The messed up thing is she wanted a wake boarding boat really bad......so we got one awhile back....all the bells and whistles....not a cheap thing to buy. It doesn't bother her at all with the cost to own one of those....the car on the other hand seems too :wtf:

I dont plan on keeping the boat either now.....if the car doesn't make sense neither does the boat right? Not financially smart to have either.

Makes more sense to keep the boat and the car and get rid of the wife. :tiphat:
You're :welcome:

Its been a little bit since I posted any updates. After the slight hurdle with my wife not agreeing with my hobby I figured out how to keep my Z and keep her happy. I ended up getting her a BMW X5 and now it seems like she forgot I even have my Z. So lesson learned buy her something she wants before any big Z purchases lol.

Back to the Z, I ended up taking everything off/apart to clean flush all the aluminum out of the engine and IC, piping, BOV ect ect with repeated oil changes. Put it all back together with the new Comp Turbo and got it tuned locally.

Not bad, 438hp 364tq to the wheels on a mustang dyno 91oct around 10psi. I would of liked to see more but with a tired motor that's been fed aluminum I can be happy with those numbers for now. Tuner said main thing holding the car back was 91oct Cali gas :(.

Car is a blast to drive besides traction loss even at speed. Just ordered some 18inch RPF1 9.5 F 10.5R .....not sure on tires yet but probably 275F and 295R size wise. Next after this is to probably start secretly getting my motor built and a return fuel system for either e85 or just run streetblaze 104 from a local station or even just buying the 5gal VP or Sonoco stuff..this will be awhile before the motor build happens unless this engine let's loose hopefully not destroying everything in it's path.

Go with 275/305 on the tires. You don’t want to mess with the stagger.

Why did he stop the pull at ~6800 RPM?

He said something along the lines that his readout on the dyno stops there.....but it's tuned to redline. I thought that was a little weird and I'm not even sure what my rev limit is right now. Some of the members on My350z said the torque numbers don't look right for having 438hp and only 368tq. A suspicion is that I may have a VTC solenoid issue and I should try to see if I'm getting a full duty cycle out of them....I'm not sure how to even do that but will research that.

I messed up and bought the staggered 9.5 / 10.5 RPF1 combo from Oakos Auto...it will probably be okay we'll see. I went back and fourth so many times, reading threads, searching forums I just pulled the trigger.:confused:

The stagger is fine but you want to keep it to stock stagger difference. The stock was 245/275, so go with 275/305.

Ghost116 02-20-2018 08:58 PM
Is the octane limiting u? Or lack of fuel pressure? I’ve heard of a lot of guys getting stuck around 475. Planning on going bp next year, and hoping to break 500 in 93 octane.

93 octane is not an issue up to 560-580whp.

That’s what I figured. Prob end up with a fuel return just to be safe. But most pumps around me have 93

**update long story short kept the car and Comp covered first turbo under warranty**

Since being tuned I've put on about 700 miles with no issues....until today. I lifted my car up to just check everything out underneath the turbo and exhaust are and noticed that the Comp Turbo oil-less zerk fitting is no longer there. Please keep in mind that this is the second turbo that was sent to me from Comp under warranty. At this time I am unsure on how bad this is. Without the zerk fitting being there I am assuming that the oil has been leaking out of the hole....how much and how long I do not know but I assume its not a good thing. The zerk fitting hole does not appear to be a threaded piece since no threads are visible on the zerk port. I will be sending Comp a email here shortly to see what they think happened but was hoping members with the boosted performance oil-less turbo kit can chime in or Sasha himself.

SouthArk370Z 03-31-2018 10:37 PM
Remove some of grease from the hole (a Q-Tip is handy for such things) and see if any of the zerk is in there. This will tell you if it broke off or unscrewed itself.

knuckles899 03-31-2018 10:49 PM
It doesn't look like there are any threads... when you look at the pic no threads are visible in the center housing.

Rusty 03-31-2018 11:08 PM
Might be a pressed in zerk that fell out since there are no threads.

The threads would be below the camfer.

