Hello Califorum I got the original Calibra brochure from August 1990. I ran a little bit and there were only the 115hp and 150hp engines. But what misleads me is the consumption of the 2 engines. The 16V is everywhere more economical Can’t imagine. 115hp 150hp 11.1 10.4 city 6.1 5.7 90kmh 7.5 7.2 120kmh consumption 10sec 8.5sec from 0100kmh 205kmh 223kmh final speed Is the stronger engine then from house more economical from consumption, although me Your performance Repair costs and maintenance/warning can’t be afforded either, right?! Unfortunately, I don’t have any of the 136hp engine. Which engine would choose “IHR” if it was worth fuel costs, repairs, maintenance of the car/engine, long life. Driving performance would be completely secondary. vg
