hey, im a bit of a noob with rotarys, so id just ask if it was a direct swap over to put a series 5 turbo motor and gearbox into a series 4 turbo car.

i just thought it would be easier to start with the higher powered motor instead of the series 4 version.

thanks for the help

 

You can give more boost to a series 4 than a series 5 because of compression ratios.But you could put a s5 into a s4 none the less with modifications.

Do a search and you'll find the answers!

 

just run a simple search and you will find everything you need.
