@@cyrillegreasley7254 Hey there! Happy to hear that you have been enjoying the videos! I'll have more to come soon! To answer your questions: #1 I'd recommend doing the injectors without them you run the risk of your car running lean because you are adding more Air. Anytime you add more air you should ideally add more fuel so that your air fuel ratio will stay the same. Too lean (too much air) and you'll burn valves too rich (too much fuel) you'll wash the cylinder walls out neither of which are good. Its all about finding a happy balance; so far so good with my set-up however yours may differ. Be sure to do new o-rings if you decide to upgrade your injectors. #2 the intake spacer I have is a Tooter spacer. Unfortunately they are not made anymore so you'll have to try and find a used one. I just got lucky and found mine on Facebook marketplace. I'd recommend checking out the Yarisworld forum and see if anyone has one they'd be willing to sell. This is not a necessary mod. #3 Most likely FTG is in the middle of their racing season. I'd recommend continuing to email them and possibly look for a response a little later in the year when their racing season has cooled down. Feel free to reach out anytime with questions, I'm happy to answer them! Good luck with your project!

@@TheInteriorAutoMechanic Thanks for the quick response! I'll have to try again with FTG tuning. Thanks for answering my questions I'm sure I'll have more in the future

@@cyrillegreasley7254 happy to help!

Hi there! I am in the process of doing more filming currently most of which is done I just need to edit it all together. I am hoping to have a few more videos out in the following weeks. Please consider subscribing so you can see the videos when they come out!

Thanks for reading. I’m subscribing. Like to see more videos thanks

@@ericm1211 No problem at all thanks for subscribing!

I haven't driven it just yet. Currently I'm waiting on shifter cable bushings to arrive. I'll be installing them along with some other transmission parts and filming all of that next. Once that is done I'll take it out for a drive and see how it does, I'll be sure to make a video on that as well. Thanks for the kind words I appreciate it! Please be sure to like the video and subscribe to the channel!

Looking forward to it! Already subscribed!

@@TheInteriorAutoMechanic sounds good. I would also be interested to see what your mpg is like with your mods too. Looking forward to an update!

Hi there! I'm still in the process of getting everything put together on the car and getting it ready for track days (more videos to come soon). So far though whenever I've fired it up in the garage it idles great and no check engine lights (so far). Be sure to subscribe so you know when the next batch of videos in the series comes out!

@@TheInteriorAutoMechanic Got you! Fingers crossed thing are ok on the road too. I did subscribe :) Thank you!

@@aleksandrk9452 thank you!

You would not want to just do an injector swap if everything else is stock and unmodified. The reason we did the injector swap is because we were adding more air by having the ported intake manifold, larger throttle body, and cold air intake. If you were to upgrade you injectors with no other mods, your car will be running rich and your fuel economy will go down. Plus most likely you'll just lose horsepower because of the richer air fuel ratio. It will not be burning efficiently and giving you optimal power.

Awesome 😎 stuff, thanks for the knowledge, planing to beef up my 1nz , watched your video and kinda got curious how much HP I can achieve with the exact mods you did ,mind sharing thanks!

@@user-zf5hh7wm3kno problem at all! I haven't taken it to the Dyno yet. If I had to guess I would say I've gained somewhere around 30ish horsepower over stock with everything I've done. It may not sound like a ton but it has definitely made the car more fun to drive. Please consider liking the videos and subscribing to the channel.

@@TheInteriorAutoMechanic thank you so much for information,I will follow you

Hey picked up a Yaris too. What exactly did you do? For that 30hp butt dyno.
