Default Supra 550cc injectors, anyone use them?

My friends car is just about done from Bullish racing. He is upgrading to RC 720's and said that I can have his stock ones. They are 550. I realize I will need some type of fuel computer. I will probably just wait til I get Hondata, but will these idle with a safc? I was told these are peak and hold so I would need a resistor box. But will they fit into my fuel rail?
Oh yeah, hes got a 94 TT supra.

if they fit a denso rail then sure, you will need something like you mentioned to control them though.

I don't think they will fit a Denso Rail, and you might hafta do something fun with the plugs. If you can get them to work...sweet! Do a writeup.

FYI: The DSM 450cc will supply all the horsepower your stock motor is going to make. Well, they should...

Tell your friend if you can't use em, I have a buddy with a 3rd gen Supra that needs a set of 550's.

PLEASE let me know.

I'll let you know shortly as I'll be picking up a set this weekend. I ran 315cc/min 7MGE injectors in my B16 with no problem. Just used some Zdyne BoostTight seals and soldered the 7MGE's injector clips onto my wires.

I do believe stock supra injectors from a TT are side feed, not top feed.

86-88(low resistance) 89-92(high) RX7 Turbo II injectors are 550cc and would work.....I think there is a guy on partstrader that has 6 of them for sale at $40 a peice, they're the low resistance models thoguh dunno if that helps or not.

Just talked to RC, supra injectors are side feed so they dont fit
