Omg... help

[SeR_Cyclops]

ok guys i cant find the problem. ive posted on this before but everyone tells me to check my waste gate and vac lines and i have countless times. on lets say a 32 degree day i will hit fuel cut at 4 to 4.5 grand depending on the temp and now i look over at the boost gauge and im freaking boosting 15 psi!!!!!! i have replaced the wastegate (stock was bad anyways) and pulled vac on the lines countless times. im completly lost.... any idears? ill try to post a video when i get home but guys really its killing me!

[Blackrose]

The swing gate in the turbo is probably seized. If you replaced the actuator and checked ALL the vac lines that is the only thing i can think of. Would suprize me either. Mine warped at 30K miles. Only difference is mine would not boost. But there is a chance yours could have expanded in a way that it locked it into place.

[Blackrose]

And i wouldnt bother making a video of it. 15psi is very bad for the motor. Make sure you take it easy on that throtle if you plane to drive it. You will blow that motor quick at 15 psi

[SeR_Cyclops]

how much will it cost to fix i dont think that thing siezed because when i put the new waste gate on it moved but it could have broke off b/c when i think about it it swung really really easy.

[MP3Architect]

i would recommend contacting theman or bryan...they're pretty damn knowledgable.. maybe even jdmsam

[Blackrose]

It should not swing very easy. Did you double check to make sure you hooked everything up right? If it is the swing gate you are screewed. It would be expensive and laborous to fix.

[orng1]

Be careful with it, there is a small C clip that helps keep the actuator arm on. I almost lost mine when I removed the turbo once. If everything looks fine it maybe time to remove the turbo and inspect it, maybe it's something simple.

[SeR_Cyclops]

yeah that C clip we call a jesus clip becuase when they come off only jesus knows where they went. the labor would be free. i can do it my self. and what i cant handle my dad works on cars for a living
so how much would this cost

[Alejo_NIN]

ok, i don't known what type of turbo is that guy using, but both my Turbo's wastegate , miguel's wastegate, and serg's wastegate, and yet another msp's wastegate..all of them swing freely
actualy, i think if it is too hard it won't open in time.

do this...have the wastegate actuator vac line BY ITSELF
do not TEE it off to anything, just run a straight line from the manifold to the wastegate...
preferibly a new line.
make shure the line doesn't have any holes on it..also, if so equipped, run a dedicated line to the BOV, the rest of the vacs can be tee'd from one source, you have plenty of sources on the manifold.

if it is still boosting 15 psi. make sure you dind't get the ATP turbo higher PSI wastegate, make sure you got the one that says 8 PSI!
i do know there was one for 12 psi also.

[msp35]

IIRC my WG flap swung very freely, after the ATP install I was boosting 6-7 psi like it is supposed to. Maybe the old WGA was accidentally installed, or like Alejo suggested you received the incorrect WGA....

[jmv]

actually it should be 6 psi. At least thats the one i'm using.

[Alejo_NIN]

yea yea that one..sorry

[SeR_Cyclops]

i installed my self didnt take long we didnt have to remove the turbo or anything but they could have sent the wrong one.

[Alejo_NIN]

check this pictures against what you have


see if the numbers match
the old one is the one with the nut in the middle and it looks very old and used

the new one..well..looks new


i installed my self didnt take long we didnt have to remove the turbo or anything but they could have sent the wrong one.

[SeR_Cyclops]

i will see if they match tomorrow are the numbers going to be a bitch to read or no? b/c that little heat shield is prolly in the way.

[orng1]

If you can't see it try a mirror and a flashlight. usualy does the trick.

[Alejo_NIN]

i can only do so much :P

lol

good luck dude

i recommend waiting til the car is cold...is a bitch getting burn with the exhaust many..and i don't think you would like to have a "calway" tattoo in your arm

[SeR_Cyclops]

so does anyone know where to get this part if the internal wastegate is bad or should i just try and get a used turbo

[Blackrose]

What part?

If you do have a bad swing gate you would probably need to replace the turbo. I think there are a couple peeps selling uised ones in the FS section. If you have to know how though it would be worth it to just yank the thing down and have a look at it. If there is a problem with the gate it will be noticable.

[SeR_Cyclops]

this freaking sucks so what could be messed up in there is there any chance of saving the turbo?

[orng1]

Take of the turbo it's worth it to remove and repair it if you can. I've got it down to about to 45 min now, most important is to remove the intercooler/radiator first before anything it will come out as one piece.

I replaced the internals of my turbo for $550.00 Canadian.

GT-28rs..

[Alejo_NIN]

you converted your gt25 to a gt28rs using the same housing?

i'd like to know more about this...

