Hello every one im planning on getting the greddy Turbo kit but i want to know how to reach higher psi on the turbo . I know a lot about rotary but im not the best with turbo. so if u guys can tell me how to help the psi go higher couse i seen a Rx8 with 4 psi and it was running better than stock but wasnt as good as i expected . im looking to hit 6 psi so if any one can help out thanks.

 

you will peak around 6 psi on the stock greddy turbo but only for a few seconds, most boost hangs around 4ish to 5ish. adjust the wastegate acatator screw and you can up it to around seven i have heard. after that boost controller but not over 9 psi without upgraded injectors

 

7.5 psi on a stock Greddy kit (tuned), going to 8 psi., drops of to about 6 at high revs.
