ok guys, i had a massive 36cm housing for my 3b that obviously wouldnt spool.
i looked forever and finally found what i wanted. holset 23cm housing!!
my only question is the housing has 23 on it. it has 23 stamped on the inlet.
and i matched the part number to a 23cm
my only question is the two housings are indentical in size physically.
the 23s demensions are just as big as the 36.
is it the internals that are different? the way they are desined in the inside?

 

bump anybody?

 

The 23cm housing is the divided one. I believe 23 cm, refers to 23 cm^2 (area) for air to enter the exhaust housing? The holes should be smaller. Atleast I hope since I have the same exact housing.

 

yeah i know its a 23cm, it says it all over and i matvched the part numbers,
it just through me off cause externally its the same size as my 36

 

External dimentions don't mean poop though that's a big size jump and it seems like it would. Google A/R. And you should get some good explinations.

 

i understand a/r. like i said im sure the internals are whats different.

 

I belive the number of cm is the area of the scroll outlet only.

 

yeah, i know its a 23, the internals must just be alot smaller

 

gunna post some pics later tonight of the housing, see what you guys think

 

heres a few pics guys, it says its a 23cm and the part numbers match. it just seems big externally. but i guess the size is all configured internall right?
