On what? 35r? Thread's about a stock turbo.
And if you're talking about a stocker you're full of BS. All 26 pounds of it.
No studs needed for stock turbo power levels.
To the OP:
You probably won't need bigger injectors with stock turbo, because it will taper to 19-20 psi by redline anyway. You do need to look at fuel though - better gas, E85 or alky is needed for higher boost.

he is right about the headstuds for insurance, without doing that your cutting really close to the factory safety margin, infact your out of the saftey margin. if he knocks at high load running 26psi that headgasket will give away pretty quick. mitsu alreaady had 5psi safetly margin boost (to 25psi) so 26 is already over that.
If you're pulling the head anyways then might as well. But I won't do mine until then.

Power/torque is not measured in PSI of boost. So there's no such thing as "mitsu alreaady had 5psi safetly margin boost (to 25psi) so 26 is already over that." Sounds like a good line for next installment of Fast and the Furious though

Throw a JDM MAP on that and see.
Agreed, well, for normal people that is. Now, me on the other hand, my turbo is becoming some sort of wacked out crack addict on speed. I am getting very close to 26psi by 7500 rpm, but, my stocker has been bastardized by my hand in so many ways it's not even funny. Plus, at 26 psi by 7500 rpm the hot air comming out will probably fry my egt probe anyways.

I *lightly* disagree with this too. I have some logs I can chare that show 29.5 psi with 32 counts of knock from 6,000 to 7,500 rpm's with all stock head crap. And I managed to do it about 7 times in a row. Oops.

I just did a highway pull and I was wrong. I hold 26psi until about 6000 then tapers to ~24psi. I guess I just never noticed it tapering down. Anyways, to the OP you can definitely run 26psi with great driveability and reliability.
