3D model description

Supercharged rotary engine (single turbo) installed in the Mazda RX7, complete with turbocharger, injection system and exhaust manifold. High level of detail, the engine consists of several parts to be assembled including the oil pan.
Speed gearbox and functional internal parts (eccentric crankshaft, rotors and internal gears) will be available soon.
The gearbox is not included, it is available separately.

UPDATE:
- Exploded assembly drawings
- Correction of turbo files

3D printing settings

The photos represent the engine made with a resin printer, some photos are renderings of the project I made.
It is possible to print with FDM printer at moderate speed but obviously the level of detail will be lower and in some cases the supports will be necessary.
These are my printing parameters using Elegoo printers and YAJO standard resin.
