These studs are available for all 13B engines including the MSP-13B Rx-8 engine.

Torquing the\u003c\/span\u003e\u003cb\u003e\u003cspan\u003e \u003c\/span\u003estock bolts creates friction\u003c\/b\u003e\u003cspan\u003e at both the threads, and head of the bolt. This unnecessary friction promotes\u003c\/span\u003e\u003cb\u003e\u003cspan\u003e \u003c\/span\u003efalse torque\u003c\/b\u003e\u003cspan\u003e readings and the result is reduced and\u003c\/span\u003e\u003cb\u003e\u003cspan\u003e \u003c\/span\u003euneven clamping force\u003c\/b\u003e\u003cspan\u003e. Instead of \u003c\/span\u003e\u003cb\u003etwisting a bolt\u003c\/b\u003e\u003cspan\u003e to achieve a desired torque reading, \u003c\/span\u003e\u003cb\u003estuds are stretched\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003e\u003cspan\u003ein a static position.

The \u003c\/span\u003e\u003cb\u003eOEM bolt material stretches \u003c\/b\u003e\u003cspan\u003eunder high boost and in turn, reduces clamping force. An engine using the OEM bolts will expand \u003c\/span\u003e\u003cb\u003eseveral thousands\u003c\/b\u003e\u003cspan\u003e, as measured with a strain gauge on an engine dyno. This expansion can damage to the engine's internals. Common harmonic, and resonance issues are reduced due to the superior material used in the stud manufacturing.

These studs are \u003cb\u003eprecision ground\u003c\/b\u003e from aircraft quality forged steel. The \u003cb\u003ethreads are hot rolled\u003c\/b\u003e, not just cut with a die or a lathe.

One can torque these much higher than the OEM bolts without any breakage( maximum of 77 ft lbs for studs, please be aware front iron might break near this limit).

Lubricate the front iron threads, and use a silicone sealant near the OEM sealing washer threads(OEM sealing washers not supplied). If using lubricant on the OEM sealing washers, use brake clean and wipe the studs clean once the sealing washers are installed. Let the sealant on nuts setup overnight and pressure test engine coolant system to confirm proper adhesion of silicone sealant. Pineapple Racing Pressure tester or equivalent is recommend to use before engine installation.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe Black Mamba Racing Beetle runs the Turblown 13B stud kit with zero other modifications.
