Hola Duck,
Me temo que te quedaste corto en el costo de overhaul:
FUENTE: Alexander Mladenov, 'Europe's Fading Fulcrums', Air Forces Monthly #330 (septiembre 2015), pp.47/49
FUENTE: Jane's Defence Weekly, 'Low serviceability leads to Bulgarian pilots refusing to fly MiG-29s', 25/10/2017
Adicionalmente, tomando en cuenta esos precios de motores nuevos y usados, uno se puede dar una idea de en qué condiciones estarán los motores húngaros (cuya flota de MiG29 dejó de volar en 2010) para que rematen el paquete completo (aviones + motores + armamento) a solamente USD 18 millones.
PD: sí, los nuestros son Serie 2.
Saludos

The time between overhaul (TBO) of the Klimov RD-33 Series 2 afterburning turbofan, delivered with the aircraft in the 1980s and the early 1990s, is only 350 hours. There are options for rolling extensions – initially to 400, then 450 and subsequently even 500 hours – provided the highest-loaded turbine components, including the blades, are in a good condition.The engine’s service life is only 1,200 hours, with two overhauls required; each overhaul is a costly, complex and protracted undertaking.
In 2014, the cost of overhauling an RD-33 Series 2 in Russia was around US$1.5 million per unit and the turnaround time not less than eight months. Second hand RD-33 Series 2s, purchased by Poland from Russian intermediary companies, with 350 hours TBO and 700 hours of residual service life, were priced at US$3 million each, while brand-new engines with longer TBO and service lives cost US$4 million each.

Overhaul work on the RD-33 Series 2 engine is undertaken at WZL-4 in Warsaw, but this is dependent on the supply of engine overhaul kits from Russia and the TBO of the overhauled engines is reported to have been set at 350 hours. According to the Polish press (the Dziennik Zbrojny.pl website), RD-33 overhaul at WZL-4 cost around €840,000 (US$950,000) in early 2010.

Under a November 2016 agreement with Russia, Bulgaria procured four new and six second-hand MiG-29 engines worth BGN42.7 million (EUR25.7 million).
