Hi so i want to put a 6.1l in my 04 ram 1500 with 5.7l and so far am running minor mods programmer, full exhaust, pro charger intercooled kit(6-7 psi),85mm throttle body, throttle body spacer,and was wondering if anyone here has done this and knows what all extra needs to be changed for the bigger engine. like so far i've found out because their only on cars the crate engine doesnt have a pulley for a clutch fan so i have to change my fan over to electric.
Things like can i run my same ecu or do i need to find a ecu specifically for 6.1l?
Do i need to upgrade my fuel pump to factor in the extra size of engine/injectors?
are the exhaust manifolds a different pattern or just slightly larger port, if it was just l
arger my headers have quite a bit extra at start so was wonder if i could get away with just die grinding it out or if i need new headers
Or anything else you can think of that i'm missing, or reference to another board with info as this has probably been asked before. thanks for reading and ahead of time for any advice.
