Car Forum / Volvo Cars / June 2007Turbo Inferior to Non Turbo??
I've heard that a turbo engine will wear itself out before a non turbo engine. I've heard that it's better to downgrade to an older non turbo than keep a newer turbo because it will last longer. I've heard I should sell my car before things get really bad. My car is a '90 and started to accumulate some problems. But will selling it and buying the non turbo version (give or take a year or two) guarantee me more years of dependable transportation? > I've heard that a turbo engine will wear itself out before a non turbo > engine.

Well a turbo engine puts out more power than the same engine without a turbo so it's a given that it'll wear out a bit faster. The thing is, Volvo engines are legendary for being extremely durable, and with decent maintenance the engine will normally outlast the rest of the car, turbo or not. The turbo engines require a bit more stringent maintenance but the extra power is WELL worth it IMO. I can't speak for the condition of your car, but mine is currently a bit over 283,000 miles, still running great with the original turbocharger. If your car has been reasonably well taken care of I suggest taking care of the little problems before they accumulate to the point that the car is a beater with so many problems it's not cost effective to repair. If you sell it and get a different car, you're just as likely to encounter the same problems under the same conditions. As these things get older, it becomes all about how well they were taken care of. I once saw a very tired 740 Turbo in a salvage auction with something like 738,000 miles on it, the shift lever on the automatic transmission was worn down from hand contact and the interior was in tatters but it said it still ran. >> I've heard that a turbo engine will wear itself out before a non turbo >> engine.

While all this is true, the high-pressure turbo found on some 740s has a propensity to dump all of the engine oil down the exhaust if the seals get worn. I'm assured the low-pressure turbos are bulletproof, however. >>> I've heard that a turbo engine will wear itself out before a non turbo >>> engine.

I'm assured the low-pressure turbos are bulletproof, however. All 740 and 940 Turbo cars have a high pressure turbo, the LPT didn't appear until the 850 series IIRC. From experience, the Mitsubishi turbos used on some of the 700 and 900 cars do seem to hold up a little better than the Garrett turbos, but either one will last a long time if run on synthetic oil changed on schedule. >>>> I've heard that a turbo engine will wear itself out before a non turbo >>>> engine.

No, certainly in europe the all the 700's were 2.3TI HPT's with 185 and latterly 190 bhp. When the 900 came along, there were the following engines: (all 8 valve red blocks) 2.0t 135bhp 2.3t 155bhp 2.0T 165bhp 2.3T 190bhp The 2.3 16valve was available for a short time in the 940 SE with I think 160bhp, 4 sp+od manual box, but didnt last long, as it was considered way too short on torque for the typical 900 owner. (then volvo did the 2.0 20v in the earlier 850 which was the same!!) Tim.. > No, certainly in europe the all the 700's were 2.3TI HPT's with 185 and > latterly 190 bhp.

Interesting, in North America all 700 and 900 turbo cars had the same engine, B230FT rated at 160HP. 700 was available with a manual transmission, but all 900 series cars are automatic. >>>> I've heard that a turbo engine will wear itself out before a non turbo >>>> engine.

Not in Europe. We run two 740 turbos both are sweet .When some fool tries to jam you up the back of a parked car or pass and run you off a narrowing lane theres nothing like the turbo for safety .I bought the turbos for safety not speed .Any jap car can go fast but when you have a kangaroo jump out in front of you at 110 klm an hour its nice to have the handling and safety of the turbo 740. >>>> I've heard that a turbo engine will wear itself out before a non turbo >>>> engine.

I'm assured the low-pressure turbos are bulletproof, however. I thought that was what was happening to my '85 with about 220K miles at the time. What was actually happening was that the crankcase ventilation was getting restricted and the crankcase pressure was forcing the oil to back up in the return pipe until it spilled over into the exhaust. Cleaning all the ventilation parts - even the giant hoses - fixed it. After 240K miles the original turbo is still rolling along. Mike |
