As said in the title, looking for someone savvy with turbo sizing to either help explain or guide me to another thread that help covers different turbo sizing and how that relates to gasket sizes.

Hope this isn't an over done question as I've spent the day researching but can't come to a solid answer.

I'm planning to do some preventative maintenance that requires me removing the whole turbo kit and with that I would prefer replacing all gaskets that I remove. While the SBD500X is a custom in house turbo built by SBD, I understand that it closely resembles or even shares the same housing as a GT3076R as quoted here before. I'm trying to preorder all the needed gaskets before needing to remove everything since my window for this is small to do this.

So bottom line, is there any tall-tell signs I can see that'll tell me what size gaskets I need, specially for the turbine exit to down pipe and from headers to turbine, or how I can differentiate what a T2/3/4 etc etc size turbo looks like.

Thanks in advance for any answer!
