If the top cars doesn't even get crazy mods, it's unlikely you will find much of anything.

You best bet if you are really truely a diehard fan, import a Yaris TS with 1.8 Dual VVTi.

Its really not a big deal,when I bought the car I knew there was a good chance the aftermarket would never become much. I bought it for mpg mostly. Still a fun car,I'm gonna auto X the piss out of it.

considering that the old 1.6litres 4afe and 1.5 3e/5efe were producing less than a 95hp at the crankshaft....i think the 1nzfe is quite good....

if you take the Aveo its 1.6l engine produce 103hp and 107lbs

3hp less an 1lbs more than a 1.5 toyota...


an egine that is coparble to the 1nzfe is the honda fit

1.5 109hp 105lbs


so the 1nzfe is not that bad

This is exactly why this motor was not built for high revs or super performance. 99% of the people who buy these cars want MPG and long term reliability. Those of us here on these forums who are after more power are a very small sector of the overall Yaris community.

I don't really see any big power upgrades in the future for the n/a.

and also 90% of driver does not like high rev engines...

this car with 140whp would be plenty quick for the weight and could centainly be had with mild fabrication and a decent machinist... don't need big power in a vehicle like this. just need traction and a diet
