Old Rajay Turbo Kit 240d
your difficulties with spoolup might be somewhat alleviated by
eliminating the rollercoaster of twists and turns and changing diameters
of piping you have supplying air to your turbo intake. going with a large diameter as straight as possible pipe from your air filter to turbo would be of help. also if you are looking to fab a new (straight) cone to bolt to your turbo intake consider integrating some honeycomb for airflow straightening which will help make your outdated turbo a bit more efficient. i have pulled some pretty thick pieces off of lexus's maf/map boxes.
didnt know toyotas were good for things other than seat donations? life is full of surprises!
also consider boxing the area behind the headlight where your air filter is or better yet if you really want to feed your snail remove the louvers that are located between your foglight and radiator and fab a box to pick up your intake air there. it is a bit closer to the stagnation point and will yield more pressure yet!
removing the soot injection from my california 240d was akin to adding a turbo
make sure your crankcase ventilation is top notch!
