Got a series of issues re. my car's idling and response. The zero-load-idling (no lights no air con) has always been around 900 rpm but drops to 500rpm when headlights are on, which required a little bit more...
im looking for a garret turbo which build boost from 2300rpm and hit max boot before 4000rpm. Any idea the the T25 or stock turbo from RD25DET able to achieve it?
