I want to know if I should replace my primary injectors fuel rail for a bigger one. Some people tell me to do it and some not. The car is a street driven 1990 TII, road racing once or twice a week. Street ported engine, T-66 turbo, microtech LT-8s, 1600cc secondaries plus a bigger fuel rail (secondaries) by rx-7 specialities, Cosmo fuel pump, fuel pressure regulator, ... 10-12 psi ....

I would also like to know if I should upgrade to 720cc primaries, or keep my 550cc ...

thanks for your help !!!!!

 

Why upgrade? Do you want to turn up the boost? Find out if you need them here:

Road racing = driving on a track with turns in both directions
Street racing = racing people on public roads

You really get to road race once or twice a week (lucky!)? Or do you mean street racing?

Anyone even know where to get a primary rail for an FC? Will you be getting one custom made?
