Miata Turbo Forum - Boost cars, acquire cats.
It is crazy how the rpm jumps 700 rpm with flat shift. The clutch release and rpm climbs. The switch activates and 40ms the fuel shuts off. I assume the spark is cut off too. But the rpms still climb. Is boost driving the pistons to higher speed?

The flap hits so I clearanced it. The actuator doesn't have enough stroke but I'm keeping my options open. pun intended.

Rounded and enlarged. All the work had to be done through the inlet. I used a small right angle grinder and a good 3/8" round end bit. I only enlarged it about 2-3mm.

These turbos are already ported really well to direct the exhaust flow. But I see that ledge could be rounded off and get a little bigger on the diameter.

I welded on the oil return. I warped the crap out of the cover but it still bolts down flat.

I tapped extra holes around the perimeter to help pry the oil pan off next time.
