I went today to a workshop, and there, they told me the 300TD ( 1992 ) didn't fit on the 190 2.5 TD . Only on the 2.3 16v car 'cause it's 6 cm's longer than the 2.5TD. Is it true? or can i fit the 300TD in the 2.5TD chassis? For the wheels. I'm confused. I don't know if i better put a 16" wheel or a 17" wheel with the 2.5 TD engine or the 3.0 TD. The Performances with th 17" are going to be more low than with 16" ? or the car takes the 17" wheels good? Please help me <img src="http://www.mbclub.co.uk/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=''> Another question. For the 2.5TD and 3.0TD engines. What can i do to get more performance. Turbo pressure and air filter? just that?
