GA16 injectors + walbro 255Lp/h pump + fpr + t25 turbo will get u boosting happily @ 7psi - is a fun package.. 2.5" zorst would be fine for that setup..my 2c
thanks for the tip Pierce, but i don't do FB mate... i know that the standard for a lot of "micra enthusiasts" is POV-spec, and that this is a quality build with quality parts - i don't do my **** any other way. someone with sense will appreciate this package and snap it up
