Default Who makes a good quality 30 size and 40 size diesel engine?

I'm looking for both a 30 size (5.0cc / 0.3 cubic inch) and a 40 size (6.7cc / 0.4 cubic inch) diesel 2-stroke engine. Who still makes (or at least recently made) good quality diesel 2-stroke engines of these sizes? I'd like to aim for as close to exactly 30 size and 40 size as possible, i.e., no 35 size. Thanks!

Read through this thread, a lot of possibilities, the LA .40 and .46 are excellent conversions in this Forum: Page 3 Diesel 50's mostly.

Diesel .50s (mostly)

OS LA .46 Diesel conversion.

Currently, there is only one manufacturer offering full range of diesel engines, that is Progress Aero Works with Tony Eifflaender. They have 29 and 40 sizes. If select 29 I recommend TBR version. I'm using their engines for a long time without any problems. The largest in my fleet is PAW 35. Otherwise you can search through eBay or similar sites for Enya 30 or Irvine 40 diesels. Enya brothers now produce their engines intermittently and Irvine's are discontinued. However, with any luck you still can find their diesels unused or in good condition. Good luck
