Turbo Time for the RX3

Turbo Time for the RX3
It's getting close to running with the turbo installed this time. Got injectors installed, I chose injector dynamics 1000cc for the secondaries. I'll upgrade the primaries when I port the motor. Got all my fittings for the turbo oil feed and drain. Got intercooler supply pipe fabbed. Got most of the exhaust routed yesterday. Exhaust uses 3" 14GA 409SS tubing, 304SS V-bands and RB universal mufflers. Interesting note on the mufflers they are directional, but don't say so. There is a unperforated length on the inlet side of the main muffler and presilencer. I believe this is intended to provide anti reversion and bolster low end torque.
To do today:
* Route exhaust to main muffler.
* Fab 2nd intercooler pipe.

The motor is a stock Cosmo 13B-RE motor. I figure it should make about 300whp on 10psi. Long term goal is about 400whp.
Bends are mandrel 45, 90, and 180s chopped and welded together. Bends are from columbia mandrel bending.

That is so cool that you knew it was from a Lycoming. Awesome turbo on my bridgeport. I expect more of the same with this motor. I changed the center housing for a water cooled one after it failed my rear main bearing due to low oil pressure. Factory center housing had too much flow for oil cooling for my old 17mm mazda pump too keep up. I was warned, but I did not appreciate the urgency of the issue.

Another reason I picked this cooler was that the inlet and outlet orientation would force flow to be distributed across the core more evenly than if it fed from the sides. A more ideal setup would have been bottom feed/ top exit, but I couldn't fit that style cooler very easily.

Here's some pics of my turbo manifold. I upgraded my wastegate to a 46mm Tial. I had to increase the size of the wastegate piping on the manifold. I used 1.5" SCH10 304SS pipe. The main runners are 2" SCH40 304SS pipe.

Thanks! The car has a Microtech LT8 with TII coils. Lots to tune. I put a 6 psi spring in the wategate to get me started. Trying to lean towards the side of caution. May be about 2 weeks before I can get back to the car.
