I think pwede ata mga Mitsu engines i-swap into a Lantra. In one of Club Mitsu's previous EB's may dumating na naka Lantra and some of the members were saying the engine looks very familiar to Mitsu engines.

Also, I talked to George Apacible of MP Turbo and he said something like the Lantra's engines were in fact a 4G** of a Mitsubshi. If so, pwede ka magpalit ng engine. Not sure lang which batch of engines are applicable for the Lantra.

Pre 1997 model year cars that can be engine-swapped with for Mitsu's include the 2nd gen 4G63t, 4G93t and 1st gen 4G92 MIVEC.
