Turbosmart's Internal Wastegate Actuators are quickly becoming one of the hottest boost-control products on the market. And for those wanting to run big boost pressure, without the hassle of fitting custom exhaust manifolds and external wastegates, Turbosmart introduces the IWGHP, High Pressure Internal Wastegate Actuator. The IWGHP range provides better turbo response and greater sensitivity when managing boost than a stock actuator, with the added bonus of being capable of handling high boost pressures. Only 28mm longer than the standard IWG75 these wastegates are ideal for high boost turbo diesel and racing applications. Available with 35PSI springs as standard (10psi to 40 psi options available), for the extra hard core. Yep, that's 40PSI without even having to change your manifold.
