Yes, I'm stuck at the dealer waiting on the tow truck. Can't get in touch with them so I can imagine your frustration. Although they sent me a cable quick not long ago. Wish I had read the FAQ on their website about ecu updates. Wouldn't have came in. On top of that my problem isn't gone and I have a new problem.

Yea sorry man, trust me I know how you feel with your baby at the dealer waiting on a tow truck , I shuttled mine around on trucks off and on for 8 months. :( ..

Wow man.. that sounds like a long painful journey. I am in contact with Mike at UpRev so hopefully he can get me going but even then I'm just back to where I was before I left the house today lol. Can't help but feel like my engine is a ticking time bomb. Kinda kicking myself for going down this road. Feel like I wasn't really prepared for it like I thought. It's a blast but its also an expensive headache.

Plus after replacing my oil feed line and exhaust I'm still getting smoke out the back. My oil level doesn't seem to drop or burn. So.. either I have a bad seal on the turbo which I'm not sure I do after disconnecting the downpipe and it being dry as well as the charge side. Now I'm thinking I have a bigger issue engine related. Its just weird cause the car drives or drove fine minus the chatter noise.

Here are some pics of the exhaust and one of the front end without the bumper on. Thought I popped a coupler one day ended up being a MAF issue/code and I melted my under tray some after going down the road on a test drive. Oh well..

Does your turbo have a feed restrictor? A lot of turbos will get flooded per say with too much oil and it will leak out past the seal causing it to burn oil also if you have bad crank case ventilation the pressure will force oil from the turbo out the seal and cause it to burn oil that way as well

I've noticed some of the turbo kit for our cars just have crank case vents instead of rerouting them through the intake.

You know I'm not sure, I know the line that's on there now is suppose to restrict flow more than the one that was on there before but I guess the seal could be compromised. Bobby seems pretty certain it's coming from the turbo. The drain line doesn't look like it would restrict the flow out, no weird bends. Yeah I'll have to bring that up to him too, didn't think about that.

Interesting, yeah I gotta look into this.

In other news the guys at UpRev and Bobby got me running again last night! I was pretty down earlier in the day but they pulled through and got my maps patched for the new license since Nissan wiped mine clean with an update. Wasted $200+ for a update and tow for no reason. Made my problem worse instead of fixing it. I just wanted the VVELs checked and fixed oh well. She lives again to boost another day. I was worried my car would be down until next week but the guys stepped up and got me what was needed right up until closing. :tup:

Thats awesome, so just to clarify the original uprev tune was included with the turbo install and the dealer wiped the ecu clean when you took it in right?

Yes, my tune was done at VSR Motorsports which is included with the turbo install. The update to my ECM wiped it out along with the license. So I couldn't load my tune with the license being gone and part number changed on my ECM.

Yea those times were painful, On top of lose a lot of $$$$ 10k, ( Dealer screwed me) LONG story, Its on here :/
Did you get the "new" Map ID from him yet, I finally got my cable late on Friday.

I can't speak on behalf of other turbo manufacturers as I only have Garrett turbos in my car but I do know that as per recommendation from Honeywell they advise you o run a (and don't quote me on this ill probably have to find the information again) 1/4"-1/8" restrictor at the center casing. I'm not so sure that your seal has actually been wiped out just yet. Anything possible sure but I do know that just as Cosmo stated there are some design flaws in turbo kits on the market for our cars. No I'm not doubting S&R's ability to design a kit by any means but it is easy to overlook tiny little details that can cause persistent nuisances.
Do you have a catch can on your car midnight?

Yes, uprev came through on the same day and got me runnin again! Man that's not hard to believe.. Sweet glad you finally got that.

Yeah I still need to run it by Bobby. I hope it's not cause I really don't wanna send it off to precision but if that's it then it is what it is lol. I do have a catch can, it came as part of the kit.

Hey Willy, thanks man! Had it made at a local shop in Smyrna.

What's up guys.. So I sent my car back down to VSR to get something's worked out. I received word that it made it there today in one piece. I will let you all know when I get some updates from Bobby on the status. Stay tuned!

Got a call from Bobby today.. He seems to think it may have a wrist pin that's gone kaput. Looks like another built block for the boards will be in the works soon. Gave him the go ahead to tear it down and assess the damage.

Your motor went? They won't know for sure until the motor is completely disassembled. How many miles were on the motor and how many boosted miles did you have on her?

Well the motor hasn't gone but I think it is in some early stages. I was told it sounds like a wrist pin but yes until it's disassembled there's no way to be sure. I started hearing a ticking noise that sounded like loud valve chatter to me (untrained ear). This first happened right after I got home from Tampa. The car continued to run fine minus the noise which we thought might be the VVEL. So after months of enduring the nuisances it's had since getting it back I sent it back down to VSR. The motor had 15k maybe 15.5k when it got boosted and now has a little over 20k.

is your car a 6mt or a 7At?

