I own a Volvo 940 and the rebuild seems to take less of a toll on you then the W123's, it comes apart a little more effortlessly.. For awhile I was tempted to do some mischief with the Turbocahrger and cam on the Engine, but then common sense hit and I left them alone, since I am a Diesel Die Hard also, plus the fact that Gas is 2.10 a gallon now...

IPS sold a whole mess of parts to the HP/Turbo Upgrade, I bought them and then returned them one week later--I guess thats all due to experience--Volvo designed that car that way for a reason, and thats why I left it alone~~~
