84 Toyota PU 4X4 stretch cab 5spd lifted 4" 33s on Alcoa 10" rims I knocked a rod out of my 22r motor and will be rebuilding. Does anyone know about souping up this engine. I have heard comments about leaving it stock is better but being an old hot rodder it seems to that a cam and header and better induction etc would up overall performance. I have 33 inch tires and stock gearing and I"m not happy with highway performance at all. Any comments or advice?

 

The general consensus on here is no matter how much money you stick into the 22R (or 22RE), it's still going to be slow.

you can soup up a 22RE to be really fast, but it would be MUCH cheaper to buy a different engine. would take too much money to do it. so in other words: you can, but its not worth it.

 

REALLY?! get new gears!

 

Some say to buy the midrange cam from Enginebuilder and put on headers along with a K&N on the intake and 2 1/2 exhaust with high flow CAT. I strongly recommend, if its a FI engine, to have the injectors cleaned and tested. Dr. Injector in Washington State is one. Watch out for any head cutting by a machine shop. Other than a skim pass to clean it up, further cutting will retard the cam timing and you will need a shimgasket for the head or an adjustable cam gear.

That is about all you can do on a low budget

There are currently some OEM Toyota turbo parts on Ebay. You can build the 22 with turbo pistons and a turbo head, balance it and install Supra injectors and MAF. My mostly stock 87 turbo, which ran like a scalded ape after turning up the boost, intercooler install and adding a CT26 turbo, had a computer especially made for the turbo with a different part number. Will you need that , I don't know. There are some 22r turbo web sites you can hunt down and read about.

That is about all you can do on a moderate budget. Beyond this, go see your Banker.

Re-gear, you gained as much as 4 or 5" in tire over stock height. I run 4:88's with 33 inch tires and it's almost the exact same gearing as stock with stock tires. Then worry about power adders. I have a Weber 32/36 carb, Engnbldr 261C cam and a 2" exhaust with a flowmaster. Guess what! It's still slow.

 

I think I have the best valve specs for this motor put away somewhere..I'll look for them. Is it a 22r or 22re. re is fuel injected..thats the only difference.

 

here are some cam specs for a couple of different range cams. http://www.4crawler.com/4x4/CheapTri...shtml#Camshaft

 

Anyone who says you can't get power out of a 22R is a dumbass. Plain and simple. If you want a 22R with balls, do a twin turbo set up, if that doesn't do it for you, put a supercharger ontop of that too, not enough? Exhaust, BIG Cam, Port Polish, Bored & Stroked, Big Ass Carb, or EFI setup.... Basically how fast you wanna go is equal to how much cash you got. Theres enough of these damn threads to fill a graveyard, if you want fast, I don't know what the hell you are doing driving a 4x4 toyota... Granted with all that boost, carburation, and cam, you'll have a horrible time trying to crawl the malls, or go wheelin'

P.S.-Please use the search next time...

 

You can do that. Or you can spend a fraction of that cost and swap a V6 or V8 into it.

 

I'm not really worried about "fast" so much as I'd like to be able to do the speed limit in OD. I'ts a 5 speed. I"m pretty happy with off road performance. One of my friends had 5.29s with an automatic and the only difference seemed to be the RPMs at speed. I've thought about a 4.3 or 350 but for now I think I'm gonna keep the 22r. I'ts a carb motor (I sold an EFI motor about 3 weeks before I knocked the bearing out of this one, figures). I have another 22r I can stick in it to keep me going while I work on my keeper so I can take my time building this one. I'd love the turbo set up but at this time I think my budget will limit me to head work, pistons, cam, header, carb etc. Any ideas are much appreciated. Thanks for you guys input. Beer is good

 

I was wondering about the same thing. But it is mostly Hills that get me, I just like to get up them and not slow down too much. How about just running some Nitrious for quick boost up a hill?

 

You need to regear if you want to run 5th. I was running 3.90's and 33" tires and I had to be doing about 70 to shift into 5th gear, and it was lugging. Your 4.10's won't be as bad, but re-gearing is the way to go.

 

What gears would a stock 84 Runner 4x4 w/ 22r have?

 

The mechanical advantages of re gearing can not be overcome by adding power. At least not by the amount of power that can be achieved by rebuilds and bolt ons, with the exception being maybe a turbo as long as tire size is not too drastic. I installed a turbo and saw noticeable improvements due to 25 to 30 more hp, maybe even more, just a rough guess since I have never had it dynoed. But that being said it would have been much cheaper to just regear. Trust me. I made this mistake when I first started out. I was unhappy with the highway performance so I figured I needed more power. Rebuilt with cam, head with larger valves and and northwest offroad header. Still didn't do that great. I should have just regeared. But since I will eventually be running 35s I am going to wait and just leave the gears stock with 31's.

 

Sorry to bring up an old thread, just don't a search on if someone has ever done a twin turbo swap on a 22RE, and I came across this thread.

I am currently working on a CT12 twin turbo manifold.....just for kicks. I should have it ready to bolt on within a couple weeks, just need to find a donor engine to test it on now.

Anyway, one post caught my eye and that is what TrusyRusty said. I will have to somewhat dissagree. You cannot get a lot of power out of the 22RE very easily, you know why? Airflow. 22RE heads don't flow worth crap. That is my only concern with spooling up these two turbos. Sure the turbos were ment for a 2.5L I6 and the 22RE is a 2.5L I4, so in theory you would think the 22RE would do just fine.....WRONG!!!!! The 1JZ head flows around 200cfm on the intake. A 22RE is a whole wopping 130cfm. This is SEVERLY going to limit what the 22RE engine can really do.

You can get 22R head to flow juast as much, and more, but you will sacrifice low lift flow, so off boost power will be terrible.

So, anyody know of anyone that has done a twin turbo 22RE?

 

Ask Tim at DOA Racing. I know he's done single turbo engines.

 

http://www.toysport.com/technical%20...tech_notes.htmOf course this means lots of money. What I want to know is how early of a 22r you need.

 

well i didnt read all of the answers to this so im gunna just put in my .02$
i have the same truck ('84 22r 5spd 4" 33s) exc. that mine is bored .030 over, i hav a mid range cam from north west off road, head polished & port matched, header from downey 2.25" exh. and 4.88 gears my truck will smoke the 33s on the asphalt. and will climb any thing.
if you want good highway performance gears r a MUST 5.29 for 33s on the highway (detter gas mpg & driveability). if you want performance go to LCEngineering.com they have the parts or they sell a create 22r that makes 400+ HP carbed.
also check out northwest offroad & downey

 

or 2jz-gte maybe a lexus V8
