EFI Frequently asked Questions: 

1) Why have we designed a kit to change from Carburetors to Electronic Fuel Injection?

We’d like to keep these cars on the road and with today’s poor fuel quality, increasing difficulty in finding parts, and increasingly costly repairs, it was important to us to find a solution. 

 

2) Do you make one for my car?

Currently we are only working on a kit for 1955-1965 356’s but will definitely explore other applications (912, 914, 912E) in the future. Side note: If your 356 has a 912 engine, this kit WILL fit just fine. 

 

3) Does my car have to be converted to 12v for it to work?

Yes it does. You will need a minimum of a 35 amp charging system, with our 12v alternator conversion being the recommended method.

 

4) Why should I install this kit on my car? What are the benefits?

This kit has many benefits such as, easier starting, better drivability, altitude compensation, more precise control over fuel and timing. 

 

5) How much time does this kit take to install and how difficult is it to install?

This kit was developed for someone moderately experienced working on 356’s. You can expect anywhere between 6-10 hours (possibly more, depending on skill level), not including removing and reinstalling the engine.

 

6) What’s included in the kit?

This Kit Includes: 

  • ECU
  • Completed Pre-Terminated Wiring Harness
  • Throttle Bodies 
  • Fuel Injectors
  • Intake Manifolds
  • Sensors (Air Temp., Cyl. Temp., Throttle Position, Wideband O2 Sensor)
  • Fuel Lines
  • Fuel Filter
  • Fuel Pump and Pressure Regulator
  • Spark Plugs and Wires
  • Distributor
  • Ignition Coil and Module
  • All Associated Hardware Components 

 

7) Is Tuning required?

The kit will ship with a base map that should get you started, however, due to many variations in engines the vehicle will have to be tuned . Ideally having it professionally tuned on a dyno would be the best route. With that said, you can do it yourself via a laptop (windows or Mac) or an android device (information provided in kit instructions).

 

8) How much permanent modification must be done to my vehicle when installing the kit?

A few small screw holes for mounting the ECU and Fuel pump. An O2 sensor bung is included in the kit and is strongly suggested to be installed in the muffler to aid both tuning and allow full functionality of the kit.

 

9) How much does this kit increase horsepower?

This kit was designed for increased drivability and improved starting first and foremost, but from what we’ve seen there may be a significant increase in power over your old carburetors. It does vary car to car. With a proper tune, it will perform at least as well as your carburetors did. Our goal was to make these cars easier to drive in an effort to keep them on the road.

 

10)  How much is the kit?

Current projected price, depending on options, is somewhere between $3000-$3500. Keep in mind, this is comparable to repairing carburetors, a fuel pump, and a distributor. 

 

11) How do I get one? When can I order one?

The kits are not currently for sale. We are finalizing a few details. Please stay tuned, as soon as they are ready we will post them on our website at Allzim.com.
