engine die cast ?

Williams Bros makes a few large scale aircooled aircraft engines.  The company was sold awhile ago, and I believe the only ones re-released are the Le Rhone WW1 rotary and the Pratt and Whitney Wasp Junior.  While Wiliams bros kits vary in quality, their engines are among their best kits.

There are a couple of aftermarket suppliers that make auto engines in 1:25 scale. I think Ross Gibson is one of the brand names. Best place to ask about those is the Autos forum.

There was a kit, long out of production, of an Allison  turboprop engine by a major mfg, I think maybe Revell but not sure.

i will look them up, i have a 3D printer i might make a few of them :)

Yeah Ross Gibson makes killer resin engines, and a ton of different ones.  You pay for it big time though.  When an engine is as much or more than the kit.... I tend to have an issue forking out any money for that.

looks like all he does is car engines but what about rocket engines or jets, for example i found these.

Roden does several aircraft engines- three WW1 era ones in 1:32, and I believe maybe a Daimler, forget which model.
