100k budget not 10 and I mentioned that I need to look into the STC’s. Starting with a 40-45k G leaves a lot of room to play, excluding work to the panel, but that goes a long ways for motor, paint, interior and speed mods. Most motors in question can be bought in the 45k range. The plane I’m looking into already has a new 3 blade hartzell prop, I found an SCT to put a 200hp lycoming in the G which would get around 155-160kts which would be OK but wouldn’t really fit in with my mission (to destroy a bonanza at 100k) it’s a little slow, but I’ve read that there’s an STC to turn an F into a missile which trues at 180kts. That’s why this I started out asking about all the different conversions G,F,J,K, there’s got to be something kicking around after 5 decades for the G. If not I’m not opposed to taking it experimental there’s a lot more freedom going that route.
