The GTI Crank has a shorter throw, not a lot tho, but you will have reduced
compression ratio, perfect for a turbo motor, but not a huge torquer it's all
HP and RPM so offroad ability could suffer if geared wrong

The GTi crank has a shorter throw than what?
As I indicated earlier, Suzuki offered two 1.3 motors in the Samurai - a 1298cc & a 1324cc - the principle difference between these motors is the stroke - the 1324cc has a longer stroke than the 1298cc.
If you're discussing a 1298cc Samurai engine, there is no difference in stroke between the crank and one from a GTi. The cranks are
dimensionally identical, the differences are in the construction - the crank from the 8v engine is cast, hollow and lighter, the crank from the 16v (GTi) is forged and has more counterweights.
I have one each of these cranks lying side by side on a bench in the shop, I'll get a picture over the weekend and post it.
