Kms On A Turbo Engine?

Dunno where you heard that but it all depends on how well you look after it. Regular servicings and it should last as long as you want it to. As for thrashings, several motors have been pulled down after running ridiculous amounts of power and been within spec, almost like they came straight from the factory. There's no blanket rule that states turbo cars wont last as long at NA ones...

There is more stress on a turbo engine than a N/A. Like skylines for example, you will notice that allot of people sell their Skylines when they hit around 70k. Its because they either require their MAJOR service or they need a rebuild.

Being brought up in the N/A world this is what I have been taught about turbo engines.

To me the T is the ultimate car. Although I also once thought that the T would last as long as any N/A engine (partly due to its low boost, great engineering & tuning) I have been lead to believe that this engine will not last anywhere near as long as N/A performance engines such as the Ls1.

well the LS1's use oil from new so that's a good starting point

Remember also these engines are designed with turbos in mind along with particular boost figures.

You cant compare it to a NA motor that is converted to a forced induction motor (I know you aren't, just for example's sake) as it wasnt really designed for it and is likely to not last as long.

The difference between the two motors in this case is these are designed properly and run in that way. Going from the NA mentality to worrying about "these kinds" of motors being turboed isnt the issue really. They are generally designed with protection in mind.

Thanks for your response guys, It wont be long till im in a turbo of my own!!!!

A few facts and comparisons to ease your mind.

Many earlier Saabs and Volvos with more highly stressed turbo engines than ours will easily do 400 000km with appropriate servicing.

I've driven a Liberty RS with 240 000km (which I think run close to 13 psi stock) which drove like new.

Turbocharged truck engines are just as durable as non-turbocharged truck engines (I know diesel is a different kettle of fish but its worth considering)

Falcon base engines are designed to do many hundreds of thousands of Ks using LPG (up to a million even - as taxis) which provides a hotter combustion environment than petrol. We have a very strong base to work with.

and

if it does go boom at the end of the day a rebuild will cost less than $2000 with quality parts - you won't find a cheaper-to-fix modern performance engine.

I may be wrong but the forst thing to go on turbo engines is normally the turbo itself?? I know a few people with turbo cars (WRX, Evo, etc) who have replaced their factory turbo after about 100000kms.

Smaller turbo's = more rpm = more wear and tear.

Look at Volvo and Saab for durability of turbo engines. I know Saab did a 200,000k test some years ago, where they ran 2 or 3 Saab 9000 turbo's for 200,000k's non stop at an average speed of over 200 kph on a circuit, and all 3 cars came through with flying colours. The basically only stopped for fuel, service and driver change for 40 days (or thereabouts).

If you look after your turbo engine and change the oil regularly, it will last a long time.

Ford put a pretty good ball bearing, liquid cooled Garret GT35/40 in the XR6T which may give increased longevity. To get most Jap turbos into 12s you need a bigger turbo while Ford's GT35/40 is rated up to 700hp I believe. Therefore our turbos are good quality, are not highly strung or working to their full capacity.

[Paradoxx]

Nowhere NEAR their full capacity hehe

Hence the speculation of going for a smaller turbo on the next model T

[markxr6t]

Hmmm - just trying to imagine a smaller turbo that spools up even quicker???? Perhaps Ford didn't realise the monster they'd create.

All depends on how the ks were racked up. All freeway ks are fairly easy on the old girls. I've done over 130k without any issues
