another dead bbsc car

[4AU4LIFE]

well..I went out to do some 1/4 mile testing and then started hearing a rattling sound..

Took her to install my aem that came a few days later in the mail and they told me that one of the rods is broken and that the horrible sreeching sound is coming from my crank. She will still start and all but she's unsafe to drive since its all gonna come undone at any second..

This happenned to my 91 nsx with the version 2 ss box and the bbsc supercharger..

Happenned around a month ago. Ive just been to heart broken till post till now..

So Im eighter gonna find the cheapest nsx engine I can or Im thinking about the stroker kits out their...

Any info on the stroker kits would be greatly appreciated...How mu ch power with my 5 psi bbsc and my aem would a 3.x stroker kit produce.

How expensive is if for the stroker kit and everything all forged ect.

Thanks for any help on this

Dude, I real sorry to hear about this. :frown: I can totally relate to your feelings right about now. I have been thru this same thing a few years ago with the BBSC. However, I only had to deal with broke ring lands on 4 pistons but all the rods were good and my crank was fine too. So, I know how you feel.
A couple of things different about my situation was that at the time, nobody knew that the SS box was such a piece of crap that it turned out to be. Since the kit was still in it infant stages, it was kindof a learn as you go type situation. And believe me, I learned.
There also weren't tons of people on here telling me that I absolutely must get a different engine management system and telling me that I was crazy if I started/ran the car without one. Sadly, I know for a fact that I myself came on here and thoroughly encouraged you do that immediately. Since you were spending so much $$$ on the car already you needed to do that very quickly. Sadly, that didn't happend.
I can also understand your frustrations over all the expenses you are and have incured since owning the car. I'm sure it has put a bad taste for the car in your mouth. Understandly so.
I think that you are still longing for the thrill of having a modded Viper and all the things you had in the past with them. I for one, think that you probably should just remove the BBSC, sell it, find a used motor, get it installed and sell the car and move back to the Viper.
OR, if you really want to just get out and cut your loses, sell the car as-is and call it a day.
I don't think doing a stroker is going to make you happy. I think getting out of the NSX entirely and moving back to the Viper will.
Best of luck with whatever road you take.

any motor will blow without oil and any fi will blow motor without good tune

 

[lightguy]

what are the design flaws? Aside from it being hard to fill my oil i mean.

How do you go about changing the oil ?

PS; Ive read about blown seals on the Paxton unit, difficulty in aligning the drive shaft properly with bearing replacement, bearing failures, and using a set screw to attach the driveshaft to the Paxton unit instead of a key.
Not trying to be difficult here just trying to accumulate facts before I pull the trigger on a Basch, Honestly.

Well, i'm guess youre asking because you don't know.. I either pay someone to change the oil, which is the usual manner, or I change it myself by using a long narrow funnel. It's not that particularly hard... just irritating because i know how easy it was before the SC was put on. the other method is using that thingy where you pump the oil out of the dipstick tunnel. that's the easiest i think, but it's $60 for the pump.

I've had a bearing failure. 8000 miles. I've got about 30,000 miles on my last bearing. I agree 8000 miles seems a little too soon, but anything with moving parts has a finite life. I do think the "boostzilla" concept with the blower on the other side would eliminate that... but ordering from dali might eliminate my money and not provide a boostzilla.

the set screw, as i understand it.. is just a 3/8" bolt which holds the pulley over a hex-cut shaft. Seems reasonable to me? only issue is if screw backs out and hex cut shaft gets ruined.

 

[Eclipsed]

I've been looking at boosting options, and have read nothing but horror stories about BBSC setups. Think it's on dali racings page the list of engines blown due to that supercharger.

Neither here nor there, but if there is that much negative information about it, i wouldn't have ran it to begin with. just my opinion.

 

[doc_tai]

bad tune blow motor not the bbsc set up or any fi set up

 

[swerve2007]

in all honesty the tread should be renamed- it has nothing to do with bbsc-caused failure.

 

[lightguy]

Thanks for the info persig.
Nothing too scary in it to dissuade me from considering BBSC.

