As Matt said T3.48, the .48 is the exhaust housing size commonly used on a stage 3 hybrid.
Even if you build it yourself, it will need balancing by a pro.
that is quite simply nonsense imo.
the shafts and wheels are balanced.
I have built quite a few t6 large frame diesel turbos and they run 1 bar of boost 11 hours a day flat out and havnt had one fail yet.
ive also built 2 Renault 1.9dci turbos (which had both catastrophically failed and seized up) with ebay shaft and wheel kits for £110 no balanceing and they run 1 bar of boost no problems both been running over a year now.
for a big boost engine id probably want to get one checked as the wheel speeds get silly high but it seems to me the op will only be running a bar or so of boost.
op I have also used the cheap t3/t4 turbos with great success on a yb but they would be useless on a 1600 cvh rs turbo unless your gonna rev to over 8000 rpm.
I just noticed your actually 1800, you have the option of a yb t3 with the 0.48 rear housing which may be a better option with the extra capacity.
