680cc Injectors for 1JZ, other then Venom

[viperkillertt]

Hey,
I finally got my dream Garrett GT35R, so it is time to complete the job. I need some new injectors, wastegate, and fuel pump. My main question is about these injectors i have found on ebay. Has anyone used them. Do they work with the 1jz fuel rail well?

Update: Venom is very bad!

So what do people suggest for 680cc injectors?


Thanks for looking and helping!

500-550 is the max the 1jz side feeds and rail can handle its a very restrictive design and even if you fit the higher flowing injectors in the rail the spray pattern would be crap Its recomended you goto top feeds and after market rail dont worry the top feed uses RC injectors much cheaper then toyota high impedence side feeds.

Try to use the smallest injectors rated for the HP you plan to have if you go to high you end up with harsher idles and harder to control fuel amounts at the lower duty cycles.

So if you make 6-700 hp at the crank go 750
5-600hp go with 600-650
etc.

My GT35R was rated for 650-700HP so I went with 750cc

Yeah, that is why i decided to go with the 680s. It seemed like the best fit. I did the calcuations in class about a year ago,b ut i dont remember exactly what i got. i could redo them, but i am lazy. I think 680 will fit well. But if i do need a 200 dollar fuel rail, i guess i might go with some 550s for the time being. thanks for the words.

make sure you get the correct ones. so far youve been listing top feed injectors. stock 1jzgte and 2jzgte rails use side feed. so if you plan on gettin decent sized injectors get the driftmotion 1jz rail.

^^yes i would go with the driftmotion 1jz fuel rail and driftmotion's seimen top fed injectors

how about 2jz 550's with fuel rail? can get both for about 200
