Mazdaspeed 3 / 6 K04 Turbo Upgrade - 330WHP!!!

[240ka]

why were you running 25ppsi on our Turbo.

that doesntmake any sense. 21 is pushing its limits, hell itsat its limits

 

[cpolly69]

when your k04 seals are bad 25psi is the oil pressure where the shaft moves enough to start to leak oil into the exhaust side housing and get burned off - i should have been more clear - 25psi oil pressure not boost

lol i would love to see a DD ~400 hp ms3 lasting at least 3 yrs with 100k miles

Raise the octane or lower compression is the old school way to deal with knock. And watch your egts. if i run 100 octane will the knock sensor relax its grip on the ecu?

 

[cpolly69]

that's a negative - at least with the stock ecu map anyway - i've got a sunaco near me that sells 100 and 110 and i have ran both and still get a little knock around 3k and various points thru the band when it's cold

 

[ericrapp]

That is a shame. i would have hoped that might've helped. I will run the 100 octane from our Delta sonic when its hot and i am going to track or run the thing especially hard. Not data logging, i have no idea. Is the knock sensor overly sensitive on our cars? I guess my next question is, being a boost novice, if i move into a compressor map that comes from installing a big boy that lets me blow cool air to 6800 at less boost does the knock go away. And of course the timing retard. Help me out and if we need to move this to pm please feel free. And maybe that is the point. even though a clipped and ported k4 can spin more boost it still is limited to an rpm range? i have 43k on mine and beat it up often but never add oil... How are you logging your data?

this week i got my new k04 from the dealership installed on wednesday - saturday i installed my dp/rp & inlet - then i drove about 75 miles - and that was the end of those oil seals! it already smokes after about a min at 25 psi -

when your k04 seals are bad 25psi is the oil pressure where the shaft moves enough to start to leak oil into the exhaust side housing and get burned off - i should have been more clear - 25psi oil pressure not boost ~~{ WHAT?????-}~~

25 PSI of Oil Pressure..?!?!?!? This is insanely low .......Idle should be 25-30psi! I found these tidbits using Google:

idle @ operating temp (~185-degF) = avg 23psi

Running 5w40 on the speed3...idle @ operating temp (~185-degF) = avg 28psi
Running 5w30 on the speed3...idle @ operating temp (~185-degF) = avg 23psi
5w40 on speed3 ... cruising at 3000rpm @ operating temp = avg 70psi
idle @ operating temp (~185-degF) = avg 23psi

Either you got a bad gauge/sender....Your oiling system works the exact opposite of the way it was designed.....You read the gauge wrong.....Or you You just said Oil Pressure to cover up the fact your over-boosted your turbo twice LOL ...(ohsnap!)

Seriously... the turbo probably overheated instead of breaking the seals because of high oil pressure ....or..... you exceeded the max boost limit for this car and over heated the turbo .....or.... your sender is bad, if this is the case, you wouldn't know what the pressure really was.

He's just using the exaust portion of the core.The fun side is upgraded with garret pieces and is a bit larger than the stock K.

no i just have a cheap cobalt oil pressure gauge with the sending unit plumed in at the stock location and at idle it drops down to right above the 25 mark (which is probably 28 just like you said above b/c i'm running 5w40)- i could post a vid if it would make you happy -
can google tell you what the pressure is actually at the turbo?
there's nothing wrong with the oiling system or my sender - the k04 just is a piece of crap that can't handle the lack of back-pressure - i also monitor the egt with my dh and it was actually lower then normal and has been ever since installed the new dp
i did everything the way you are supposed to and i didn't over heat the turbo - it just blew the seals

 

[evilmonkey]

Dude .. relax. from what you said, you ran the car hard for a minute @ 25 psi....either way 25psi of boost or 25psi of oil pressure is gonna fubar your turbo...I'm just trying to figure out how, from what you said...it just doesn't make sense.

I haven't checked google for pressure @ the turbo but logic tells me it will be a hell of a lot higher than 25 psi when ran hard, and it would be slightly less then average 25psi @ idle after moving through the oiling system.

90% of us with these cars have the same turbo with mods(except for those who upgraded) and don't have blown seals but you gotta remember this is the factory turbo and it was designed to work with factory DP that provides enough back pressure for the k04.
You cant expect it to excel with mods added that directly effect the operation for which it was designed

I would say its pretty hard to drop 1100/1300 bucks on someones word. Dynos/Videos of the thing running might make it easier.

 

[cpolly69]

i personally think it will still leak oil just like all the other journal bearing k04s unless something is done to improve the supply and returns lines/fittings and because of all various setups no one will know it's leaking - hell half the folks out there with smoking turbos now don't know they are b/c of their cats and the other half will fight to say there's nothing wrong with a turbo that smokes a little

ill stick with 600 bux and a reworked turbo from PG and pretty much get the same thing out of it, daily driven anymore than 350hp on these cars are trouble if you ask me...

350hp so far seems to be a breaking point for the connecting rods on the 2.3 DISI. DCR believes with better fueling they can make more, time will tell on what solutions they have in store.

This isnt a rebuilt turbo its a k04 shell with brand new gt28 guts...Nothing like a rebuilt k04.

 

[cpolly69]

i don't think saying it's got garrett guts is entirely correct - it's still a journal bearing turbo - not a ball bearing turbo (gt2871 is a ball bearing turbo) - yes it may spool faster and make more hp then the rewrd or standard k04's guts but the questions i haven't seen answered still remain - leaking oil into the exhaust housing? - interactions with knock retard? and lean spot in the fuel ?

Cant answer those for ya until its built : ) Hopefully in a few weeks the turbo will be finished and me and monkey can get them on out cars and get some definitive results. Not sure if you are a member on the "other" forum because neither of us really post much here...

 

[cpolly69]

yeah i'm on suf and msf - i made a reference to it a few posts back along with all my wonderful ?'s

ok thats all fine an good, but, what i said was... why spend that much on that when BASICALLY for 600 you will get the almost the SAME gain from just a rebuilt turbo from PG? and if i was gonna spend that much on that, i'd say **** it an opt for the gt28 in the first place. not much bigger than the k04...

 

[GiJoe]

yeah... you can pay 1100 for a whole new turbo thats good for more HP....
