BIG PROBLEM!!! MIGHT HAVE A BLOW TURBO

[rb20jdmizzle]

I think that i just blow up my turbo. I have an s14 with rb20det-auto. Just finished the swapping job 2 weeks ago...but still hadn't all the way finishing on the a/t control input wiring. Anyway, i took out for a spin yesterday to let it warm up since i hadn't run it for almost 2 weeks due to time and a busy-job. I don't exactly how much boost i was running since i hadn't instal the boost-gauge. Anyway, the car pull pretty good and hard to redline and it kinda surprised me...and so i put a little gas to it and next thing i know....i heard this funny noise on the turbo side....sounded like the fan or the turbine broke off and it started to died out on me. I came to a stop and started up the car...but it died out on me everytime i put it into drive. I tried it several times and next thing i know....it won't start!!! Damn, . Luckily i wasn't too far from my house. Anyway, does a blow turbo do that (prevent the car to start up) or maybe something else like...BAD MAF or TPS SENSOR? I got so piss off and mad at myself yesterday that i posted the car for sale!!!! but came to think of it...BLOW TURBO...isn't that bad. that will give me an excuse to get a new turbo!!!!

Kind of hard to say if its a stock turbo the gate should be set at like 10psi if its stock, check all your ic pipeing if one blew under boost, i dont see why the turbine wheel would blow off.

[Vkoslak]

I blew up my turbo, car still ran fine. Just no boost.

With it dieing like that, I would say I have to agree with rb20detodd, check your intercooler piping.

I had all kinds of problems with intercooler piping until I got some good stuff fabricated.

the 20 runs 10psi stock?

and ill third it, sounds like intercooler piping.

[Vkoslak]

My 20 was running 10psi before the exhaust wheel came off.

[rb20jdmizzle]

Yeah, i might have to agree with rb20dertodd too since my ic pipping are not perfectly connected. I will have to check on that. But what so funny is i squared that i heard the funny noise (like the exhaust fan is breaking off) on the turbo side. What's so pissing me off now is the car won't fired up!!!!

Oh well, guess i will have to taking the turbo out and see...and maybe check my timming belt also. But then again, it could be the spark plugs since i am using the ngk pfr5g-11. Will have to check on that also.

Man, doing the auto swap is a pain in the *** when trying to figure out how to make the car shift right and i still hadn't figure out how to make it jump into O/D. I know that all or most of you have the 5-speed and i had never drive a rb with 5-speed but i had to admit that automatic on an RB swap is so sweet....redline every gear and it so smooth and what so funny is that i still had not change my fuel pump! That kinda wierd . I am still piss and mad at mysefl and still want to sell the car, but i got to admitt that everytime i pop the hook and look at the engine...YOU JUST GOTTA LOVE IT!!!!!!

[Shocker]

whoa?.. you didnt change your fuel pump? i hope i read that right, it was sort of hard to understand. If you didnt change your fuel pump thats a definite MUST! dont want to go around leaning out your motor now... as for the car not starting now sounds like a boost leak to me, if your turbine flew off you still are able to start your car, you just wont be getting any boost. check it out.

Reason i didn't change the fuel pump is because i just didn't had time to do it yet. I am changing it to the 300zx tt fuel pump. Well, just hopefully it's a boost leak and that's a reason why the car won't start. But as far as the turbine flew off....I still square that i heard broken noise on the turbo side...oh well, guess i will find that out when i taking the turbo out. But that's a great news that even if the turbine flew off ...the car is still fired up (i didn't know that! ), now i can concertrate on the boost leak....IC piping...timing and possible the tps or maf.

[Kansei240sx]

Yeah, its most likely intercooeler piping not a broken turbine wheel. Check all your IC piping and clamps, and try getting all T bolt clamps instead of worm drive clamps becuase those things are ok for low boost applications, but still suck.

And btw, im not trying to be police on this but, can you try and make your posts more legible. I can barely understand what you're trying to say haha.

Anways, good luck getting it running again man.

[rb20jdmizzle]

That's funny, but you are right about my writing. Ain't never good of anything Just kidding man. Yeah, i will taking everything apart this week and go over it carefully, and this time I'll make sure that i hook up the boost gauge and boost controller before taking it out again for a test drive. BTW, thanks.

[srdrps13]

lol im pretty sure your turbo did not "fall" off haha. im gonna be the 100th person to say it but check all your intercooler pipings and little things like making sure your cas and maf harness is plugged in. your car wouldn't die from a blown turbo.. you'd just be running the JDM rb20de lol

[rb20jdmizzle]

Ok man, I guess you guys are right even though the turbo is blowning- up....the car is still gonna fired-up. But ****, i didn't know that (somebody hit me on the head PLEASE!!!!) But for real man, i had never messing around with turbo. Always been a N/A HONDA.......Yeah, yeah, i know....i know. You ain't got to say it lol.

[OKRB20DET]

why u rockin the stock bov and a blitz? is that the new trend?

[s13_drftone]

check turbo piping, turbo turbine and vaccum hoses and look inside your piping

check the damn pipeing

thats what my rb20 stock turbine was putting out on my that their autometer booust gauge. put-ding

[Gold Digger]

I noticed that too. Can someone shed some light on that setup?

[Vkoslak]

One thing you might try would be to unhook your MAFS temporarily. If the car starts with the MAFS not hooked up, then you may have a problem with your wiring or sensor. I managed to melt my MAFS wires. twice.

[rb20jdmizzle]

Oh yeah, i know that you guys gonna noticed that. No lol, reason i put the blitz there is because i hadn't make my other piping for the intake and i was in a hurry to see how the car run.

Oh yeah, i had noticed that too about the MAFS. Before my car would started up fine even without the MAF hooked up, But it won't rev past 4000rpm. It would studder out on me if i tried to rev past 4000rpm, and if i plugged the MAFS back on then it would died out on me, and so i re-wired the MAF and plugged it back in and next thing i know....it rev up like a champ (all the way to redline with no heristation at all).

But like i had say, my car will started up even without the mafs hook up. So, i guess that i do had a problem there eh? thanks Vkoslak, i just learned another lesson.

[Vkoslak]

Can you unplug the MAFS and start it right now? It is normal for the engine to run without the MAFS. If you can get it to run right now without the MAFS, but it dies as soon as you plug the MAFS in, then your MAFS or the wiring to it is the problem.

[rb20jdmizzle]

I hadn't starting up the car nor take a look at all the problems yet since i always came home late from work. But i know that before i re-wired the maf wiring, the car started up fine without the maf, but would died out when i plugged the maf back in. But when i re-wired the maf wiring, it started up fine without the maf, and would still running when i plugged in the maf. So, i don't think is the mafs or wiring.
