When engine is being put back together, I'll see if the inlet manifold reversed, but still pointing upwards will clear the altinater, hence saving my air-con
I have a lot more room between the bonnet and the engine than the imprezas!
I have even thought of using spacers between the inlet manifold and the heads to step it up a bit and to get more penlum volume (which is supposed to be a good thing!)
I'd run the pipes over everything and either side of the rad to the big grill between the the headlights rather than going through the wings, and I'd rotate the compressor housing of the turbo so it's facing up for even shorter pipe work!
If all that worked out, The pipe work would be damn near 3M shorter (at best) the likes of Hybrid or autobhan88
I would very much like to see on a dyno run, a car come off throttle, and back on and the delay measured,
Then reverse the inlet manifold and re-run!
It has to make a difference,
I drove Micks 2.25 with a 20g and a front mount, and it was defo laggier than my forester when it had the 20g, saying that the forester is 2.5, but I thought it was a bit much, even at high revs!
