CONTINUED FROM PREVIOUS THREAD https://my350z.com/forum/forced-indu...mance-kit.html NEW ISSUE,,

Precision warrantied the turbo, but problems continue and I am sick to my stomach at this point now.

So build # 2 down the drain, sounds as though a bearing is ready to go or gone, car was fine for a 2 hour drive to MTL for a session at icar, drove it all the way back home without any issue, checked the oil in the a.m. was down a half liter, topped it up and started the car, sat as per normal at idle to bring it to temp and 1 min in i hear this awful noise like someone dropped a hand full marbles in the motor, knocked around for a few seconds so I shut it down...WTF!

Started it up again and the car was idling fine, when reving the motor the knocking is moderate but definitely there with the revolution of the motor. Funny thing is at idle, you can almost not even hear a thing???? Thoughts???

Within a year the stock motor toasted tahnks to a **** tune from almassi tuning, then build #1 from R/T tuning blew up due to the incorrect head studs being used, that left the block useless and now build #2 that was supposed to be "bullet proof" has sit the bed for no good reason at all.

Afr's 11.2-11.7 @ WOT we even de-tuned the car down to 566hp from 648hp to be sure it would last...hog wash, not even 2000 hard Kms on the thing and know this?? I am on the fence on if I should bring it back to R/T for another build or just part the thing out and forget about this ****. 30k in 12 months through a stock motor and 2 builds from a reputable shop and still left with nothing but S H I T.

Is there anyone....ANYONE !!!!! Running a built and boosted Z ( BP kit or other) that does track days( road race) and has had any success, if so, where did you get your motor built...I am starting to build some skepticism since building a motor is to reinforce it not to have it ****ing blow up after a few km's again and again and again... so at this rate Im handing over 8k-15k to the builder every 3 months...does this sound right to anyone?????

 

From my experience, (4 engine from different builders in two years)

Don't rebuild it. VQ are not meant to be boosted. Even if the next engine hold up for some time, you will always have that fear of blowing it up and that will keep you from enjoying the car.

My advice:

Part out everything, do an engine swap or sell the car and buy an EVO for the track days.

 

I think I'm going to a s2000 when I go boost is the new conclusion I was going to do a BP or SFR Twin but with the F20/22 motors being bulletproof from the factory its hard to resist.

 

Sorry to hear about your troubles OP. If I was you I would stay N/A when road racing. Its tough to keep an F/I car cool on the track. Especially one not built originally for it.

 

theres plenty of people out there who dont have issues, like ive said from our previous conversations ive built my engine myself and push it hard(not atm since waiting on software but when i drive it), contrary to midz's comment there is nothing magical about the vq that makes it so its not to ment to be boosted thats a comment from someone who really has no idea on how to build anything. if a shop is having issues building the vq35 they will have issues with any engine, some engines might be a little more forgiving due to say iron block because they expand less then aluminum but that just shows the shop has no idea what they are doing and cannot account for such things, they are pretty much just throwing parts together and hoping it will work. ive said it before and ill say it again i would put the rest of the money i make the rest of my life that 95% of vq busted engines is 100% the tuner or the engine builders fault and has absolutely nothing to do with the engine family, a engine is a engine.

im not one to pay to do something but if i were to pay someone other then myself to do something(afterall i dont own a shop lol at least not yet) it would only be sound performance, dynosty, or vinny ten racing. those 3 have shown that they know what they are doing across multiple platforms and show results. i can tell you from dealing directly with dynosty i have no complaints, can also tell you dealing with vinny ten a little he is very opinionated. he wouldnt build me a engine just because i told him i would definitely be running meth on the street for more power on a street tune.

think we discussed it before but you were running a ati or a fluidamper correct?

 

Some people have pushed the stock block to +500whp. Is that the normal? hell no. some people get lucky with the VQ. A lot of people is doing engine swap for a reason!!

People have blown VQ's from most if not all of the "successful" engine builders in this form.

OP, Just search "blown VQ35" and see for yourself. Or better yet contact Cass or Alberto and ask them how many engine they have blown (each of them tried different builders and it still blow up.

 

Idk about cass but I know of 2 berto used and umm not the ones listed. I know my shop of choice gets their engines from dynosty. What about IPP? Also heard great things besides drama from VTR

 

Me and couple of my friends tried IPP. We all spun bearings.

Will any of the above (sound performance, dynosty and vinny ten racing) guarantee their engines?

I know some VR38 engine builders do.

 

I would just do an LS swap for trackday use

 

Really, a LOT of people?
List 10 names of people with a successful finished swap.



gix, sorry to hear about the problems. Sounds like a part failure which is a quality control issue. No part ever put on the market has a zero problem rate in it's entire life. There are always parts that fail brand new due to a manufacturing defect.

 

getting a engine from a builder that is known to be 50/50 and it not blowing is lucky, buying a engine from a builder that dosnt have the engines blown and it not blowing is expected. please know wtf your talking about, show me a blown vtr, dynosty or SP engine? intense power, forged, gtm, ipp, list one of other shitty builders here are not "successful" they are simply companys that talk good ******** and people are stupid enough to believe them and keep going back.

those are referred to as bubble shops and they arnt a place you should be taking your business as i said you take it to a place that has shown to know what they are doing across multiple platforms. ive already show you dont know wtf your talking about multiple times so you should just quit throwing your bad experience out there like there is something special about the VQ that makes it blow. how about you actually do some research of your own and you will see those "successful" bubble shops blow engines no matter what they are even your precious 2jz.

op please do search blown engines you will see a bunch from other builders but wont find any from those 3 listed. personally i would go to hal at dynosty myself ive had a great experience with them as has everyone else who deals with them.

alberto went to forged initially how about you go look at some of there work across other platforms, i suppose GTR's arnt supposed to be modified either right? because they have done **** work on those too.

cass went REPEATEDLY to the EXACT same engine builder, despite being told several times to switch it up. the definition of insanity is doing the exact same thing over and over again and expecting a different result. theres a reason VTR, dynosty and SP are known across multiple platforms.

