907 is right. I just looked at the differences last night. U would need the new.head and intake manifold for the carberater and new exhaust manifold because the pots on the 22r head are different then the re head. I'm about to do a swap myself if I can't my my fuel problem fixed. SOOO frustrated right now.

I meant the ports are different from head to head.

Use the intake and exhaust manifolds from an 86-88 22R, and the fuel pump from the 84.
Will probably have to change out the cam shim from the jasper (RE) engine for the fuel pump eccentric from the R engine.
I think the 84 had an air pump but if not, use the PAIR stuff from a later R engine.

Not really all that difficult, and I have a stock intake, carb and maybe air filter, egr and stuff, and exhaust for an 87 22r carb here... and I think the PAIR stuff too.

Thanks everyone for the help again I think I'm on the right path now. I will stay posted.

Just wondering if anyone had an opinion on which weber carb to go with. This truck will spend about half it's time offroad ( I don't want to break the bank)but do like hills. Would appreciate any opinions thanks.

I am getting ready to do the same thing on an 89 runner. Are the distributors very year specific or will anything from say 86 to 89, with vacume advance, work???? This is the last part I need to get and I don"t want to mess up.... Thanks guys

I have a LC Enginering Pro Head, it is listed as a 22R/RE Head, meaning that you can bolt on either carb or Efi manifold

I have both 22R & RE complete engines sitting in garage, they look identical

I got a 82 with a locked up motor and bought a 22re I'm wanting to just swap everything over I got a weber with block plates all over my old 22r is there anything I will need

Ok, so I've had a bit of experience with the 22r engines, specifically the '84. I've rebuilt it several times a decade ago. I had a penchant for buying the engines with +500k miles on them, putting new guts into the engines and people would always buy them off of me, after finding I'd get 30+ mpg.

So, fast forward to now. I recently bought a California truck with NO rust on the frame. The box is beat to crap, like it was used to throw wood into, but I digress.

I'm also looking to put a carb onto the 22re engine to make it back into a 22r. Why? Well, because the 22re is a bit complicated, and I'm not able to run it even leaner than the manufacturer specs provide with the EFI. It's not going to be an offroad truck. It's going to be a freeway "putt-putt" to get me 200+ miles, once per week, to my semi and back. I'm mostly concerned with fuel economy, as my old 22r used to top out at 37-40 mpg, with the 15 inch rims, 28-34 with the 14 inch 'slicks'.

So, I'd need the new intake manifold, new 2 barrel carb, air cleaner, and... ?

Again, it's a 1986, Jasper 22re (EFI), 2.1L (?) that I want to make into a 22r.

All help would be appreciated in assembling a parts list for the machine I'd like to build! I'm far more concerned with fuel economy than power.

Yes; But now he has to hot wire an ECU to run it.

Carbed is easy, much easier to swap. Someday I will build a swap harness.

Oh; and you need a 22r distributor.

Find a 22R 85 +

that runs better to buy the complete engine with ECU.

Then you just need to worry about the fuel system to be handle the lower fuel pressure.

Merge the 22R engine harness with what you have.

Either sell or scrap the parts you don`t use.

Best of Luck!!

Thanks! As I've stated, I'm running an '86, so from the things I've heard in this forum and others, the head's should be the same.

So besides the intake, carb, air filter, I'll need a distributor and fuel pump?

Will I also need the computer? That's the point that will make the whole thing 'not worth it'.

I've got an EFI and as I've stated, I'm just trying to make it run lean as possible. Unlike most of the 22r(e) owners, I'm not trying to make it a gas-monger, mudder, offroad, beast of a machine. I could care less about horsepower or towing capacity. I just want to throw an oversized duffel bag into it twice a week and put down 100 miles each way, all freeway, to work and back, doing close to 70 mph. NOTHING ELSE. It just needs to run and idle smooth.

I've tried to tune the EFI and I keep running into emissions garbage problems, between the O2 sensor, the cold idle sensor, and all of the other things the EFI is otherwise known for using. I want it simple. Stock carb. Stock distributor. Spitfire plugs. I want it to run as lean as possible and still go down the road.

Thanks for the heads up! Any more information about my mission would be really handy? I've got both a Haines and Chiltons to help me out, but it's always handy to ask the advice from people who've been there.

I KNOW it's crazy to want to put a carb on it versus the EFI. Let's move right past that?

Now, will I have to find a matching year carb and intake for the 1986 or can I go to an earlier model like the '84, '85? I don't have the parts yet, as I have just purchased the truck this weekend.

Another point worth mentioning, nothing about this EFI is the way it should be. There are vacuum lines missing, the wrong battery in it, a bad alternator, sensors that are bypassed, the A/C pump was removed, except for the air exchanger, and it didn't even have a thermostat in it. Whomever was owning it before me was fond of cutting wires, removing hoses, and mistreating this cherry of an engine, which I know can be bulletproof for up to +500k miles, while getting better than 30 mpg.

Help? I've got a pretty good knowledge of engines, but I'm somewhere in the middle of the road as far as a gear head. Any opinions are helpful!

Like I said buy the complete running engine 22R of any year after 85 to 95 when the last ones were installed .

The older style parts are just enough different to cause fit problems.

Your also going to run into Emissions with the Carb as well if it needs to be legal in your state to run on the road.

Then California and Federal 22R engines have different ECU`s in 86 at least.

You need the Carb ECU if it needs to be legal!!

The Carb and EFI ECU are quite different.

The EFI fuel pressure is to high for the carb it needs to reduced

I can understand your reasons !!

Your best bet is to get the Factory Service Manual. Makes it much easier.

You might be able to sell your EFI parts to some one going that route.

I am putting a 22R in place of a 3VZE. The 3.slo is trashed from oil starvation, and the 22R is just getting a complete overhaul. Its simpler this way until I get all the electronics for the 22RE conversion. I should fix the 3.slo but it never ran right and I don't want to fight with it.

So the 22r head is done, just waiting on the short block. No performance upgrades, just a stock .020 over rebuild.

I'm trying to figure out what to do with the extra ports on the head. I am converting to 22r and have the parts i need but when line up the intake manifold there are 2 holes that are left open. I belive i can just block them up but not sure. Got any advice?
What to do with that open port?

Gdawghaiku

On the 22r where the intake manifold bolts on is there a port blocked off towards the rear of the head? I got the intake manifold today and went to match up but there is a port that's not covered. Any ideas?
