i have a sr20 with the stock t25

-stock 370cc injectors
-stock headgasket
-stock internals
-3 inch exhaust from the turbo back
-blitz FMIC, blitz blowoff
-walbro 255 fuel pump
-stock MAF :[

i was wondering if i could bump up my boost from 7 to 10psi safely......

i mean with like no problems what so ever as a daily driver.

what would be the expected power increase?

you could have gone 10psi stock all day long. as far as power increase,most sr20det's lay down anywhere from 167whp-178whp stock,so maybe 200whp is a good figure for that level.

im runnin an s13 sr

all stock with fresh gaskets.
t28 ball bearing turbo
full 3" exhaust
walbro 255lph
on 10psi stock maf....and honestly im still too rich the wideband reads rich at idle and perfect under boost

ima be running 12psi.

just get a wideband and watch your air/fuel.

you can run up to 12psi with no issues

With a stock SR running stock injectors you start to run lean at 10.87 lbs. When I was running my stock set up I had boost set to 11lbs. 11 lbs is a safe bet anything above and your starting to run your injectors lean, keep that in mind.

you guys are pussies. 93 octane in the winter and 14lbs(or whatever that tiny t25 will push out). Never had a problem with any of the swaps that mirror your set-up.

now in the dead heat of summer...no.

10psi is no problem. I've got an S14 motor with the t28 and i've been running 16 for a couple of years now. Go ahead and turn it up.
