How you going adam . If your only running 19psi on that turbo you will probably find you will be over 600 then at 24 + psi . It's hard to go into engine detail as most things have been done. Really just has Pauter rods , 87mm Arias Pistons , HKS metal head Gasket , HKS 272 272 10.25mm lift cams,hks valve springs , Jun oil pump , ported head , HKS valve guides , Tomei Cam studs , HKS Cam Gears , Trust sump extension and the usual smaller things. As with fouling plugs it hasnt as of yet but you do get a miss every now and then running that boost so i might gap the plugs down firther i think there gapped at .8mm atm. Still runs stock coils though.
