What size injectors are in my 13b-re?

Got to thinking, wonder what size they are today. I know the FD's have 550 primary and 850 secondary but what are mine?? The FD has 255hp while the cosmo had 230hp, think they would go to a smaller injector?

Also do the FD injectors look like these in the pic, my primarys look to be side fed injectors.

One more question, What is that sensor or switch for on the left side of the primary rail?? Thinking it must be some sort of pressure switch or a temperature sensor.

it's suppoed to be 550cc all the way around. the other sensor is the fuel thermosensor they use it for better hot starting

Primaries are 550cc (I am still using them in mine) and the secondaries are 850cc. I have replaced these with 1650cc Bosch injectors. Cosmo engines have side feed injectors. Much painful to replace the injectors because of this

The green plug I think is for temperature, not 100% because mine has always had a custom fuel rail.

FD have 850cc injectors secondary? I thought all turbo 13B's (in the US anyway) had 550cc injectors all 'round. Live 'n' learn!

Do you have new rails for both the primary and secondary? I'm assuming they are custom made??

Only the secondary rail is custom. I still have the factory 550cc ones down the bottom for that baby smooth idle
