Pff on turbo

[Yoda]

So if some remember about 2 or 3 months back i started my quest to turbo my car. Well its hard and not enough data out there on turboing a yaris especially for me to feel brave enough to start it. So i sold all the parts to some asian guy Now i am back to improving my N/A power.

Is there i mid-pipe out yet for the sedan? what other options are there N/A wise?

The Blitz kit is way too much in my book so don't even mention it

custom midpipe is your best, cheapest bet.

custom exhaust, header-back shouldn't cost you more than $300 or so. The intake manifold we're developing will hopefully make some power.

Does this price include mandrel bends?

but i love my trd exhaust

[cali yaris]

It did for me. Resonator in the middle, Magnaflow muffler, dual-tip center-exit.

i don't know a lot in this area, but I think if you want any noticeable gains in NA, what I've always been told is balance and blueprint, so new internals (higher strength and lighter connecting rods, better pistons and headgaskets to take a beating, all well-designed internals, a more aggressive camshaft valve timing) ultimately up the compression and possibly maximum rpm's, and tune it with a new exhaust system.
I think throwing in a exhaust system to a system that is already tuned well enough by toyota is a bit of a waste (*ducks and covers*) hope I don't hurt any feelings; 5-10 HP for hundreds of dollars is not my idea of a good money well spent, not to mention there is possibly additional weight with these new components. either way power increase will cost, but a well-tuned and ramped up NA engine will be a blast, and at similar weight with no additional parts to necessarily go wrong; I think you could ascertain maybe around 140HP with something like this, though it won't be cheap...I think that's why most jump on the turbo bandwagon...anyway..
someone on here was rebuilding their engine's internals, as I saw some connecting rods pictured; but I don't know where it led to.

i got quoted 300CAD for stainless, mandrel-bent, midpipe from behind my resonator to the axle to meet w/ my megan axleback....2" at that

n/a is a waste of money. spend money making the car turn better.

and stop faster/more consistently

the brakes on these cars fade like a mofo

suspension/brakes should always be a priority especially if your car is slow. you make up more "time" and spend less money doing it before power

[RacerFreakXXX]

+1 on that. Make sure you car will be able to handle the power before you add it. My friend has 260whp on a 05 civic si and has no diff, no suspension, just a front strut bar and tq damper. I told him to just spend the money and buy a rsx and do suspension and now he wishes he had done what I said. Also I might add, turbo kit or supercharger it's the same cost. I priced it out and to run on a stock engine the turbo kit just takes some time in the shop with a dyno and custom piping.

They sound a bit different don't they? Plus since a supercharger's boost is constant and a turbo generates it through exhaust I would assume a turbo's boost gauge would be more fun to watch.

Plus, there is that unbelievably sexy hiss sound that a turbo makes as it spools down (I think that's what's going on)

As far as my thoughts on power vs. suspenion: I went suspension first since I'm a budget modder so it looks like I'm good!

A couple points to hit

Eh wat n/a waste of money? Then half the members on this site wasted there money. It might not be the best setup for our small displacement engines but i dont think its a waist of money.

-1 on that. We drive a yaris and would be lucky to see +20whp with bolt ons . I should end it there but let me explain. Unless you are boosted up your stock suspension is enough to handle what ever bolt on you are going to put on. To gain all the benifits out of it suspension should be done imo. And i think most are taking it a little too far with all this talk about handling. Most here do not tack and will not be taking any 90 or 100 degree turns at an accelerated speed. And the cost is not the same. Much cheaper to turbo than S/C including piping. Dont add dyno to it cause you have to do the same if you S/C.

I have heard many say you need to do work on suspension before you do your bolt ons because {reason} and {reason}. We dont gain that much from bolts ons not enough to warrant struts, coilovers ect.

For those who dont kno or have forgotten my past posts i have already done suspension about a year ago before the hack even.
{end rant}

$1500 for 15hp is not very smart IMO.. and yes, anyone on this site who spent their hard earned money (guessing it's earned anyway) on n/a mods for the purpose of "more power" should have spent that money on better tires, suspension, or something altogether different.

or nitrous.

it's a 1.5L econo engine that's over-square, has an offset crank, and simply awful ECU, (designed for economy). all that money you'll spend and you'll get beat by your grandmother's corolla.

don't forget guys, i own the same engine, i'm not attacking the car. i'm just saying, spend your money on stuff that matters!

edit: i am aware that most car enthusiasts mod simply for the sake of modding. that's fine, just don't do ALL THAT for your yaris in the name of "more power"

You say that like it's a bad thing?

[fmicle]

I think some of the mods do make the car a little more fun to drive. I also do believe the same mods provide a modest increase in power, but do I really feel the difference of the extra 5 WHP I probably have now or is it all in my head?

I am not comparing my Yaris to other sports cars, but to other Yarii and that's where the mods make the difference. If you want power, get a diesel truck or something
