Gtr Turbo Identification

[LuckyTune]

Hoping someone can help identify these turbos, came off a 33 rb26 and I'm not sure if they have been rebuilt or are not standard gtr turbos (given the steel turbine)

Turbine also appears to be larger than a stock gtr turbo although I haven't measured yet

[LuckyTune]

For comparison here are some freshly rebuilt standard 33gtr turbos and the ones I just pulled off, standard ones have smaller turbine and compressor

What does the plate on the core say?

[LuckyTune]

no plate, the only numbers i can find on them are pictured unfortunately

i would say high flowed factory turbosl, but that one is f**ked

[LuckyTune]

haha yeah, just my luck it happened on about my 5th lap first thing in the morning at wakefield...

am i likely to need a new tune after the standard turbos go on?

[r32-25t]

I would at least have it put on a dyno to have it checked and then they will be able to tell you if you'll get away without a tune or not
