As far as I know, there is no such thing as a "GA60". There is a GA61, and this came with either a 1GGEU, or a 1GEU (like mine).

Norbie,

Isn't that because they'd designated the MA71 shells to be the turbo versions, and the MA70 shells to be the NA versions?

Then they found the turbo was WAAAY more popular, so they started dumping the turbo engines in the MA70 shells?

That would be a Gen1 or Gen2 version of the twin-turbo 2l six based on the 1G block.
Gen3 would be just 1GGTE.

Gen1 puts out 185hp, and Gen 2&3 make 210hp.

Considering you probably read it from that list above, the engine they are talking about looks like this: http://users.tpg.com.au/users/loats/technical/ra40/images/1ggeconversion/1G-GTE01small.jpg
