Cosmo Twins vs. US Spec Twins

My turbos are shot and can't necessarily afford a rebuild but have found a few sets of good Cosmo turbos for cheap.

What are the differences? output? bolt right up?

Let me know asap if you know ANYTHING.

Jeremy

I'm in your shoes right now too!!

BTW check out my thread

Will I'm going for the 99 spec. because it's different from the cosmo. the cosmo are just like our U.S. spec. turbos just that it is from a JDM vehicle.

nice, well I was assuming they were very similar to the US spec, but in the pics I've seen the plumbing looks a little different?

anyone know if the cosmo 13b secondaries are larger than the 20b secondaries, or if they just use the same turbos for both?
