SVO 42#'s - Installed ! I was swapping my Stock SS 28.8#'s to 42#'s (green top) SVO injectors.
Thanks to an awesome write up by WS6FirebirdTA00 https://ls1tech.com/forums/fueling-injection/309057-how-fuel-injector-swap.html
It took me 2 hrs to do it.
Everything went smooth. I used vaseline (100% petroleum Jelly) to lube up the o-rings. They went it very smooth. I had no leaks whatsoever.
When I fired up my car, it idled and surged pretty bad. Idle would not stay above 400 rpms. It's expected as injectors spray almost twice as much fuel as they are supposed to.
I'd like to thank one of our collegues "REDHARDSUPRA" for tuning those with HPtuners. He stopped by with his tools and got it tuned in a matter of minutes. It was a simple table conversion, and when I restarted the car, it was normal again: Idle at 850, and no surges. We took it for a spin, and it felt different (in a good way) It seemed like it was a lot more responsive. But again - maybe it's just an illusion.
Anyways, redhard supra took some readings, and with 42#'s my duty cycle is at 0.47 at 6000 rpms. A LOT of room for improvement.
In a few weeks I'll be putting in an F10 cam, so I definitely need that.
Thank you all for help
