Wot shape should the exhaust housing be because mine looks different to my standard 1 tell me if im being stupid but it just looks different like an oval shape??

 

should be the same shape, just a bit bigger.
take a pic put it up and we can see exactly what you mean.

 

Cant take photos coz i dnt no how to upload from my phone you no the bit that bolts to the exhaust manifold it should be rectangle shape my new turbo has an oval shape lump on the top and bottom of the rectangle do you get what i mean?

 

not understanding that.
take photos off phone and upload to photobucket.com
then use the img links it generates and post them on here.

 

Lol right ill try and put photos on tonite you know where the turbo bolts to the exhaust manifold its a rectangular shape my new turbo instead of being rectangle it has half oval lumps on the top and bottom but straight on the sides of the bit that bolts to the exshaust manifold

 

that makes sence, its normal sceen loads like that .

 

Ok then so it wont make a differnce and will work the same one more thing how can i get a fan inbetween my rad and intercooler without completely chopping my bumper coz its running a bit hot cheers

 

Fans should only come on when your not moving (stuck in traffic, etc..) if your running hot when going along then moving the fan to there will not help.... you have other problems, maybe time for a new rad, or just a good flush out.

 

Well i no my ally rad is leaking and i think i might have to much antifreeze init coz it smells like its burning when it gets hot so iv ordered a standard rad

 

sounds like its a .48 housing or has been rebuilt using a skimmed volo or saab housing etc.

 

Will a saab or volvo turbo still work and be ok??

 

i think i know what you mean now, the flange on th eturbo isn't rectangular as such, two curved sides, two straight.
cossie housings are like that, don't panic.

 

So will the cossie one still work the same?? Sorry if i sound thick iv never changed a turbo before and just want it to be right cheers

 

if its fitted and working it will work the same. It should also have some cast numbers on it that would be handy if you can read them.

 

Weird my stage 3 t3 has a t3 flange !!! Better internals tho 20 psi no probs

 

I havnt fitted it yet and there are numbers on the side of the flange im sure it has a 48 or somthing on it but im not certain wot would the numbers help for??

 

this tells you the size of the housing. Std is .36 the norm upgrade is .48 then .55 then .63 etc..

 

Is this the number u mean

not really a gd photo because its off my phone lol sorry

 

That is what i mean however its not normally there the casting marks. Where did the turbo come from. It could be a copy exhuast housing with the rest being genuine parts.

 

I bought it from someone on here its brand new will it be alright do u think??

 

could never say without taking it apart to see internals and thats a waste of time and money for a balance unless your really worried about what you have bought.

Looks fresh enough but thats easy to do.

 

Is there no other way i could tell its a stage 3 turbo

 

what is a stage 3 to start with. There is no deffinate of what is what. Who is to say its not a stage 5 by someones standards.

For example (and piss taking)

my stage 1 could be to clean all the parts and fit it back together.
stage 2 paint the compressor housing.
stage 3 sign my name on the exhaust housing.

lol.


Sell it to you as a stage 3 turbo and you are none the wiser. Thats why the Turbo market is full of crap and scrap turbo's. You can never be sure what you have unless you ask for what you want!

I always state exactly what i want inside and pay the supplier for each part seperatly then build it to that spec. I never quote stages or expect people to know one from the other.

The best thing to do is remove the compressor housing carefully without damaging the paper gasket and measure the size of the comp wheel. This will tell you which one has been used i.e 2wd or 4x4 or even std T3 ERST.

Then take pics of the comp housing as the 4x4 unit is easy to spot if its genuine. Most Turbo suppliers will machine out a std T3 ERST to the size they want. It works but causes the air temp to be higher due to the size of the housing being smaller to start with the it should be. Obviously large coolers make this less of a problem now days but the turbo is less efficiant.

Hope that explains a little from my experiance working for a turbo manufactor.

 

i thought all t3 comp housings the .42 were all the same size i bored standarded escort
to 4x4 comp wheels and look the same in side no difference at all may be wroung

 

If you look on the website or call the company from which the turbo came they will state exactly what spec each stage turbo they do is
If you dont know then ask the person your bought it from, as you say it's new.

Rule of thumb for RST T3's IME is...

Stock T3 .36 Turbine housing .42 Compressor
Stage 1 As above with 360 degree thrust bearing.
Stage 2 As above with a .55 Compressor.
Stage 3 As above with .48 Turbine housing.
