200 hp without a Supercharger

I know that everyone knows how under powered the 4 cylinder tacoma is. I'm ok with it for the most part but when i'm driving in hilly areas it becomes a task to keep up with traffic. I can't help but think that a 2.7 liter engine should be capable of well over 159 hp. Hell my Mazda 3 that i had before this made 160 with 2.0l.

I guess my question is, is there a way to significantly increase power without with out a going forced induction? Of course the regular thing such a intake and manifold as well as exhaust and the manifold that goes with that. But what about rocker arms and spring replacement? injectors and a remapping?

My knowledge of this engine isn't that extensive yet so i ask you. Any information would be great. Thanks

 

I had a pretty intensive thread going on getting a V6 up to over 300 without going forced induction. I would guess getting 40 HP is going to be pretty tough. Headers exhaust intake filter. Those are good to get some.

 

trade it in for a 4L with the supercharger...if you're concerned about power and bought the 2.7, you got the wrong truck...just saying

 

^ THIS

 

200 crank hp MIGHT be achievable with intake, header, exhaust, and URD MAF sensor calibrator. If not you may get close lol

 

A few things to consider:

Less weight is the same as more power as far as getting up to speed and climbing hills. If you have a standard cab then you have helped the cause, 2WD saves hundreds of pounds also. But once you buy the truck about all you can do is make sure you are not hauling around any unneeded weight. Say NO to heavy tires.

For more performance consider swaping the 4.10 gears for 4.56 gears in you differetial(s). This won't hurt gas mileage much but will liven up the performance.

 

oh PS if I wasnt building my truck to race I would throw a small block in or a blower in it and not waste my time with the 4.0L

 

What if you just put a V6 in it

 

I'm about to sleep so short answer now, explain more later. Quit thinking in terms of numbers, what you need is mods that also increase the powerband into your lower RPMs. 200hp means fuck all if it takes till 5500 rpms till you can use it. Hence why some headers show miniscule "hp" gains even though they move your powerband 4-500 rpms lowers.

Easy stuff:
- Premium fuel
- all synthetic drivetrain fluids
- lightweight pullies
- Performance plugs
- intakes & exhausts meant to bring power band lower, not just increase up top.
- tune.

You could easily hit 200 hp with about 1700-2000$ spent at the right places. and increase your mpg's quite a bit too. My Xrunner was getting 23-25mpgs.

 

I got the 2.7 because the v6's that they had were all 30k and up. I'm not worried about power but it is something i was thinking about. Im in no rush but if there are things i can do over time to increase the power then i'm all for it. just saying lol

 

All the power to ya, pun intended. Which upgrades do you plan to do first?

 

haha, I wish. I really wouldn't mind doing that but not until later when i would have to money

 

What about Cam gears for the 4 cyl? I bet that and maybe some cylinder boring after that lol i have no idea

^^^ nice morpheous lol

 

Cam gears dont make power, cams do. Gears are just for degree adjustments.

1) You're not going to make 200whp on stock ecu and a budget
2) If you dont have a budget you'll need this
a. Standalone ecu, ie: Haltech, AEM, Megasquirt
b. Nasty N/A headwork, w/ valve springs and retainers to rev it out
c. Cams
d. exhaust, headers back
e. fuel system upgrades, more than likely larger injectors since stock pump should feed it N/A
f. If none of the above works, Hi-comp pistons and might as well do rods while you're in there...

 

Werd.

Then slap on a turbo kit as well.
