I have searched, but my question is too specific I believe. A little background... 90, auto SC, 65k motor with the following mods: 76mm maf,75mm TB,2.125" down pipes no cats into 2.5" magna flow X res/muffler, into true dual 2.5 pipes with magna flow mufflers. 5% SC pulley 5% jackshaft pulley. Raised top,(I know, but on looks alone it should flow better ) IC fan. Have a conservative chip from Dave. I am getting ready to install a ported late model blower, MP inlet, 42lb injectors, 255 fuel pump, and a front mount IC. I am doing a same side front mount through the hole where factory cooler was. My question is, should I do 2.75" custom tubing or just use factory tubing from IC? What would this combo benefit from? I really have no plans on future performance upgrades. redid brakes and suspension alread. Thanks.
