So I love Turbo's and own a 12' Chevy Cruze Turbo. So far all I have done is K&N short ram intake, but come spring I am going to install boost gauge/oil pressure gauge in a pillar pod + I have a rear diffuser that I am going to put on with dual pipes and a muffler delete. I am pretty mechanically inclined, I am just not sure what all the Turbo Formulas are to figure out size and trim etc. I really want to build a small street cruiser (motorcycle) something between a 400cc and 650cc. I have no idea where to start and was curious if anyone on here has done a step by step build on here. If so can someone kindly point me in the right direction. I am looking to do this project as cheap as possible, my goal is to make a 400-650cc bike have the performance of a 900cc+ Thanks
