Modified turbo exhaust pic

[Steptoe]

if this w9rks should see an abortion of a modification someone made to this EA82 T crossover pipe

Looks like someone thought they needed to open it up for better flow but I think it may be why this engine won't walk up the same hills in 5th my other EA82T used to.

Engine coming g out to swap in a better more factory pipe of the smaller 36 mm hole under turbo, think same as this abortion. Also have 42 mm one but it sort of makes the engine get away from me, spin out too fast and lose the torque I want

The engine came out of a car that came out of a Subaru rally driver runs, so thought it may have been one of his go faster mods. Now think not

Not sure what you're trying to communicate, but my EA-turbos love having larger exhausts and manifolds.  They lose some low end oomf, but they're happier at almost every RPM.

I have two different 'size' exhaust cross over turbo up pipes. One with 36mm hole directly below the turbo which gives a nice low down torquey response, and the 42mm hole just takes me by surprise as to how quick and easily it will rev out to 6500 rpm but lacks the low down torque I like for my purposes ( not trying to blow everyone else off at the lights)

 

This pipe came from a donor EA82 wagon that  inherited Vortex running gear minus disc rear. It looks like someone has tried to open it up below turbo side head to give it who knows what, but the pipe continuing on to the turbo is still the same scrawny thing.

 

I have a certain long hill to go up almost daily and my 36mm piped EA82Ts will walk up in 5th gear, light throttle, no labouring whereas this engine, with this pipe loses it and needs a shift down a gear , or two - then sort of blows my up the hill in its 80 kph speed limit zone. My NA Mongrel could do this as well in any top 3 gears

I wonder if one engine is more worn out than the other, as I wouldn't expect an exhaust header (and a fairly stock looking one at that) to require a double down shift to climb a hill.

More likely you're looking at a cracked pipe that a previous owner tried to repair...

An autopsy will be interesting on the pipe. Current engine supposed to be low km import but must be getting harder to believe after 30 years. Even when they were 20 years old was hard to believe and still cheaper to rebuild one back then than buy unknown import. Had one with orange sealant and new head gasket. Never in now 35 years seen a true import come in so touched and it revealed 50% compression loss in one pot but was still smoothest strongest EA82T I have driven ...no one would detect that blow by ...

Either way a butcher was at work there. Probably had to weld it back on several times due to the pressure and heat from the turbo extractors/headers.
