I was wondering if anyone could point me towards a place that had info on
Isuzu and its throttle body injection that they put on the 4ZE1.  I have a
4ZD1 that I would like to get rid of the carburetor and put the
aforementioned fuel injection system in my Trooper.  Did the intake manifold
change at all when they changed the fuel system because I was thinking that
I could just bolt the throttle body up and put a high pressure fuel pump on
the line and figure out the wiring to make it work.  If anyone could help me
I would thankful.  Also I have in mind a CJ-7 with a rebuilt engine but a
tired carburetor that doesn't work the best.  I was wondering if the intake
manifolds of the 4.0 liter high output engines of the Cherokees can bolt up
to the block of the 4.2 liter.  I know I am asking a lot here but could you
show me where I could find out this stuff.  The wiring harness in the CJ is
worn out and I figured a total swap of the wiring harness would also happen.
