R34 OEM Turbos

I have found two of these going cheap and and would like to rebuild one and get my recently layed up 320 project on the go

the spec is below

Part# 14411 AA300, Comp Housing is a T3 with a C100wheel. A/R is .53. Turbine housing is a T25 w/GT25 wheel, A/R is .48 Max BHP of airflow is 225. These turbos will break after prolonged use over 14.7psi as they are ceramic

do you think one would be big enough on my engine - i reckon it will spool up nicely - but will it choke the top end ?

any help much appreciated

Would have thought it would be fine for a 320(?) but the reason the skyline boys change them is because they can't load them too much. My T2 runs 20psi all day long.

cheers andy - its an m20b20 so should be fine with the low boost levels

I dont think i would put more than 10psi through it any way so hopefully the blades should hold out

what spec is your t2 and whats it boosting ?
