I have a 4 runner with Chevy 1 ton axels on 37" tires. 538 in the axels. I just put Lc engineering header and 2 1/4" exhaust and intake. What should I do next to get the most power out of this motor? I need more power bad!!!

 

Welcome. I'll go ahead and say you need more motor. You will spend a lot of money to get power out of a 22r. V8 swap might be your best bet. What is the truck used for?

 

Brother you have 4 mice in a squirrel cage.

The R series of engines is not the answer your looking for. Sorry

 

It's a great motor but its known for its reliability not its power output. If money isn't an issue you can get and after market head with larger ports then port it put a cam in it. Maybe stroke the bottom end. Then you might have 4 pissed off mice in a squirrel cage but still just mice. Maybe a sbc or a large v6 swap might be more what your looking for.

 

Dont listen to them. You are on the right path. You got the good header.
Cam or head and cam combo is good for alot of power.

With engnbldr rv head...268 cam...and lc header....mines got tons of poop for a 4 squirrel motor.

I'd put $100 on it dusting a V6 runner. Probably a turbo runner. (not a 3.4)

Not everyone wants to hill billy up there rig with a 350.

a well tuned 22re has all the power you need to wheel anything with proper gears.

Too much power...v-8 ....you will tear a toyota to pieces.

 

Yes that is what I am getting at!! My double transfer cases has all the torque I need on the trail. I just need a little more poop for riding in 5th gear on the high way! I am not building g a drag rock Krawler, lite weight is what I want. I heard there is something I can to on my mass air flow sensor to change the way it works. Our mass airflow's slow down airflow in a major way, supposedly there is a better style that may get you about 15 HP?

 

If light weight is what you want why do you have 1 ton axles with only 37in tires and a 4 cylinder?
You could try searching around for build threads on the 22re and see what works and what doesn't.

 

I've never heard of a upgraded air flow meter to gain 15 hp. That number might be a combo of a bigger air flow meter with intake exhaust and maybe a camshaft.

 

gearing is the key regardless of horse power / torque, however small motors do have limits.

 

Sorry if I miss spoke when I recommended a sbc but when someone says major power gains that to me means 50+ hp gain and that muh is fairly uncommon on a 22re with out major mods and a loss of the famous reliability of the 22re. It will still be reliable but probably not 200k in between head gaskets. Keep reading and searching lets us know what you do

 

I love the 22re, but it's not a long term solution for your needs. You will just be lugging it too much with that drive train. Look at what you've already done and your still needing more...

The 3.4 5vz-Fe will get to where you need to be.

 

So yourself a favor and inspect Lc's site and inspect that mod. They take a mass airflow meter from a newer Tacoma that doesn't work with the doorway like we have it uses a heat sensor that is cooled by airflow to give less restriction and better mastering of the air going into the engine. It also cones with a programmer to tune you computer . Gain is 12-15 hp

 

check out LC's site, better airflow meter from newer Tacoma with the ability to tune fuel and timeing. 12-15 hp

 

I was unaware the the 22re ecu was programable. Be interesting to see how these work over the course of a few 100k miles. Thanks for the info.

 

curious as to why you put such big heavy axles in your truck in the first place? built toyota axles are more than enough to carry a small light truck around on large tires with proper gearing and and a solid 22re with out robbing all the power before it gets to the tires. my friend is running a worn out 22r on 38.5 boggers using 5.29 gears and does fine, not awesome but fine.(the motor is really tired) offroad he uses 470 gears in the t case and crawls without effort, all on a toyota drive line with out any breakage. usualy big axles are used after a big motor is installed and the toyota axles are failing under heavy demands. im not bashing your build im just curious on what your trying to achieve.

 

One main thing with the full width Axel is stability and width. That is what I was trying to achieve, and I did the truck just flat out looks great and wheel amazing. Looks was part of my build. I wanted it to have the axels sticking out of the fender wells for protection from rocks, trees or whatever.
