1.5,

I definitely agree about a few horses make a huge difference. In our case, you can't look at raw numbers. Percentages work great though. I have heard that a stick shift yaris has about 90hp at the wheels. If I can get myself to 105, that is an increase of ~16.5%. That is significant regardless of any other factor. The weight is a huge advantage too. I can't really lighten my load any as I use all the seats (on occasion).

A good friend of mine (the one that helped with the exhuast) pointed out that I am at the point where I need to either be happy with the small bolt-ons or go big. I don't think I will be happy putting that kind of money into the fic and only seeing minimal gains.

I am intrigued by the intake manifold but am having a hard time justifying that type of money for something that I am not 100% sure about (power wise). I have heard to expect around $500 for it. There again, that may change up or down some. I also would love to see a dyno graph of swapping the manifold and to a 1ZZ throttle body.

The other option is shifting the mechanical advantage more in your favor, so you can make better use of the power you have... Lightened flywheel, LSD and an xB final drive swap will gain you more acceleration than all of the engine bolt-ons.

You can cut quite a bit of weight if you know where to look. There is roughly 50-60 lbs to be had in the front seats another 15-25 in the battery depending on how you do that, another 25 in the exhaust and another 5-50 in the wheels and tires. If you maxed all of that out you're base weight is already down 150 lbs which is pretty substantial.


Its about managing expectations...I'd be willing to bet a full long tube header with 1.38 tubing roughly 60" long would make some large gains in the upper rpm range. But it all depends on what's worth it to you.
