Modification
 

Hi,

I heard for every rotary car, you can't simply mods your car like other cars for example: sti, evo, skyline.

You have to make sure your car is running normal not lean, is it true?

So if i just wants to mods my car like air filter and full exhaust only, should i get ecu to adjust the air fuel ratio?

This question is regarding a series 8 rx7
