603 how much reliable HP?
how much horsepower and torque could a 603 be built to be reliable?
i was thinking of using some kind of variable turbo or twins and building a header to get it to fit. could you get 250 hp out of it and 3-350 tq?
Just brainstorming right know sold my 300td wagon and bought a 87 300sdl with a 603 in it but i also have this 2.2 5 speed 190 that needs a motor
Reliable is a relative term. Simpler tends to be more reliable. Also, more power leads to more wear and shorter overall life but not always less reliability.
A good variable vane/nozzle turbo, improved intake, exhaust and 6mm pump elements should be able to easily achieve your 250HP goal.
300hp is a common figure for stock internals. However, an engine with a Holset making 300hp at 4500rpm will be less stressed and live longer than one with a VNT making 300hp at 3000rpm.
Its all about torque, thats what makes it fun.
