Injectors and fuel rail
So I'm getting close to being finished with my NA-T build. Have the FMIC on and pipes routed, installed the wideband o2, my boost gauge, and the AFC Neo. Just needs the turbo/manifold itself installed and things routed up. I gave a call to my tuner today and he let me know it would be a waste of time not to get a set of 450cc at least, but prefers 550cc injectors for my planned setup. Not going to argue with him so I'll bite the bullet and order a set when I find one. He also said to upgrade the rail because it acts like a fuel reservoir and will make it much less likely to ever lean out. Just being more fuel available I guess. He agreed that a return system and external FPR isn't necessary. But he said the rails are a dime a dozen for these engines and around $50. Problem is, I can't find any lol. I've searched around the normal places. But not seeing any rails for the GE. Any suggestions? And I also need suggestions on some 550cc injectors.

I've already found that the GTE rail will not work on the GE, so no aftermarket ones for the GTE will work. Neither for the 1jz either. I need a rail on the cheap and willing to go a little more on the injectors. But need suggestions. Don't have a lot of knowledge about fuel systems for these cars. I just know that all I am seeing so far is for 1jz swaps and 2jzgte engines.

Can anyone tell by looking/reading about these if they will work? https://www.extremepsi.com/store/FIC...et-High-Z.html
I know the GTE uses side feed and going to top feed is an upgrade for them, which these are probably intended for. But we already have normal top feed rails.

Here is another option for the IS300, but I think would work. https://www.deatschwerks.com/22s-03-0550-6

However, plenty people have used a modified stock rail to make a lot more power than you will (I'm talking 600+), so an aftermarket rail is not a necessity for a mild NA-T.

Yes as I am looking into this, it seems like an $800+ ordeal to get a rail, the fittings, and injectors. I think with some 550cc injectors and my Walbro 255 it should be fine. Still thinking about it. Just having trouble knowing what injectors to go with.

I'm really leaning towards this set of injectors. https://www.ebay.com/itm/550cc-BOSCH...a/192981179424. The seller seems to know a bit about the fitment and they seem high quality. Best price for a decent set I can find. Some sites like ExtremePSI sell the same set for more and they consider them good quality too.
If anyone has a reason I shouldn't get these, let me know. I'm in no hurry to order because I still have a lot of the NA-T kit to install. So I'll give some time for opinions. I don't like Bosch parts in general. But these seem like a good buy. And I am already relying on a Bosch wideband o2 that the AEM kit uses. So I guess that bridge is crossed.
