Performance Upgrades
I was hoping to start a discussion on what type of Performance upgrades everyone has put into their 4th Generation Toyota 4Runner.
I currently have a 2006 V6 4Runner Sport 4WD. Just put on a 2.5" OW Lift w/ 275/R70/17s and XD Revolver wheels. Next month will go on the Shrockworks front bumper and winch and PIAA lights.
Is anyone out there using a aftermaket exhaust, Air Intake, or performance chips to up the game?

Really the only way to get good power out of the V6 is two ways
1) Forced Induction IE Supercharger/Turbo
2) Build Your motor.
I am planning on building mine as I near 200k. The 4.0 has some good potential. Throw in bigger cam, stiffer valve springs, balance, and your talking good power. Ive been told anywhere from 20-25% increase in hp.

AFE intake or the new air aid one, URD maf cal, long tube headers, DONE. if you want to get boosted I'd go the the URD supercharger unless your going my route for a turbo but it'll take a lot of fab work and down time.

NO...because they are pretty much worthless. At best MARGINAL improvement. All they do is make the company selling them richer and the people buying them poorer.
The only aftermarket improvements that really work is turbo or super charger.

The problem with doing that is if it gets anywhere near a 20% hp increase...it probably won't meet EPA emissions. If you're not worried about that..OK. Also full racing or even half racing cams...they idle like crap.

What size cam constitutes a "racing" cam? I ran a 223/224 112LSA in my old truck, an while a mild cam it really woke up my engine. Combined with a custom tune and full exhaust and 2800rpm converter she moved pretty good.
However if I drove it like a sane person it was near indistinguishable from a stock truck IMO.

The place im taking my engine to be built is in CA. So Every engine they build must pass emissions. Im not getting racing cams. That would be like a stage 3 or higher.

I'm sorry that is incorrect. If you buy an intake alone then there is some truth to that depending on how well designed the intake boxes are compared to the factory. Now if you combine say an intake of good quality, revise the exhaust system, and tune the vehicle to compensate for the volumetric efficiency then you will get a good bump in power but it won't compare if you get boost. And even then the same mods will net better improvements with boost.

i run stock everything even the air filter but pulling out the hydro carbon air filter helped a bit for me!
hydro carbon air filter is that great looking filter that is permanently on the vehicle just pull it out!

I know that you have a very hard time using computers...but could you please TRY to show me someplace on the internet where some actual independent testing has been done that show there has been significant improvements with these kind of mods. If there are the 20% improvements that have been claimed then this can easily be found...even by you.
If there were any significant improvements in performance then Toyota should fire all it's engineers because they are doing a lousy job.

I gained a 20-30hp increase from a 93 octane tune with EFI Live on my LQ4 6.0 for less than $150. Sadly those tuning options aren't available for Toyota engines unless you run stand alone management from what I've gathered.
The factory ie Toyota leaves a lot on the table from a performance standpoint to achieve better reliability and pass strict EPA standards. Granted things like CAI's and throttle body spacers are worth little more than a paper weight, but to say that anything short of forced induction is a waste is completely asinine and juvenile.
I've said it before and I will say it again Mike, leave the talking to the adults.

And also please inform me what a "racing" cam is? I didn't dyno my truck but it is a proven cam profile to make power and maintain street ability. Since you're so proficient in using the Internet as you claim I am sure you can find some data on that particular cam shaft.
