as some of you will know i have fitted a disco 200 tdi into my 90,at the mo with 205's fitted it struggles to top 70 & is reving to its limits at that,with 750's fitted it does just over 65 at a lower rev range but woint go any faster,
on start up it has a sharp diesel "crack" like a ford tranny DI engine & tonight i striped the front of the engine to check the timing & everything is bang on the mark,also changed the fuel intake banjo bolt for 1 with a slightly bigger internal size which made nearly no differance & also fitted a new lift pump,checked the boost & its doin 7 psi & havnt tampered with the fuel injection pump yet,
any suggestions before i remove the injection pump to get it seen over by a specialist
