200k+ miles with turbo?
 

just wondering if anyone has turboed their high mileage engine, and it actually survive the chaos! >:D

Re: 200k+ miles with turbo?
 

Nope. Never. Everyone here just pays somebody to build them a zero mile monster. Homemade is just a joke about poor people that turbo their rides with junkyard parts on high mileage ---- heaps from 15+ years ago. We're all really ballers that have 5 figure checking accounts at least.

Re: 200k+ miles with turbo?
 

I've put all the trailertrash with 5 figure checking accounts on block. I do not have time to deal with the lesser classes of people.

Re: 200k+ miles with turbo?
 

The formula goes:

Take 200,000 divide that by [(amount of boost you're going to run in psi) * 10000]

i.e. 8psi would be 200,000 / 80000. That comes out to 25. Mutiply that by 1000, we get 25,000 miles.

Now do a compression test on your motor and if it checks out go ahead and boost it.

Re: 200k+ miles with turbo?
 

Just rebuild it and put low compresion pistons...

Re: 200k+ miles with turbo?
 

dude quit giving advise.

Re: 200k+ miles with turbo?
 

Get out... Your not helping

Don't you have a day job sweeping floors?

Re: 200k+ miles with turbo?
 

Comp/ leak down test will tell you all you need to know.

Re: 200k+ miles with turbo?
 

lol some of the posts are pretty comical, i agree with the compression and leakdown test, sounds like a plan. I do however like the milage/boost equation lol. I only ask this because theres never any successful high milage builds, most like because they break, and honestly i just dont have the time to rebuild my engine. Thanks for the good stuff, and the laughs ;D

Re: 200k+ miles with turbo?
 

good luck... first setup always BOOOOOOM...!

Re: 200k+ miles with turbo?
 

My car has a D15b7 with 200,000 miles on it and I have been boosting on it at 8 psi for over a year with an Xenocron basemapp.

Re: 200k+ miles with turbo?
 

d15b7 with 219k miles boosted for two months, took some serious abuse but rods didnt like 14+psi boost spike, other than that I was running 10lbs all day everyday.

Re: 200k+ miles with turbo?
 

I had a 200k+ KA24DE that put down like 300-330whp for years.

Re: 200k+ miles with turbo?
 

I put a centrifugal supercharger on my 97 Mustang when it had 107K on it. 206K later, the supercharger broke a bearing and had to be replaced. I ran the motor up to 321K with blowers before I took the still-running-well motor out and swapped it for a built 4 valve V8 with a larger supercharger.

My turbo mustang is has a rebuilt motor so cant say anything there. The original motor I mocked everything up with I replaced

hahaha

Re: 200k+ miles with turbo?
 

lol my z6 has around 270k on it, im the second owner and know the first owner so i know its very well taken care of. I have been tempted to boost it with 8psi on a homemade kit, i just didnt think there were any success stories with high mileage. it would basically serve as a quicker highway driver, 40 miles a day back and forth to work. thanks for the input guys, i think a leakdown and compression test would be what sways me to either swap a d15bvtec engine/tranny combo or put the high mileage to the test.

Nope he got fired for stealing brooms

Re: 200k+ miles with turbo?
 

Boost the high mileage motor

Re: 200k+ miles with turbo?
 

The tune is going to be key on any motor. If you have good leakdown etc. go for it. If you don't go for it anyway and start your new motor build while you are working out the kinks with the old motor/turbo setup.

Re: 200k+ miles with turbo?
 

as long as that goes well and i replace some gaskets i dont see why i couldnt try some boost, start out low 5-6 maybe see how it responds. thanks for the posts guys, more than ever it makes me want to boost 270k miles strong!

Re: 200k+ miles with turbo?
 

10 pounds turns ya out

Re: 200k+ miles with turbo?
 

;D

Re: 200k+ miles with turbo?
 

seen one with 350+
head lifted and puked out coolant
through in ARPs - 10 pounds turn you out ;D

Re: 200k+ miles with turbo?
 

D-series don't lift heads, and having ARPs don't fix that problem. Stop feeding the engine so much goddamn timing fixes the problem.

Re: 200k+ miles with turbo?
 

JD, it is the problem. Decrease timing is just a hack that results in simply making less power. My car made almost 20 more whp at 18psi, with the appropriate amount of timing; however, even with arps it still lifted the head. Had to pull timing to keep cylinder pressures low, but resulted in less power.

Small headstuds, and a small bore, doesn't go well with high power per cylinder.

Re: 200k+ miles with turbo?
 

Small head studs can be fixed, this is why ARP has custom age 625. If that isn't enough you can always o ring the head, if still not enough you can o ring the block as well, if still not enough you can goto fire rings, if still not enough you start tying the head to the mains. ect... There is always a way to make it seal, it is just how much are you willing to spend.

The other thing that seems interesting is that there are more and more 400whp+ d's popping up everyday, looks like lots of people have figured out how to keep it together.

Re: 200k+ miles with turbo?
 

I thought he just sodomized the brooms? He has 'that fetish', you know.


As soon as it warms up to bring my other car out of mothballs, I tossing my old kit back on my cureent EF beater. Its a 150k D15B2 that has more blowby at idle than a ringless engine, but I have 2 other D's I can put in easy as pie just in case. I also turbo'd a '92 z6 that had unknown milage, was pretty dirty, and it took 10psi on uberdata before it started pushing coolant past the reused HG/oem bolts on a s-trim.

As long as you have a decent tune, old D's can take decent boost levels.

Re: 200k+ miles with turbo?
 

You had already breached the headgasket and it was a degenerative condition. That is a reflection on your already blown headgasket and not on the veracity of what I have said.

I've been through more 400+ whp D-series than anyone on this site except maybe leed, and every last one made best power at best safety. I also started off with a LOT less timing than anyone else I know of, 94Sewell has seen a few of my maps and can attest to this.

Re: 200k+ miles with turbo?
 

So you always reach MBTT before coolant?


It actually wasn't blown. Sealed up completely. Dropped it back down to 10psi and still made the 240 it made before. Motor's run strong and is beat on every single day for at least 3 years now.
