the piping is bit complicated.. i've to picture 1 by 1.. u need to msn me... on
echocae@hotmail.com.. so i can give you more info.. the injector that i use is from EVO 6 injector they have the same injector as honda fit... the L15A motor can run 8psi safely.. but i run 11psi coz i change all the internal (forged piston, crankshaft ect2)... no online site that sell turbocharger.. u need to have connection in japan...
btw CVT on honda jazz is using CHAIN BELT (can handle 250 NM) and it has clutch so u can upgrade the clutch..
