Tonyzs/c03 build thread
 

Well I figure its about time to start my build thread... Its been a very long and complicated road, but I think that I'm seeing light at the end of the tunnel, its either that or the oncoming train :gotowned:

I bought the car with a Vortech V-2 supercharger on it and immediately added larger injectors, fuel pump, smaller pulley, and a Utec. It was a blast to drive, untill the motor blew :( but I was about to head off on deployment so I figured that it was time to go for broke and do a full build and twins. The car spent almost two years in the shop, I had several headaches with them and ultimately the car was "finished" according to them and I went to have it tuned and broke a cam :mad:. Had them fix that problem only to put the car on the Dyno again and the oil pump failed and toasted my turbos :mad:. So rather than take it back again and wait for them to get their poop in a pile I decided that I would take matters into my own hands and tear it down in my garage, at least that way if things take a long time then I know why, and I wouldn't be lied to about the progress.

So I backed her into the garage and put her on jack stands and got to work. It didn't take very long to get the motor out and the turbos off. I'm now waiting on the turbos to come back, I picked up the new oil pump yesterday along with a new power steering pump too. I'll update this as I get the parts back and get everything put back together. Thanks for takin a look everyone.

Tony

Good luck with your build. Sorry to hear about the issues you had with your shop...

Good luck with the build. Post up pics along the way.

i agree w several sentences in this.. especially about BS progress reports.

:( IM getting frustrated again w my build. Even after shaking hands w the owner that id get weekly progress reports after all the BS i went thru.. good ol disappearing act again.

Props to grabbing the reigns yourself man. Thats maning up..... like a soldier for sure.
thumbs up.

Good for u, the only way is do it urself!

May I ask Wat oil pump failed n Wat did u replace it with....

Oem de, rev up, Nismo etc....?

what was the shop involved in the initial errors?

How does an oil pump fail?

When the pump failed, did you spin a main? Did you have the block, heads, cams and turbos all checked after the pump failure?

Kudos on taking matters into your own hands. I know what its like doing a teardown on stands in the garage, not much fun.

I'm not 100% sure what pump was on the car as I didn't see them put it one the car, but during talks with the owner of the shop I requested that they use an OEM Rev-up pump, which is what i replaced it with...

The shop involved had more than what I posted here...

East Coast Truck and Auto is the shop name

link to the thread about them...
https://my350z.com/forum/mid-atlanti...op-review.html

I did check out the heads, they are good, clearances are a little tight but the heads only have about 50 miles on them. Block still has good cross hatching on the walls and compression is still good. The turbos got fried unfortunately :icon22: but thats being taken care or as i write this.

I'll deff post up more pictures tonight after I finish assembling the long block, thanks for words guys. :thumbup:

THIS SUCKS. I hate it.




But glwb op!

Oil pump failure and the main bearings all lived, lucky :eek:

sorry about your shop troubles but it looks like you are on the right track. Doing it yourself, you can be assured it is right.

hmm, heads and bearings but the ball bearings that are water cooled in the turbos and require very little oil were burnt up.

Sounds fishy to me, like the oil lines were clogged or not properly installed. maybe someone got some crap in the oil restrictors.

yeah, I was thinking that same thing. But when I pulled all the oil lines apart there wasnt anything clogging them :icon14: so to be honest I'm not sure why they failed, the the only thing that makes sence is the oil pump, or the face that there may have been some crushed, or missing o-rings some place in all the oil passages in the block some place...

anybody have a diagrame or is able to explaine the oiling system on the DE's to me so I know how it works, that might help out in figuring out what happened :dunno:

Guess a little back story on that part would help. Got the car back and put it on the dyno and the IVT system want working. My tuner gave everything a once over and said that everything looked fine, but he never pulled the timing covers off or anything, he only checked the electronics and the actuator that on the top of the heads. With that done, we put the car back on the dyno and made another 2 or 3 pulls and he noticed that there was a bit of noise coming from the passanger side turbo so he removed the intake piping and found that the drivers side turbo had seized and the passanger side was making a lot of noise as well, I think that this is wear the luck of my main and rod bearings not eating shiit comes in. Now I know that all of the IVT system is operated by oil pressure and during the process of tear down I did find that I was missing on of the o-rings on the passanger side cam gear cover and that one of the other o-rings on the same side was crushed and torn. So is it wrong of me to think that the oil pump was the culprate in the whole system, I mean I know that the o-rings didnt help, and I have since got the right ones.

