how can you tell what stage turbine wheel you have in a garrett t3 turbo?

 

you'll have to measure the inducer and exducer sizes of the blades than look it up to see what "stage" it is. Or just accept the mm measurement which means more than the "stage"

 

my main thing is that i baught the t3 t4e 57 trim turbo from down2turbo off ebay, and after my warranty is gone i plan on upgrading the exhaust housing to a 63 trim housing, i am just hoping that it will fit correctly and everything 2ndly is there any place that i can get a 60ar or 70ar intake housing that will fit over the 57 to4e compressor wheel, i have a 70 ar intake housing from a t4 but the wheel is like 2-3mm's bigger than the whole is so i know there is no way in hell it will work.

 

why not go to a stage II turbine with the .48 housing... I believe thatll flow better than the .63 stage I... i could be wrong tho

 

is the turbine wheel that comes with down2turbos t3t4e a stage 1 wheel? i would suspect it to be a stage 3 wheel, buti am just wonting to find out for sure.

 

hey sorry for the O/T, but i PM'd/emailed you BMC regarding info about the manifolds and havent gotten a reply...i'm really interested in purchasing one but have a few questions, if you can get back to me through PM or email me at infinityracr@hotmail.com, i'd really appreciate it...thanks

 

well turbine wheel stage has an = affect as a/r. however even with a .80 a/r a stage 1 wheel is only 48mm in diameter meaning that even though your housing is huge internally it still has to flow thru that damn tiny wheel. that should answer 2 questions with one stone.

 

When you buy a stage 1 turbo kit and a stage 2 and so on what is the diffence? I just thought bigger wheel different houseing. Maybe better manifold and misc. stuff like that but whats the true difference? Just better top-end and a bit more lag?
