700hp twin turbo project

Streetz · 03-09-2016, 01:29 PM

I used stock Bearings in my built Vq35de. I Just replaced them last year because I thought after 60k miles and 10 years they would be worn. Pulled them out and they looked brand new. Still had the marks on the bearing material from where we measured them. Car has seen some high power too. I was really impressed with how they were holding up.

I finally had some time to get the old motor torn apart. Holy ****.

While taking the accessories and wiring harness off the engine kept spitting goodies at us (Mempihs370z) through the hole in the oil pan.

As you can see in the pictures above, things got crazy in there. The water pump had metal shavings hanging out in there. I knew when I took the heads off, there was going to be some carnage. Well behold:

Pistons 2,4,6:

Cylinders 1,3,5:

Close ups:

Needless to say, there isn't much left to keep lol.

That is a truly impressive amount of destruction.

V1H · 03-09-2016, 03:11 PM

Oh my science! What combustile force could split a piston in half and bend that rod
I once melted a hole into my piston (reckless nitrous abuse on a VTEC motor)... But this? Pretty epic. Feel sorry for ur damage m8

Do a root cause analysis. Where do you start at?

What failed first? You can say that the motor ate it's self. It's out to lunch. It hand grenaded.

I believe my first words, after a few expletives, while we were tearing down the engine were "near-complete catastrophic failure."

zguynate · 03-09-2016, 09:42 PM

This thing completely exploded. Part of my wiring harness on the transmission was a little charred too from the fire erupting from underneath my car when it happened lol.

None of the ring lands were broken on the remaining Pistons. None of the Pistons were melted or had any obvious lean damage from what I can tell. The only thing I can think of is either a rod snapped, or one of the rod bolts broke and a chain reaction of sorts happened.

Minor and boring update ahead!:

Man this month has been a learning experience for me. I have always wondered why getting a built motor takes so long. Well I have learned that when you're working on other peoples time, sometimes things don't go as planned.

I picked my motor up from the machine shop. It wasn't balanced because I want to size my bearings and check the clearances myself. I ordered my bearings and paid for 2 day shipping so I could hurry up and get it back to the machine shop for balancing. After some trouble with the shipping dept, I finally got my bearings 11 days later.... Immediately drop off my assembly at the machine shop that has a good reputation. Well 4 days later I get a call saying that they can't balance the crank because they don't have enough bob weights since the crank is a 60 degree v6 crank. I went and picked it up and dropped it off at another machine shop that I should have taken it to in the first place. That was Friday and I was told 2 weeks. We will see. Its getting done slowly but surely.

Its probably not going to be done by ZDayZ. I have a lot to do, and a small window of time to do it. Even after I get it all assembled, I still have to break the engine in and go get it tuned.

With all of that being said, I have learned A LOT about this process, and will probably learn a lot more. This is the most fun I have had working on a car in a while. Not to mention I have purchased some cool tools to add to the toolbox. Win/win.

Hey, can I buy that rod from you? I need a desk top "trophy"! That is awesome!

whiteZ34 · 03-29-2016, 02:20 PM

There's more to this then you're telling us lol. Your car definitely screamed, "Grenada!!!!" Then 5 seconds later went boom.

Rusty · 03-29-2016, 03:10 PM

In my experience. They always run their best before they go BOOM!

Nope. I'm not omitting anything. It was running like a champ until it blew up. The only issues I had out of it were clutch related issues. Nothing motor related prior.

McSpeed · 03-29-2016, 09:16 PM

Carnage!

I plan on keeping it and putting it on a plaque or making it into a "trophy" decorative piece lol.

Turn the block into a coffee table. The crank into a lamp stand. The heads as book ends. The intake as a center piece.
