Have you tried porting the turbine housing? External wastegate? WGA with a longer throw? I know that doesn't answer your questions, but those are some other solutions to evo3b16g creep. Running 25psi would be more fun, though!

Looking at your profile the only thing I see missing is a good frontmount intercooler, alternatively you could use water injection(water injection is cheaper but you have to refill the tank.) The 16g(all the variants) heat up the air quite a bit at those boost levels.

one more thing, while not related to your problem I see you don't have a fuel pressure regulator with a walbro 255, how is your low fuel trims/idle????

Looking at you mods, I would think you are good to go. Just log your runs and see how much timing is pulled. You could also look into putting a intercooler sprayer on it, just search on here there is write up on how to use your rear windshield sprayer as a FMIC sprayer. Might cool things off a bit. I see you have engine work done so I would assume you have a newer headgasket and ARP Studs right? If so I think you'd be fine as long as your clutch holds up.

Enjoy!

Like always, log your pulls, one of the better ways to monitor how things are going.

With stock head studs, if your tune isn't solid, you will most likely lift the head.

FMIC = front mounted inter-cooler. your system looks good to me for 25 psi safely, I am assuming that the big 16g has the appropriate wastegate and bov. i'd more highly recommend taking a look at your belts and such if you're concerned with it being a reliable / safe vehicle.

I agree that you should get some headstuds. I bought ARP headstuds, not pricey at all, also you can do your head gasket at the same time, with a nice mitsu head gasket. Also that FPR might be nice to have to, you dont want to run to lean....is your fuel pump rewired as well?

i do have a FMIC but its not hooked because of price of pipeing, they have some ceapones at ebaybut, are they good?
and no idontknow why i dont have AFPR, where can i look for aq cheap one?

what have you done for tuning? You may have to pull timing a bit, 25psi is really hot on a evo3 especially after several pulls. Your bound to be knocking if you dont have a fmic.
Id say pull off that turbo and port the mess out of your waste gate hole ( in the o2 )
and port it to the point it cant be ported no more and that should at least keep you below 23lbs. ( Unless your not telling us something, like your running open dp or something. )

open dp? downpipe? a have a 3 inch turboback

25 psi is quite a bit to want to sustain.

ARP Head Studs
Mitsubishi OEM Metal Head Gasket
since your on a 16g, 650's or better yet 750cc's.
190 FP rewired (minimum)
Full 3"

Fully functional seat belt!!!

best of luck in all...
