Been offered a T3 Turbo which as the following spec:

.42 Compressor Side
.48 Exhaust Side
360 Degree Thrust Bearing,

I believe it's from a cosworth, would this fit a Escort for a Zetec Turbo build and Would this flow the same as a stage 3 Erst T3?

Thanks

yea essentially a 4x4 cosworth t3. be good on a zetec turbo with quick spool up. what size is the compressor wheel?

HaggisTurbo

Standard to my knowledge mate.

You reckon this would flow for 300 ish bhp?

mgtkr1

yea should just about do 300bhp on a zetec.

HaggisTurbo

Would it be running at its limit on 300 though or a little extra room? Also would it bolt onto the RST Manifold or am I going to have so swap some parts over?

mgtkr1

id think it would be close to its limit but the spool up time will be as good as you could hope for with a t series turbo. it will bolt onto a rst manifo I have the same turbo on a 1600 and its not really laggy. on a 2.0 it will be spot on

Do you have a picture of the compressor side opening?
You will need to know what size the compressor is - 45, 50, 55, or 60 trim.
One needs to measure the compressor inducer size.

You have the turbine size of .48, good for 300 hp (maybe more in some cases.)
The compressor side will tell you the maximum HP capable.
One could have a 45 trim compressor with the .48 housing. This would be laggy and maybe support 230 hp.

Canada,

These are the only two pics I have this one is 2wd with 42/48 and a 360 thrust bearing



I also have the chance at a stage 3 t3 from a 4x4 Cossie


Man this is complicated ahhaha

looks like a 4x4 turbo

How can you tell that? lol Could have any size comp wheel in that 42 AR housing!
Exactly.
It does indeed, the two actuator bracket bolt holes in the comp housing give it away.... .48/60

HaggisTurbo

Here are the rest of the pictures of it,

Guy reckons it came off a 2wd is this pretty definite a 4x4 one?

Hope it is would be ideal!

2WD doesn't have actuator bolt holes in the comp housing.... but that's not to say it wasn't fitted to one.

HaggisTurbo

Ahh nightmare lol. The 4x4 one better specc'd I take it?

Guy also mentioned it has had a 360 thrust bearing fitted.

Does this make it a stage 2 4x4?

Karlos G

iTrader: (4)

Will flow a little more BHP yes, the 2wd has a smaller comp wheel (50 trim IIRC, could be 55).
It just means it will last longer, stage 1 you might say as it won't actually produce any more power than a standard one.

HaggisTurbo

Thanks Karlos, Is a standard 4x4 T3 the same as a Stage 3 RST One then?

HaggisTurbo

The guy has done some measurements for me. Does this clear up what it is?compressor measures 5.5" with a 2.5" intake and a 2" out to intercooler

Karlos G

iTrader: (4)

No, it's close but the 4x4 has a better flowing exhaust housing (both .48 though) and a larger compressor wheel.
lol No, that's the dimensions of the housing.

Part number is TB0384,

Think Im going to buy it if it makes similar power to a stage 3 t3 erst turbo
