Just bought 2008 Yaris,performance questions - Toyota Yaris Forums

toyotayaris08 · 01-09-2014, 10:32 PM

Looking into some performance parts for yaris. already eyeing some rims (14 inch might go up to 16) just wondering if anyone has recommendation on tire size for best traction. Although not an issue right now hopefully it will be in the future. Also if anyone could give me a rough estimate on how much the rotrex turbo's go for found the website but can not navigate due to it not having much English. also if anyone ran into any issues after installing the turbo. Thanks guys and girls.

Traction is a funny one and there are many things you can do to help this out. Realize that everything costs money. If you really wanted to go nuts with the traction, you can get an LSD for the trans along with meatier tires. I would also recomend stiffer springs.

The turbo seems to have so much more to do with the tune than anything (at least from what I have seen). Also, do some research and know what you are getting into. It seems that there is a hard limit of 9-10psi on these motors without going internal. The connecting rods seem to be the weak link.

That being said, there are quite a few turbo guys running 8psi and seeing ~175-180hp at the tires. There are a few others that have went internal and are running much more boost (highest I have heard was 32psi) and making crazy numbers.

Many guys on here run the zage turbo and I am not sure how that lines up with the rotex but there is a guy that sells them that is a supporting vendor of this site. He has all sorts of other things for the yaris as well. I stick with NA myself but there is a huge boosted community here. hopefully you will find all this helpful.

the guy's name is Garm and he goes by the screen name (Caliyaris). His website is (www.microimageonline.com). I have spent way too much money over there (most of us have)

awesome thanks for all the info, also no rpm gauge? Is it terribly difficult to add one. I was thinking of taking the hidden compartment in front of the steering wheel cutting out molding with fiberglass and trying to run it there. if its not a total pain in the dick.

Have a look through this thread. Then come back with questions.
