RS Intake Manifold,airbox mod and 1zzfe throttle body/injectors

[Compeer]

Hey guys I have been planning on doing the 1zz-fe throttle body sway for a while and have been reading up.

Found these guys selling RS intakes saying they produced a little better top end power and torque, it's one of the mods they do in asia.

Here a pick showing the difference, it's funny becasuse there is the mod to increase the size again from the longer version, which they said lowers where you get the torque but will decrease hp and toyota does know what they are doing and the best NA cars have short stacks not long ones.


So I am picking up the intake and airbox today from an RS, Plan is to mod the airbox by removing the ribs, adding a performance panel filter and then enlarging the intake hole and adding an intake trumpet facing down into front bumper from the opposing side as the factory had it so the air is always flowing the same direction. May use some ofther factory car intake pipe to run from airbox to bumper cavity. I want to keep it short so not all the way down into bumper, with the floods I don't need my intake to low

For the intake manifoldI will use high temp plastic or even a wood adaptor plate with some gasket paper to fit a 59mm throttle body ether from a 1zzfe or a 1az as they are both the same size and we dont care about the electronics anyway as we will be following this amazing New Zealand guide https://sergei.nz/toyota-vitz-rs-and...ttle-response/ So will be replacing the insides with the current yari insides of the throttle body and adjusting idle screw.

The 1zz-fe injectors and Throttle body I still need to go to a PickaPart wreckers and take off a car. Injectors will then go and be cleaned and flow matched with new filters and o-rings. Its about $33nzd an injector at local shops here in Auckland city.

Picked up some of the parts yesterday.


Can see the RS Shorter intake and its part number.


Time to MOD! Starting with the Airbox!

Used various pliers and what not to get all the ribbing out I could.


Then started to get serious and cut off the old intake ring to be used on the opposing side as well drilled out a hole for the new intake.


Then I got out the soldering iron and went ham using the plastic pieces I had removed to plastic weld the intake on and to seal the old holebefore sanding it all.
