I want to do the conversion from a carb to fuel injected, but would like a little help. If there is a thread that covers all of this then a link would be great, otherwise let's make a good thread about it. I'm looking for a list of parts and a little how to on doing this conversion. I have an 85 22r right now. What do I need to do and what do I need to get it to a 22re?

Pirate 4x4 has a lot of info on this if you just do a search. I'll be starting the same thing on a 1984 truck shortly after my next smog check

Here's what I have:

-upper & lower EFI intake
-injectors (+ cold start injector = 5 total)
-computer
-harness out of entire donor truck basically
(note: computer, injectors and harness should come from same vehicle. Changes were made throughout the years.)
-stock vacuum devices
-EFI evap system
-stock air intake w/ airbox
-knock sensor (if donor EFI is from 85 - later. 82-84 EFI Celica computers do not use a knock sensor)
-electric fuel pump
-pressurized fuel lines
-EFI fuel filter
-EFI distributor
-(probably) EFI coil
-all required o2 sensors (the quantity and location of these differs between years. so pay attention and get a book!)
-Start injector time switch

There's still more thermal vacuum switches and stuff, plus a LOT of relays. THats why, if you're gonna buy parts, try and take it ALL from the same truck/RWD Celica.

The great thing is that both of our trucks (84 & 85) were pre-equipped for EFI and thus it should literally be "plug and play".

mmm im drooling. im fixin to do an efi swap soon too just waiting on a good priced parts truck

and btw not all 84's are efi capable. (the early model 22r doesnt have proper thread holes)

XtraSlow_XtraCab

lol Ya know, I've been told that. Frankly I'm not worried about it. Granted I haven't looked for myself on my motor yet, but there were Celicas out with EFI since like 82 or 83. If those have the right holes, why wouldn't a pickup? That'd be stupid of Toyota to ignore that opportunity of interchange.

algranger

the best way to tell is on the exhaust side of the block near the bottom in the middle there will be a little cap with 2 bolts. this is for the turbo which means its a late model efi capable.
and i donno why they would do that but i know my DD 84 has the early model

algranger

ok nevermind on the bolted cap but there is a little thing poking out there in that shape... i was close

XtraSlow_XtraCab

Turbo didn't come out til 86. Unless you're saying its a "definite" sign in which I'd have to agree.

From what I understand... if you have the "wrong" motor for EFI, its missing the mounting bosses and threaded bores for 2 or 3 of the intake bolts. In which case, worst case scenario, you need to go find a different head. (Or get creative). I'm positive the 1985 motor will work... I guess its a coin toss as to whether or not I'll have this problem

algranger

the new head wont work on the old 22r the length of the block changed. you could probly run the thing short of a few intake bolts if you were ballsy but i wouldnt do it. 85 will definitely work i have and 85 motor in one of my trucks. i was confused about the turbo thing... i think. well whatever screw it the point is theres a thing there
btw i like your sig, aint it so true!

XtraSlow_XtraCab

haha Thanks! Yeah she's a slow old gal (230k miles!) but you won't hear me bitchin' the next time it floods! I dream of MY version of "Dante's Peak" and get all excited in the pants.

algranger

Haha! Yeah me too it floods here a lot but i just moved here so ive yet to see. mines slow and tired too runnin 120 on all 4 not too bad not too good either but i love her. wouldnt sell her for the world
I've been known to pop a fatty while wheelin

If I was contemplating this conversion, I would phone LC Engineering and ask them what parts I would need from then to make the conversion. You don't have to get the parts from them but at least you would know what it would take. Tim at DOA Racing builds hybrid motors with 22R bottom ends and 22RE top ends. He could also be a good source of information.

At least if you knew what it took with new parts you could then start looking for used substitutes.

Another thing to consider if you go to a Celica GTS for the 22re- the injection system used on these prior to 85 was an analog system whereas on the trucks it was a digital system and many of the components are not interchangeable.
As well, if you're in California at least, your best option to be emissions-legal is to swap components from the same or newer vehicle.

Thanks for all of the info. This should be a good start. Now here's the next question, I know they came out w/a turbo model, is there any difference in the blocks? Has ony done the converion from a 22r to a 22ret (I think that's right), if so is it worth it. Thoughts/suggestions?

abecedarian

the 22rte and 85+ 22r/re blocks are all the same except for (note the red circle):

is drilled to facilitate the turbo oil return. As far as I know the heads are the same as well. Pistons are forged in the turbo and lower compression.
As for if the swap's worth it... depends on what you're looking to accomplish, but it isn't a 'cheap' modification for the modest gains.

Here's a quick question. I have an 85 extracab w/110,000 original miles w/22r engine in it. The truck is in pretty good condition for how old it is. Especially the undercarriage and all the parts underneath.

I just sold an 85 extra-cab today that was beat to hell.


I have fount another 85 extra-cab SR5 EFI w/212,000
They say it has no leaks
Body is straight w/little rust (no dents)
Comes w/canopy
Power windows
Good heater
Passed emissions until next sept.
Said ,"the interior isn't bad, but afterall it is 23-24 yrs old"


There are three options here:
I buy the Red truck and keep it (SR5) and sell the Blue one (original 110k miles)

I buy the red truck, take everything out of it and put it in the blue one (SR5 items and the EFI system) and put the replaced parts of the blue truck in the red one including the carb system and then sell off the RED truck

I don't buy it and keep the truck I have now (blue) and convert it to EFI hopefully this summer.


Someone please help me w/this decision. It's tough

How much is the red truck?

894x4pickup

Im going to attempt to swap a 22RE from a rolled 86 pickup into my 84 pickup. Im planning to take from the 86 as much as i can. My Question is, Is there anything, besides human error, that can get in the way of swaping the 22RE into the place of the 22R? Also can a ignition system from the 22R be used for the 22RE?

abecedarian

Yeah... how much for the EFI truck?
Personally, I wouldn't cannibalize a working truck just to swap EFI in. I might swap the longblocks, so the lower mileage block is in the EFI truck, then sell the carbureted truck.
You could probably find a wrecked truck that you can salvage the EFI components out of for less than a grand.

abecedarian

If you're swapping in the 22re and keeping it EFI, you need everything connected to the engine including the ignition and ECU, ballast resistor for the fuel injectors... fuel tank and pump... everything. Well, you don't need the alternator, a/c compressor or power steering pump unless you really want to.

1987 2wd sr5 turbo manual trans pick up with 330 k. turbo doesnt function and head is probably cracked. Whats it worth? Love this truck but have to let go..
