The SRT and Trackhawk would like a word with you
Mopar to replace the current v-8 with a inline 6 twin turbo? say it aint so...
- Thread starter gmh101358
- Start date
I used to be, but a lot of what you wrote is dated. Turbos, oils, and cooling has evolved. Turbo is da wey.

1. You have to use specific full synthetic oil. The same price as regular synthetic oil in Wal mart, but again, you have to get a specific one. It is in the manual. And people do not read it.
2. No, you do not have to idle for a minute. You can pull in driveway or garage, take off seat belt, turn off radio and that si it.
The reason why he has to change turbos is:
1. Guy buys used BMW and the first thing on BMW-specific forums is to open a thread with the title: "What is MUST HAVE tune for my BMW?"
2. If he recommends "full synthetic" oil of generic purpose, yes, that will do it too.
Err, the oiling issue is what I am referring too. Maybe it isn't widespread, but it happens enough to cause pause before purchasing.

There's no oiling issue with the HEMI.
How fortuitous that this video was just posted the other night
....and we all stress and debate over XW-20/XW-30....that poor motor led an abused life from the looks of it.
I guess the abused Honda and Toyota engines he’s torn down also had their fair share of issues outside the outright neglect and abuse as well
Ok.
I sense that you're projecting. Getting older is hard and for some 65 is the inflection point for senior citizen. I'm sure you'll be loved by friends and family for years to come.
Change is constant. Just like old V8s getting replaced by I6s.
Ya no more. Many turbo systems continue to move oil/coolant after shutdown.

For like last 25 years.
Over here V8's are a rarity and I got quite upset when a lot of the 'quick' day to day cars dropped their 5 and 6 cylinder engines for 4 pot turbos.
Only seems like yesterday you could buy a small Volvo over here with a 5 cylinder diesel or petrol.
I remember car shopping with my Father back in 2008 (14 years ago? How did that happen?) debating whether to purcahse a Volvo V50 T5 with it's inline 5 turbo or a E90 BMW 325i with it's inline six to replace his V6 Mondeo ST220.
Yes, the 4 pot turbos pull harder low down, but they just don't have the overal character their bigger older sibblings had.
That said, time moves on and who knows what I'll be driving in 10 years time.

How do they lack character?
overheating killed it. mopar had laughably bad press fit on valve seats across their entire lineup for the longest time

You did get to hear that Duratec V6 and it had a sweet sound. It is hard for a 4 pot to match the sounds of 6 and 8 cylinders. It can happen, but is pretty rare.
Turbos tend to muffle the sound, but improve the performance.
I think I'd rather be fast than merely sound fast.

Well, I've posted extensively on the subject
Here's a thread by @TeamZero where he shows the failure:
https://bobistheoilguy.com/forums/threads/bad-hemi-lifters.349339/
In a nutshell:
GM and Chrysler (potentially to a lesser extent it would seem) are both having a materials issue with some of their roller lifters. where the hardening of either the pin or roller is inconsistent or insufficient and eventually (depending on how bad the flaw is will determine how long it takes to crop up in units affected), the needles breach one of those surfaces and then they stop moving. Once that happens, they start to wear a groove in that surface and eventually the needles pile-up, the roller stops rolling and starts sliding on the cam lobe, it goes downhill quickly from there, as neither surface is designed to be in sliding contact.
I believe with the GM failure, there is a tie-in with their AFM system, as part of the failure, this doesn't seem to be the case with the HEMI and MDS.
GM was less cheap than FCA/Stellantis and used a billet camshaft, so if caught early, in many cases the cam survives. FCA/Stellantis uses a SADI core where there is only surface hardening, so you are guaranteed to have to replace the camshaft as well.
I'm not sure about GM, but with FCA/Stellantis there have been at least three revisions of the lifters trying to solve the problem. As both myself and @TeamZero posted in the linked thread, actual rate of occurrence is extremely low, but of course internet amplification makes it sound endemic, even inevitable.
I had originally thought that insufficient valve spring pressure might have been a contributing factor, allowing for some float, hammering the lifters, but that doesn't appear to be the case based on TeamZero's observations in the field.
Not sure about that last bit. I often think it was the sound of that Duratec V6 alone that got me hooked on cars.
I still remember my Father getting his first ST220 and taking me out in for the first time. It was a Saturday morning and we were heading down to the Gower in South Wales for the weekend. My parents had a caravan down by the sea for many years. Even better, this Saturday the sun was out, it was like 30°c and I remember hanging my arm out of the window playing with the breeze. My Father came off a roundabout (do you have them in the US?) onto a dual carrigeway and pinned the throttle in 2nd at about 4000rpm letting it sing to 7,250rpm, shifting into 3rd and holding her wide open to the redline again. To this day, I'm convinced if it was any normal 4 pot turbo in that Mondeo I wouldn't be into cars today. I remember the noise making the hairs on the back of my neck stand on end and being totally amazed that a 'normal' car would even make such a noise.
My Father had two ST220's over a span of 6 years and I promised myself I'd own one one day. I bought one in 2019 and kept it for about 18 months, my Wife used it as her daily driver for 12 months of that. Unfortunatley it was a bit of a dissapointment. The noise was as I remembered it but the lack of low down grunt that you get in modern turbocharged engines soured the experience a bit for me. Probably didn't help I'd had diesels for years that made a lot of torque much sooner than the Duratec V6 could ever make in N/A form.
