Performance Mods
Okay so I have a 2014 Yaris (03/14) 4dr, and it's a nippy little thing!
I was just wondering what type of performance mods all you guys have done on this generation of Yaris? I live in California, so I am limited as to what I can LEGALLY do on the engine and such, however I am thinking about doing the suspension, low profile tyres and nicer rims (I know those two are cosmetic rather than performance) I'm thinking about doing a RAM intake too, but I will have to remove it and put the box back in every 2 years, so we shall see!

suspension and tires are the most important part of performance. do that first.
remove and install airbox=15 minutes 1zz throttle body is great. $35 at pull&save or whatever... i have a ported manifold with spacer for sale http://www.yarisworld.com/forums/showthread.php?t=58478 |

Performance Mods
Quote:
You can swap the 1NZ for the 2ZR from a Scion xD or Corolla. That adds 30 easy horsepower and no considerable weight gains. Transmission bolts up the same because those cars use the same (automatic) transmission, albeit with a different flex plate. It's fairly easy as far as motor swaps go but not all that cheap and it's also quite difficult to source a good engine for decent price. I was going to just get a salvage donor car from a local yard. Motor mounts up pretty easy but getting the ECU properly wired up is tricky, you would also need a custom fabricated exhaust. It's totally smog legal too as long as the motor is from a 2014 model year or newer vehicle. (I live in cali too, I've done my research, I just haven't started yet because I'm still preparing my budget.) For cheap stuff, get good wheels and tires and a rear sway bar. That will tighten up the car really well. Perhaps even some chassis bracing. Steel brake lines would be a good addition as well. Can't go wrong with good CAI and exhaust too, combined with a 1ZZ throttle body. I've heard of people using 1ZZ injectors too. Those would be smog legal too if you hide them well enough with a CARB legal CAI. Sent from my iPhone using Tapatalk |

you would only install 1zz injectors if you are running forced induction or E85. if you install them without a need, you will run rich and do damage to catalytic converters and sensors. no gains to be had from injectors alone...

Gotcha. To be fair, I said I HEARD of that. I didn't do much research on injectors. Sent from my iPhone using Tapatalk |

It would be nice to get a better exhaust and such. CAI is going to be the first port of call. And I have been looking at throttle bodies, but couldn't find any. (I'd have to get one off of a corolla or something - you say?) Tires I'm going to get some decent ones, and some nice alloy rims too, as the steels look kinda pants. The suspension I am looking into, but I don't want it too stiff because the Cali highways SUCK. Thank you for all replies though!

Another fairly straight forward mod is to replace the crank pulley wheel with a low-weight pulley or an underdrive pulley

If doing that, try to get a pulley in either a black or grey colour, so if doesn't stand out...

You can have an exhaust in Cali as long as it still has a cat and muffler (cat for smog and muffler for noise limitations. As long as the muffler isn't STUPID loud, you'll be fine) However, most people save their OEM parts and for smog then they run the aftermarket parts afterwards. I would recommend registering your car in a class 1 smog area (small rural towns) because you only need to smog your car when you sell it, otherwise you never have to smog it in Cali A 1ZZ throttle body is a pretty straight forward swap, those are easy(ish) to find for cheap. You can look for them on eBay or junkyards, etc. corollas and celicas with the 1ZZ motor And yes Cali highways are garbage. I feel you there. Sent from my iPhone using Tapatalk |
