You can get to the 300hp mark on the .48 housing, but the exhaust restriction is rediculously high at that number. The .63 housing will outflow the smaller one all day, but comes on a bit later if you don't mind the little loss in bottom end power.

 

what other turbine housings fit on this turbo? someone gave me a ebay china piece of ---- turbo today and i was gona swap the turbine housing cause he said it was a .63 but when i looked at it the exhaust outlet hole where u can see the turbine was like 1/2" bigger

 

THen go ahead.
The chinese turbine housings are in my opinion very good, if not better than garrett ones because they don't tend to crack as much across the wastegate hole.
However, I am not sure of the accuracy of the a/r of their housings.

if it's ½" bigger, it's because it'S a stage 3 turbo and you got only a stage 1 wheel!
big problem! you need a good, non-chinese stage 3 wheel now!

 

forget all that, i just need to know what housings fits my wheel

 

Prolly a stupid question but are the .48 and the .63 wheels the same size and the only difference is the housing? I have the .48 and wanting to go .63. Sorry for the threadjack but there's alot of good info here.

 

There's no "0.63 wheel"! the a/r ratio concerns the housing only.

If you have 0.48 a/r now, you can just swap a 0.63 turbine housing by yourself in 5 minutes, just make sure it's a housing made for the same wheel size as yours. (which i believe is stage1)

 

so all i know is a .48 or .63 housing MIGHT fit mine.. what makes a turbo a t3/t4 hybrid? cause thats what the ebay one was i was gona swap housings from

 

The compressor side. Exhaust side's are t3's, just usually have a larger stage wheel. Then the T4 compressor side is mated to the fast spooling t3 hotside. Pretty basic sutff dude...how long you been here? LOL

 

ya i never dug into it cause i always have used mitsubishi turbos, there cool but i think its gona be easier to deal with t3 flanged ----

 

Yeah! nothing like a good old disproportionate t3/t4 !!
