:iagree:

This is common with sts.. That's why I tell people to go with the oil-less turbo if running the butt mount. How big is your air filter? The check valve working?

White/ blue haven't driven since it happened

What's common ? Seals going? My air filter is the one it came with idk the size is and I also don't know what the check valve is : (

You might want to check the your oil lines running to the back feeding the turbo. If it's spitting the oil into your turbo that could be creating the issue or the pump is clogged up and creating a back flow issue. Check all the connections. Look at the little blue thing (your pump for the turbo) which is located in front of the turbo bolted to the under belly of the car.

Really, again with this :bowrofl:? My guess would be if that's the case will most STS kits they would no longer be in business.

I would not recommend oil-less turbos on a street car. They are built for the drag strip.

I have sold almost 30 mid mount systems for the 350z, and not once has there be an issue with the oiling system. I do however use a pump that is 3x the cost of the pump that STS uses.

More importantly, I use brand name proven (Precision) turbos. Who makes the STS turbos? There is no "brand/manufacturer" stamp is there? If they are not made by Precision, Garrett, BW, Turbonetics, Holset...ect. where do they come from?

I know plenty of people/cars who run oil-less turbos on a DD w/ no issues. Not saying it's better than oil, but it is a nice alternative. I've got about 4k on mine, inspected it the other day, no crazy shaft play, still spinning like a champ.

They build them in house when you buy the kit

I also don't think it's the pump either , we just hopin it's the seal on the exhaust side

Having issues? Call STS . I will let Vernon know that your having issues.

I don't know how much Vernon would be able to help him. I hope it's something simple man, I'll be taking mine in next week to a real tuner to see what kind of numbers @ 9psi it'll give me.

Vernon can direct it to Rick. Rick has helped me a couple of times with the kits we installed and helped out. The kit boils down to the tuning. Tuning it the biggest thing with these cars and making sure the parts are installed correctly.

It's not the tune it's the turbo 99 percent sure , the other 1% is head gasket

Wow you're an idiot. I've been around sts kits since the first ones came out. Now please go away so I can help.

The oil inlet to the turbo has a brass piece in it with a check valve. This valve is intended to keep the oil from flowing into the tubo housing after the vehicle has been shut down. If it does fill up the housing over half way it is possible for oil to flow past the bushings into the exhaust/intake compressor housings. On start up this oil will be forced out the exhaust or into the intake. The idea is to test the operation of the check valve.

And the filter.."The K&N Pre-charger filter cover is for normal driving use to keep the filter clean during wet and/or dusty conditions. This cover has nearly 1/10th of the surface area of the actual air filter and is restrictive to air flow. The turbocharger will pull air through this cover by creating a vacuum between the filter and the turbocharger. If the cover is dirty, this vacuum will completely collapse and destroy the air filter. This high vacuum will also suck oil from the center section of the turbocharger into the intake piping. Remove the Pre-charger filter during any hard acceleration, racing, and or dyno runs. Any restriction in the air filter or cover will cause intake temperatures to rise dramastically during boosted conditions."


Check Valve Test:

1.) Take off the braided oil suppy line at the turbo center housing.
2.) Remove the check valve from the turbo and re-attach it to the braided oil supply line
3.) Place the line over a drain pan and start the vehicle. Let it run for a few seconds until there is a flow of oil through the chack valve.
4.) Shut off the vehicle and place the line and check valve on a few sheets of newspaper. There should not be more than a drop or two of oil leak out of the check valve onto the newspaper.
5.) If it leaks more than a drop or two of oil then get hold of STS and have it replaced. They will probably warranty it if the system is not too old.
6.) If it does not leak re-install the fitting and oil line to the turbo and get hold of STS about possible repairs that may be required to the turbo.

Thanks for the info, now I know who not to buy from.

