What year/model 700 series Volvo came with the 16Valve double overhead cam turbo engine with intercooler? I'm beginning to wonder if I've just about worn my '93 240 out. & want to begin looking for a newer wagon but with a more robust, READ high horsepower potential. There are many used volvo opportunities at favorable prices since no one here to fix Volvos their simply falling by the wayside. I want to snatch up the correct year/engined auto when I see one.I'm not fond of the front drivers like the 5 cylinder 20 valve models. Is there a source of information on how the models transformed from one year into the next with a summary stating thus the 19XX with the REDMOTOR & TURBO INTERCOOLER HAS THE POTENTIAL TO PRODUCE 500 SURVEABLE hp?
