Uprated exhaust manifold

[Tsport DK]

Is there a uprated exhaust manifold for the yaris t sport mk1 1 nzfe engine? Ive seen some manifold for a scion xb which is the yaris in USA but i can see they dont have hole for the o2 sensor..

The Scion xB was based on the Toyota bB, which, although related to the Vitz/Yaris (built on the same platform), was a mini MPV, and was not the US version of the Yaris.

There are 2 versions of manifolds for the T-Sport/ 1nz engine. 

The pre-facelift models don't have a o2 sensor

The facelift model like yours does have a o2 sensor, the flange is also slightly different.

 

Quite a few people have welded o2 bungs onto them and adapt the flange which would be the cheapest route.

To answer your question yes the Scion XB/ XA mani's fit but keep the above in mind.

 

Another option would be to get a Yaris mani from the states as these already have the o2 bung 🙂

Yeah mines got an o2 sensor so i have to modify..

 

Ive heard the 2 nz manifold is bigger and is a straight swap🙂
