Will the smallest turbine of the 20b COSMO turbo FIT on my FD?

I have a bad turbine on my FD, and my mechanich has 2 turbos of the 20b COSMO engine.

I looked at them, and there is one of the them that is exactly the same compared to my 2 FD turbos.... ( the other one is totaly diferent)


WILL IT fit ok?


I think that the stock ones are HITACHI 12´s.....


Thanx 4 your help again!!!

And excuse me for asking 2 much, but in Argentina is very difficult 2 find good help for my FD!

I *THINK* the cartridges are the same on the larger turbo, but I'm not 100% sure. You'd have to tear both turbos down to know.

But, used FD turbos are typically only $150-300 used depending on condition, and are easy to find. I'm sure someone can ship a set to Argentina .

The primary on the 20B turbos is a Hitachi HT-15, the secondary is a Hitachi HT-12, same as with the 13B-REW. I don't know if the whole snail will just transfer over though.

CAN IT BE POSSIBLE?????
