FoxyRoadster Posted July 5, 2011 Report Share Posted July 5, 2011 Is the 78 Z's bosch EFI worth keeping or would it be better for me to goto carbs and run an external ingiton system? Opinions and suggestions please! Quote Link to comment
ggzilla Posted July 5, 2011 Report Share Posted July 5, 2011 Keep the EFI, it is smoother and makes more power than the previous twin carb systm. You can use the stock distributor with carbs, or can use an external crank trigger ignition with the EFI. They are independent. Quote Link to comment
DanielC Posted July 5, 2011 Report Share Posted July 5, 2011 Years ago, I put a JDM L-18 engine into my 521. The engine came with EFI. Do I wish I would of kept the FI stuff? HELL YEA! Quote Link to comment
ggzilla Posted July 5, 2011 Report Share Posted July 5, 2011 Yes, the L18E SSS engine was the first one to use EFI, even before the Z-cars. Quote Link to comment
Z-train Posted July 5, 2011 Report Share Posted July 5, 2011 By 78 all the bugs were worked out of the Bosch system. Quote Link to comment
ggzilla Posted July 6, 2011 Report Share Posted July 6, 2011 Even by 1975. Bosch Jetronic EFI was used in european cars since 1967. Then Nissan made their own version which had new bugs that the Bosch version did not have... Chrysler had EFI in 1957 but it was very unreliable and they stopped selling it until later.

ppeters914 Posted July 7, 2011 Report Share Posted July 7, 2011 Even by 1975. Bosch Jetronic EFI was used in European cars since 1967. FWIW, there are different Bosch Jetronic EFI's. If you're interested and/or bored: http://en.wikipedia.org/wiki/Jetronic Quote Link to comment

You're thinking of GM. Quote Link to comment
PurePontiacKid Posted July 7, 2011 Report Share Posted July 7, 2011 go with carbs, especially if you have an S30. Stock EFI sucks balls. Quote Link to comment
ggzilla Posted July 7, 2011 Report Share Posted July 7, 2011 GM had non-EFI FI in 1957. The famous fuelie corvettes... Chrysler had electronic FI in 1957, made out of discrete components. They had some problems with it... it was Bendix FI made for the 1958 model year, and later sold to Bosch which created Jetronic for 1967 and then improved it to L-Jetronic with integrated circuits for 1974 ... and now we come full circle.
