Im not asking if a 20r or 22re can go in my car or anything like how hard is the swap? my question is what is the difference between the two motors? i know they both can be carb or EFI but i was wonderin if the two motors can be combined. i was thinkin maybe the 20r head can be bolted up to the 22re block and run EFI. i dont have both motors right now to see for myself so i was wonderin if anyone had some info.
i know it isnt directly related to corolla but it is the motor i intend to put into my 1983 SR5 corolla. its a more torquey and bigger bore motor.....i know it cant rev as high and will more than likely be carbed but i just want to know if you know of any specifics on whether the head and blocks mate up. let me know please.
its not really the fuel delivery i am woried about i need to know if the head of the 20r head will mate on the 22re block. the 22re is basically an over bored 20r with fuel injection but yet the 22 also came carbed. i dont know for sure if both blocks have the same water and oil passages or the same bolt patterns......thats the main thing i need to know. but all help is welcomed. thanks to both of you though. im new to the corolla but im not new to toyota i own an MA70 supra and a AE72 corolla.
I'll rephrase.. the Corolla guys won't have as much info for these motors as the truck or Celica guys would, since Corollas never came with this motor.

Short answer: yes IIRC it ups the compresssion also, I've heard rumors of 250hp N/A motors running this combo and still have a nice flat power/torque curve. This is one of Toyotas best engines, it's a shame more people dont stuff them in these tiny cars.

Have you begun the swap yet? I'm considering the same, but with an 87.

Negative. I have since had my MA70 stolen and had to buy a replacement car with all my build money because NC cops couldnt find my car nor did I get any money due to only having liability. I bought an SC400 though and when I get back from the desert I will be mating a W58 to the 1UZFE I recently moved off base as well and staying in a pretty cheap house so I will be trying to save enough to do this build later on.

That really sucks, i have a Ma70 still waiting for Md State Troopers' do anything about that, hatch window busted out, bullet holes through front windshield, and slashed tires, etc.
If you need any info on 20r's / 22r's thier basically all the same except the intake ports are round on the 20r's and squarish on 22r's 20r/22r hybrids are possible but there was two different timing chains double and single, i think mating to a 22re would be more so waste of time, i believe thier deck height is different, making the install of timing chain a pain. I'm running a '81 22r shortblock w/ '79 20r head, it really wasn't all that hard to do. I just had to use 22r headgasket... I have header, weber 38 carb lce underdrive pulleys, electric fan, 2.5" exhaust, egr block off's stage 2 pnp head w/ good street cam, just got her together this weekend, runs alot better then stock config...(20r/22r's exhaust ports are the same) I'm not the most knowledgable on the R series motors theres alot of guys in hulix forums that are masters on them. need anymore info let me know
Thanks man, I intend to do pretty much the setup you have into my AE72 coupe, that or the thought of a KA24DE has crossed my mind a time or two. I drove an AE86 with a stock SR20DE and it was really responsive and still had the balance the AE is known for. But it really depends on my funds at the time and what is available.
my 20r/22r hybrid didn't cost too much to do, if you can do most the install work yourself its alot cheaper. all my buddies toyota trucks and my buddies nissan hard body both with header, upgrade in throttle body or carb and exhaust, both are sticks, and neither one of the trucks can hang with my yoda and i'm still 3 spd auto tranny, the swap is decently responsive on a stock level theres really no advantage, with bolt-ons pretty sweet. any of the swaps would be nice it really all depends on the money i put about 2300.00 into my set-up...i'd assume i'd have 130-140 horses at the rear....

I HEARD (so dont take my word) that a 22RE block, with early 22R (82-84) pistons, Converted to a special double row chain, and a 20R head makes a runner. 10.4 or 10.5 to 1 compression ratio. Probably 10-15hp more than the usual hybrid.
79Yoter, 140 at the wheels? Our combos are similar, and its like 140 crank. Dont be embarrased though, it killed, KILLED my buddies cammed stripped out B16 vtec EG hatchback. Its the torque that matters...(I was across the intersection before he got up on the engine)
Dont expect high HP numbers out of 20/22r/Hybrid combos. They are torque motors. My hybrid can brake stand sticky 245 BFG's into smokey oblivion at 2500 rpm.

Yea I really just guessin but i'd have to say it pretty awesome, i have after market pistons in not that it really made that much of difference but i do love the set, she pulls pretty deceint for the motor. i bought my pistons from lc engineering, was going to go with toyota performance, just didn't like thier cusotmer service. anyway i want to get more for the truck just don't know what to do next but the torque output is pretty good.
Not really wanting HP anyway, torque is what powers a car through drifts, the only thing i would possibly want is maybe higher rpms so i can hold gears longer. But this has been put on the back burner meaning i still want to do it but im not to pressed to get the parts in and start working on it.
im looking on putting an 84 celica 22re into my 78 corolla, never done anything like this before and was told to check the mounts and everything to see if they will work so asking for any help to see that the swap will go smoothly, please let me know if you got any answers
