I have a HKS T51R SPL turbo that I am trying to find out if it is the BB version.

Here are the numbers on the identification plate :

MODELL: GT4594LR
P/N: 14201-00z17
S/N: DF 0444J
GTI P/N: 703654-12

It is supposed to be BB , but I want to be 100% sure .

The HKS label should state BB if it is BB

SPL BB should have a gold anodisednut on the compressor.
SPL normal has a purple nut.
KAI BB has a green anodised nut.
Std Kai is a silver nut.

It s got a standard grey/metal nut (I guess I could call it sliver)
Blue Sticker on comp housing just reads :
T51R
SPL

Then HKS under that .

Then I'd say it's not a BB. Which probably means it will last longer.
