Newbie with Q's, reliable WHP

[mickymouse]

Hi guys,

am reading already a couple of days in this Forum, so far I have not yet a complete picture of performance modifications on the Yaris.

Here is the deal, I am waiting on my new Yaris 1.6 RS manual transmission. I live in China, thus I am not sure if we share the same engine. It is (yet) the 1.6 l 16V engine, generating 118hp@6000RPM and 150Nm@4400RPM.

Here is what I want (engine):
a rev happy engine with an aggressive sound.
Since I drive my cars hard (after apropriate warm up) I definately want RELIABLE performance increase. I do not want to open the engine with the exception of changing the cams.
I would really like to have a 15% - 20% power increase vs. stock.
Stock would be about what... 90-93WHP? So something like 105-110WHP is my target.
No FI, only all motor.
I am willing to sacrifice some low end tourqe for high rev power. Similar to smooth power development up to 3500-4000RPM.. picking up at 4500RPM and reving quickly towards rev limiter or close to 6800RPM.

I am a "do it yourselfer". Modded a few cars in the past.
In this case I would like to purchase at one location a package deal, something that is known to work.
What I am willing to do is:
CAI, UDP, cams + cam gears, bigger MAF, header, complete exhaust, possibly modified ECU.

Here is what I want from the suspension point of view:
dropping the car without bottoming out (maybe 1 1/2 to 2 inches?????), adding spacers to the wheels so they will be flush with the fenders, nicer rims and maybe 185 tires.
So, a good coil over would do the trick that I can have a limited smooth ride on the straight.. and a nice cornering speed? I defiantely want handling and corerning spped, since the Yaris is not a high speed car, would like to have a nimble handling car. Thus, changing the sway bars is a must.


My question to you guys:
a) my expectations on the reliable engine power, is that reasonable?
b) my expectations on the amount of increas, is that reasonable?


any feedback is greatly appreciated, thanks a lot to you all

ho ho ho
happy christmas
