Don't junk the truck or the motor, they're both a great setup!!!!
What other symptoms is your motor showing, aside from a lack of power? What size tires and gears are you running?

What is the aspect ratio of your tires? I'm trying to get an idea of the circumference, the amount of drag and what your final high-range gearing is.
Don't lose hope on that 22R engine. They really are great motors! Heck... you might consider taking your truck to a mechanic and letting him tune it. That would be cheaper and a lot faster than putting another motor in the rig.

| tires are pretty much a stock tire that came on toyota trucks is about like a 28 or 29 inch tire real small, got my stock cam going to put it in tomarrow . if it dont fix it i dont know what to do,its got 155-165 psi on compession test,people have told me thats good compression. if there is any thing you can think of that might be wrong let me know and ill go check it. thanks for your reply pie |

Compression sounds solid for that motor. I've seen it a bit higher after some head work was done, but that sounds about right.
Did you change the carb on it, or is it the stock carb?

| dude when i got done rebuildin my motor it had no power either. actually it still doesnt have any power. my guess is that you put an rv cam in it somthing to get you that lower end torque. you can feel the torque and power but then its gone there useless. my guess is if you put the stock cam back in it would feel more peppy. the reason being that the motor was meant to make more of its power at the topend thats with almost all 4cyl there just not meant to have much of a lower end. so when you need that power maybe to get you rollin a little faster in 5th gear its not there because you are already out of your power band. yet this is only what i have experienced in my truck. and i only could really tell that i had the power still there but at a lower rpm is when i put the 5.29 gears in my truck. now its like a semi i have to shift years so fast cause i am gettin out of the power band and it is only became noticable to me when i went with a deeper gear. if you do have the same set up like me you have a motor that likes to be dogged. my motor hates the high rpms just hates it. but when i am doggin it under a load it seems to just keep pullin and the motor seems some what happeir its weird and i believe it all had to do with that rv cam. this is once agian just my experience. |

| but it pulls in 1 and 2 gear if i go up a small hill at 30 mph in 3rd gear it bogs down and want pull it it cant be pulling 3000 rpms . i cant use 5th gear . bogs in forth in some places no power at all before i could bog the motor in 5th and it would still pull, now it cant. got to gear down.before i could pull the mountain in 4th and 3rd gear now its 3rd and 2nt to the floor its gutless. its a stock carb right now too. |

| it could be the header but i doubt it. if you had power befor the rebuild but no power niw. then somthin you have added has changed where the power is at. the header could be taking away from the torque. maybe the manifold gives you better torque somtimes. i am not sure. |

| put stock cam back in it and it got all my power back, think it was the wrong cam or a bad cam going to check it with a mic and see if it was the right cam. |

| i got mine from mad dog racing,it feels like it has the same power but pulls freer it want pull any fasterat high rpm but will pull. for ex. before the rebuild i could go up my roar at 45 mph in 5th gear lugging itand it starting to speed up. with the rv cam it would lug in 4th but not speed up at all, like i lost a gear. and on highway before it would go 80 mph with out bgging with the rv it would do 65 in 4th gear and when you went to 5th gear it would bogg down sounds like 1800rpm( you know when you bog and need to change gears)and go to 55 mph. now it well go to 80 in 4th and 5th gear well hod the speed and even speed up.that cam killed power completly tru the rpm range. |

In my humble opinion... I would go with a rear locker first, then do the front locker later (and get a selectable locker). Here is my reason...
- Get to know your rig first. You've made some significant changes to it, and it's going to wheel a LOT differently now. Get to know its quirks, and more importantly, its limitations (how will it side hill, how stable is it on steep grades, what happens when you climb a steep ledge off camber, etc...). If you learn how to wheel your rig with limitations first, you'll be a far better driver when you add a front locker later - and a WHOLE LOT safer too.
- Front lockers are a bit tricky to deal with the first time you get one. They will push you right through a turn when you're wheeling a light vehicle with a light-duty axle. The big trucks with hyraulic steering and heavy tires can overcome most of it, but for the lighter vehicles, it's a whole new ball of wax. So... if you are running a full time locker, you'll hate life as it's about impossible to turn the steering wheel when the front axle is loaded up. You'll fight it and it gets tiring, really quickly, thereby ruining your off-road experience.
- IFS and front lockers... boy, where to begin. The long and short of it is this - Your Toyota IFS front axle won't deal really well with the stresses that a front locker will throw at the CV Joints. And, when (not if, but when) a CV gives out on the trail, be prepared for a several-hour fix, if you've brought spare parts. Worse case, you'll blow out the side of the differential and then your totally hosed.
- If you are set on doing a front locker in your IFS axle, then definately get a selectable locker and be sure to turn it off, more than you turn it on. This will prolong the lift of your axle and make your wheeling adventure much, much more enjoyable.
Anyhow, those are my thoughts.

| ok let me put in my opinion which also came from rick when he was my neighbor in all but i didn't listen strictly a know it all at once teenager. i went ahead and welded yes welded the front spiders in my truck when it had IFS. now i was planning on replacing it with a staight axle anyways. so it wasnt that big of a deal but i took it wheelin twice like that and let me tell you what it sucked like a 2 dollar you know what. you cant turn at all you can just give up on it when you are locked in 4 wheel although it is good in the mood but you are still arm strong steering. then when you are trying to climb a hill you are all over the place it actually made me goes less place than it did when i had an open diff in the front. manuverbility is way better than traction at somtimes. on top of that you have no flex in the front barley at all so it isnt like it does that big of thing 4 you at all. putting one in a straight axle is even worse. take ricks advice unlike me dont do it. an arcticulating suspension and manuverbility is a hundren times better than having a front locker. o and when i took the front end apart to put the straight axle in the cvs were completly shot they wouldnt have lasted on more trip. do the right thing and learn to wheel with out a front locker it has taught me alot. thanks rick |

yeah, a posi would work fine. You'll still have to fight steering a bit, but not nearly as bad. You may have a hard time finding a posi-traction unit for that front axle though.

The TruTrack is an AWESOME device, especially for vehicles that have less than 300HP engines. Just put a bit of pressure on the brake pedal and the front end locks up quite nicely.
The TruTrack works as a moderate limited slip unit all of the time, and a locker when you put pressure on the brakes and gas at the same time. I run an e-Locker in the front of my FJ40 and wouldn't trade it for the world. Hell... I've wheeled some of the toughest trails in the U.S. and hardly ever flip the switch for the locker portion. It's just as easy to put a bit of pressure on the brakes and then give it some gas.
