Can you elaborate anymore on the 3qt accusump and oil filter relocation kit? I'm guessing that is going to combat the oil starvation issue.

Thanks

the accusump is one line plumbed into the pressure side and is basically an air spring cylinder so as preussure comes up it fills the accusump with oil and as it comes down the accusump will discharge to slow the rate of pressure drop in the oil galley for a short time.

It's also called the poor man's dry sump system. It serves two purposes, pressurizes the system on start up and also maintain pressure for a short period of time when the car loses pressure (due to bad pickup).

Great news! Car is tuned.

Bad news. Stock Nismo exhaust is holding the car back. The Nismo S tune exhaust is different on the 350, its a single 3" with a good amount of baffling in the muffler.

Big Thanks to Bobby and VSR for working into the night getting the car together. Its been a great journey so far and its far from over.

There are a few more loose ends to pick up before the car can be shipped back. Regardless, I am siked to get the car back.

Of course, rough result:

6 psi = 380 whp
8 psi = 420 whp
13 psi = 500 whp

Don't have torque figures, but im sure its way more than the 260 lb-ft I had before. Again, the stock exhaust seems to be holding a good bit of that power back. Glad Bobby and VSR built that block. Once I put my big boy pants on, maybe I'll "invest" in a more free flowing exhaust and really unleash the single turbo's potential.

Next steps include a shake down to get all of the bugs out, data log to refine any potential rough spots, throw some larger tires on the car, and just enjoy my first car out of college as it should have came out of the factory

I'll post up dyno's when I get them.

A little honeymoon reflection (still early and i'll update as I go forward):
IMO, the true value in a performance shop is how they handle "incidents" as incidents will inevitably arise. Every shop has their oopies, more importantly though, Bobby has made right their oopies (based on the threads i've read on 370z). I hope my story is free of incidents, but knowing that Bobby will come through regardless really settles the mind.

Nice numbers! Post your dyno sheet if you can get it. It does sound like the exhaust is holding you back especially on the high boost map. Can you not get Bobby to fab up a free flowing one to mate to their downpipe?

Bobby did offer to put on another exhaust but I declined. I really enjoyed the exhaust tune of the Nismo when I was NA.

Im sure the car sounds different now but I'd like to hear myself before going down another road. On that note, to retain the VSR warranty, I am not to change the tune or exhaust, so I'll be running these power levels for awhile.

How much boost???

A healthy 13psi. :tup:

You should post up those pics of your car that VSR took. They're on the facebook page.

incorrect...

Car on its way back!

That's nice. Reminds me of the old powerlab systems. Bet that power band is crazy. Gratzs

Nice dude. One thing to think about is finding a way to get a front strut bar that fits now. I'm sure you will feel a big difference on how she handles curves now in a negative way.

Would be good to see the numbers this thing can put down when you upgrade exhaust. Enjoy the ride!

I am not sure if it will be THAT big of a difference, but only time will tell.

Finding or creating a new front strut bar is going to be a challenge, no doubt.

Here is one potential option

Another option is to fab something that mimics the new M4 strut bar

7 months update:

I've driven ~700 miles, most of which have been a love hate relationship. First and foremost, the car is MUCH MUCH faster than when it went down to FL. All I have to say is, I should have boosted the car much sooner. I've never been a man of words, but the feeling is simply amazing.

Now for the bad, It started on the first day with a bunch of small things and has eventually escalated to getting the car fixed somewhere else. I knew things were going to be rough given the nature of the work so I had low expectations to begin with. (not a reflection of VSR but more so of an understanding that boosting a NA car is not easy and will fail in one way or another).

Bobby was extremely helpful at the beginning with flying up and fixing some of the issues but the car still isn't right. From what I've noticed with the quality of work and the litter of issues; I just don't have the confidence or trust anymore to send the car back. It seem to me that there were more items at play that affected the service (Bobby's spin off may be related but im speculating here) From what was conveyed to me, the car bounced around different techs (which I assumed to have different skill levels and different levels of commitment). However, the welds look great! For the welder to have broken his leg to come back and work on the car while in a wheelchair is simply astounding.

Now the laundry list of things: sigh...
- Radio wasn't seated back (granted, I had a rats nest back there but I got it to fit w/o shorting)
- Car misfired in bank 6 around 4k rpm (replaced injectors seem to fixed it)
- Couldn't turn over in colder temperatures without multiple cranks (FL is a sunny 70 when tuned)
- Bunch of missing bumper/fender clips along with an utterly destroyed undertray
- PCV return on intake manifold was cracked which most likely contributed to rough idle and misfires. I found a bunch of oil on the back side of the intake manifold so I added a catch can.
- Bunch of small vaccum/boost leaks everywhere (varying sized hoses and T's used to route boost lines)
- 2 bolts on transmission bell housing that secure the transmission to the engine block were floating and not torqued down
- Cross pipe from driver side headers to up-pipe was not heat wrapped (seems like a silly thing not to do since the exhaust pipe sat 1" away from transmission)
- Bunch of small items went missing and I had to reorder and overnight them (i'll leave it at that)
- Bunch of gauges I ordered didn't seem to work even though they were brand new? (I guess AEM LEDs blow out often)
- Car was missing 2.5qt of oil and 1/2 gallon of radiator fluid when delivered
- Tank cover over fuel pump left floating
- Fuel regulator secured to firewall with 1 screw
- Clutch wasn't bled properly and 2/3 of the pedal was dead. It was damn impossible to get the car into gear without smashing the clutch pedal. (I replaced it with a Tilton MC and SS lines)
- Lower transmission cover, clutch line cover missing
- PS line seem to sweat and needed replacement
- Sandwich plate plug needed tightening
- Sweet looking crash bar held onto frame rail with 2 bolts on either side instead of the 4 that exist


VSR fixed some of these issues when Bobbby flew up but there are still a bunch of items that I've been discovering and struggling to fix. The reality is, I really don't have time to correct the issues anymore so off to another shop.


