Have a question on a gtx 3071 with a .82 turbine housing on a 900 cat upped to a 995 with Linermans porting setup for turbos. Will a .82 or .63ar turbine housing have more air flow at a idle. Will the .63 be quicker to build boost to a point and the .82 be slower but build more boost. Have both housings and the tial waistegate with seperate outlet. Also going to buy 3076. Also the garrett turbos gtx will 5psi pump be good enough. Have a pulse oil pump coming also.
