On a built motor I would you hope you guys are getting at least 50k miles out them!! Anything less and it seems pointless to me...

Im hoping for 400whp with my HX40 setup and I PRAY its reliable...

Only time will tell....

 

I just want to see people with built motors with mileage post and respond to the items listed. Only motors that are still alive. I don't care about hearing about broken crap. We see those already.

 

Pardon my error O Great and Infallible Alberto. How dare I, a mere mortal, post in a thread you have already discredited.

Jebus.....

 

I'll be honest... Alberto speaks the truth. My build is on a non daily that might see little track time, maybe once or twice a year.

 

You guys want too much POWA!

 

Not possible.

 

* crickets *

You would be AMAZED how few there are and how little the ones that are living get driven and the even smaller number of those that get driven hard.

In my experience, some shops do hero pulls on the dyno for a cool sheet to brag about, then dial back the car before the customer gets it. My car always left with the max whp it made. I built it to drive hard and did so every time it left the garage. It lasted about 5 seconds every time.

The line up of who has lost built engines reads like a who's who of the F/I top 50 list. Several of us lost builds before they even made it off the dyno.

 

Please clarify: It lasted about 5 seconds every time.

 

i drive mine like a grandma 95% of the time. Believe me, after losing a built motor, it will really change your goals and perspectives and the way you drive. I could give 2 ***** about making 1k like I did on my 1st build. Even at where I keep my boost controller, that still exceeds the amount of ***** I have to stay in it.

On this new motor, I've got about 100 dyno pulls, few passes at the airstrip, some highway pulls and about 7k miles. I run Blackstone analysis at every oil change and have sensors to monitor almost everything.

 

str8 that's torture.

The closer and closer I get to finishing this build, the more and more I wish I had gone 2j.

 

You wanted running stories, not failed engines. I went through 5 built motors with various components (bearings, pistons, rods, heads, cams).

#1 - bought it used from marketplace and was scammed, never saw use

#2 - rebuilt it used engine - lasted 1 dyno pull

#3 - spun a bearing on day I was to pick it up from the shop - 100 miles

#4 - made it to airstrip event, spun a bearing 2 days after ZdayZ - ~3K miles

#5 - spun bearing after 1 month - ~2K miles

You can have an opinion on the shop(s) that were involved (Function Tuned, Hills Garage, Diebold Autosport and Justice Racing), but those same shops are turning out high whp VQ builds to this day that are still on the street.

#6 - LS2 Swap - 3K miles so far and I beat on it every time it leaves the garage

Here's a small sample of people that have lost builds:
Me (5)
Mid350Z (2 or 3)
Alberto
Abushong
Binder (I think)
rrmedix
XKR
Sylvan Lake (2)
Romey
str8dum1
Blackbird

Feel free to chime in with others.

I'm sure there are many more still that were before my time or don't post about their failure so the resale of their kit/car doesn't tank.

 

this always makes me think of going lsx swap

 

Like Str8dum1 said after a few failures you get gun shy, I certainly don't treat V3.0 like the last ones I lowered my goals a fair bit as well. I do hit full boost every time I drive the car though I am a boost junky I can't get enough of full boost runs. I live where most of you would consider "the sticks" I have lots of empty back roads, I often hop in my car and take out just do some pulls and it's not dialed back at all...21psi waste gate springs make sure of that.

 

To the op- I read about your intentions in your other thread and I do understand what you were trying to do here. I actually held some hope that it would fly- sadly it seems too many regulars in here are too bitter and twisted at their own failures (successes?) to give you that satisfaction. you couldn't possibly consider anything other than failure a success around here because if it didn't blow, it didn't go. It's like skiing- if you're not falling, you're not skiing hard enough.

if you didnt blow your built motor taking it 3-4 times beyond what it was designed to hold originally then you suck d1cks for money and you should be killed for not being full of awesome.

There is reality- and then there is this ridiculous harboring of negativity that serves no other purpose than to drag you down into the ditches for fear that you may achieve your "meager" goals while having not pushed the envelope hard enough, or not driven like an asshat often enough to have experienced the failures that bring with it an astonishing degree of entitlement in these forums. To elaborate: you failed to succeed to fail. Yeah. That's what we are dealing with here.

If the only enjoyment some of these guys get out of this platform is destroying anyone else's enjoyment of theirs because they haven't blown up their built motor from either incompetence, ignorance, or pushing some (apparently to them) unachievable limit... I think it's time to move into something different. and yeah- if I blow mine from any of the above I'll be very careful to expect any sympathy in here or anywhere else.

 

the problem with your ENTIRE post is that the people posting did not take there engines too far, they where built with top of the line parts and still failed, most with bearings that is not something that should have happened. pushing it harder then designed would be a distorted bore, snapped rod, melted piston, broken crank. not a spun bearing because it wasnt assembled correctly.

 

From what ive read so far its bearing failure because no one has a science yet for the clearances but like most here are saying you wont know if your build is successful until it shows over time...

 

I know I want to see people's builds with how many miles they've been going. OP, maybe if you just redirect the purpose of this thread by renaming it to "20k miles and boosted club" and then people can share what they have inside. I'm trying to give hope to your idea because I like it....maybe that way the cranky FI owners can leave it alone. Besides, this isn't a scientific research facility where we can only post hard undeniable evidence on why a specific build is successful, it's merely sharing info.

 

So many spun bearings! I agree. With all do respect, I thought spun bearings were due to a flaw in the assembly and clearancing.

 

I do know of a few 'built' setups in my area still on their 1st built engine for years now. A couple of them are pushed pretty hard. It's interesting to talk to them because they went into these builds without knowing about all the failures on the forum, or even having lost a stock block... they built the engines in the name of safety and NOT having to worry... exact opposite of here. I guess ignorance is bliss

 

That is interesting...I still think there are a ton of built motors that we don't hear about running around because they have never come on here and posted an issue.. This is actually a pretty small group. Like if you go to ZNationals, there are TONS of cars with built motor setups. At this point I don't care about driving habits, I just want to hear how long some built setups have survived.
