Hf Mpfi

[Shaguar47]

Would an HF MPFI intake manifold work for the swap from DPFI with the PM8 ecu ? Tried to search but couldn't find much info about it at all.

it will work by why would you want an hf mani its so tiny and sucky.

Yes, it will work.. but use a PM6 ECU, or get the PM8 programmed with PM6 fuel maps.

Great. Now i totally forgot it was a smaller MPFI than the si but would you still see gains in horsepower with the replacement. Especially if you run it with a PM6.

you'd basically be turning your dx into an hf and if power is what your after then this is not the way to get it. just get an si intake there are not hard to find and there cheap.

Yeah, i wouldn't bother slapping HF parts even on a B2. At least find Si parts including manifold and Pm6 ecu and dizzy (you can also use an HF one).