My Retrospective:
It has been an interesting journey and one that I knew that was going to face some challenges. My expectations was to get a 'fast' car. Did I know there were going to be issues? Yes. Did I know it was going to take this long? Nope. There were plenty of things that could have gone better and things that I could have done to help facilitate the process. Were there things that VSR could have done better? Absolutely. Was I pissed at all of the BS that was wrong? Yup but Im over it and moving on. When **** goes wrong, you gotta realign your expectations. My expectations was to receive a fast toy and I think too many people have unrealistic expectations thinking everything will be perfect. A car has thousands of parts, its unrealistic to think everything will be done perfectly.


Future:
Locale really made things more difficult with interfacing with VSR, so i picked a local shop around here. Its a few miles down the road with a much smaller web presence, at least with Nissans. Certainly there will be challenges with the new shop but I will be sure to take some of the lessons learn with my previous experience forward to ensure things go a little smoother.


- recirculate the wastegate back into the exhaust
- replace Nismo exhaust with Motordyne TDX2
- throw in more Cats because smelling like gasoline at work sucks
- retune it for new exhaust, VA and not sure why boost comes in so late for a 6266 but being kicked in the pants is fun on the street but terrible at the track.


::cross fingers::

Man, that sucks that you had such appropriate expectations going in with eyes open and still managed to have a bad experience :thumbsdown:

Kudos to you for having the right attitude now, and good luck finishing up the build :tiphat:

Maybe some :pics:

did they install your clutch as well?

:iagree:

These experiences are exactly why I like doing all the work myself. That way I know exactly what was done and DIYing also give you a leg up when troubleshooting.

So when I bought my house last year, I tried to find a place with a larger garage to take on a project like this. I even bought quick jack to help.

Boy was I wrong about taking on a project myself. I bought the house, had my second kid, and took on a new role at work. Now I barely have time to eat and take a piss.

Once the kids are old enough to turn a wrench, i'll have them help with another project. Maybe a miata or something that they can enjoy as a learner vehicle.

Down the road, when the Z eventually blows up (hope not, but **** happens). I'll buy something already boosted (STi, M3) and enjoy that until my days frees up.

:tup::eek2::eek2::eek2:

Sorry to hear this this, it's sadness me that shops do this. It was awesome that the man in the wheelchair showed up to help, but look at all the stuff that went wrong.

Our cars is like our kids you want the best for them no matter the cost. If I'm paying full cost for my car to be worked on I shall never sent on a gamble. That's why I speak to Z1, not trying to be a fanboy just stating what works for me.

I'd would get the locate shop to fix, and re-assemble the car. Double check behind every move, than get Jon at Z1 to do a turn key tune using data logs.

Won't even take the chance of doing it any other way.

Good luck hope it works out for you.

:iagree:

Purchasing a boosted Z will always be the best route depending on who did the work, and how it was taken care of.

EX: If I ever decide to sell, who ever is the lucky bastered to purchase my whip will have EVERY dime spend on it in a neat binder. Dates, amount, and contacts on who did the work.

You're an engineer, aren't you:tup:

:bowrofl::bowrofl::bowrofl:

Best laid plans...:rofl2:

Guess you can put it that way.;)

Looks just like my whip, but I have the GTM 3inch cans in the rear.

Looks good !

how'd you route the motordyne up to the turbo piping, custom midpipe?

damm wtf that is some sh*t,
Such lack of attention to details, i dont know how vsr lets any cars leave their shop in that condition. Hope you get it all sorted out bro, if you want i can give you my shops contact.

Some pretty pipes you have there! But are there no tips?

I know every build has setbacks, but to have issues due to lack of attention and care for the details is quite disheartening. Sure your car is fast now, but what happens when an undocumented issue or untorqued bolts comes off when you are driving your car hard?

Hopefully you have had all the kinks worked out and your new shop has double checked everything since you have changed your exhaust! :driving:

wastegate recirculated back into the downpipe after the cat

I'll take a pic when its all done.

tips just weren't put on... they are still working on some stuff.

yes, I asked them to review the car and give recommendations. Car will need another tune and a shake down.

Some more awesome exhaust work attached

Car sill needs:
UpRev GT MAF x2
CJM Stage 1 Fuel Return

Sigh... It never ends

how do you like the sound after recirculating the wastegate?

OR perhaps consider the HR S1-S or S2 kits that will be released next week featuring our new HR billet rails ;)

Those looks super sexy Mr Phunk :tup:

I believe the shop already ordered these. They told me they ordered them Friday of last week.

Haven't been back to the shop to hear it. Car still needs rails and mafs and tune.

OH its those guys, I know who youre talking about. They ordered them before I even had them back from anodizing. I got 3 sets back yesterday in blue, and have some in black coming next week.
