Is there anything we can do to bumb the performance on the 4.0?

Searched the 5th gen subforum..... Had the FJ for 4 years with no luck... Exhaust looks like the only thing on the market at this time.

Has anybody had any luck bumping HP on the 4.0??

Install the TRD Supercharger. That's what most of us have, and it works wonders. My 4Runner can run the 1/4 mile in under 10 secs
 
All joking aside, only real performance mods available are intake and exhaust. TRD has scrapped their supercharger program and has been unwilling to release any of the ECU codes making it difficult to get a viable aftermarket option.
 
Speed costs money son. How fast do you want to go?

If you have some deep pockets take it to a pro and have a custom turbo put on it. It will cost a bundle but you will have more than enough power gain to satisfy yourself.

My girlfriend has a 2015 Ford Edge Sport with the twin turbo 2.7L EcoBoost @ 315 HP/350 ft lbs torque.

Trust me. That little crossover flat shits and gets with it. I have driven many V-8's that seem lame compared to it.

Why am I talking about the Edge? Because if Ford can squeeze 315 HP out of a tiny 2.7L motor even a mild amount of boost on the 4.0 Toyota will put it well over 300 HP with no internal mods.

But... You are going to have to drop some dime and time to do it. ;-)
 
With production of the 4.0 wrapping up , I don't see much future for performance parts either. Like some have said , gears , maybe a catback . I don't think the intakes do much but give it a try.

I don't disagree that Toyota couldn't squeeze out more power with a turbo, or turbos, but reliability is key. They have a solid motor in our trucks as it is now. I would take reliability over speed any day. Ecoboost is cool, but it seems like most of their stuff has bugs and issues, more electronics to worry about, and more mechanical shite to break down.
 
Gears and Y-pipe other than that the rest just makes noise so you think it's faster...

Good point about the Y pipe . I totally forgot about that. I had the URD Y pipe on my 05 and it was awesome. I was looking at Doug Thorley for my new one.
 
Fug that! I will take my piss poor 4.0 vs a motor that is known to drop valves!

They don't drop valves. I've owned and raced several. They are just about the best petrol v8 you can find. The simplicity of them (plus the best in class engine management) is what makes them so genius.

The 4.0 has plenty of potential, but we will never see it due to the fact it is a Toyota with 0 aftermarket tuning support.

I agree with what has been stated before. You can gain some usable power with gears and a Y. pipe and that is about it. If you need more han that... don't get a 4R

Quick question I know most exhaust if not all of them for the 4Runner platform is mainly for Boise but is there a way to have the noise and not change the torque curve as far as losing bottom end vs gaining top?

Sorry but even GM admitted to failures it not some BS it's just a fact! Other than that I am still an LS fan!

I know a few things about turbos.....
