Anyone know of an easy way of squeezing 10+HP out of a stock manual xA? When I say stock I mean it hasn't been modified even by the performance parts Scion has. Also I'm not considering Turbo/SC's because I know what they can add.

Thx for any help possible

 

Lots of speed decals.

 

Free flow Intake, header, exhaust should net at least 10 to the wheels.

 

Umm... maybe I'n not understanding your question, but hp doesn't change much from from the factory spec on a car that is "stock".

<sarcasm>
Perhaps you should be willing to add/modify SOMETHING if you would like 10 more hp.

Of course, if you do find a way to make 10 more horses come out, without putting anything in it at all, be sure to let Einstein's heirs know that you've broken the theory of relativity.

chrome dipstick...

 

Intake , Header , Cat back exhaust.

if you want more buy

iridiums , weapon r engine damper , lightweight pulley

 

I have the Denso Irridium plugs............no horspower gain... I also am skeptical about the engine damper......no one has shown any dyno tests proving their worth

 

1. Injen Cold Air intake
2. Strup or DC Sports header
3. Greddy, Borla, Strup, InVidia Axle-Back.

You add little more the turn the axle back into a cat back at your local muffler shop and BAM!!! 10 horsepower. And as mentioned above if you want litrle more like maybe 7-8 add:

1. Perrin or Unorthodox Pulley
2. Any Iridium Spark Plug with decent spark plug wires
3. Weapon-R Engine Damper (wont give power but will help balance the power you do have)

 

HotBox05 - Nail - Head

Though I would skip the iridiums.

 

Pour sugar in the gas!!! :D

 

worst case irids waste 36.00 shipped.

 

well i have the damper and i can guarrantee it helps out alot

 

Sorry....but I am not buying until I see imperical evidence......kinda like buying a Tornado......until I see proven results I am gonna say it is heresay

 

What brand?....Not Denso's for that money

 

By far, hands down, the best bang for the buck is a pulley kit from NST, www.NonStopTuning.com

 

ngk IX's.

ebay is the BOMB. lol

 

lets put it this way. I can no longer keep traction if i push it. whereas before i only lost traction here and there. now if i push it hard enough i can spin sooo much longer. is thata a benefit? no. buit i'm also pushing this motor to it's limits and with stock tires. put some nice sticky tires and a GOOD clutch unlike stock . and man oh man. hook up like a ****.

 

hmmm.... would this damper help an auto??

 

Me to... I want to know if any of this stuff helps auto. Also, if the intake, pulley, exhaust headers, plugs, and all the other add ons can increase the power output why don't we ever see any proof of this with dyno comparison charts? I believe it's because the improvement gains are minimal. If we look historically at this displacement figure of 1.5 liters, and accomanying power output, it is obvious Toyota is getting good Horsepower out of this engine and minor mods just aren't going to make much of a difference. I'd love to see some links to contrary information and be proven wrong on this.

 

Which ones u have ???? I have IK20 ..... accelerations kind of improves......especially after the 3000rpm mark.
