Comp turbo failure less than a mile

jwick

You left out the $20k it costs. That's a huge factor.

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.

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.

Happy wife........happy life.

It's better to ask for forgiveness, then to ask for permission.

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