I am about to start to fit a 4 age engine in my car running twin webers. If anyone has any parts that could help with this conversion please let me know. Things I know I need:- Bellhousing, TPS mount, Trigger wheel and sensor Then a omex plus loom. Weber to 4age manifold

Hi Dave. Regarding the trigger wheel... if, like the 3SGE, the 4AGE runs the TOYOTA CAS ignition as I think it does it will have several sensors in its distributor. One of these is a 24 tooth wheel. I removed one tooth to give a 24-1 missing tooth configuration. As it runs at camshaft speed it can be used for full sequential fuel/ignition. My Megasquirt MS2 has four spark drivers to give sequential ignition via COP.
How many spark drivers does the Omex have?
You might be able to run without a TPS and sense load using a MAP sensor, as long as the Omex is happy with it. I have a Toyota MAP sensor if you wish to go that route.

Danst will make a manifold for you.

I think the Omex has 2 and uses a 36 tooth trigger wheel then a Zetec coil pack
