Series 4-5 Rx7 FC3S 500HP Kit

 Turblown Engineering has developed this 450 to 550rwhp turbo system package for your 1987-1991 FC3S 13BT Rx7. This setup has been developed from over 20 years experience with turbocharged rotaries. These turbo systems are not only dyno tested, but have years of track testing behind them. 

For this particular 500HP package comes with your choice of EFR 8374 EWG, or 8376 SXE EWG from borgwarner.

380rwhp @  15 psi on pump gas( with quiet exhaust, and stock ports, stock intake)

420rwhp @ 16 psi on pump gas full 3" off road exhaust street-port ( stock intake)

440rwhp @ 17 psi on E85  3" off road exhaust street-port

500rwhp @ 19psi on E85 with full 3" exhaust, street-port

550rwhp @ 26 psi on E85 Bridgeport, 4" exhaust ( max power level) 

Main difference between kits is simply the SXE is a journal bearing, oil cooled only turbocharger, which cost less and does not include a built in BOV( EFR only). There is a 600 rpm difference in boost response between the two turbochargers, the EFR being the faster unit( BB/ gamm-ti turbine wheel). 

Adding the optional turblown intake system nets 30-40+rwhp.
