They have got the following markings:
91x
inp - 058
n275h
they are also marked with a small whipe of green paint.

 

They are dsm injectors but not 450's... I believe those are 275cc injectors.

 

so these are no 450 blue tops?
is anybody sure?
is there someplace where I can check this?

 

I am 99.9% positive that is a 275cc injector.

here is a good site with pictures of MANY common injectors including dsm 450's (unfortunately they dont show those you pictured, but I am saying 275cc given the part numbers you supplied and other injectors used in dsms who use a similar part number system.)

these are what you should be looking for:
B450L casting #INP-009 (450cc Low Impedance)
MDL450 casting #INP-018 (450cc Low Impedance)

I believe my DSM 450's are yellow...

 

what would be the max hp?

those are not 450cc injectors, those are the 510cc injectors from an evo if they are yellow tops from a 4g63.

 

what would be the max hp?

 

my 450cc dsms were totally maxed at just past 300whp (I managed to pull 335whp on the dyno with them in my low revving f series motor but it was starting to lean out)... just at or around 300whp seems to be the trend with most people who have pushed them to the limit.

510's obviously you could get a little more.

 

The 450's I've 'collected' all have 450 stamped on the side in the plastic. I'm 99.9% sure that the 275 in your PN indicates 275cc.

275cc injectors would be good for 210whp with HIGH fuel pressure (walbro 255HP 60psi+) and a good motor like a stock GSR. In other words, quite useless for boost.
