would it do anything if i put the HO injectors on my 98 z24 with the LD9, i have the ho swap done.
just wondering let me know

Stock injectors are more than sufficient for your car.

Yeah, you don't need bigger injectors unless you've done a TON to your car N/A (and I think you can probably adjust for even an all out N/A setup by simply bumping up fuel pressure on stock injectors, I might be wrong though). Installing bigger injectors without having something to tune them (and you'd be tuning them to put out the same amount of fuel as your stock ones did, if you did tune them) could really cause you to waste gas, as they'd probably dump more fuel in than you need. More fuel would in fact give you LESS power, unless you have a way of getting more air in there to burn it with.

Too much fuel abosolutely kills your power. We switched back to stock injectors from ford brown tops on Paul Tjepkes's (N/A Madness) motor, and gained like 4 car lengths on my BMW.
