using 4agze someone offer me to turbo abot 5k.including s.steel intercooler piping,double layer radiator,levin intake( coz sc intake can`t use ),rb20 turbine,custom manifold,intercooler vr4,extra injector,can up hp till 190hp.so amacam ok ka?..
RB20 turbo is small no worry. if can get RB25 is much better. spool around 3500rpm on 4AGE good for street/track to run under 1bar boost. 4ag is a high rev engine, rb20 turbo is limit to run only 1bar boost to 7500rpm. it pump alot hot air if run over 1bar. hot air = knocking = blew engine. :lol: :lol: :lol:Originally posted by Raymond_Hu@Mar 1 2005, 15:49
just curious, can your 4agze 1.6 able to push a turbine from rb20 2.0 to run?? or may be when the turbo is running, it's already almost the red line zone already?

, would like to enquire the cheapest replacement for the stock turbo
