Yes, I want to use it for production if I did a good job on the demonstrator (Prototype). It is an undersquare engine and loves to revv low, I'm looking for 5500 peak rpm. I'm thinking of remapping the ECU and leave the engine stock.I think that Aeromomentum makes a point of not saying 'Suzuki' at all. Is this for a one off, or do you hope to go into production? Will you want to use new engines if in production? It may be best to get your plane working well before approaching Toyota with a fait accompli.
The 1ZZ is a very good engine, but has a long stroke. To get good economy, you should keep revs lowish, probably no more that 4000. You can save sone weight by replacing the VVT sprocket with a plain one. An aircraft does not need VVT.
