Hello I bought my Z 2 years ago, and now I think its time to do some upgrades but

I live in Brazil, the monthly wage here is like 150-200 usd ( Not for me but for most people )
Dollar used to be 2x1 against our currency, in the last years it became 6x1 ( 6 our currency = 1 dollar )
There are no used transmissions or even new ones to sell of Z's
Importing things we pay 100% fee over the shipping + product price ( so if I pay 2k in a cd009 or something I will pay 2k + shipping fee x2 )

Some people told me to use the MT of Frontier 4X2, any other ideas for a swap without importing? Any other cars that we could adapt the Trasmission or any other that will fit with minimals adaption?

The plan is go to a turbo at all
