anyone else know if this will work ?? will a 22r block mate up to a 22re head to make a good 22re engine??

From my knowledge(limited) the 22R head flows better on the 22RE block,They aren't a direct bolt on though,The 22R head needs to be "milled" to fit,what that intails? I don't know.I believe the 22RE blocks were better.
I've read about it before,but the best thing to do would be google or yahoo search for info.

ok that helps a little more, got water in the oil ... hopin the previous owner just put the head gasket upside down... but fearing the block is toast

The 22re blocks and the 22r heads were the best of the series. I have heard of some mixed set ups working with out further mods and some not. I'm not really sure why they would/wouldn't. I was going to try it myself pretty soon but until then I cant help much more. Good luck

AFAIK, the 85-95 22r\22re blocks and heads were the same. the early 22r 84 and before were a different block and head.

i just picked up a used 94 22re long block, approx 65k miles for $100 from a wrecked truck. im going to put a 22r intake on it and swap my cam\rocker assembly, carb and header onto it and toss it into my '79 next month.

May want to pull the thermostat housing and be sure that the timing chain has not worn through.

ok, yea the 22re block is in my 86 4runner, witch i hope isnt toast. but the prev. guy put a new timing set ,head, fuel filter, & water pump/timing cover ,but wasn't very good with a wrench . so i'm hoping that he put the gasket upside down. if so ,i hope it's still good. but if not my 83 pick up may donate a short block. if it works, but i think that engine is from an 85 vintage truck , soooooo i may have to check some numbers on the block . let me know if your swaps work out or not, & i'll keep you posted if my swap works uot or not...

I figured the blocks were the same but whats the deal with the 22r head flowing better than the 22re? If the heads are the same how is that possible? I doubt that Toyota would go through the trouble to change that one thing if they are using the same design.

I'm pretty sure that there is a couple hundred threads about this one on here, but in all fairness, I think that the block would be the same, but the heads would be different on the 22r, and 22re. I know you can bolt the 20r head on the 22r block, and you get some extra horsepower, and torque, because it has a little higher compression(I believe that is the cause) and it probably flows a little better, too. Hope this helps.

afaik, the big diff. is the efi vs. carbed. heads being the big diff...

WSUWESTON

I believe that they are differant. One of them is taller than the other. Just can't remember which years.

GLT-4-6

I believe the difference would be that the 22r head doesn't have injector ports. All other minor things aside, the 22re is direct injection and the 22r is carb., If you use a carbed head where will you put the injectors? lol.

I'm pretty sure we have lost the original question here. Anyway, we know that the blocks are the same and the heads are different in the way that they take in fuel and air. If you need a block either way will work. If you need a head you have to use the one made for your vehicle.

Here is the fun part. I have plans on putting a turbo on my 87 truck and I would like to swap it from carb to injected. It doesn't seem like it would be very hard after getting everything needed to make it work. I'm close to having everything that I can think of already, I'm just waiting for my 22re head to come back from being cleaned up and rebuilt. Any input would be great.

navyredneck

The head and blocks are exactly the same.

How do I know this? I ordered an engine from Oregon Engines and they send you the same block, head, crankshaft, camshaft, lifters, valves, gasket set. The only difference is that you need to install a lobe on the camshaft to ensure you have a means to drive your fuel pump in the case of the 22r.

Now don't ask me how I know the last part...

what years 22r and 22re are we talking about here?

All 85+ 22R and 22RE heads, blocks, and guts are 100% exactly the same. The ONLY difference, is the cam eccentric bolted to the end of the cam shaft to drive the fuel pump on carburated trucks. On EFI (22re) there is just a simple spacer.

84-earlier are NOT the same as 85+ parts.

You CAN build a hybrid engine from a 20R/22R combo.

However, if you use an earlier 22R (84 earlier) or 20R head, you will need a new exhaust manifold, or will need to drill out a hole for the center stud (not recommended)

More incorrect information.

Since the head is the same between all 85+ 22R and 22RE's, they ingest fuel in the exact same manner. The EFI engine is NOT direct injection, since the injectors plug into the intake manifold, and not the cylinder head itself.

Just remember to take "AFAIK" and "IMHO" and "I Think" replys with a grain of salt, Toyotaman11, because often they are guessing, or plain have no idea what they are spouting.

BTW, you may ask how I know? I have worked for Toyota for 6 years, so I think I know a thing or two about them

GLT-4-6

My bad on the direct injection. I'm not sure what I was thinking about. Out of all the things I've read about the 22 series I have never seen anything saying that the heads are the exact same. I never thought to try it from everyone saying it wont work so I only know what I've been told.
