Long story short..
I can't seem to find any info online about it, but will an MR2 3SGTE fuel rail and injectors fit straight up to the 3SFE intake manifold?
It's for a turbo project and this would make the fuelling requirements nice and straightforward.
The problem that I have is that I went turbo and I need larger injectors, like 550cc, maybe more. But, I would like to know if the 5SFE fuel rail can do the job, OR, make a custom rail. Right now, I have Supra 312cc with my stock 3SFE fuel rail.
I'm not sure about Aussie emissions standards, but your stock injectors are really all that will play nicely with a stock ECU. Now, if you don't have to worry about that, or better yet, you have an aftermarket ECU, the JDM injectors offer 320 flow rate over the normal 280. They're skinnier, longer, and tan.
I have Supra 312cc N/A injectors, and it's running dry as a day before the election. ECU, Megasquirt PNP2, and the numbers say I need more fuel. Also, I'm running a ported Celica manifold with a V6 throttle body, adding more air. My tuner said that 550cc will do the trick.
BTW mate, is the fuel rail from the 5SFE larger than the 3SFE Fuel Rail?
I knew about your throttle body but I had no idea you were running Supra injectors! From what year model? fiveomotorsport.com might have what you need, Mensa.

What still puzzled me is about the 3SFE/5SFE fuel rail. I checked online and they are the same. This is the Celica 5SFE 95 fuel rail. This is the RAV4 3SFE fuel rail. They are exactly the same.
Off the part number, it seems like any 1993-1997 injector for the Supra 2JZ would work here. Check the link, there are some crazy high performance injectors. Range of 550-1200cc.
