runner vs. pickup
What is different about the 3.0 in a '92 4runner and a '92 pickup?
Reason for the question is my father-in-law has 2 3.0s. One had a blown motor when he got it. He bought a flipped runner and pulled the motor out of it and placed it in the pickup. I've got a '92 3.0 that runs fantastic and has about all the power I'd expect out of a 3.0. I have 31s.......he has 30s.
He can take his truck.........get the RPMs wound up and roll the rear tires when shifting from 1-2 and 2-3...........neither of us can get mine to do it. Honestly driving his is almost like drive a smaller V8.
We both thought the motors were the same................are we wrong?

the truck has no weight on the butt .... your 4 runners have twice as much weight ....
if he keeps treating his motor like that it's going to become much slower than yours seems to be

you're kidding right?
first, compare axle weights on those vehicles. you'll find the 4runner is much heavier on the rear axle. so it's going to be harder to break the tires loose.
second, you have different size tires, yours being larger. that's like both of you being on ten-speed bikes, and one of you is starting off on the big front sprocket while the other is on the little front sprocket. so your gear ratio is cutting into your available torque, making it harder to break the tires loose.
combine the two factors, and yes, it'll feel like they're different motors.
now tell your dad to stop doing burnouts.

First - of all...........in-law
Second - I understand the difference in the 2 vehicles but we are no comparing 2 different vehicles.........we are comparing 2 identical '92 extend cab pick-ups. One has the stock motor and one has the stock motor out of a '92 4runner. I'd understand if we were comparing 4runner to pickup but we aren't..........we are comparing 2 identical trucks.
Third - gear ratios are the same........already checked
Fourth - his tires measure 30" dead nuts, mine measure 30 13/16"
Fifth - he isn't doing a burn out simply dropping the clutch at a high RPM........you want to see a burnout I'll get one for you on tape from my Duramax
I understand what ya'll arer saying..........but it doesn't make sense if the motor are the same. Maybe it is by chance but still odd.
Thanks!

gee, i'm sorry; i read "runner vs. pickup" and for some crazy reason I thought you were comparing a 4Runner and a pickup.
the 3.0 motor used in all of 92 was a 3VZ.
that said, consider this from Wiki:
The 3VZ-E is a 3.0 L (2958 cc) version. Bore remains at 87.5 mm (3.4 in) but stroke is pushed to 82.0 mm (3.2 in). At introduction output was specified as 145 hp (108 kW) then later bumped to 150 hp (112 kW) at 4800 rpm with 180 ft·lbf (244 N·m) of torque at 3400 rpm.

im gonna guess your engine has been beaten on and is tired and your father in law's was taken care of? different driving styles and milage make a difference and yours must be tired. my friends 4runner has 350k km's no rebuild and its tired as hell, on a good day my 22re can beat his runne, and just looking at his 4runner you can tell it was beaten by PO. so thats the only thing i can see here. does his have any mods? rebuild?

you may find a solution to your confusion by doing a compression test. maybe you'll find a weak cylinder on the one motor. is everything else consistent, like stock intake and exhaust diameter/muffler type? just trying to think what else could be cutting into your power.
you could try swapping the tires on the back. maybe it's as simple as tire composition.

tried it with smaller tires before I put the 31s on and nothing.........
everything is stock on both except his cat is deleted.........so that could be some but I don't think it is that much

Check timing on those motors. I wouldn't be surprised that the one you think is faster has had the timing advanced. i noticed a HUGE power increase when i advanced my timing.

NOW WE ARE TALKING!!
His CEL keeps coming on and the code is for something about the motor running lean....which may explain the need for higher octane.......
Now, explain to me or point me in the direction of how this is done and how it works please.
Thanks!

i was going to post some links but there's a crap load, so you may want to read them all for a good round dose of advice.
do a GOOGLE search for toyota 3.0 timing advance.
when you advance or retard, you are manipulating when the spark occurs in relation to where the cylinder is in its stroke. ideally, right when the cylinder gets to the top and about to cycle down is when you spark the fuel. but realistically is not ideally, and your truck runs 10-12 * advanced. you advance too far and you may ping (predetonation). to deter ping, you use premium gas, which has additives to delay its combustion.
read some of the stuff in that search and i bet that's probably the solution to your issue. soon as i read RE-RE's comment the bell went off in my head.
put a timing light on both trucks and see what they say.
