No real need. The 3 studs for the down pipe are spaced with the clear intention of having 3" tube brought right to the mating surface...
On the stock exhaust its necked DOWN to 2. whatever inches from the initial 3".

Remember even 390 hp Escorts used the exact same part number as any old Volvo T3 turbine wheel...(granted they did a .63 a/r but that's knowing they'd be using closer ratio box so once spooled, less rpm drop so no need to pull from lower rpm, and also they used fairly mean anti-lag..)

John, do you have any flanges that would work with a 3" flared pipe? I dont want to have to draw one up and get it water jetted.

Cheers John, had a feeling that'd be the case - seeing an unmodified TB0384 on an unmolested Sierra I don't think porting may be necessary. A friend of mine is using a Sierra Cossie loom and anti-lag system on his 240 soon.... Something for you to ponder over.

My Cossie knowledge is average at best...

For the record, my turbo ended up being a weird amalgamation of bits.

.48 Cossie exhaust.
Ford SVO chra
0384 compressor housing.

I bought the turbo from RS classics, and it ended up being garbage.
I then found someone local who was going to have their brand new CHRA rebuilt with a t04 compressor, so I gave them the core chra I had here, and paid the difference for his new chra.

Put my housings on the ford chra and Im in business.

That looks sexy. I'm taking my turbo engine out of the 940 this weekend so project Cossie Fawkin Turbo will be a go-go soon. RS Classics are always good.. I have a chap local ish to me who breaks Cossie bits down in Gosport near Portsmouth so will be checking him out for a TB0384 soon.

Copper plated..Work fantastic..Available where ever VW aircooled stuff is sold.
M8x1.25 with 12 hex
M8x1,25 with 13 hex
M10x1.5 with 14 hex<----my fave for turbo flange to manifold so you get a box end on them
M10x1.5 with 15 hex

Of course we all drill and tap the manifold to M10 as a matter of course, don't we?

You think you can scare up a Cossie airbox for "non-bend-them-over" price from your local guy?
Gary seems to like a weeeeeeeeeeeeee bit more squids than they typically go for in a normal private sale...

VW aircooled exhaust nuts, possibly Bug Pack. $5 for 8, 18 months ago.
Edit: I see JVL beat me to it.... By about half an hour.

Not Gary Z no, another chap with two that he's just taken on to break for spares. I'll enquire and see what his prices are. I'm on a few Cosworth groups and they're fetching £150-300 most days.

Annoyingly most are coming with shafts that are buggered or have lots of play. I aim to get one rebuilt, new 360 beating, actuator, seals and all at Turbo Dynamics near me.

Is that Vince? in Daventry?

And wait! Airfilter box, I was asking..I've picked them up a while ago at 20-25 squids.

One thing to think of is grabbing a YB down pipe for harvesting the first section wif the conical seat and that big fat flange...and a waste gate actuator...(just snagged 2 today off your Flea bay)

Of course master! Already clamped her to the ole commie enco, milled and retapped the manifold to m10x whatever these imperialist bastards had in the shop. I swear I had to search 20 min for a sutable metric tap.

Ah, sorry! I'll see who has an airbox, see what his price is and get back to you.

For ****s and giggles, I disassembled the cossie turbo I got from the uk today. The turbine shaft was so worn, it looks like sand went through the turbo.

Why would you need, or want, to install either a compressor bypass valve or recirculation valve on a performance orientated engine build?

If you drive without a BOV you get this lovely turbo chatter... On the other hand the turbo doesn´t like it a lot and will get damaged if it is not fitted with a special shaft (maram, polygon). I drove without BOV for a while. Sound during gear change is phenomenal, from
time to time the AMM got mean --> lambda light on --> idle started to get crazy...
Installed a bailey DV26, problem solved.

After reading online I will just fit a Porsche Bosch CBV, with the brass diaphragm. Keep the turbo spinning...
