Comp turbo failure less than a mile

solidus

Bruh you don't just give up like that. Your luck is'nt the worst to be had. First my intercooler mount's were wrong, then I got the wrong compressor cover, then my transmission harness melted on the dyno. I had a fuel leak at the hard line and then on the day I finally got my car tuned it was spiking to 16psi so the tuner refused to tune it past wastegate. All that seem bad enough? Well I was so proud of my 509rwhp I decided to boost the hell out of it not 24hrs after being tuned. That did'nt work out so well because it spiked at 23psi right before the pistons, rods and valves turned into oil pan glitter. And all this was on a 2015 Nismo. Today that bastard is running strong as hell at 9psi and very shortly it'll be sporting a built longblock with stage 2 cams. We will all at some point have "Boosted People Problems" but that's all part of being able to say "I made this work." Don't give up man, just build the car you had in your head before you bought the first part,

I love how the alternative to a 500+whp boosted Z is "a sweet minivan".

I updated the 1st post to show that post #79 and #82 will have further explanation on how this was a install error and not a manufacturing defect.


I think I am going to take a little break from the car and focus on work, I knew I was on borrowed time with the stock block but I may end up just putting a whole new one in. I have been speaking with RJM about building a complete turn key closed deck engine and then just sending my car to a well known shop for install and tune along with some other goodies. I just need to talk myself off the ledge about selling the car and buying a used (holds finger quotes in air) Minivan is what I told my wife.....lol but actually getting a GTR as this would be a whole other set of problems and issues that I wouldn't want with a 70k used vehicle...

Prior to the engine being fed metal I had
Compression Cylinders #1. 185 #2. 175 #3. 175 #4. 175 #5. 180 #6. 175
Leak Down % 15% 18% 22% 25% 18% 15%

The leak down I think already wrote this motors fate of being replaced................now with the metal dust.....kind of seals the deal. The last thing I want to happen though is to dump an additional 10k + on top of what I have already put in just to have something go wrong with my new engine if I end up getting one................I keep hearing stories of boosted Z's getting the piss run out of them with no issues at all.......I would like to be one of these people lol.

Having been around racing motors and such. If this was me. What I would do is get the intercooler cleaned out. Take all of the inlet piping off and clean it out. Remove the inlet manifolds and clean them out. Reassemble everything. And enjoy driving a boosted Z. Aluminum flakes passing through the motor won't do much. The heat from combustion will burn them up, and split what remains out the exhaust. I've seen motors take in a lot worse and keep on going.

The thing that concerns me at this point if I decide to keep running the stock block after cleaning everything..............from what I have been told is that there is a chance if or when the stock block lets go I could end up damaging the turbo? I always thought worst case scenario I throw a rod through the block and boom thats it just buy another motor. Does anyone have any insight on a worst case scenario if the stock block takes a S#!t do I risk damaging the turbo.....I am not fond of buying multiple turbos and intercoolers right now.

The last one I remember was Nik@Sohomotorsports,
Give him a cat& ask; as he's very friendly to speak with.
Also: for the compression/leak down test....Forced induction will seal that up- it's not necessarily a bad thing to have a bit of clearance in there.
Don't burn yourself out; we've all been there with some sorta issues with either the Z's or something different.
A little time away to clear your thoughts could be good.

Why absolutely! When my motor took a poop one of the first things I saw in the exhaust manifold was pieces of metal. Interestingly enough they were also in the downpipe. They did'nt kill the turbo but they broke pieces off of the turbine wheel and killed my exapump. The turbo would still boost but it was'nt what it was supposed to be. The fix was to do a rebuild and replace the turbine wheel with a new balanced wheel.

etx

I popped 3 cylinders at once on my 03 350z with a greddy kit back in the day. Turbos and everything else was fine. Just had to replace one valve, build a forged block and replace the upper oil pan. Thing was solid AF after the build.

Every grenade is different tho. I just boosted my 370 and I'm already planning the rebuild cause I know it's going to happen at some point.

Well unfortunately me and the wife have some disagreements about my hobby and where I was planning on going with it. I will be selling and parting out everything I have. The turbo kit will come with a brand new turbo and brand new intercooler 0 miles on them to avoid any metal dust concerns, rest of the kit has 2.5 miles on it. I will start disassembly soon and will update this thread when everything is posted in the classifieds.

Jayhovah

Heartbreaking. My condolences. I hope you get the sweetest of minivans.

Damn!! Sorry to hear that. I've been in your boat and I completely understand. Some things I do I wage a savage disinformation campaign on. My engine popping is still refuted to be damaged spark plugs in some wine drinking circles brought on by me refusing to listen to the GF when she told me something smelled like gas in the garage allegedly.

Rusty

Bummer. I've bee in that boat too with the first wife. Second wife has been great. Long as the bills are paid, and I keep her happy.
