Series 6-8 Rx7 FD3S 600HP Kit

  Turblown Engineering has developed this 550 to 650rwhp turbo system package for your 93-2002 FD3S Rx7. This setup has been developed from over 18 years experience with turbocharged rotaries. These turbo systems are not only dyno tested, but have years of track testing behind them.  First and foremost one has to choose whether you want an IWG( internal wastegate) or EWG( external wastegate) turbo system. The iwg system is much quieter as the waste-gate discharges into the downpipe, where as the external wastegate is very loud once full boost pressure is reached. The IWG system is much more reliable in terms of component maintenance, and simpler to install. The IWG also has the best transient response, and the lowest boost threshold. The EWG is better at controlling lower boost pressures, makes more peak RPM power, and ultimately more power in general( bigger turbo selection available with SXE turbos). If you still need more help choosing between IWG & EWG; read more here. For
