As Costina said, it needs to be heated up and cooled down correctly, I usually throw whatever I've welded into a pile of sand as it keeps the temperature decline nice and steady.
Yes mate i know but your manifold is a single scroll which will have a bigger T4 flange welded on, I'd of thought you'd be better off with a proper single scroll housing on the Borg
The t3 is single scroll Ford bean counters decided the t3 would do the job as it was cheap and reliable and it did it very well .
The manifold should work well if Jay bodges it properly to take the BW

Crazy they didn't put a twin on it standard, is it divided in the elbow that sits between manifold and turbo?
Were there proper twin scroll (as in twin volute) turbos around when cossie was launched then?
My car goes up to Nortech next week for a custom twin scroll manifold, 3.5" down pipe and exhaust system. Also doing a custom stainless oil drain. I don`t expect to see much change from 1.5K ish. There was no other way of doing it though, add to that the transport there and back.....beans on toast for a while
I`ve also heard the 2wd manifold makes the BW turbos touch the head? I suppose you could bodge it with how the flange is welded on.
Like i said IF someone invested the time and money for a special cast trouser section for this range of turbo's it would make it more cost effective for us mere mortals.

Personally i think it will work well.
Didn't martin make a spacer for the trouser section to lift it up for a gt30 to fit? Is the trouser divided aswell? If not it might be worth getting a custom one made

Yeah trouser is divided.
Spacer and a suitable flange sorted.
Twin scroll turbo's are nothing new been around for many years the most famous one was the Toyota CT-26 twin entry on the Toyota celica GT4 in the early 90's known as twin entry
Well ahead of its time the YB engine and ecu. I still can't get my head around how tuneable they are with so little, to think that back in the 80's and 90's you could tune them to 400bhp is astonishing.
I came from Liking imprezas so the Yb is state of the art in comparison.
To top it all off its the best looking engine on the planet.
The twin scroll manifold probably stems from cosworths develoment of the F1 turbo engines of that era her's a video of Rimmer explaining the bmw m10 turbo 1500cc engine running a twin scroll turbo at upto 1500 bhp
The guy at RSR engineering that rebuilt my 911 engine worked on a few f1 and lemans engines in the turbo era.he said they used to have massive budget to run the engines from 1500 bhp and upwards, often melting them at close to 1800 to just see what they could do.

People can melt their cosworths with a lot less power and budget than that

Twin scrolling the turbine housing will rejuice it's area radius, A/R
Of coarse that's why a bigger a/r is needed for the same flow in twin scroll, surely the open scroll t3 didn't utilise the twin scroll manifold as both seperate pulses are just pumping into one big hole?
