22RE to 22R Conversion (EFI to Carb)
Many of our LC customers have been coming to us for an easy all in one kit for a 22RE to 22R conversion kit but that is a hard thing to do since there are so many different ways you can go when doing this conversion. So, we at LC have done the next best thing and that is to put together a list of parts needed for the conversion as well as all the options you can choose from when making the change from fuel injection to carburation. Below you will find a list we put together of just about everything you will need minus blood and sweet to get the swap done and as always if you have any questions give our techs a call at (928) 505-2501 or email us at [email protected] we are always happy to help.
Ignition Kit:
When doing the swap, you will have to remove the ECU so this will give you an ignition setup and you won’t even have to worry about an ignitor as an added bonus. On vehicles equipped with tachometers the MSD tach adapter will be required.

1082032 MSD Blaster 2 Coil, Hi-Performance
1082025 MSD Tach Adapter
22R Distributor:
With the ECU removed the distributor has to be changed next since it will no longer have anything controlling it you will have to swap to the earlier style vacuum advanced 22R distributor style. See Part#

Weber Carb & Intake Package:
The carb choice is a simple choice if you are wanting to keep the vehicle mostly stock then you’ll want to go with a 32/36 carb package but, if you are looking to make more power and upgrade the motor than the 38 is the way to go. The 38 will require upgrades like headers, camshaft, and intake to run properly; it also would benefit from cylinder head port work and 1mm oversized valves. As for what manifold to run the Single Plane style is more for daily driving and top end performance whereas the Dual Plane is more for rock crawling and bottom end power. When installing either of the intake setups you will need the install kit to match that will come with everything you need to install and run them on your motor it wouldn’t hurt to also get a set of intake studs as well just so everything installs nicely.

Fuel Pump:
Now that we have covered ignition and the carb, we move on to fueling which has a few different options for you to choose from in terms of what pump and regulator you want to use on your vehicle. All of these options will require the use of a regulator Weber’s run about 2.5-3.0 psi and most pumps put out more than which can be detrimental to your vehicle.
Option 1:
Keep the Stock 22RE Fuel Pump
If you want to keep the stock in-tank pump, you can simply install a larger regulator that will handle the high pressures that RE pump puts out. See Part# 1035042.
Option 2: Mechanical Fuel Pump
For this option you will of course have to drop the tank and remove the stock RE pump and then install the mechanical pump that is very reliable and you no longer have to worry about dropping the tank ever again to replace a fuel pump which is a plus. It will require the additional installation of fuel pump spacer and the eccentric when switching to the mechanical fuel pump from the electronic style pump. The RE models also came stock with a distributor drive gear spacer that will need to be removed for proper gear alignment on the 22R style distributor.
Option 3: Electronic External Fuel Pump
Some people prefer electronic fuel pumps but don’t want to worry about dropping the tank ever again and this is the setup for them. When going this route, you will install a Weber or any low-pressure external pump of your choice so anything 4-6 psi will do just make sure to get them as close to the tank as possible when installing the external pump.
EGR:
Encase you haven’t gotten rid of those annoying emission control devices and miles and miles of vacuum lines here is your time to do it, the Weber setup will require the EGR to be deleted just make sure to label the lines you remove so you know what to cap off and what to hook back up. If you are running a PCV you will only need one block plate for the EGR itself and if you are going for a race setup then you will need two block plates for the delete.
- With PCV (Hot Street/Daily Driver Setup), see Part# 1032002
- Without PCV (Race Only Setup), see Part# 1016038
Linkage:
If your starting off from a stock 22RE your throttle cable won't hook up to the Weber carb. Not to worry we have you covered.