 

saying and doing are completely different things go ahead and get one of those "guaranteed" engines and try to warranty it good luck with that LOL all the machinists guarantee there engines from machining defects, not accounting for additional expansion of aluminum, not going with the correct spec bearings for the power level, ect is not machining defects. machining defects would be a rough spot in a cylinder wall because the cutter skipped.

even IF you can actually get someone to warranty an after market engine, only way it will happen is if you run it EXACTLY how they set it up and they do 100% of the work including tuning. NRE does 3 years 30k warranty's on there engines from the exact same thing, think they are going to warranty the engine if you swap turbos and run more power then it left them from? exactly.

 

pf supercars didnt actually build him a engine though did they? thought they just tryed to fix what forged screwed up and coulda swore i read he was happy with what they helped him with(course could be wrong just trying to go off memory)

 

I have a few customers that have Dynosty built engines, and they are all going strong with no issues to report. I know for a fact that my very fist customer (Don) MI35th is very hard on his engine and participates in a lot of road course, drag and shootout type of events. All the work done to his car was done by one shop, Dynosty.

 

You wanna play this game?


List 10 names of people with 1000whp VQ's.

 

SP did blow their own shop VQ but they kept quit about it just like the others.

I dare any of your beloved shops to come to this thread and say that they haven't blow a VQ before.

Also just because YOU think you are right does not meant its true.

 

According to who? you?

You were not even talking about the same thing I wrote.

And I see you keep personal attacking me every time.

 

list 10 people you actually know with 1000 hp of ANY engine its not a common thing.

 

and you know this how? report, video? exactly your not even in the country so stfu, every time you come out with some absolute ******** and after your are shown proof contrary to what you say instead of coming out with some ***** and saying "oh **** i was wrong" you just vanish. dude really just stop people like you are the worst ****ing thing for the the industry ****ing check book tuners who pretend like they do there own **** and talk like they know wtf they are talking about when in fact they dont have a clue. so just stop, FIND me one that blew up, show me proof of 1 that blew, and SP's engine was making FAR more then this guys engine for FAR longer, even 2JZ's blow at over 1200 hp.

your last engine was a IPP engine right? so why the **** would you go buy a engine that has documented issues with improper decking of blocks causing piston to deck distance to be different between front and back cylinders, known to have spun bearing issues, and KNOWN they dont even build there own engines they subcontract the work out to someone else. its your own damn fault you had issues, has nothing to do with the engine, would have had the same EXACT issue if it was a vg30, 2jz, rb26, or lsx having **** work done results in **** outcomes.

 

really you mentioned how the vq was a **** engine vs the 2jz i posted dynos that proved you wrong, you commented about how the RB had the same power curve as a 2jz, again i posted a dyno proving your a idiot. every time i prove you wrong with ACTUAL tests you just vanish or pretend like it dosnt exist.

guess what your OPINION on how the vq is a crap engine dosnt mean ****, actual testing shows different and that you have no damn clue what your talking about. engines dont magically just blow up because they are a certain engine family they blow up because something goes wrong. last ive checked ive actually built engines and not one has spun a bearing meanwhile you keep having "buddys" help you and paying **** shops instead of flying someone who actually knows what they are doing out to you. you have 0 credibility because you havnt done ****.

THATS why it goes to personal attacks because your stupid *** goes on and on about **** that you really have no idea on how its done and repeatedly try and tell people WHO ACTUALLY BUILD **** they are wrong, when you have built anything then come talk, till then lurk and stfu

i suppose your first engine blowing on a **** box tune on a turbo kit that is known to have issues and **** support is also the magical force that orders all vq's to right? or how i have more miles on my SINGLE engine then cass had on all his built engines combined despite the fact that i built my **** in a driveway, magic right? i used the force on that **** to make it not blow up.

ignore the fact i have built SEVERAL high power engines before and know what it takes to not spin bearings, ignore the fact that bearings ONLY spin from dirt, det/pre ignition, too small a clearance for the power going, or too large a clearance for the thickness oil being used. ignore the fact that 95% of those engines with spun bearings are rocking stock like clearances, despite the fact that the bearing journals are bigger then almost all domestic v8's which require almost DOUBLE the clearance of what those engines were being built with, ignore the fact dumbasses are notorious for going with lightweight pulleys and providing nothing to absorb harmonics of a engine despite a v6 being the most out of balance engine produced and NEED that absorption more then anything.


tell you what, the old school generation 1 small block chevy is WELL known for being a bad *** that can handle abuse and go forever, go try and build a 800 whp sbc 350 with 20 thous clearances on the journals(which requires a smaller clearance then the vq35 both due to journal diameter as well as iron which expands less) and tell me how that turns out for you. the journals are HUGE on the vq35, if a shop dosnt actually know what they are doing like 95% of the people building vq's then of course they are going to blow up. thats the owners own fault for being a dumbass and trying to take it someplace because it was cheaper, theres a reason its cheaper. thats the EXACT problem you had, you tryed to cheap out because IPP had the cheapest engines and you suffered for it then blamed the engine instead of the dumbass signing the check.

dont like it? to bad, ive built more cars in the past 2 years then you have in your life, thats not even talking about the domestics i used to build, theres a reason i can just hop in the import world and be able to build cars without them blowing up.


if you were to take some of the absolute BS that you say to some of the more reputable forums the the turbo forums you would be completely ignored or laughed out of there, why i spend more time there then here anymore, this forums is literally barely above nico club at this point
