I'm Starting a new project with converting a Predator 212 with a temu supercharger and/or turbo charger into a GDI equivalent to a Detroit diesel. For those who don't know a Detroit Diesel uses a valve train similar to a 4 stroke but it uses a super chargers air pressure to scavenge the engine instead of a exhaust and intake stroke. making it a 2 stoke with mechanical linkage. yes i know its not built for it and it wont last long probably it will probably over heat and float valves but this is more of a proof of concept thing and much larger project. its not powering anything its just there to exist.
im going to be running a hydraulic pump with a pressure relief valve back into the linefor a high pressure direct injector and weld and modify the head to mount and seat a 1.5l ecotec injector mill some fins off for a knock sensor and run a speeduino ecu then all the after market head stuff (push rods, springs, rollers).
im running into is a i need a ridiculous Double lobed cam shaft that intake opens at bdc and closes at 35degrees past bdc and the exhaust to open 15 degrees before bdc and to close at 35 degrees past bdc. to allow the blow through to scavenge the exhaust and to pressurize the cylinder. basically making the lobes look like lemons. Does anyone know of a shop that reckless enough to help a brother out with his now 3 week adhd obsession that needs to get out of my head? ill even make a youtube channel say they sponsored me and ill even pay for the damn thing. or if there's a way to grind off the old ones and replace them let me know.
