again, not very cheap.

really dont think its gonna cost $1000 for cams for this car. I cant imagine anyway it would. It most $800.

this guy has bought some new internals: http://yarisworld.com/forums/showthr...pistons&page=3
mostly I'd be interested in is those rods, they look substantial (though I think they lower the compression), I'd also be interested to see if anyone adapted the prius pistons (http://www.yarisworld.com/forums/sho...rius+internals) to a yaris, they possibly handle a greater compression ratio I believe or if anyone found some new head gaskets.
if you did increase compression, a new camshaft would most likely be required, or atleast adjust your current one to properly reflect this.
with all of this, you'd REALLY want to plan this out and make sure the components are highquality, stronger than original, lighter than original, and made to greater tolerances than original; then find a way to tune the whole thing (probably the most intensive and important portion of this whole thing)...to save money you'd want to probably do the install or find a friend to install the components.
as well, this would only really work on 2 main aspects of the engine (how much more energy it can extract from gas using a higher combustion point, and possibly how much faster your engine can cycle-- something I would not venture on personally as much more work needs to be done).

other than that, find a way to drop weight significantly while still catering to your lifestyle: http://www.yarisworld.com/forums/sho...ght+reductions
a drop in 100lbs (dead,non-rotating) weight would be about a +4hp equivalence...

I ignored all of the first of your post as its clear you didnt read mine where i stated that i would rather not get into the engine and opted for other means.

Look at my dyno again i need about 8whp to make it to 120. I kno this can be done without getting into the engine. Just asking for some more ideas.

So plz no more talk of how expensive it is to go N/A or these over the top engine builds. Keep its simple bolt ons. U have my post with my dyno and mods. Give me something i haven't thought about.

I like the weight reduction idea. Will have to see if i can manage that.