Or, as per Rusty, it was pressed in. I kind of doubt this as most grease systems are fairly high pressure, but I'm no expert.

jchammond 04-01-2018 07:03 AM
I've seen the pressed/drive in zerk fittings on a dump truck body,,,but couldn't imagine it on an expensive Turbo.
Hold on......This must be an "April-Fool's Joke"

If this is a pressed/drive in grease zerk & the only one on your Z that is lubricated;
look at your grease gun fitting & see by chance did it pull out the last time you greased it.
I've had this happen at work before & ended up tapping hole & using a thread in type.
Just a thought.

Boosted Performance 04-01-2018 08:56 AM
I will be on COMP right away to get this figured out. I believe these are pressed in, so one can't simply pull hard when disconnecting the grease hose from the zerk. Common practice is to push the grease gun (hose end) fitting to one side until it pops off, instead of a straight pull.

I understand that this may have fallen out at some point during operation, which is not right.

I will make a suggestion to have these threaded in as well.

jchammond 04-01-2018 09:21 AM
Rapid response from "BP",,,that's awesome customer service!

I haven't greased it yet since I've only driven it around 700 miles or so. Good call though, I could see how a non threaded zerk could stick in the gun if it really wasn't pressed in tight.

Thank you Sasha for the fast reply, I am curious to hear Comp's response on the cause and what they would like to do. One of my concerns with the grease fitting falling out is that the grease when heated in the turbo liquefies and is supposed to cool/lubricate the turbo from what has been described to me about these oil-less turbo's. Without the fitting there I can only assume that the grease has now leaked out basically running the turbo somewhat dry or just not efficiently lubricated/cooled by the grease anymore possibly causing this turbo to prematurely to wear.

I've worked on a lot of equipment that had pressed in zerk fittings. Had to replace a bunch of them too. Grease systems are not high pressure. Once you remove the gun. The pressure goes away. When greasing. Once you get the first fill of grease in. After that, you only need two to three pumps of new grease into the bearing. Any more then that. You CAN over grease the bearing and damage it. Some bearing housings will have a plug 180 degrees away from the zerk fitting. On these. You remove the plug and grease until you see some grease start to come out of the plug hole. When you do, stop greasing and install the plug.

Boosted Performance 04-01-2018 05:12 PM
From COMP:

He can reinstall the fitting we can send one out tomorrow very easy install . Or if the customer doesn't feel confident we will pay for shipping both ways .

The stem is indwwd threaded in to the bearing housing.

This is what makes COMP the company of choice for me. It is Easter Sunday, and issues are getting resolved, and customers are being taken care of.

Rusty 04-01-2018 07:56 PM
The next time OP greases the turbo. Only do 3 pumps or less to grease. Don't try and force the grease in. When the handle starts to get hard to pump, STOP! If You try and force it. You are now using hydraulics, and you WILL do damage. You can force the zerk fitting out, and damage the bearing seals.

I can certainly put the new one in myself, but I still would be a little concerned about the overall health of the turbo since its had 700 plus miles put on it with no idea when it fell off. Was it not torqued down properly in the first place? what is the torque spec they recommend?, are these prone to falling out and should be checked every trip? Is there a high temp loctite that should be used? Should the turbo be sent to Comp for inspection?

I just want to make sure every little thing gets smoothed out with the Comp turbo's. So far its been great but I can only imagine that if this were to fall out and someone not catch it in time that it could severely damage the turbo and possibly someones engine when it lets go. I would be curious on Comp's response on how bad not having this fitting in the turbo would be since the grease leaks out without it.

Thanks for checking in with them Sasha:tup:

Just to clarify for the thread so this doesn't become a "installation error or greasing error or user error thing " I have not even opened the grease, grease gun or grease gun hose. I have not greased this turbo yet and the zerk fitting just fell out at some point in time just driving the car.

I'm just giving you a heads up on greasing. :D

A press fit zerk fitting is not screwed into place. As there are no threads. So there are no torque specs. You have to either press them in, or beat them in. I have used a socket, extension and a hammer to tap them in place.

Problem you may have is a slightly bigger hole then what is called for. Or the zerk was undersized. One is the reason why the zerk fell out.

The zerk is threaded into the stem, and the stem is threaded into the center section. Nothing is pressed in.

OP, I will check with COMP on the torque spec, and other things mentioned.

I was going by on what you had said earlier. About them being pressed in. And no threads in the hole.
