2jzgte injectors? looking to run E85 on a blacktop 20v
fuel injector upgrades for blacktop20v?
Re: fuel injector upgrades for blacktop20v?
im not sure but the sr20ve and the sr20vet injectors might fit. they are 350cc for the non turbo and 440cc for the turbo model. they are bottom feed instead of side feed tho.
Nissan SR20ve & SR20vet injector.
yes the 2jgzte injectors will fit they are rated at 550cc i think the 2jzge uses different type of injectors.
the nissan sr20det injectors (370cc) will fit too but are a little shorter then the 2jzgte injectors.

You can also click through the pics at witchhunter and when you find one that looks compatible search the part no and see what it comes out of and get more info on it.

2tz-fze.....previa s/c van injectors are a direct swap into 20 valves and are available here in the states i believe they are 425-450cc...sr20 are side feed but they dont fit properly.

Why are you looking at such big injectors?
E85 shouldn't need more than 30% more fueling. I would expect a good bit less.
Stockers are 310cc right? 310*1.3 = 403
440s would give you plenty of margin. And are available in a number of cars.
23250-46040 23250-46100 23250-76020 Those are all high impedance as I believe the BT is stock. Looks like the 3S 440s along with the 2JZ 550s look like they are low impedance. 23250-74090 23250-46060
Impedance shouldn't stop you if you are controling them with aftermarket engine management but it will be something you will need to be aware of when setting them up.
Bigger injectors will just make it harder to control fuel down low and will give you no benefit.
Re: fuel injector upgrades for blacktop20v?
my tuner suggested 500min.. and some have suggested doubling the the factory flow to run e85..

I guess you are kind of right on the cusp.
I bet the 440s would be enough but probably on the low side.

at 500cc, it sounds like he might be running a turbo. otherwise, 500cc is way too much for any n/a built engine

Before yesterday I would have agreed with you but if you use either of the calculators on the page I linked to they suggest at least a 460 or more. Since the injectors I know of jump from 440 to 550 then the 550s might be the best choice.
That is based off one of the calculators just entering the stock injector size and the other calculator entering the HP. I entered 180 HP then used a very good BSFC which the BT has. Whatever the case both calculations were for 100% E85 at very near stock power levels. Like I said in my earlier post I'm pretty confidant the 440s would be enough but if you could find 550s then why not be on the safe side with some room to grow if you ever needed it.
