Rear Housing

[t04z]

I am currently running a t3 .63 garret rear housing on my hybrid turbo but am want to change to twin scroll .84ish do I have to match my rear wheel size to the housing or what got told doesn't matter as long as its another housing to suit a garret is this right ?

[ARTZ]

is it a gt30 core?

[t04z]

Nah I dunno what the core is that's the problem

[ARTZ]

well yes you will have to find out what size your turbine wheel is..if its gt30 it will be 60mm but if it gt35 it will be 68mm

do you have a serial number off the core

[t04z]

Haven't taken it apart yet will tomorrow where's it usually written thanks heaps for your help dude also do u measure the induced or exducer for wheel size

think its the inducer

[t04z]

Haha yea big one on the rear is the inducer big one on the front is the exducer

[ARTZ]

yep..in is where air comes in and ex is where air goes out..it all makes sense now..

Definitely need to know what turbo youve got before you can select a housing. You may find replacing the housing will fall short in benefit to replacing the whole turbo.

Can you please state what your aim of changing the housing is so we can comment on a better solution if possible?

Also, not knowing your turbos actual spec gives me the impression it may be a cheaply made thing and you could be blowing hard earned dollars in the wrong way. There are many options around the $1k mark these days that will easily replace what you have and possibly exceed your aims for the change.. Chances are buying a garrett housing OR moddifying another one to suit your 'hybrid' turbo will cost similar money and wont necessarily hold the gains you seek.

And inducer/exducer refer to the smallest and largest diameters of the wheel in question respectively. Irrespective of compressor or turbine.

Just to clarify.

you sure bout that? isnt the inducer the diameter that draws the air/gas in and exducer the diameter that expels the air/gas?? so the 60mm being talked about is the turbine inducer diameter isnt it??

i wasnt copying your post,

Nag its not a cheap setup the previous owner spent 3500 on getting the turbo custom made buy a bloke here reason I'm changing is cause it was on an Sr20 and its now going on a 26/30 so going a bigger rear and also I have a twin scroll manifold so need a housing to suit that forgot to get turbo today so I will get it tomorrow and take some measurements

yea thats a nice simple way of looking at it

[t04z]

took apart my turbo and its a 68mm i measured n got 67mm so guessing i was a little out tricky thing to measure it had 1269 written on it dose this mean anything to anyone so i guess its a gt35 wheel

[t04z]

so took a better measurement before didnt have the right tool before was just going bye eye n a ruler lol

turns out i have a 66mm inducer and a 56mm exducer cant seem to find any info on the as to what rear housing to buy anyone got any ideas?

been having a look around and the garret t31 housing i have on there atm soom to suit gt30/gt35 and its definetly a bigger than 60mm wheel (gt30) so im guessing it has to be a housing to suit gt35?
