Economic RWD engine swap

Replacing the NB engine with something of similar power and displacement isn't going to buy you anything significant in terms of fuel economy, assuming that you don't want anything new and complex (e.g. direct injection). Definitely not a good justification for the time and expense required to fit a completely different engine.

Pretty much this.....

Throw in another NB engine & clutch, drive the tits off it for the next three months, then boost it over the winter ready for next summer....
