Ok so I got a 91 4x4 p/u So it finally laid down on me got a rod knocking bad so I have a 82 model engine with the dual roller timing Chain So my ? Is can I fuel inject this 22r in this 91 truck or should I build the 22re does one produce more power than the other. And last question would I need to use the efi cam in the 82 22r. Thanks guys any advice on this is great advice.

I don't remember the cutoff year but the ports are different and I don't think you can EFI that year 22R.

I've seen write ups on the how to swap 22r into a 22re. But it is a challenging task. Different blocks/heads so no knock sensor boss. The most power would be a 20r/22re hybrid but difficult or highly skilled and expensive build.

Probably easiest and cheapest to go with the same motor generation.

Oh some places have laws that prohibiting older motors going into a vehicle.

You've an interesting situation there.

An 82 22r, which could have different head / port configurations than the 83-85 22re used in the Celica and Pickup / Hilux.

You could possibly use the celica / 22re head on the 22r block, with the 91 intake manifold but I won't guarantee it due to differing vacuum and coolant routing, and the exhaust manifolds are different between all those meaning the carb'd 22r is different from the EFI 22re which is different from 85 compared to 91 so the PAIR system on the 91 will likely not work with the earlier head and required manifold.

And I rambled, so?

Long story short- you would probably spend more (time and money) trying to make the 82 22r work in the 91 than you would spend fixing the rod knock in the 91.

The 91 intake manifold won't work on it either. Your talking square versus round intake ports. Pretty sure the Celica's were the same way.

Ok so I went out and checked it does have a knock sensor bung on the 22r block. So actually it came out of a carbed 87 truck but I know it wasn't stock in that truck seeing how it has a double roller chain and domes

So no one here has actually attempted this ???

camotow

I'm assuming it's an 82 model from the research I've done 82 was last year with double roller timing chain. Is that correct. I owned several 22r and 22re trucks but this is the first time I have tore into one and found domes and a double roller timing chain. So this engine was in and running in a 87 carbed truck as I said I never drove it but did hear it run in that truck So idk I was just thinking that maybe the longer stroke would make a lil more torque.

Stroker 22re is made by the grind on the crack shaft.

I have't done the swap but was dreaming of the 20r/22re hybrid. But really for the amount of money and time that would yield a small power return when compared to an engine swap, better off swapping motors 5m/7m. A painful reality of the 22re is you can modify the motor all you want and still have a small 4cyl. The more upgrades you do the more you effect reliability, to an point even some bolt on modifications.

There are write ups on this swap and most others. Just got to search.

camotow

Ok so I'm hearing I can use the 22re head on the 82 22 r bottom end with modifications. Is it worth it ?????

xxxtreme22r

NO. Not going to work. A 22re head in a very early celica is the same head that's going to be on that 22r you have in the truck now. Your standard 22re head from a pickup/4runner is NOT going to work.

The details on what's needed and what works as far as hybrid motors is all over the place on here.

Only 1 guy has attempted the late head on early block and to my surprise (yeah right) has not come back to update us on his progress. Big surprise. My guess probably didn't work. Probably because he couldn't get the right timing chain length. And your going to need a good machine shop that really knows what they are doing to make that work. And it's just not cost effective to do so.

Why not just put the 22r in the truck?

Its not that hard or expensive. Bolts up, need a fuel regulator to drop pressure to 5psi, and a linkage. I am certainly planning to do just that since I have a '88 less a brain, so a brainless engine goes in.

xxxtreme22r

Dropping the EFI fuel pump pressure down to 5 psi is a bad idea. Even if you use a return style regulator.

camotow

I went and looked I have both engines on stands the 22r and the re they both have square intake ports ??

camotow

Ok so I went and pulled intakes and bolted the efi intake straight to the 22r head with no problems at all. Every bolt hole lined up perfect. How is this possible

xxxtreme22r

Wait...... damn, round intake holes are the 20R intake/head not the early 22r. All this talk about hybrid engine confused me. lol. Exhaust manifold I know for a fact won't work though. Bolt pattern is wrong. Also round exhaust ports versus pear shaped.

Done on drag cars all the time. Fuel pump is gravity fed from the tank and pushed to the regulator on the engine, or next to it.

Unless you know something I don't in which case; do please tell?

xxxtreme22r

So drag cars are running 50-75 psi fuel pumps down to 5psi? I don't think so. GPH will suffer greatly if using a return style regulator and the pump will be way overworked if you use a dead head regulator. This is why they make low pressure high flow pumps.

Return regulators are used if your GPH requirement is on the lower side. Kind of like if I tried to use Holley Red fuel pump. Puts out 7psi but 97 GPH is way too high for our little 22r's. So I would use a return style regulator so I am not overworking the pump.

If your running a carb'd drag car you's run 1 or more Holley Reds (7psi 97 GPH) or Blues (14 psi 110 GPH) or blacks (14 psi 140 GPH) in parallel. Depending on what you need GPH wise. This is one reason why dual feed adapters for carbs were made.

Or Mallory (Mallory 5250) has a nice lower pressure 250 GPH 6psi pump as well.

But a 140 GPH pump will support up to a 840 HP engine. While that 250 GPH will support up to a 1500 HP engine.

If your running an EFI drag engine then you'd go with the one of the Holley in tank 12-9xx series pumps. Or a Walbro unit, or so other high pressure offering.

That's where the time and money come it. Or skill and access to needed machinary. Most headers for a 22R/re designed for the early years have both bolt patterns on the flange. So can be bolted to a 20r head.

The intake ports have to be tig welded up then machined down to spec for the 22re intake.

You have to use the older block, without saturn stamp. So no knock sensor boss. This can be added or retapping an existing boss. BUT you have to make some crazy adjustments to dial it in.

So it is possible but if you do not have the skill and access to machinary it is cheaper to go other routes.

DOA sells a complete drop in hybrid but is spending and DOA seems to be hit or miss on quality from the pot I'm read.

LCengineering has a drop in stroker but spendy too. You can buy a kit from another company but I forgot their name.

Thanks mudpigg for the info. But I have kinda hit a confusing conclusion Ok so I have the 22re outta my 91 and the 22r with the domes and double roller timing chain !! Both heads have square intake ports and efi intake bolts to the 22r head and every bolt hole lines up Perfectly and I have both engines side by side and both have knock sensor bosses I had read that only the 81-82 22r had the double timing chain with the long stroke block. The 22r came outta 1987 yota p/u that was carbed I pulled it out with a bad head gasket and for the manifold the 22re does have pear shaped ports and the 22r does have the round ports This engine has been built sometime or another the rockers where still gold and clean and can see where they wrote the valve adjustments on the rockers still. No ring groove at all and the timing chain guides are barely even rubbed by chain So I'm confused now as to what I have here. Is there any numbers or markings on the head and block that tell the year models. I have worked on several of the 22re engines but this is the first one I ever seen that had domes and a double roller chain in it. Thanks alot guys I can post pics if that would help !!!

You may be set, look on the side of the block if it has the saturn shape raised casting mark you may be in business. Though I think there is a difference in cam shafts so good time to upgrade. I'd recommend a stock head gasket instead of an aftermarket. The dual timing chain is stronger than the single.
