Question from a New buyer - Toyota Yaris Forums

CASTREX · 11-08-2006, 04:59 PM

Hi guys, nice forum you have. I'm from Costa Rica (central america... if any one doesn't know) and I'm about to buy a Yaris 5 speed manual sedan in a few weeks. I actually liked the LB better than the sedan, but in my country, the LB is only offered only with the 1.3L engine, so i will have to settle for with the sedan.

Any way, my question is regarding thhe HP and torque gains that I can expect from the basic mods that every body is performing into their cars:

AEM CAI
Exhaust (Tanabe??)
Headers (Megan...?)

I've red some data about the AEM CAI, claming 5hp gains... but i wonder what would be the overall gains of the CAI+Exhaust+headers

I'm not looking for a racing machine, but the Stock Yaris is a little underpower for me and i want to see if that can be improved it with little $$$

Thanks for all your comments!

First things first... welcome! Yet another country I haven't seen represented on the boards as of yet. So lemme be the first to say it...

Costa Rica = IN DA HOUSE

Anyway, about your question... nobody knows dude. Or if they do, they haven't told us, because I've never seen anything on this board regarding real world horsepower gains with ANY aftermarket part, and I check it... uh... too much. Hehe.

A spot of good news... shortly after the group buy for the Megan Racing headers closes, we will have dyno numbers for that part only, but don't expect anything crazy. With a CAI, headers, and an exhaust, I think 10 HP is totally reasonable, but that is a total shot in the dark. I'm hoping for 15+, I'm expecting 10 or less. Remember though, at 2200 lbs and with 108 HP out of the box, you'll feel a measley 10 HP in this car. We're just going to have to claw for every little foot pound and every little horsie.

I think that the bolt-ons make it a decent drive... don't expect the world.. but it should pep up the car just enough,....

I would have to say the only way to really test each part,is to test each part with the car completly stock,then remove that bolt-on and put in original,then test another part.I think someone should do this,just not me.;)

Thanks, for your reply and the welcome!

It's too bad we don't have real numbers...

Somebody really should take it's ride to the dyno... so the rest of us could have a better idea of what are we getting for our $$$.
