Yaris T1 (1kr-fe) (998cc) aviation conversion

[karman]

Hi All,

Hope someone can help me on this.

I'm converting the above motor for aviation use and need about 15hp more out of the stock motor at 6000rpm (climb/takeoff). Cruise is at ~5400 rpm. The rest of the RPM range don't get used (except for idling of course which can be anything from 1000-2500rpm ).

So, I was wondering what will the easiest mods be.
Noise is not issue.
Fuel usage not issue.
low -> mid range power not issue.


I have to change the throttle body from the "drive by wire" system to standard cable and so I can fit larger bore if that will help.
(Also don't need TPS sensor as throttle will always be advanced/retarded slowly)

Regarding the VVT-I. My understanding it only assist in mid rpm boost, don't do much or high rpm, is this correct? Otherwise I can simple activate it fully at X rpm and make it VVT (without I) as the older motors was.

Any input appreciated.
