Threw a rod in my VQ
so i was having choppy starts for a lil while and was getting money together to see a mechanic then i accidentally red lined my baby racing a grand prix....
( my fault not payin attention) it ran and started the same for a like a day and a half. then i stopped to get gas dropped 30 in the tank went to start it and clank clank clank so i called a tow truck got it dropped of to a mechanic they ran some tests and called me sayin i threw a rod 
i guess i need to swap the motor but can u guys freakin believe that. i died a lil inside that day
my VQ only has 94,000

I dont see how you can redline an auto anyways. you dont have extended rev limiter do you? i think the mechanic is b.s'ing. I have left my car in 1st gear by mistake at the track while launching on 75shot, or even 50shot + few pounds of boost and bounced of limiter, and nothing.

well i thought the rev limiter would kick in too cause it did a previous time but i specifically saw it go to about 6,800-6,900 rpms and smelled a smell i never smelled on a car before but i'm not mechanically inclined well they never said that that was the reason i'm just sayin there was that plus previous starting problems and they're tellin me to swap the motor

I've bounced mine off the rev limited at least a few times, no problems to report.
Did you buy your car used? Could be the original owner didn't change the oil regularly and that led to your problems.
What do you mean by "choppy starts"?

redlining will not throw a rod unless you have other issues that are causing it to happen. unless you were doing something that hurt a rod before that day, its unlikely that is what happened, although still possible. the redline is there to keep you safe, normally you can bounce off that all day without any issue. shoot, i bounce off my 7100rpm limit way more often than i would like and there sure isnt any issue coming up, certainly no thrown rods here

Did you have a puddle of oil under the car? Did the rod puncture the pan? thrown rods and spun bearings are like night and day! With a thrown rod you wouldn't been starting anything! But with a spun bearing you'll be removing the engine to get that crank rod journals undersized .010, .020, or .030" ... good luck.

Sounds like you did this to yourself knowing about the "choppy" starts and manually shifting an automatic to "race" a slug grand prix.....The choppy starts were probably a rod or main bearing telling you it's about to go, I also doubt you threw a rod but likely a bearing or bearings are gone. Good luck getting it repaired though!

Doesn't sound like you threw a rod at all. Trust me when it happens it's scarry. Basically you'll hear a snap, metal knocking around and if you are unlucky the rod will shoot out of the pan or the side of the block. If your at speed when this happens you'll be blinded by the oil smoke.
I had a 460 come apart on me on the freeway before. That's how I knew.
As for actual damage I'm almost inclined to say have your timing chain checked. Your tentioner could have given up the ghost.

the rod, sometimes referred to as con-rod, short for connecting rod, is what links the piston to the crank. it's not good if the rod breaks (or if anything breaks, for that matter).

I once did a 3-2 shift instead of a 3-4. As I let clutch out I knew I had done something wrong, I don't think I let the clutch out all the way. If I did, it wasn't more than 1 second. I saw 8K+ on the tach.
That was 4 years and 160K km ago. No problems at all.

so no one here has raced there max..... i doubt that. who wouldn't want to they're great cars and that don't mean i abuse my car i baby it. and it was a ssei grand prix supercharged not a slug but i didn't know he was super charged till he passed me, i was all ready doing 55 and saw him flying up on me thought i could take him but i was wrong i am just going to ignore sooner he all ways pulls that same bs. i read on hear allot not 5 Freakin years though I've only had my car for 2 1/2 and been on here ever since so if I'm a newbie so what u should welcome and help ppls on here for the love of maximas. No i didn't bust through the oil pan or nothing else for that matter, i am going to get a second opinion from another mechanic and i will continue to race if i feel like it. i got allot of wins under my belt because everyone underestimates these 5.5s for some reason well thanks for all the input though it's very helpful and any more is greatly appriciated.

at you posting about street racing. Perhaps you didn't read the rules when you first became a member?

Everyone seems to be beating on him for manually shifting his auto, nearly, indirectly blaming the manually shifting to be the culprit. Seems on topic with me, and when does a thread ever stayed on topic around here?
To the OP, there will continue to be useless flaming, etc on you racing on the street & manually shifting an auto, so in the meantime, get a compression test and UOA.

Also what were your oil change intervals and type of oil you used.

Holed the block too.
I knew the harmonic balancer was bad after I kept blowing the splines out of torque converters. Finally figured out the balancer was bad and replaced it a week or so before the engine blew. I'd been down on Forest Lane in Dallas (where everyone used to cruise in the DFW area) and then down on Manana (street races) where I had annihilated a 1970 LS5 454 Chevelle (365 hp stock, I believe) with my 1971 Chevelle with a .030 over 350 (look at the cam lobes, that was one big Crane cam!) and was on my way home on LBJ freeway. Just messing around, running it up to redline 3rd gear and -boom- then silence. Walked to work that whole summer saving up the money for another short block.
