Thanks for the reply, it's nice to hear from someone who actually has
one. This sounds like their more expensive closed loop system. Do you
have the cat. converter?
My 1776cc is a type 1, I forget whether a 71 bus is Type 1 engine or
Type 4. If type 1, did you have to modify the heads for a temp sensor?
Any other engine mods or was it basically bolt on plus wiring and
running fuel lines?
The new supply line is 1/2", is that ID or OD? Is the return line also
1/2"?
I'm not that familiar with busses, is that mileage less, about the
same, or more than stock?
Were the 48mm the only ones offered when you got it or did you chose
them over the 40mm? Do the 48's seem about right for the engine or are
they overkill for that size?
Thanks,
Jeff

I have had on of CB Performances DFI systems installed on my engine (1835) for
about a year now. It is based on GM's DFI system. The ECU comes from an Izusu
(mounted under the rear seat on the drivers side) and most of the other parts
(oxygen sensor, MAP sensor, etc.) are of GM origin. Installed it looks like
dual Dellorto's. Cross throttle linkage, Dellorto manifolds with 2 Lucas
injectors in each and 48mm throttle bodies topped off with Dellorto air
cleaners. The O2 sensor is mounted in the exhaust header's collector. The
larger gas line (1/2") comes with the kit. I removed the gas tank cover and
pulled filler neck to tap and insert the return line. Both the return line and
fuel line pass through the firewall with PVC fittings used as bushings.
It was, at the time, not an installation for an inexperienced or
faint-of-heart mechanic. CB Performance was _very_ supportive at helping me
getting it set up properly. This included an ECU exchange and many phone
calls. Mine was the first bus installation they had done. The wiring harness
is built to order.
It runs super strong. Mileage is about 17-18 around town 20-22 on the highway.
And the best news is that, here in Nevada, smog checks are now a piece of
cake. All in all I am very pleased with the set up.
