Pulled my factory turbos today to do turbo seals and high pressure turbo had alot of shaft play.. I was told I needed to replace the turbos so I was wondering stock remans with aftermarket batmowheels or a single charger setup? Who sells the best single charger kit? That includes everything I'll need for a reasonable price. What's pros an cons of both? Thank you! Mods I currently have are 5", cold air, airdog lift pump, spartan tuner. Will the spartan work with single or no
