So does the arm on the splines.
That is kinda what I was going for on the spline comment
So it would be 3.14x 11mm vs 3.14x 9mm
The IDIs have a greater RPM range, tho, so it evens out and all else equal, they will make the same power.
IDI will burn 10-15% more fuel for the same power, tho, and drop pre-chambers every so often...
Mtdi all the way

Why would a 1Z/AHU/ALH not spin the same 6000 rpms that limits the Bosch VE pump?Quote from: libbydiesel on March 20, 2013, 11:58:22 pmIDI will burn 10-15% more fuel for the same power, tho, and drop pre-chambers every so often...This is enough for me to wave good-bye and never look back haha.

That is WHY IDI engines were produced. When the rabbit diesel came out, DI engines had a hard time making it past 2,000 rpms making them unsuitable for automotive use. Changes in injection technology have massively increased the DI rpm range but it is still more limited than the IDIs. The pre-chamber issue is a big deal to me as well.
