Tom Posted November 22, 2006 Share Posted November 22, 2006 If its had a rebuild you'll have all the RX8 internals so no future probs if its serviced properly warm up / cool down and don't forget to check the oil!! (check correct oil as RX8 uses different oil) Alot of the relaibilty issues with Rexs is myth as anyone who owns one will tell you, your main problem will be mpg !! My mate kirk has the bright orange one thats heavily mag featured (you took loads of pics at Boxhill meet of it) but that was early days for it, His Rex is a true stunner now !! 8 -12mpg is realistic mpg you'll get unfortunatley, The RX7 is a iconic car though !!! RX8 internals? are you sure? Quote Link to comment Share on other sites More sharing options...

blitz supra Posted November 22, 2006 Share Posted November 22, 2006 RX8 internals? are you sure? yep with the rotary, its one of the only engines you can fit new into old, They Use RX8 rotors / seals etc and the old RX7 probs are gone, Modern technology, Remember the RX8 is basically still the rx7 engine but with forced induction etc and renamed renisis, Unfortunatley its untuneable as Mazda have basically extracted everything already, so 231 is the limit although j spec is supposed to be 250bhp Forget the Turbos and Superchargers listed for RX8's in the US, its proven they blow up .. The missus is on her 2nd RX8 fantastic car is an understatment Quote Link to comment Share on other sites More sharing options...
Tom Posted November 22, 2006 Share Posted November 22, 2006 Thats strange as from searching on the web I havent seen that mentioned at all, and I'm rebuilding mine at the moment!lol I also thought rx8 engines had to be rebuilt anyway as they still have the same apex seal problem?(well wear and tear) Quote Link to comment Share on other sites More sharing options...
