My friend owns a 1994 4runner 3.0 auto 4x4.He's a city boy that thinks he's country never been wheelin in his life, never even had fried chicken!!Anyway he wants to know what mpg he will get if he lifts it 4in and puts 33's on it with 4.88's.Let's not stop there he wants to rebuild the motor using a gold kit from RPM Machine,Megasquirt,a cam from toyotaperformance (18-1561),DOA racing throttle body,ported intake and plenum,ported intake and exhaust runners,shaved heads,bored .30 over,3in Downey headers,3in pipeing with high flow cat,and cat back flowmaster exhaust.He wants to know if someone has made a progammer,chip for the 3.0, and a shift kit for the auto.Plus how much it would cost.I'm interested in this as well.I told him about 4-5k but he says its 2-3k for everything he wants to do.Any help would be appreciated.

I'd say don't waist your money and swap the engine. 3.4 a popular swap. I bevieve there are some other more complicated v8 swaps out there if your really feeling the itch.

He wont even think about a swap im just interested in the gains.

We were just talking and what about adding a turbo on the 3.0 but dont run it off the exhaust run it off a snorkel.

just a 22re

not running a turbo off the exhaust??? and run it off a snorkel??? how do you do that never heard of it

Banks does it on one of their race trucks its just up under the front bumper.Going to read up on it think about it if you put in colder air you make more power and it's forced cold air!

Alrighty, first problem: Gearing. 4.88's with the auto are fine for 31's. Those who have geared down to 5.71's for 33's report good impressions. Without gearing, which will be like another 1200 bucks (plus locker ~ 3-400) the engine mods are worthless. However, even if he doesn't touch the engine, this should be his first mod along with tires.

His MPG will suck. Period. But doesn't all of ours? That's just how it is when you lift and enlarge the tires. The added mass and drag kill economy for the sake of off road performance. All those engine mods will make more power because they will allow the engine to use more fuel. If he gets low teens mpg driving gently he'll be doing well.

I'd say this is a $5k minimum and when you are done you could have installed a supercharged 3.4 which will produce more power. BTW, people with the 3.4 are reporting better fuel economy over the 3.0 even though the engine is larger.

4" kits are not really the best off road either. They have a tendency to bend/shift making for frequent trips to the alignment shop. He might search the bbs a bit, there's lots of discussion on it.

But, engine building can be fun and we might all learn a lot from his work so as long as he goes in with the attitude that he is in the engine for the experience, cool. Have at it. He might just surprise us all.

That 4runner better have a spotless body if you are going to throw that much money in it. If he is all about squeezing performace out of engines the 3.slow is not for him. Save your money and buy a 3rd gen.

Well its been keyed twice (my friends an *** to everyone) the paints fading and theres something seriously with the wiring (when you try to turn off the alarm using the remote the lights turn on and off,it trys to start its self,the windows roll up and down,the windshield wipers go back and forth on high and the door locks lock and unlock).Hes got 2500 i told him to just pull the entire wiring harness and swap in a 3.4 but he wont do it.Oh and hes not going to be going offroad he just wants the look!!!!!

Well this friend seems to have it set in his mind that he is gonna polish the 3.0

Let him know that an exhaust alone will cost him over 1,000 ( with headers) and 3" is way to much by the way. If he does ALL those mods, perhaps a 2.5" exhaust will be just big enough.

He won't get much power from this engine, so im gonna put a rough estimate at around.... 5 thousand plus. For 2500 bucks you could find a used 4.3L chevy v6 and that will be able to pull the truck around fine.

You can talk to Downey, who'll set you up with JET, who'll program the chip for a 15-17 hp gain for $310.

all that stuff is a huge waste of money! 2-3k is not realistic the 5k number is, unless your getting wholesale/dist cost and doing the work yourself.

2nd a turbo, is an exhasut driven supercharger, basically. so if youre running off belt ie always on vs needing exhaust gasses to get goin (hence turbo lag)
neither is suggested on that 3.0. SWAP IT!!!

if your buddy is serious for power, the only real option is a swap and the 3.4 is the easisest from what i gather. go chebby v8, ford 6 or whatever but any of the good swap options will yeild 2-3 times the results you seek out of all that bolt on gainless mods.

also, all that will take the reliability of toyota and send towads the reliability of....well....lets just leave that one alone.

why can't you just be happy with what you have?
hell buy some wax and make it shine.
use good oils and filters
keep it clean
rims and tires
speakers?
why do you wanna do so much when you could sell your 4runner for 2-3k, use the 3 you got saved up, and buy a nicer one.
since my 3.0 is in mint condition, i suspect ill end up swapping the engine.
i love it when you can stick a fridggy magnet on the truck hahaha.

Well im trying to talk him into a swap.I think hes starting to understand that theres no way to get power out of the 3.0 without putting MAJOR money into one.I know theres a build thread on here that takes a 3vze and a 3vz-fe and combines them I'll have to find the link though.Oh theres is someone who put a mitsu turbo ona 4runner on cardomain here it is.

you dont need to talk him into n e thing.....just let him know the facts....if he wants to waste his cheddar, dats on him, u did your part by letting him know whats up!

Thats true but I dont think He should just throw all his money away.

Ball joint spacers and some adjustment on the torsion bars will yield about 3" of lift and I put Cruiser coils in the rear. Slightly higher in the rear but now I finally have articulation!

As for power - dynos measure power at the wheel. Once you put a heavier wheel/tire combo you are effectively decreasing your power and on top of that you take the engine out of its powerband. He will need 5.29's for sure and 5.71's are a good idea. I think the 5.29's will work great since most 33's aren't truly 33" tall. He should increase cooling for the auto tranny and maybe play with ignition timing which is free. Anything else is a waste of money. A flathead Ford is easier to tune than the 3.slow. We've all learned to live with it and accept it as a lot of these engines are approaching 200K miles - there is some longevity in not being able to spin those parts faster.

And as mentioned: a supercharge 3.4 is a better idea than throwing all that money into the 3.0.
