is there somebody know why there's no boost after the engine complete warmed up? (for 93 RX7)

 

I'm usually the type to fix problems myself, but with something like that just take it to the dealership and have them diagnose it. Its alot less of a headach. My turbos had no boost after 4,500 rpm and the dealership found out it was a check ball and a crispy old broken vacuum line. After that I had alot fun with it.

Pretty funny--a guy with 2 posts asks a question, a dude with 4 posts tells a story, and old man Mahjik with 48 million posts tosses him a link that will solve all his problems
