I mean......at least it would have reached 88mph....
Is there anything we can do to bumb the performance on the 4.0?

codes? I think you mean ECU tune and dyno results. There really isnt a whole lot of coding involved just changing specific values in AFR, timing, yada yada yada
There is so much involved in taking an NA motor to a FI motor... especially if its a motor that normally doesnt have a cult following (read: LS1/2/4/etc). Its a little more complicated than bolting on a small turbo or a single screw and calling it a day. Without the right tune you will blow your motor. The engine probably isnt built for the amount of compression required to run a significant amount of boost.
With that said... if you allow your car to breathe better (intake, exhaust, headers) and follow up with some engine management (vehicle specific tuning) on top of some weight reduction (no sub woofers) then you will see some HP/TQ gains.
I dumped nearly 20K into an STI and went from factory 283HP to 400HP. Its NOT cheap and marginally worth the asspain. A simple header back + intake will give you a little more performance without the butthurt.

I know a few things about turbos.....
That's my track and fun day car. Thanks "son"...
is that the factory TT or you boost it after?

Cue philsey to correct all the spelling and grammar and we'd have another full circle "Performance thread".... Even the smart @$$ comments are the same (still laugh though!)
Oh and OP if you searched and saw there was no supercharger, surely you saw threads that looked exactly like this one. Devolving into "It works!" "No it's just a noise maker" and "Regear" or my favorite "Did you not test drive?"
:fro:

Maybe Toyota could go back to the future and give us this or say a 76 series! lol.... Even Marty Mcfly could see in the future better than Toyota!
could bring this back as well!
Anyone else see this?

And how might you intend to remap the ECU without the codes....?
I love these threads.
"Man I had a LS, turbo, tuned, cammed, y piped, catbacked, supercharged, hemi, ****in racecar that I dropped a million dollars into and that shit was so fast mang."
Never did any real Dyno testing just seat of the pants. The mileage went up and the power was noticeable. I did not loose any low end. It just felt and sounded much better. Can't remember the cost back then.
All the 3rd gen RX7s came with the 1.3 TT motor. This particular one has had quite a few changes over the years since I bought it in '97. :gossip:

The biggest single thing I personally want - 4.10:1 gearing option. That would be ideal for me and I think for most of us with stock to 285 tire sizes. IMO 4.56 is too low for overall performance on the highway, but 4.10 would be ideal and 4.30 would be a nice option as well.
There are superchargers for this engine BTW. You can google Prado 150 supercharger and find them. They only offer about 50-75hp boost, and IMO it's not worth it for $10k. Just buy a GX.
Where I think you might find some swap potential is through buying a complete wrecked GX460 and swapping the full drivetrain. My guess is that it'd be damn near a bolt in swap and the ECU would be plug and play. But again, might not be worth the effort for small gains. A 4.6L turbo v8 could be a very interesting build, but probably pretty $$.

I love them too. "These trucks are as slow as molasses flowing UP hill in the middle of Vermont in winter! But since there is no aftermarket for them, let's bash folks asking the community if there is anything we can do to get some more ponies out of it"........
Thanks. I did see some info, but for a truck you're right, it's not worth the huge money for just a few ponies. We looked at the GX too, and it did have a little more HP. but for the cost and for the loss of it off road ability, it just wasn't worth it either. It got pretty terrible mileage as well.
I think THE swap would be taking that same motor that they also put in the Lexus cars but it has direct injection and 40 or so more HP. Of course that would mean ripping the motor out of a brand new 4Runner and finding a brand new Lexus motor and putting it in... $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ :wow2:
Thanks. With a truck, that's all that really matters I think. Does it feel a bit more powerful? It's good then. Appreciate the help.

