i have a 96 gsr with a greddy turbo kit. i was wondering if you guys know what it is safe to boost up to. i have a custom actuator set at 3 psi. i bought a manual boost controller and bumped up the boost to 5 psi. once i tried to go to 5.5 - 6 psi my O2 sensor went from .95 volts (stock) to .89 volts and my timing went from 17-19 degrees (stock) to 16 degrees. do you guys know if this is still safe? i want to go to 7 psi but i dont know if itll be safe. i'm using the blue box and i thought that its safe up to 7psi. should i worry about the change in O2 and timing? i used a palm pilot and data logger to find these values. any help is appreciated, thanks.

come on, some of you must know whats safe to boost with a greddy.

I think you will be fine boosting up to 8psi with the kit. You might be pushing it going up to 10psi, some have luck others dont. I am not sure on the timing part though.

dfoxengr

well seeing as how you are getting richer, and timing retard, these are both good things when boosting and you will definately be fine

clu

so will it be safe for me to run 6-7psi (non-intercooled)? because when i was trying to go from 5-6psi my timing and O2 went down a little so i thought something was wrong and i turned the boost back to 5. do you guys know how low is bad for O2 and timing? is below .89volts bad for O2 and is 16 degrees bad for timing?

Stock timing should be 16 degrees. Non-intercooled i wouldn't run more then 5psi. Get a intercooler you will be happier,and so will your engine

clu

but my timing was a lot higher than that stock, and once i set the boost to 5-6psi it went to that, so i should be safe to go to 6-7 right?

Well you need to adjust that then. Advanced timing + boost isn't good esp if you don't have any for m of real (programable) engine managment.
Like i said before 5psi max w/out a intercooler, your going to have some hot intake temps.
Stock timing should be 16 degrees (idle) it advances under load (acceleration). Some people run their timing retarded to prevent detonation (12-14 degree's). So you will be fine.

so im pretty much stuck at 5 psi? i thought the greddy blue box was good up to 6-7psi for a 96 gsr. my friend has a civic ex and hes running 4-5psi, and he told me that he heard the gsrs can run from 5-7psi safely.

Yes you can! If you bought the kit as a whole, then there shouldn't be a problem running it at 7psi with the blue box. I even ran 9psi on the blue box with no problems.. on higher octane. I'm not undestanding as to why you wanted to rig up the actuator arm just to get 3psi and then add a boost controller just to get to 7psi. Doesn't make sense at all.

Anyway, if you already have 1 step colder plugs, that's even better. Otherwise, if you want more power, get a larger diametered turbo back system.

Once you get a intercooler you can up the boost.
