T3 turbo with a cosworth 0.48 housing???
Turbo Mini Forums

Sorry guys just wondered if i could pick your brains. I have been offered a Re-manufactured garrett t3 turbo - -31 actuator - 360 degree bearing - 0.48 cosworth housing.

My question is will this be ok on my 1293 setup?, i do know that its common to use the 0.36 housing i think too reduce the lag but i have no idea if this will work or how its works even.

Any advice would be great.

thanks again.

thats going to be quite laggy, might be good for big power but might not com on bost properly till 5 k....

the std metro housing was .25 iirc, but this ends up replaced with the RS turbo one as the metty one is NLA.

worth a shot though if its cheap, as long as you report back!

Thats what I thought. worst case, could I just buy a rs turbo housing and fit that?.

I ran a T3 with the .48 housing and it was fine with mapable ignition, made good power too.

If something is worth doing, it's worth doing half of.

I used one a couple of years back. It was awesome at the brunters day but a pita to get off the line.

So in all it would be reali good top end but very laggy and not great down low?.
is it ok just to change the housing to the escort one if needs be or does it have to be re-ballanced etc?

Wheel would need changing too so would want balancing.

right ok ta. might be better off leaving it to turbo techniks then.

if its the same wheel as a metro turbo ,then the housing would swap ,no problem ,no dissasembly of the wheels would take place .

you need to find out the turbine wheel size .

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

T3 is the turbine size, you dont mention what compressor is fitted to it.

Mine was a 4x4 Cossie compressor and a 0.36 turbine housing and it was pretty laggy. So I'd say a 0.48 would be horrific if using the same compressor

But it did pull strongly from 5-7500rpm. Didnt really start making boost until 4k though and full boost ( was running 1.5 bar ) by around 5000rpm

Better fuelling and mapped ignition would probably help that though. Mine was 18 years ago and very crudely done

speed didn't kill me, but taxation probably will

to add, just seen the egay link.

It would have a smaller compressor than the Cossie, but larger than a metro
But it certainly does not have a Cosworth turbine housing on it. The Cosworth housing is unique to the Cosworth fitment. And that is still RS Turbo.

That's not to say it isnt a 0.48, but it is certainly not Cosworth 0.48

So who reckons I should gamble on it if its cheap

Give it a go!

It's already at £82 and £15 postage. That's almost £100.

It certainly isnt cheap for such an old unit.

How much do the modern GT stuff go for ?

Is it simple enough to change over to a different turbo?.
