Tacoma V6 versus 4Runner V6

Does anyone know why the 4Runner V6 is a 4.0, the same as the Tacoma, but has over 40 more horsepower and 10 ft lbs of torque? Is there a cheap mod or any other mods you can do to get this much. I have a brand new 2011 DC LB V6 auto. Thanks. Tried looking at the threds for this info with no luck

I'd imagine DT headers, URD intake, and straight dual pipes could get you a pretty good boost up there. Yeah its def the variable valve timing though on the 'runner engine giving it so much more power.

Both the 4runner and FJ cruiser get DUAL VVTI, instead of just the standard VVTI on the Tacoma engine. No idea why they don't offer this on the the Tacoma. I'd guess to keep prices down since 4runners start at like 29k with no options, although FJs are in the 25k range so that doesn't totally make sense either.

It's because they are way heavier than a Tacoma

 

Thanks for all the quick replys. I'm new to the site as I just bought my first Taco. 2011 DC LB Magnetic Gray. Only issue so far is a SLIGHT shudder when punching it from a stop. After research i determined that it's probably due to the two mpiece driveshaft wobbling at the carrier bearing. sounds like a lot of others have this issue, although it is minor. Just figured Toyota would have figured this out after 6 years of the GEN 2.

 

They sold a lot of Tacoma's over the pass 5 year so I don't really want to change something that's been selling, (that's what I think)

 

It could be the driveshaft issue, which some have fixed with the tom woods single piece driveshaft. But since your totally stock, it might also be that the transmission reflash TSB could fix this. My dad's 08 had the shudder til he got the fix. Not sure if this affects '11 tacomas though. My '10 hasn't had the shudder so far.

 

And 'tuning'...computer mappings will have a major influence on power output.

 

I would not straight dual this truck unless you are going to forced induction. Exhaust scavenging is far more important than outflow for an NA engine. If you separate the two banks...You mess with 1/2 of each pulse per side...

... ^^^ ... this was exactly the problem that was happening when the OEM TRD Duals were being put on the 5.7 Tundras by the dealers.

It happened to my 2007 5.7 ... a loss of power (primarily on lower end) with the TRD duals.

However, my "butt dyno" overruled that, especially with the better muscle car exhaust notes (not too loud and not too soft, just right in sound & DBs).

Yep, these newer engines (especially the NAs) need to scavenge that back pressure, unlike the exhaust of old.

Disclaimer ... I am sure that there are some exceptions to the "exhaust scavenging rule" ...

We have a 2010 4Runner and a 2011 Tacoma. I believe Toyota left the Tacoma engine the way it is because the torque comes in a little earlier than the 4Runner/FJ but not by much. (300-400rmps)

 

As previously stated you will probably see dual VVTi on the redesigned Tacoma. The current Tacoma 4.0 has a fair amount of torque and that is a pretty significant thing when you are talking about trucks.
