PLEASE help me pick correct fuel injector

[hsk8te2006]

Hi Everyone,

I have searched and haven't found any guides that can help me figure out my new problem.

I drive a 1996 GS-T Spyder, and have been running my car nearly stock. It seems that one of my fuel injectors has died. That said, if I am going to replace one, I'm thinking maybe I should just go ahead and replace them all, and upgrade while I'm at it.

Here's where I need help from anyone that is certain they know what they're talking about... Will it be of any benefit at all to upgrade fuel injectors on a nearly stock car (removing wgs restrictor and getting a mbc soon)? Such as, will it allow me to up my boost above what i was planning until now (15 psi)? (Come to think of it, if the supporting mods are in place in the future, how much boost can the stock turbo handle before blowing up?)

Also... I have logging software, but no ability right now to adjust fuel by tuning, and I'm not sure if I want to go into that expense yet or not. So, what fuel injector size can be handled by my stock fuel pump and ecu?

I guess if I am going to look down the road, ultimately is there some sort of chart or guide as to what size injector can reach what hp or boost level properly?

And lastly, while I have your attention, will an upgrade in boost by a few more psi, and an upgrade to injectors, balance each other out?

Thank you very much for your input.

just put stock size injectors in. If you plan on upgrading the turbo later on, thats when upgrading the fuel pump, FPR, and injectors comes into play. Say you were to go with a 16g or something close to that, then 550cc's will do the job. If you go bigger, like...a 50 trim minimum of 650cc's.

It will not help you out to upgrade the injectors if you are planning to keep it nearly stock. A mbc on a stock turbo will not put out enough boost to require the upgrade of injectors. You dont ### to take the stock t25 past 15-16 psi cause you will just be blowing hot air and wont make a difference.
