I purchased (4) MKIV Supra 550CC injectors for the great price of $150

However i'm having issues of them fitting in my Redtop SR Fuel Rail. I searched forums and havent really hit on anything about this. I was aware that SR guys have used these sidefeed injectors w/ stock rail but i guess i could be wrong.

Is anyone heard of or used these MKIV Injectors in their SR's

it was my understanding that neither the nissan plugs fit them, nor do they fit in the rail. but ive never tried it personally. i was looking to pick up some myself, but read they didnt work when i searched a while back.

im sure they could be MADE to work somehow, assuming its a high imp. 550cc injector, the ECU will fire it like any other, just gotta make it fit
