondering, why not one of these? If you choose to increase much more than that you will start to have some reliability issues.

Likewise, the HEUI injection system was first introduced for , although these engines coexisted with mechanically injected engines for several years. For , a twin sequential turbocharger system was employed for further improvements in throttle response, overall performance, and reduced emissions. All engines and prior featured a standard fixed geometry turbocharger. Early engines featured a 2 valve per cylinder head design, while HEUI models were upgraded to a 4 valve per cylinder head design for favorable airflow characteristics.