Z

6mt

Oh wow, so you got the single turbo kit installed and tuned and noticed the knocking when you got it back, interesting.

Yes the VSR in house kit and install. Noticed it right when I got back after taking a buddy on a test drive we did a little 4th gear pull don't even think I went up to redline got off the interstate and started hearing the tapping pinging noise. Kinda strange but I guess maybe a bad batch of gas? We will see what the damage is but Bobby seems certain it's in the bottom end and not a head/VVEL related issue. Think I got the car back in April if I remember right.

DAH NAH nuh, nuh, nuh, and a another one bites the dust. HOw many motors is VSR up to now?

Even with a "bad batch" of gas there should be high detonation maps integrated into the tune to save the motor. That's what a knock sensor is made to do, but you can manipulate these maps in UpRev to not pull enough timing and add enough fuel. I could see if you are tuned for 93 octane, but put 87 in by accident and just ran the piss out of the car it may screw up a rod bearing or wrist pin, but having knocking issues as soon as you got it back after being boosted and custom tuned?... Makes you wonder

Yeah I'm doing a lot of wondering but at the end of the day it doesn't get me anywhere.. I think I made mistake going down this road but I can only choose to move forward or dwell at this point. I'm pretty sure I didn't put anything other then 93 in and like you said I would think the tune would be good enough to have some fails safes to some extent. I don't even beat on the car. Hell I was afraid of it at first until I got used to it. It's supposed to have a "conservative" tune as far as I'm aware. Maybe I just got the dreaded made on a Friday engine.. But I'm with you guys though, thought it would have more longevity. Granted it hasn't popped but something obviously failed.

I know the tune is very important but some times you just get a weak motor
why one motor can run at 500+ stock all day and another motor drops off at 450 is anyones guest
my motor died doing a dyno session with a stillen kit and yes it was a money pit to get fixed

now the tune i got from vsr motorsports ran flawless even thought we did have some other small problems. and the turbo kit has been great

Yeah who knows, with my luck I wouldn't be surprised if my motor was a weakling. But we won't know much besides speculation until it's torn down. My pistons were ordered yesterday. The 6 week wait is on for those to be ready. I think they have a good kit.. Stuff can and does happen. You just hope not to be that guy and that the work was done right. Guess this is gonna be one of those hard learned lessons.

Yea I'm still paying for it

just make sure they use good parts in your build.

because your going to want to push it and you dont want to second guest your build

Really? I would like to know myself. Far as I know none in the Nissan World.

Update

We hear a light tap coming from the rear of the Engine. At first we thought it could be the Dual mass flywheel.

We did a power balance test by shutting down each cylinder and no changes to the noise.

At low rpm's not very noticeable

At 2500 RPM's noticeable

at 3500 and up not so much

Under load only at low RPM not very noticeable. maybe cause there is the typical engine noise and turbo doing its thing muffling out the tick.

To us it sounds like wrist pin

The engine pulls like a train.

Now the Turbo is being sent back for warranty work. We had a batch of precision turbo's that have a smoke issue on startup.

Thanks

So you're saying you haven't had a single Z with your kit pop it's motor?

far as I know.

Valpozguy for one (whose car actually caught on fire when a piston came out the side of the block), I remember seeing at least two others on here and 1 guy off forum so you now you know you are up to at least 4. I'm not going to go into cars that have died on your dyno that don't have your kit as you never know with those.

Edit: although if you are using knock voltage to tune it all makes sense.

Sorry to get involved... But......
This is me right now :eek2:


Bobby, are you stoned? I know of peoples' engines that have blown with your turbo kit too...


Oh, and if you're going to be a non-paying vendor please :gtfo2: or take your contact info off.

Are these guys not calling VSR and telling them they just blew up? I know about 3 off hand. I find this hard to believe he don't know a single VQ that's blown from his kit.

Or Bobby's in denial lol

Who was the guy that went to VSR and had their motor blow and made a big thread about it?

Infidel I believe, but vsr is currently ordering him parts for his motor for a rebuild... Never boost your daily driver, poor guy..

I don't know of any 370s with the VSR kit that blew their engine. I try to pay attention and keep track of everyone who does have the VSR single turbo on their 370Z to see how everyone is doing in relation to my own build. I've had the VSR kit on my car for over a year now, since Aug 13. Its been my daily driver, been on several long distance road trips (over 500 miles round trip), dyno'd at 4 different facilities (VSR, Motion Lab, Z1, Soho Motorsports), driven hard and done several 1/4 mile runs on drag radials. My motor is still alive and still seems to be pulling strong with no problems.

Yeah, Infidel was also using the GTM supercharger kit and had an issue with the BPV/BOV I believe. They had a hard time making boost for some reason think it was a leak somewhere. He didn't have the VSR kit though. Poor guy didn't even get to experience the car with power.
