With our new block, a few small things had to be fabricated, like a fitting for the oil pressure sender (as seen here), which we couldn't get through the dealer that week.

Toyota Supra Mkiv Sound Performance Aluminum Pipe
Since our new compressor housing didn't come with the 90-degree aluminum bend that Sound Performance usually uses on its Supras, we decided to use a 90-degree silicone bend instead. House of Power ended up doing a one-time fabrication of the pressure pipe to the intercooler pipe, meaning we can now swap in any similarly sized turbo without necessitating that 90-degree elbow. in any similarly sized turbo without necessitating that 90-degree elbow.

Toyota Supra Mkiv Turbonetics Blow Off Valve
Initial testing revealed a fluttering sound coming from the Turbonetics blow-off valve, which was obviously inadequately small (rated at 500bhp) and leaking boost no matter how tight we set the spring. We tried Turbonetics' Godzilla unit with a 38mm flange opening that's 27 percent larger in diameter. Figuring out Pr2 gives us an exact 60 percent improvement in flow, or 800 bhp, which Turbonetics also rates it at. The Godzilla blow-off valve vents at the front before the intercooler. We were pleased to see our AEM logs revealed a 300 to 400 rpm improvement in boost response during road testing. Thanks go to Imagine Auto for welding the Godzilla flange for us.
