Ebay twin turbo setup Checklist...Turbo a SBM for under $1000? :)

Hey caco 2120
I like your project , I have done something similar with an EBay Turbo ,
I went large single in mine
New Aftermarket GT42 Turbo Charger Oil Cooled T4 Inlet 6 Bolt Outlet | eBay
With China turbo's what I have found is some seam to be reasonable copies, and some are copies of copies .....
So I am at 10psi on an old poly , I have no intercooler , ( Carb is intercooler) I have a good boost retard and I make sure it's rich at 10psi , and it's living :) I have China 60mm wastegate , GT 42 , and blow off valve , most of the little bits and pieces ( fittings ) are EBay too..
Good luck cheers Peter
