I'm all over the board on what I want to do in regards to a motor in my truck.
I know for a fact that I WANT fuel injection. Doing a little bit of reading and swapping a 22RE in place of my 22R might be the easist route.

Personally an engine I do swap in needs to be rebuilt and improved on. So I figure if I rebuild the engine with a kit from EB, maybe bump the compression up a hair by milling the head down, port and polish the head and put a cam in it I should get some better then stock numbers.
Opinions?

Of course I could get all crazy and turbo charge the engine or run some nitrous through it

 

alto of $$ and slightly better than stock numbers...

With the amount of effoert for a 22R to 22RE swap (been done alot tho) Id consider a 3RZ swap... (aka later 2.7L 4 banger)

ODBII (all htose enginine monitors)
Marlin R adapter
TRD Supercharger
from what I hear - better MPG too

 

EB sells a 261 and 268 cam as well. They're really cheap, like $88 or so. I put a 268 in my rebuilt 22re and it is nice, it will actually pull modestly hard from 1600 rpm on and feels very strong and smooth at 3000. It just tops out around 4300 with that cam, doesn't really do much past that RPM.

 

Yes but ODB2 brings in a lot more wiring and other issues. I'd like to keep the wiring to a minumim if I can.

 

Personally, I would either do propane on the 22R, or swap in a 22RTE - if you're swapping the heads and everything, why not have a turbo?

OBD1/II isn't much wiring difference. That's where the 22R really shines - it doesn't have any of that crap.

 

Yea, that's the one thing I like about the 22R.

If I put a 22RE in, I'll buy a whole motor instead of just converting mine.
As for the 22RET, I'd love to but trying to find one of those motors is hard.

 

i run the EB 261 street rv head, with LCE header and intake it does OK for what it is but i like that 2.7l swap

 

I really don't want to deal with the wiring of an ODB2 system though.

Any more opinions on my idea?
How hard is it to find a 22RTE with a R151, wiring, computer, etc?

 

This is (in my opinion) your best option. Make the switch from the 22R to the 22RE. Upgrade your intake to a large cone filter (K&N FIPK or similar), then to open it up a little more, hook up with LC Engineering and get a bored out throttle body. Then you have maximized the intake and all that's left is to throw on a header (I prefer LC Engineering) and a larger diameter exhaust. These modifications will gain you significant power gains over stock components with making any serious mechanical alterations. Take this opinion with a grain of salt though, it worked for me but continue your research by all means.

Its pretty hard to find the 22R block tho R151 trubo tranny bell housing.
Ask Marlin Crawler if he has one and the price...

The variances between a 22RE and a 22RTE are not "huge".
A late model "laser block" and some aftermarket turb parts (turbo, manifold, cross over pipe) shoudl be easier to do than finding a good donar 22RTE that doent have a cracked manifold and a bum turbo...

IMHO the difference in 22R to 22RE wiring or 22R to 3RZ wiring is pretty small. if you can do one oyu can do the other.

Surf around for a 22R to 22RE conversion. I know I have seen magazien articles on the conversion - its not uncommon.

 

Have you throught of going a "hybrid" turbo route?

The 22R uses the same pistons as the 22RE/RTE. You stick with your 22R(keeps the wiring simple), use a set of turbo pistons from EB. Use a 20R head that flows much better, and bolt a turbo to it.

The 20/22R hybrid is supposed to do very well(compaired to either engine), and it's a relativley easy swap, especially seeing that you have an early model 22R(ie pre-84)

It'd be a creative solution, and if you really want EFI, mabey use a TBI system with a Megasquirt controller: with only 1 injector it wouldn't be a hugley daunting task.

 

I plan to rebuild whatever I need up using.

Bill, I like your idea. Any more info on the 20R head swap and TBI conversion?

 

There is a guy on the board with a 20/22R hybrid...kyle_22r

From what I've heard of the swap it's pretty straight forward assuming your starting with the right year stuff: an early model 22R motor and a 20R head. The 20R uses a dual row timing chain, as does the early 22R(but you could confirm that better than me).

There is a bit of info on it here

Not much, but it's something here

This is actually a swap I want to do on my old Celica once I get my truck to a stage I'm happy
with...but that could be a ways off.


As for the TBI, I know it's possible and would be simpler than a complete 22RE swap. I remember dcg9381 mentioning having done it on a supercharged 22R he built. Give him a shout and see what he's got to offer about it.

 

IIRC RTE has different pistions, and runs much lower compression than the RE. Something to keep in mind.

If you are going to spend all the time swapping a motor, why not put in the 3.4? The 2.7 is okay, but really not a ton better. 3.4 is a alot of power for that light of a truck.

As for the "intake" and "exhaust mods", i don't have any experience with throttle body stuff. However, I can tell you that I have ceramic coated tri-Y headers, a larger exhaust, and a "high flow" intake. They are USELESS. Absolutely zero power gain, and really just a bunch of money down the tubes. If you want power, boring the cylinders, cam mods, etc, are the way to go.

 

Exhaust and intake mods don't give you anything, they do work when you've got internal mods done to the engine though.

 

Thanks.
Is it possible to use the 22RE EFI stuff with the 20R head?

 

You would need some kind of custom intake. The 20R has different intake ports than the 22RE head, so you can't bolt on the 22RE intake manifold.

This would require some interesting fab work but could be cool: as far as I know the only difference is the shape of the ports and the bolt locations. If you took the 22RE intake runners and cut off the flange that bolts to the head. Then get a plate made and cut that fits the 20R head, and weld it to the 22RE intake runners. Wouldn't be that complicated to do, but would require someone that can weld aluminum.

 

Thanks Bill.

I'm talking to a buddy to get all the EFI parts I need so I think to keep it simple I will go with my orginal plan.

 

hmmm, I might have to give this 20R head with 22RE manifold a shot myself. I have buddies that can weld aluminum.

 

Yea, let me know how it works.
I might have a few thou knocked off the head as long as it won't bump the compression too high.
