I just thought of something else that makes the Soliad 4.4 a better choice for a Covet swap: it's transversely mounted in the Wendover, so it can fit more easily in the back of the Covet. Plus, it's smaller and lighter than the Gavril 6.9 and, being an OHC unit, it can make equally giant amounts of power and torque to the Gavril 6.9 when given the right parts. So yes, your choice of engine makes more sense for street and track performance. Yep, drag use makes more sense with the Gavril 6.9! Hehe! Also, yeah, I hope for a V6 AWD powertrain too because there's the niche of the Mid-Engined AWD Group B car needed to be filled! Also, a small Diesel engine makes great sense for a Supemini - passenger Diesels started being popular in the early 80s, so the production years of the Covet are right on. Plus, the niche of the old passenger Diesel has a lot of unexplored territory in the game (ETK, Ibishu, Bruckell and even Autobello - provided it gets a car made in the 80s or newer - can have many of these, with Bruckell starting from the late 70s)!
