I have a 88 13b non turbo , is it possible to put the 18B twin turbo in it?

 

There is no 18b.

There is a 13b-REW twin turbo from a 93+ rx7 FD.

 

Put in a 20b

 

what he said^

 

if you do not know the name of the motor i highly doubt you can take on the task of swapping a 13b-rew motor... no offense but it is a big project

is there a kit to put the 20 b in a 88 13b

 

18B is ricer language for a Honda B18B

Dood those ricer magazines try to make you buy stuff. If you really made your car like that it would cost you like $100,000. Save yourself a lot of time and money and just buy a TurboII RX-7. The junk yard will give you like $50 for your car or you can use it for parts for your TurboII.
