After riding with a friend who has made the jump to EFI in his Jeep CJ, I decided the benefits were just too significant to ignore and decided to jump in. My car is very stock appearing, so my goal is to keep it that way as much as possible while still getting the best performance possible. I thought it would be helpful to others to document the process and share what I learn. So, here is the before picture of my engine bay:
I have been struggling with carb issues for quite a long time and am on my third Qjet currently. I have had stripped fuel inlets, warped base plates, and worn throttle shafts, and I am just tired of the car being unrelaible. I drive the car in the heat here a lot, and hot starting has been an issue forever and despite all sorts of attempts, the problem persists. I know many will question my choice to do this, but I suggest you drive one of these EFI systems before you judge. The starting is so easy, the throttle response is amazing, and with an in-tank fuel pump, there is no detectable pump noise.
I currently run the stock distributor with a Pertronix igniter II electronic ignition, and I plan to retain that and not have the EFI system manage spark.
And here is what I bought:
I bought the Edelbrock Performer EPS manifold to avoid using a carb converter plate which would have made my stock air cleaner hard to reuse and I wanted to have a discreet location for the coolant temp sensor. My stock temp gauge sensor is in the head and the EFI kit does not recommend using that location for their sensor. Using that location would also require me to lose my stock temp gauge. My plan is to powder coat it chevy orange and to reuse the stock oil fill tube and thermostat housing. The large air cleaner will cover the Edelbrock logo but I will need to change to a 90 degree heater hose fitting which will not appear stock.
I decided on the Edelbrock E-street EFI after tons of research and the recommendation of two friends who have the system. I also liked the option of running a returnless fuel system which eliminates the need for a fuel regulator under the hood.
I also purchased the Spectra Premium EFI fuel tank from Rock auto:
It appears to be a very quality tank and the recent reviews of the redesigned baffle system are very positive. The price is just too hard to pass up and it will appear totally stock.
I purchased everything except the tank from Amazon and the pricing was much better than the normal speed shop vendors (Jegs, Summit, etc.) All in, including fuel line, fuel filter, fittings, gaskets, stud kit, fuel pump block off plate, and O2 bung clamp is just about $2,500. A lot of money, but not nearly what this would have cost a few years ago.
Most everything arrived, and I have started disassembly. I am currently sandblasting and coating a bunch of brackets and such and started the powder coating of the manifold. With the long weekend, I hope to make a bunch of progress and will update this thread as I go. Wish me luck!
