hey, a guy that sells these injectors said they will fit into the secondary fuel rail of my series6,

i asked him if they will fit and he replied with ....
"I will just supply some 11mm o-rings for you to place on top of the injectors. The bottom o-ring completley covers the hole in the manifold and the downward pressure of the rail holds it all in tight"

what do u guys think,,,,,
and would 550/1600cc be an acceptable combo?

 

The stock secondary fuel rail is made for side feed injectors. Those are top feed!
Go look at what the RX-7 Store sells!

 

It's not legit. There are no 1600cc injectors that fit into the stock fuel rail. Look out for a company called Venom, they are not legit.

 

its an online store here in Australia, the guy said he would refound them if they didnt fit.. im bit cautious now from what u guys have said