 

[nsxxxtc]

After all the grief let me offer my condolences. No matter what caused your issue, I FEEL YOUR PAIN. Being a victim of the SS myself I think SS and tuning hurt your motor. The detenation probably bent the rood and then!!! I appreciate you posting and if you like the car you will get it sorted out. I have an 02 and a 97 for sale at 49 and 42 respectively both are CTSC if you decide to bail on that one and move to a later model. I am putting a new RPS dual clutch in My BBSC 97 this week. It makes 392HP. The dealership took the car for a ride and hurt the clutch. Good luck with your car. Vipers are nice but if you like to drive fast the NSX is much safer as far as handling high MPH.

. Being a victim of the SS myself I think SS and tuning hurt your motor.

From the way I understood, he never had the car tuned. I might be wrong, but the SS was supposed to be plug and play and there was no tuning involved. The AEM was going to be installed but the engine let go before that happened.
That must've been some serious detonation to break the rods !!!

 

[swerve2007]

no tune will help you if the engine has NO OIL.

 

[CarbonNSX]

Well I guess I have been lucky, I ran the BBSC using the SS for 2 years and I didnt have any problems. I enjoyed the time with my BBSC but I have decided to part out my car and remove all my "show" components such as BBK's, Coilovers, BBSC, Stereo and Monitors, Roll Cage, etc etc ...

I use to show my car in the Hot Import Nights circuit for the 2007 and 2008 seasons. My BBSC probably only saw 8000 miles in those two years because my NSX always needed to be ready for display. My driving habits were conservative however I did have the occasional urge to push the car to redline through 2nd and 3rd gears on open roads, I did that quite often in fact.

My engine compression is fine around 200 and 195 across all cylinders after removing the BBSC. The person who installed my BBSC is a Import Tuner Nut who has built many fast drag strip hondas. Given the BBSC's reputation he made me no promises that my engine would survive the upgrade. He did say that he would do everything he could to lessen the chance of a blown engine. Tuning Tuning Tuning! Air/Fuel Ratio, Ambient Air Tempreture, Colder Spark Plugs, Timing, I don't know what else he was talking about but I trusted that if there were any obvious issues then he wouldn't let me drive the car. In fact one should never expect that everything will be fine when building a high performance vehicle. I took this chance. I guess you could say I survived the BBSC but I really dont have anything bad to say about the kit, my car isn't joining the Botched Boost Club =D

Hell if anyone wants an BBSC I'm selling mine =D ... I think cheap too ? Not sure what the kits should sell for now a days.

Snakey sorry to hear your story .It definitely sounds to me like your local mechanic or tuner just might not be experts on the nsx this is critical when taking these routes.I also recently purchased a used BBSC unit here from another prime member & have had it successfully work flawless pushing 9lbs & producing 410 hp on stock bottom end .I however did get a lot of input from all you guys prior to doing my set-up here was my check off list prior to install:
1)must have Aem standalone
2)water to air inter-cooler to run more boost
3)upgrade fuel pump
4)RC 550 injectors
5)Methanol Injection
6)***Tuner Tuner tuner *****/***Nsx specialist mechanic only****
7)Last of all I have to agree from the few threads i've read that you are a viper guy & would be much happier in one.If you decide to part out your kit let me know.I have had my Nsx since 1994 & drive it everyday like its stolen since that time I have only gone thru 1 clutch & 1 tranny & 1 A/C repair anyone who owns a Nsx is because they love the car.

 

[PhiAlpha44]

the second thing you should have done is NOT to share your story.

Well that's a dumb comment. Of course he should share the story. It just reinforces to everyone else to stay away from the BBSC.

drifter your really making an attempt to pick on the wrong guy...

I have had nonthing but bad luck with the nsx....My vipers were awesome and they are built really well..You could beat the crap out of them at the drag strip and they begg for more...

My nsx has been a nightmare..

