USDM 550cc Injectors with 7m fuel rail

[Fubar231]

Will they fit? Also, will i need new pigtails and have to wire them in? I believe the USDM 550cc injectors are low impedence. Could anyone shed some light on this before i drop some money on some.

AFAIK MK3 supras never came with 550cc injectors.
Also, I don't know of 'drop in' injectors for the 7M. All injectors need some kind of modification to make them fit the stock clips. (or you can replace the clips)

Top feed injectors WILL fit your fuel rail however.

550cc Nippondenso injectors will most likely be Mazda RX-7 Injectors. Be sure to get the right type.

If you are talking about MK4 injectors, you may want to have a look at a picture of them before considering this any further.

top feed and side feed are NOT interchangable.

Suprasport makes drop in 550cc injectors without having to change the stock clips or cut the harness. Heres the link: http://www.suprasport.com/SupraSport-Custom-Injectors_p_5466.html

HKS also made direct drop ins back in the day. They are super spendy to buy used now but I have seen a set in person. Yes, I do feel special.
