G'day,
I'm Javier, the proud owner of an old R21 in Argentina but currently living in Australia for a year. I'm not sure if I'm supposed to introduce myself elsewhere but I guess it's fine to at least mention this basic details here.
The idea of an engine swap for the R21 is something I had in mind for some time now. There's not much information about this (or at least I couldn't find it easily) but some of the folks here seem to have done swaps on other Renaults and have detailed info. This car came with a J7R engine (2.2L, basically a carburetor version of the J7T) and a NG9 gearbox, longitudinally arranged (north-south). I intend to keep the gearbox if possible, since that means I don't have to mess with driveshafts and the like, and it should handle the amount of power I'm planning with no problems. What I'd like to put on is a more modern engine, reliable for a daily driver. My first thoughts were the K4M (roughly the same power as the J7R, probably a little bit cheaper to run, plenty of parts/knowledge in Argentina) or the F4R (more power, still common enough) but I'm open to any kind of reasonable engine, even non-Renaults (I've seen people attaching many different engines to the NG3 gearbox in Lotus forums).
Does anyone know what engines could I mate to the NG9 without much hassle? Having drawings or CAD designs of the bolt patterns would be awesome, but even a simple "use the bellhousing from this, engines X and Y share the bolt pattern" is very much appreciated. From what I read on a thread here the "C" engine (R12) and the K4M seem to share the bolt pattern, for instance, but I couldn't find anything regarding the NG gearbox.
Many thanks in advance,
Javier