-bought the 1991 for 35K in 2007 because it was GORGEOUS

-one month later I notice smoke from the engine bay and the clutch goes

-that night I drive the car and notice somthing dosent seem right after heavy aceleration

I gotta be honest... after hearing your viper stories, buying your first NSX all ready supercharged and asking about more power right off the bat... I knew this was going to end badly. The NSX is a great car. It's not a drag car. It's a track car. You've got a track record of beating the ever living piss out of your stuff..... and I was sad to hear you were buying an NSX. I'm sorry about your misfortune with the BBSC, and I'm sorry you are upside down in the car financially, but I knew this thing would end up blown up or wadded up in a guard rail. The rest of us mod and drive our cars no problem. So I don't think it's the car Snakey. And kudos to your wife, who must be the most patient, loving wife in the entire world. I think if my wife wrecked or blew up her last 3 cars, I would have had about enough of her shit by now. You really think it's "bad luck" when it's been your LAST THREE cars?

As far as the Viper being built really well? They have been on the "worst cars to own" lists as far as cost of ownership goes for years and years. Adding up the constant maintenance problems that must be dealt with annually. While in 1996 the NSX topped a reliability list along side Lexus. Sooooo..?

selling your "show" components?? That is all good performance stuff minus the stereo / monitors......... and BBSC. :wink:

You know what they say...After THREE it might be ME!!:wink:

it really helps if you read the posts, Einstein. the failure was not BBSC but lack of OIL in the engine. furthermore bbsc is never at fault but lack of tuning and/or proper engine managment. i would have hoped to see more common sense out of a longtime prime member but i guess thats too much to ask.

Swerve I guess the problem with the BBSC is that the counter parts are so "plug and play" and safe, why would you even go with this setup? I mean... there are entire threads and web pages dedicated to BBSC setups gone wrong.
Where is that CTSC thread or page? And the title of the thread is "another dead bbsc car", not "another engine blows up because there wasn't a drop of oil in it". This is post #43 of this thread. Sometimes I don't have an hour to sit and read every single post of a thread. Sorry. :frown:
I saw the title of the thread and thought "oh no".
Then I saw who it was and thought "oh.......that guy".

But regardless of all that... he should still share the story. All it can do is help others prevent the same.

 

[peiserg]

Surely you're kidding? Prevent others from driving without oil? We need someone posting that they toasted the engine because of a lack of oil to keep others from doing the same?

wow.

And perhaps if you knew more of the history between dali and basch, you might have an idea as to why someone would dedicate a website to trashing his name. That's not to say that many people blew up with the bbsc. FWIW there's approximately 150 kits still running, and I don't hear much from them blowing up these days.

 

[onestepx]

I am one of those BBSC kits still running & in perfect condition I'm not an expert on either kit but I do know with proper tuning & Ecu this kit is flawless & is proven to produce much higher hp #'s verse the comptech & for much cheaper.
I picked up my BBSC used here on site for only $2800.00 & could not be happier.410hp 9lbs of boost

Sounds interesting, let's hear it.

 

[LJSB]

Buy a used Viper w/ 86,000 miles on it.

 

[curtsr]

Snakey:
Seriously dude, please rename this thread.
Disclaimer- I'm a very satisfied BBSC user.
I think that it has been well established that the BBSC- like other mods- do not play well with a poor tune, SS box, or even no motor oil.
When this thread gets bumped, anyone trolling the forum sees the title and either consciously or unconsciously adds +1 to their BBSC body count.
Good example: the usually level-headed :smile: THEKyle read it, took the bait and piled on the BBSC bashing- in error.
Please do the right thing and rename this thread as it will continue to poison the well unjustly.

 

[snakey]

IM SORRY BUT I REFUSE TO RENAME IT....THE BBSC WAS DEFIENTLY A PART OF THIS AS WELL....THE LAST TIME IT WAS IN THE SHOP THE OIL HOSE THAT CONNECTS THE SUPERCHARGER TO THE OILING SYTEM EXPLODED...DUMPING OIL EVERY WHERE.

THE MECHANIC SWEARS HE REFILLED THE CAR WITH OIL. VERY POSSIBLE THAT THE OIL LINE BUSTED AGAIN UNDER HEAVY ACELLERATION THAT NIGHT. ILL NEVER REALLY KNOW WHAT HAPPENNED.

Im still looking for an engine. But I may be about to transfer to a differant job that pays less then the one I have now but I think I will be happier so Im waiting to see what happens before I make any transactions.

 

[doc_tai]

bottom line is your MECHANIC sucks cause he cant even install oil line right. I cant see how nsx oil pressure burst the oil line.