[Brian MP5T]

No, it was a GT-28 before as well

[SeR_Cyclops]

well what would be wrong with my turbo? it would be in the wastegate right

[SeR_Cyclops]

does a t3 turbo fit as a direct replacement to a stock turbo?

[OrngSpd03]

My MSP hit Fuel Cut today. I have a CAI and stock boost. at 4k rpm its like I hit a brick wall. It only does it under High Boost. If i creep it up to 4k it doesn't cut. It seems to be related to the outside temp. usually below 40 degrees outside. Did everyone who changed their wast gate actuator fix the problem. I still have 30k on my 100k warranty. Is this something the stealership will fix?

Looks like there is oil leaking from the feed tube on the top of the turbo. I hear this is a common problem. Does the turbo need to be replaced or can that be fixed?

[Kypatrick]

Hearing about all these problems with the Turbo components, almost scares me into trading mine in!

[Alejo_NIN]

all fo you, why not just sell the car?

buy something more dependable

i guess MSP's re just for hardcore mechanics....

Are you tellin me its junk and always needs a mechanic?
Is the guy with the boost problem stock?

[evilmonkeyMSP]

if you plan on cranking up the boost over 10 psi w/ out a lot of supporting mods on the stock internals then its best that you are a mechanic or know a good one :)

[orng1]

No the car is not "junk" it's just poor design or thinking by the engineers. The guy that is hitting fuel cut probably has a leak in the charge pipe or is running higher boost that he realizes, what does your boost gauge say. I have hit fuel cut but it was real cold at night and I have always been around 9psi and as it gets colder it goes higher for some odd reason. Being a mechanic does help as the car is not put together all to well (turbo kit) and needs help often.

[Kypatrick]

I guess i took Alejo_NIN comment wrong. I understand that there are qwerks with the car, and it might need some attention. I need to watch what Mods i do to the car, im not very car literate, and dont have alot money ( have a family to support) so i seem to be at a Disadvantage. Apparently its a good idea to ask on here before messin with it.

[Brian MP5T]

Boost to 40 Psi...

[orng1]

LOL 40, so 8X what we run stock. I have mine at about 1.5X as much as stock and am very happy with that. We have to be careful what we say, some people might take it literaly.

[Brian MP5T]

Boost to 40 and you will have no problems..

You will just have to get a MS3

[Kypatrick]

How do i do that. Ill just tell the wife I dont know what happened!

[Brian MP5T]

Atta Boy..

[SeR_Cyclops]

yeah im stock

[SeR_Cyclops]

my car is stock and the boost holds at 15 psi its not a spike. i hit fuel cut like a mutha fuka on a day thats around 40 deg and i get it around 4.5 rpms even when im not getting on it... ive got a guy thats really good with cars.

[OrngSpd03]

took mt MSP to the dealer first thing tuesday. According to my the service manager, this is a common problem. Seems it is a defect in the internal diafram in the mechanical wategate. He knew exactly what I was talking about, and immeadatly said its your wastegate I'll order you a new one. Obviously its not the firsty time he has seen the problem. They are replaceing my oil feed lines as well. If that does not fix the leaking oil they are going to swap turbos. Glad they are taking care of it, but I wish they would just go ahead and put the new turbo in instead of going with the "one part at a time and see if that works" fix.

[Mustard97]

msp's are actually very reliable if you don't do anything stupid to them, i'd rather have a msp then a ms3, i trust the old FS engine more (and i work on these things for a living)

[orng1]

First of all I don't think 15 psi is stock there is something wrong there, whether it's intentional or not is something else. Second, are the FS motors really better than the DISI or whatever it's called?

[Brian MP5T]

NO.Period.

FS < DISI


The FS needs to be built before it can be boosted past 7 Psi.

The DISI, comes Boosted way past 7 Psi..
<disi></disi>

[SeR_Cyclops]

anyways im taking my turbo off today and checking the internals... if they can be saved i will and if not ill put it back on and get a stock

[Kypatrick]

NO.Period.

<disi></disi>

I think its stock at 15 (DISI)

[Brian MP5T]

15 is over double.. IMO that is "Way"

[SeR_Cyclops]

ok we took the turbo off and its not the waste gate. but we did figure out what the problem is.
the person that had the car before me for some odd reason switched the lines that went from the wastegate to somthing else. we know for a fact that its wrong b/c where its hooked up no pressure is coming out from where its connected to open the wastegate... i called mazda and they wouldnt give me the digram b/c i wasnt going to buy anyparts and then hung up on me so thier jerks but can you all help me out by posting pictures or giving me a link where i can find out where i need to hook up the line that comes from the waste gate??? please help..

[SeR_Cyclops]

comon guys im so close to getting it fixed.
