Which of these injectors seem best??

Hey guys, so I have a 98 GSR that I will be turboing come spring, and i'm trying to get all my parts ahead of time and only have a few things left. I purchased some RC 450cc injectors off craigslist that have like 300 miles on them for $90, but my friend has an accord that he just finished getting tuned after his turbo set up got finished, and had that same size injectors, and they maxed them out at 250 HP. I know it's a different engine, but I feel like it's probably best if I just upgrade now since I have the money, instead of having to get it re tuned (the place it's getting tuned isn't close.

My build turbo set up will be a t3/t04E 60 trim, walbro 255 fuel pump, obd1 ecu, custom exhaust, all the supporting stuff to go along with it (I have all the parts except the right size injectors) and I want to make around 275-300 HP with room to grow, hence the reason I want different injectors before the tune. The shop he got tuned at reccommended 1000cc's, so I found a few that looked good to me. Here they are

Now, a few questions if I may. Do I want the to be Low Resistance injectors? I remember reading somewhere that some rejectors require a resistor box or something for them, but I still don't completely understand the difference between Low Resistance and the other kind. My other question is, will higher injectors have a different idle? I also read somewhere that some injectors if they are large cc will change idle?? Sorry if these aren't good questions, But thanks for any replies, and if you guys have different recommendations on injectors, let me know!

No, you want high resistance, aka saturated injectors. No need for resistor box garbage. Its not important that you know the difference, its irrelevant. Just go with the more modern and easier saturated injector.

Both injectors you linked are low resistance, aka peak & hold injectors. You dont want those.

I assume you will be running gasoline. 550cc will support about 350whp, 750cc will support about 425. If you want to go bigger, the new Bosch EV14 style injectors are very good. In the old days there was a trade off with a large injector where it had very poor low pulsewidth performance. This trade off is not true (as much) with modern injectors. ID1000s are a perfect example of a larger injector with excellent pulsewidth performance. This means you can run a LARGE injector and still idle lean. If you can afford them they will give you lots of room to grow while having none of the trade offs of those older 1000cc injectors you linked from RC and Precision.

So at minimum you need RC550s, but 750s are usually can be had for the same price. But ID1000s are highly recommended. Five O Motorsports also has some inexpensive injector options.

I'll need to ask the shop about the brand 450s I have, but he maxed his bishimoto 450's out at 250 hp. I'm not sure if they differ brand to brand or not??
