ok guys i've searched like a mad man and can't get clear answers, just ones that contradict eachother. First off i have a 1jz single turbo sc300 and my friend told me that the 440cc JDM injectors go right in with ZERO modification, and that the 550cc USDM won't. when i looked this up i read like 10 different answers. So i want to get this clear, any of you guys with a 1jz that put 2jz injectors, were they direct fits with no mods, which ones did you use, and was just splicing the wires all that was needed????? Please help my tune is coming soon???????
