what is the difference between t34 turbo with .48, .55 or .63 exhaust housing.what is the + points what the - points.
thanks

 

It is the size of the exhaust housing. bigger number=bigger size and that is more bhp you can get from it. But But the + of the smaller ones is less lag.

 

Pretty much as above, except the larger sizes tend to have more of a kick when they come in as well, owing to the fact they lose that much more not on boost power.

in very basic terms

.48 - very quick spool up, but normally runs out of steam at high RPM
.63 - not as quick spool up, but can still provide power at top end of RPM
.55 is in between the .48 & .63, the best of both worlds

i had t34.55 on my road car and was very happy with it

 

thanks guys.is there a number at the turbo where i can see witch it is?maybe some pictures?

 

the number is stamped on the inside of the exhaust housing where it bolts to the manifold

 

they dont always have a number stamped on them
i heard somebody say that if it wasn't stamped then it was a .55 but i dont know how true that is

 

I am also curious to know what exhaust housing I have on my Sierra Cosworth T34, is it possible to measure the outside diameter on the house to get this info? And if so, what figures should a .48 or .55 have?
I cant find this number on mine T34.

 

thanks,this helps me a lot.someone knows what housing the original escos have?

 

.63

 

nicethanks

I cant find this number on mine T34 and I am not planning to look inside the turbo for now.
One good member here told me it could be .48....

 

i do not know what the measurements are; can you see any numbers on the exhaust housing.

maybe if you post up some pictures of the turbo; i might be able to tell you what you have

 

Okay, here comes the picture, I hope you can see the size...

Hmmm I was not able to send it here, can I send it to you on e-mail or can you advice how it is done here?

 

you need to open a photobucket account and load them off there to here!if yours has nothing on it i would say it might be a .55

 

Standard escos has a .48 housing.

 

i thought big turbo/ early escos were t34.63?

 

use www.photobucket.com and copy the img tag and paste it in here

 

Not sure now then there was a receipt in my service history to supply and fit a .63 housing to my turbo so i just presumed that they had .48 housings as standard and this was an upgrade.

 

standard escos's defo do not come with a .63 standard

 

so what is it now?.48 or .63?someon knows where i can buy some good secondhand turbos from escos?

 

Well i thought they did

 

Mine has a .55 housing and no numbers

Anyone know the Ford finis code ( if indeed Ford still do them? ) for the crushable washers that sit either side of the banjo bolt that holds the metal water pipe onto the turbo?

 

paul at North Yorks RS Spares, his name on here is "rs500 registrar"

 

just use a cooper washer

 

I to thought escos had .63 housing?

 

i'm pretty sure they do; until proven otherwise that's what i'm sticking too!

 

Me too

 

My EsCos BT have oryginally T34 with .63 exhaust housing (number is inside, in the inlet) and have .60 turbine housing (number is inside of turbine outlet)

Hallo

yes, i'm sure early (large turbo) escort cossies came with t34.63

Thanks

 

im afraid they do pal

 

nice discussion,

can someone tell me who's selling the .55 housing ? I'm gutted because my T34 is to small (.48). Even with massive cam and very strong actuator it spikes at 25psi and collaps to 15-16 psi. I'm working with the french cosworth so dont shoot me. The engine was build by a friend from the UK and i finished it. i'll tought it had the .55 turbine...but its the 48.

if you are just after the exhaust housing most turbo places sell them

thx !

 

turbo technics are the only company that actually make the .55 housing!I doubt they will sell u just the housing,they will want to sell you just the turbo(they will probably say they dont have enough in stock!)you might be able to get a company someone like tony at turbo systems to supply you one via turbo technics,they are not cheap around £360 just for the housing!you might be better off trying to get a .63 as these are more common and usually alot cheaper

 

every escort i've ever stripped have eith er had a .55 or a .48 fitted if they were standard
i had 1 in that was around a year old, totaly standard and among other things it was getting a .63 fitted, which was quite noticably bigger than the standard 1
so i still stick with them being smaller than the .63 standard
i cant see them all having been changed(inc the 1 above) for smaller housings before i got to them
