Hey guys I am new on your site!! I will be getting a 1993 Rx-7 from Japan in 2 years and was trying to find some info out!! Just wondering if the Rx-7 came with the 20b twin turbo engine in it from stock do you have to swap that motor??? Also what is the horspower for a stock 13b twin turbo engine?? what would the horsepower be for the 20b engine??

Thanks

 

Start here in the Newbie/FAQ thread:

Look under the "Buying used" for the specs of a stock FD, and then look under the links for the 20B swap.