You need to realize this exact question comes up every week or so and the answer is always the same. There's only so many ways to say nothing realistic can be done. Sure there are pie in the sky solutions but you might as well have just bought something fast to begin with as the cost would be astronomical to make a fast 4runner by swapping engines, not to mention it would then have the reliability of a Jeep if you were lucky.
Since you obviously race (it seems every one of you with this question does and they post pics to prove it) you would know the simplest and cheapest solution to making a 4Runner fast is to strip out around 600 lbs of interior and put on smaller diameter tires with lighter wheels. Of course this defeats the purpose of having a SUV but trying to do the engine and drivetrain mods defeats the purpose of having a Toyota. .. reliability and durability.
I'll post a picture of my FJ too so you'll understand where my pain is coming from.....

find a wrecked LX or LC, drop in that 5.7

Sort of...
The 3UR-FE will fit, but then you'll want to swap the transmission and the transfercase in as well; otherwise you really have to mess with the ECM/Modules as they control both and are programmed for both. Then there's the question of how well the drivetrain will hold up to the extra torque that the 3UR-FE drivetrain has (and to be honest if you have a donor LX chassis you may as well go with the beefier axles anyways.) Finally you need to consider all the CAN communication and modules because you cannot just "hack" the ECM and tweak it like most brands, so you need to plan it out correctly so the vehicle actually operates correctly.
Theoretically you'd only need the ECM, 4WD Computer, and possibly the combination meter itself. Though there is a possibility that the Skid Control ECU will not play well with the 3UR-FE as well as other ancillary systems.
It's not super easy, but it is doable and I've been thinking of how to fit a Supercharged 3UR-FE drivetrain in my 4th gen.

It would almost be easier to just buy the GX or LX and drive that or try to retrofit the T4R body on it.

You can get 4.10s. They're Toyota OEM, I think they were actually standard on the 4 cylinder 5th gens when they first came out. (Did anyone actually buy one of those things...?)
In my research I read a ton of threads on 4.10 vs 4.56 swaps mostly on FJ and Tacoma Forums and the general consensus seems to be that the 4.10 is not a big enough jump/improvement over 3.73 to warrant the cost.
I just keep reading Jeremy556s posts regarding gears and honestly have no good reason for not having them on my truck yet....Soon.
Easy tiger, I wasn't referring to you and I was only poking.
If you "love them too" then I take it you've read them before?
I've read many and I will echo the same thing that has already been said, the only real worthy investment is gears. Which are next on my list.
That said I honestly do feel your pain. I have often wondered how it is that the 3.5 liter vq35 in my Z car puts out close to 300 HP, and the 4.0 liter v6 in the runner is only 270. As mentioned I'm sure a nice Dyno tune would do wonders if someone could just hack the ECU.
Tell ya what...I am taking the 350 in for a tune a tuner shop in Houston Called Jtran when I get home. (not for another 6-8 weeks I'm afraid)
He is primarily a Nissan guy but they do other things too. I was thinking about asking him if there is anything he could do or try on the runner as far as tuning goes. Who knows? FRS's are huge now, and maybe there will be some avenue through software developed for Scion.
I will ask about it when I am in and see what they say.
There how's that?

The 5th gen rear differential is not compatible with gears from other 8" or "8.4" toyota differentials. There are only 2 factory ratios that have ever been offered in what's called the "8.2". Those are 3.73 and 3.93. There are only two aftermarket options - 4.56 and 4.88. This leaves a large gap between 3.93 and 4.56. I do not know enough about these differentials to know if one could modify an 8.4 ring and pinion fit, or possibly even use an 8.4 pinion in the housing and a custom ring gear - although IIRC most are sets that are machined and polished as a pair so maybe not? I suspect it would be cheaper to build a hybrid axle with a LC 9.5 center than mess with custom 1 off gears. Or since the new Tacoma likely has the same abs sensors and an internal e-locker, if they end up with any model having a 4.10 gear ratio that might be the easiest swap, but you'd end up with drum brakes
Toyota offered a wide range of gears for the standard 8" differential. So many that there are both 4.10 and 4.11 ratios (41 tooth ring, 10 tooth pinion, and 37 tooth ring, 9 tooth pinion). Basically if you can imagine it, you can probably get it in an 8". The 8.2 is very limited so far.
