hope that gives someone an idea ?
is there any guide on reading compressor maps ? would like too learn and i think if someone posted a lil thread a about them quite a few people would benefit!!!

That turbo looks decent for an AAZ to me. A bit on the big side maybe, but it's good on it's own for 25psi easy, even 30 shouldn't be much trouble. It likely won't spool super quick though... it appears bigger than a K24
When I get home, I can find a guide to reading compressor maps, I'm at work right now though. If you google, a few things should come up. IIRC, Garrett's website has good info

looks ok from what i can tell, but i am not that great with compressor maps

i think 30psi would be too much maybe 25 at the very most and even that i think would be over spinning it

add a smaller turbo to help spool the bigger one

honestly i don't think this will be too big at all, it will be a good turbo for 20-25 psi

The compressor side of this turbo looks like a good candidate for a AAZ if head is optimized.
Calculations and plotting I just did:
The four points on the graph:
Green = 1bar/15psi boost @ 2000rpm
Yellow = 1.7bar/25psi boost @ 2700rpm
Orange = 2.0bar/29psi boost peak @ 3000rpm
Red = 1.7bar/25psi boost @ 4500rpm
If you run the turbo with max boost 1.7bar/25psi it would produce somwhere in the region of 175hp/230ft-lbs (crank numbers)
If you let the turbo peak up to 2.0bar/29psi in the middle range you would gain some torque, somewhere around 175hp/255ft-lbs
If the turbine side of the turbo is matched to the 1.9 litre displacement to support this boost curve is a different question…

that sounds promising
