like mat said i dont think they will change the design much. i think they will just imporove ways of making the design more efficient such as using nitrous to spool it etc.2JZBoost said:I'm sorry, I do understand how turbo's work, I was just wondering "New" ideas in turbo's like when ball bearing turbos came out. Are there any that have new oil cooling systems, or new impeller designs that let them spool faster while increasing heat dispertion...
