I have had my SR in my '91 HB for about a year now and the realiability of the engine has been great even running elevated boost levals as a daily driver. It's the car that I have to fix most i.e. tie rods, t/c rods, suspension, brakes etc. The extra power
will cause you to have to replace this stuff and also reliability depends on the amount of HP you plan to run...the mo' HP the mo' problems <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/music.gif" border="0" valign="absmiddle" alt=':music:'> Levels between 200hp and 275hp should be pretty reliable but anything over 300hp you can count on plenty of 240 downtime
