Spool Performance is proud to introduce their one-of-a-kind top mount turbo kit featuring a 5-axis machined billet exhaust manifold for your MK5 MKV A90 Toyota Supra.
This process has allowed them to create a unique manifold that features ultra short runners providing maximum heat energy retention up-to the turbine while avoiding common issues with cast manifolds like cracking and increased weight.
The 5-axis manufacturing process has also allowed Spool Performance to create an extremely efficient flow by equalizing wastegate port design allowing for excellent boost control with a single 45mm wastegate. The result is a fast spooling and lightweight manifold that delivers almost nonexistent levels of backpressure and is easy to install.
The modular nature of the manifold design allows us to offer these kits with a wide variety of turbo options. The kit can be configured with a Spool IFX water cooled ceramic ball bearing or Precision air cooled turbo.
This Spool Performance kit is designed to be a true plug and play solution.
Included with the kit are AN fittings for oil feed and drain, water feed and drain (Spool IFX Turbos), and a water bypass (Precision Turbos and others). Spool Performance also offers an optional catch can solution that is a true plug and play solution. A corrosion resistant 304 stainless steel mandrel bent downpipe and dump tube are also included for your MK5 MKV A90 Toyota Supra.
They also offer the turbo compressor cover in a color of your choice (default red) and cerakote thermal coating for the hot parts.

The Manifold:
After countless hours engineering their manifold design, Spool Performance was able to create an extremely efficient twin-scroll flow channel in the 5-axis machined wastegate flow ports that allows for excellent boost control.
Spool Performance's manifold is milled out of high-strength steel alloy billet blocks that have minimal heat expansion. Being able to mill the flow paths into the block has allowed them to use short but smooth flow channels up to the turbine housing. This retains maximum heat energy and reduces turbulent flow energy losses in the system allowing for a faster spool and ultra-low backpressures at higher engine speeds.
The modular design has also allowed Spool Performance to create variations quickly to allow for a variety of turbocharger options.
Wastegate:
The wastegate flow ports are one of the most overlooked but critical components of a good manifold design. Through CFD optimization, Spool Performance was able to design a wastegate port with equalized flow between the turbine runners and the wastegate ports minimizing turbulence when the wastegate is closed.
Their system also uses a single 45mm wastegate reducing the amount of parts in the kit.
