Fuel Injection Modifications

["Scott Mueller" <scott.a.mueller@xxxx>]

Can you post some pictures to the vault?
What was the cost of the components?
Can you use the stock fuel pump?
How about writing a how to article for DMCNEWS, perhaps the Moderators can
add a section in Tech for Modifications.

If you're looking for free hp, the easiest thing you can do is
replace the Bosch CIS injection with multiport efi. The CIS air flow
meter flap robs over 10% of avail hp. Std Bosch o-ring type injectors
fit the existing CIS injector ports. Use a Simple Digital Systems EM3-
D (sdsefi.com) ECU and run it right off the ign coil. ODD fire V6 is
NOT a problem. You add a map sensor, throttle position potentiometer,
air and engine temp sensors, '81 280 zx pressure regulator, and use
the existing o2 sensor for lambda closed loop. You can keep the fuel
delivery/return lines, stock ignition, idle speed motor,and the
intake track plumbing including the air filter housing which is not
the problem with performance on this engine. You can ditch the fuel
distributor, accumulator (if you want to), pressure regulator, cold
start valve, frequency valve and the lambda ECU.This is a very simple
upgrade to get you close to 150hp estimated. Programming is simple.
I've already done it.
