How do I get more HP?

I have an access cab 2008 tacoma, 2.7 4 banger with 265/70 cooper discoverer mud tires installed. I have a K&N cold air intake which helped a little bit. I live in WV.....so I go up and down mountains constantly. My larger tires cause me to not have enough power to make it up these hills and I lose alot of speed. I know I could get a better exhaust system, but anytime you hear the 4 bangers with an exhaust, it sounds like a pissed off bumble bee, or a suped up weedeater. I do NOT want to change the gear ratio either. I would really like to find some sort of computer chip that actually works that changes the mapping in my computer. If anybody, who has a 4 banger.....knows any way to crank out more HP, please let me know.....Thanks.

ditch the K&N, wait for a supercharger to be released and search around in the Performance/Tuning or the builds sections.

 

Doug thorley headers seem to be the best way. If you add up a cai, rmv the 2nd filter go synthetic oils ... everything but a supercharger, the headers ,from what im hearing , get you more hp than the rest combined. I like my 4banger, but after all u can gain, it will still be a 4banger, with just a few more hp.
I want my headers! lol

 

Let this guy help with the horse power

 

Only proven methods are to get new header or slap a supercharger on it. That nickel and dime crap won't get you much.

 

yup, fun to tinker with though, i cant tell 1 way or the other if the 2nd filter pulled did anything. I wish a cai and a performance muffler would get me hp on my 2.7, but I haven't actually seen a dyno chart showing the 2 getting say 2,4, or 6 hp gains.

 

they make a turbo kit that boosts your hp up tp about the same a a v6 trd tacoma... always run the risk of blowing a motor with turbo though... maybe trade it in for a v6? i had a 4 banger jeep wrangler that was lifted and loved it except when going through West Virginia... too many hills too little hp. RIP 95 Wrangler!

 

Rumor of a s/c for the 2.7 , from URD have been around, i like the idea of a mild setup with minimal modding what little i know about them , I think 4psi would work.

 

SEARCH

 

"search" is how URD and s/c keep coming up lol. On the other hand "search" can get u any answer u want... then truth becomes the victim.

 

Some of the suggestions above will cost more than if you just trade it in for a V-6 .

 

what he said!

 

lay off the gas

 

what gas.. my 2.7 doesnt seem to use any

 

I would like to get a v6, but I drive 2 hours one way to work. Not only that, I would hate to buy a new truck because I work on a surface mine, and the roads on a strip job beat the crap out of a truck. I already have around 60K on my truck, so it is already broken inn. It seems to be impossible to get more HP without losing mileage. Maybe I should just put the extra money in my tacoma and just not take it back and forth to work. I should just buy a used car that gets good gas mileage and take that back and forth to work. Well, are there any other ways that you all know of to get my hp? Another reason I would like to stick with the 2.7 is because they have tweaked that engine so much that they have it down perfect. You always hear of the 2.7 tacoma's always outlasting the other vehicles. Very rarely do you see one blow up before it hits 300K. Any time you see the old ones, the beds are rusted through, and the truck if falling apart, but the engine is holding up as if its bran new. I definitely envy the hp that you all who own the v6 have.

 

Any time you get an increase of power, your fuel economy will go down. That's just how it is. You can find better balances to power/economy with some setups... but if you want more power, that means you want to push it harder, which means burning more fuel. There isn't a lot of room for minor power gains on these engines as they're tuned pretty well from the factory, so without forced induction (super charger/turbo) you're kinda suck... Sorry :/

 

Buy a 4.0L, problem solved

 

if my tacoma had 600 hp, a lot of us would stick our grubby hands in it to try n get 25 more hp. 4.0 is good , for my driving the 2.7 is good 'nuff and a bit more.

 

doug thorley headers will increase hp/torque enough. I would look into that if i were you.

 

I am looking at theses as well and I have a V6 W/only 7.5k
