Breathe Yaris BREATHE! 1ZZ Throttle body and HKS exhaust

[@Big_E_Cheese]

The new exhaust and cold air intake sounds soooo nice tbh haba

[@OnlyforHobbyist]

This is interesting. I never thought that 1zz Throttle body would be so pnp with 1nz. In my country, people used to change the 1nz throttle body with 1TR throttle body. But it is so much for me because i have to made change with the gasket and sitting bracket for the throttle body.. Oh.. and here's one tip for you for the exhaust. I'm just sharing my experience, because we have the same cars. Try to change the header with aftermarket and change the resonator which have hurricane pattern inside, but keep the muffler standard. It will give you better throttle response.

[@kruiseorbruise]

What kind of headers and resonator do you use?

[@arvin_arn]

New exhaust sounds sweet! The 1ZZ throttle body is the next upgrade for me after I get my new brake parts

1ZZ TB does make for better response. I also oversized the plenum intake hole and got a 2'' MAF housing. Also have an straight thru exhaust with cat delete. Can't really notice a power difference. Mayybe better torque at low rpm. But mostly more noise fun! Be care full broring that plenum, it will mess up the channellings and make air go where it shouldn't. Had to use plastic weld to fix my screwup.

I’m sure this won’t matter now, but maybe try a different mounting position for the sway bar to make it act softer, and maybe use softer bushings on the links? That way it’s still active, but won’t make the rear too stiff?

[@North49191]

changing to a larger tb won't increase the amount of air going into the engine. The hole on the intake manifold is still the same size.

[@TheWilferch]

I think this is correct. The car's computer will still set the A/F ratio to be the same at whatever load and engine speed you are running. Maybe a chip change is such things are possible....need to be added to the mix. Another thing.....according to Bernouli's equation.....a smaller diameter pipe will increase the intake air SPEED, ( not the mass flow amount), so throttle RESPONSE may be worse with a larger TB. There are othr variables that play into all this....would love to hear your TRUE analysis of what this all did....instrumented before and after numbers would be the best indicator.

In theory. It is different for each vehicle and depends on how the ECU responds. On the Yaris it gives better performance at wide open throttle, but creates some issues at partial throttle.

Checked after 1000 miles so far, absolutely no noticable loss in oil, going to check every 500 miles until next oil change. So not sure if this is inherent with this motor or not but from around 2700-3200 rpms, it buzz's/vibrates, and gives the impression it's under very heavy load, and going uphill definitely noticable. After 3200 and before 2700, nothing really noticable. No knock, do hear a metallic clicking like rattle under acceleration, but very likely is a heat shield. Hard to get a good audio recording of it due to frequency, but millions of these cars exist and there's no way I'm the only one who has experienced this.
