80 series injector pump
Posted: Thu Mar 31, 2011 12:30 pm
Wanting info on if a 1hdt injector pump will bolt straight onto a 1hz engine? I've been told that the 1hdt pump is bigger inside and flows more fuel. Any help would be great thanks
yes they will bolt up, BUT they have different cam profiles and different injection timing,so it may not be a straight up swap.
I fitted a 1HZ pump to a 1HD-T and never got it to run well enough to use it. Not really sure why??
