I have searched a good bit and cannot find info on any specific turbo type with my combination of wheel sizes and housings. I'd really appreciate some help as I am trying to research this turbo for potential use with my new build. I don't want to get inducer and exducer terms mixed up so I will just say the exhaust wheel at the outer tip is just a hair over 63 mm and 72+ at the base. The compressor wheel is 65 mm at the outer tip and 90+ at the base. Pictures of housings and wheels are below.

Any idea what it is?

Thanks - Charles
 
Charles, because it's a Precision .63 turbine housing, here is a screen shot of what Precision did at one time. Today it seems they've forgotten they did buick turbos since Harry H. was bought out.

Thanks Anthony P. - I was looking for a chart like that earlier but couldn't find it. However, based on my measurements and Bisons comments, Im not gonna find my turbo on a typical mfg list. Thanks though!

Thanks Bison! So who makes the T0476 turbine? Also, can you clarify your "6/6. 9 Sec..." comment?
Any thoughts on how this thing would spool compared to say a 62/62?

Thank you !
 
P trim turbine. Compressor 6 full 6 splitters. It will spool slower than a 6262 but will support the same power or very close to the same power. I’m not 100% sure the 62 exhaust wheel gets 100% of the 62 compressor wheels

Great info Bison, thanks again. Since I'm only looking for a mid 10 second combo I'm thinking I need to hang onto this Turbo. I wonder if it is upgradable to ball bearing.

Charles, you have a super knowledgeable source helping you. glad bison had a few moments to see your thread and provide the answers. I saved that page from precision's website years ago. i don't believe any of that stuff is on their website anymore.

You need a 10 sec converter. Probably the most important thing

I know you are a big fan of the PTC non lock up but I am running a Husek 3021; hopefully that will work well too. Thanks again.