There is an oil passage diagram in the service manual.

all i have is the Hanes manual, tried to download the Nissan service manual but the document was password protected :gotowned:

It's 100meg so i can't email you the whole thing but the lubricating system is only 443k so email me at jeffbinder@gmail.com and i'll email you that chapter.

or just download from here.

not PW protected and the 1st link when you type "350z fsm" into google....

:dunno:

yeah I found it about 5 minutes after my last post lol... thanks though guys.

Good news, just got an e-mail from my buddy that is rebuilding the turbos for me and he got them Thursday and started working on them this morning, he said it should be about 7-10 days turn around before he has them back in the mail (priority this time :thumbup:) then its all back together and back in the car and to the tuner :)

Got the tracking number for the turbo's on Wednesday :thumbup: I should have them tomorrow or Monday at the latest.

He also e-mailed me to let me know what happened to the old turbos... who ever put them on the first time used some sort of silicone to seal up the oil lines and it eventually worked its way into the bearings and fried them...

I was climbing walls after 6 months I couldn't imagine 2 years- and then to burn out the turbos on account of what I'm assuming is pretty jank worksmanship.

Good luck with the rebuild and I certainly respect that you had the balls to do it yourself.

Dude, the FedEx guy is making my climb the walls :icon11: they tried to deliver them last night and I wasn't home.... FML... now I have to wait him out today lol

So I've been pretty busy with work and trying finish up the car. I did however get a final answer on what killed my turbos... the bearings don't work so well and tend to fail when they are full of silicone... With that information I ripped everything apart again to make sure that there was no residual left in any of the oil passages and flushed them all out. Now I'm waiting to get a spacer machined to step my drivers side turbo off the manifold so that it fits flush, once thats done I'll be seeing the light at the end of the tunnel, that or I'll finally run into that oncoming car haha.

So instead of starting a new post I figured that I would post here. I started the car last night :thumbup: I have a small coolant leak that I need to track down but I have a question about oil pressure and the HR oil pumps. After starting the car my oil pressure gauge was reading ~ 60psi it was coming down as the car warmed up but I know that we sould be at about 14 or so psi, just wondering in this is normal or if I should be looking for some sort of blockage... I did look over everything before dumping the motor back in and all the oil passages were clear. I'm running 10W-30 Mobil 1 synthetic if it helps any.

i think i would crap myself if i ever saw 14psi oil pressure

service manual calls for ~14psi at idle though :dunno:

i've never seen less than 30psi on my 40 or 50 weight oil. maybe if you were running 30 weight oil.

ie: you have no problems with your car

i run 5-40 shell rotella and see mid 20's at idle when it's fully warmed.

I use a defi oil pressure gauge though. No stock gauge on g35

So its been a while since I posted an update to this... something about work getting in the way :icon38:

the car is done now... well sort of, still some things that can always be done, you know like bigger cams, more boost, most suspension parts, etc.

Long story short, I had the guys over at SOHO finish off the block and tune the car for me. At that point the car 450hp/500tq. When I had the turbos rebuilt my buddy didnt have any spare exhaust housings because the old ones got torn up, so we stuffed the old 2871 wheels into a set of machined GT25 housing. As you can imagine I was running out of ass up top, so i decided to upgrade.

Purchased a set of the new GTX2867's :thumbup:

With a re-tune and some bigger injectors and pump the car now makes 603hp/602tq :cool: car is a riot to drive and to be honest, a handful if I get caught in the rain.

Future plans include some more suspension work, new wheels, and more power in the form of some new heads/cams...

sweet! glad you got it finished up. Did Nik tune it?

yeah, they also used to car to mock up their new true dual exhaust. :thumbup:

congrats on a nice build...hope you are driving it and enjoying its and its not just a garage queen man (other than weather related ::dunno:: :)

Nice! Nik and soho are badass. Didnt know they are selling an exhaust now..thats awesome. Their fabricator made an awesome exhaust from scratch for me a year ago, very high quality. They are definitely doing great work:icon38:

Thought I reconized the car! The exhaust is pretty bad ass and sounds great wot! I was one of the first to get it after you.

Yeah man, she gets driven a lot haha, wouldn't say that it's a "daily" but it gets driven enough that she due for an oil change after only 4 months haha

You don't need new head/cams for more power. Those GTX2867 turbos are good for close to 30 psi. Invest in a Haltech with flex fuel, put in some e85 and crank them up. :-) I am injector limited with ID1300cc and 820 whp DJ (at 22-24 psi on e85).

e85 where i'm at is not an option really... there is only like one station in a 50mi radius or I would :suicide: also injector limited to ID1000's (my cams are itty bitty too lol 256/264)

pretty impressed with your numbers though, I'd be more than happy with those... needz more power for sleeper status lol