I don't think it's the air filter thing you mentioned , since I had my rain sock off at the time i didnt have time today to tear it all apart , im gonna try that test you mentioned and I'm also gonna test the oil return pump. Thanks for the info 96 big body

This still doesn't explain the check engine light :(

K so guys , we took everything apart, the turbo the exhaust , everything checks out except for a frothy mess in the turbo , the ecu code was 0P005 ( I think, I forget the exact numbers) but it ment ECM failure :o so Itthrew the car into limp mode and dumped all the fuel out the exhaust? Does this even make sense? Does limp mode make our cars smoke ? Can some one tell me what happened? I erased the code and the car runs like a raped ape again, what's the deal? Any help is appreciated

our sts 370z has been having some error codes as well p1006 or something like that (sensor error) and check engine pops up again , we deleted it but it comes again , once on wot the car shut down by it self and smoked like hell for a sec when it shut off but once started again it never happened again, but the code is still their and we just accepted it as is and left it alone , the customer likes the kit , but we have been having boost leak issues , a couple of the exhaust couplers that were deleted and welded to fix the issue and stopping it from comin.

hope this helps :driving:

Hmmm weird , my code is gone now , but about the the exhaust leaks how did you find them? And that's basically what mine did I was wot and boom limp mode and smoke , the car stayed idling tho

we did a boost test leak by using the mechine the uses 2 methods first of all putting pressure in the intake by removing the air filter and placing it there and then after marking the leaks places by hearing them we use the second method which is white smoke (vaporized smoke :bowrofl:) to find little places that we might have missed , from wht i read the sensor in the intake doesnt take much pressure at once so it goes crazy their is a section in the uprev tuning in the DTC section to by pass it but we couldnt enter that section although the ecu is not locked but its limited for the tuner to enter everywhere unless he uploads the map from his wire which means the map in the car now gets deleted:icon14:, the code we get is P0106 MAP/Barometric Pressure Circuit Range/Performance Problem, and regarding the crazy shut off dont know why it happened or if its attached to what i am mentioning above , but i could reassure you that my customer didnt have any problems with his gtm stage 1 kit , not even a check engine or anything just had coolent temps problems and thats due to our 130f minimum heat :eek: , not bashing here but just sharing real facts that have happened and ive seen them , again all kits are amazing , but i guess these 370z's are just too sensitive .

If anyone has any info on why my ecu would do this please chime in

Have you contacted STS, try Marc.

Sorry guys I've been missing in action for a whole we reset the ecu, and reflashed the car runs strong and has been for 1000 k, no one knows what happened or why but it seems to be fine

Good to hear that your back on the road able to enjoy your ride:driving:

How many miles have you put on your Z with the STS?

I have about 6,000 km's on my kit, so far so good. Sounds and performs great!

1200 k ish I love it

Great to hear! sounds like I may be seeing you in a few weeks for some dyno tuning! Good to hear, looking forward to meeting you. How many lbs of boost are you planning on running with this tune?

9 probably I gotta get my boost controller and meth injection on

I was aiming for around 9 as well what meth injection kit did you go with?

I had a check engine light as well but it was due to the tune. Once Marc at STS sent me few new tunes the issue was solved but with the shady install of my system I have two exhaust leaks currently. I'm having my new tuner change out the clamps for flange connections and he is also going to move the AFR "sniffer" where it belongs...AFTER THE TURBO. Also gonna push 9-10 psi on the system to see what it can handle (with the meth injection system).

Do you have any pics of your system? what kind you went with?

I think Tower used STS's setup, I chose to go with Snow performance boost cooler 2 setup, I have a few pics on my profile, hope to update with some more. Install was pretty easy, just awaiting a tune to see the true benefit.

Thanks Im looking at Snow also, I'll check your photos out.

That is a nice custom tank you have, what size is it.

Are you gOnna tune it for meth or just use it for safety ?

Thx the tank holds about 5 liters

Probably as a safet, but I was gonna talk to the tuner beforehand to see what he recommends, mark at Sts suggested tuning it without and then using it as a safety.

Yea thats exactly what I was thinkin
