so a week ago i was driving on our local route with a friend in his car beside me, im just driving in 4th gear with low rpms, so i wanted to launch up a little so i try downshifting to 3rd....me being a dumbass i shifted into first, my car literally jumped.....right when i felt it do that i pushed in the clutch and went to neutral, i think i went from 70-20 in like a second...haha, the car is still running fine, nothing wrong but what couldve happened?

 

Depends. What engine is in the car? What RPM range did the engine see after downshift?

 

its a d16a1 dohc in my 89 integra.....it went to about 8000 or a little higher, im pretty sure my redline is 7200 or 7600...but the car slowed down so much i got so scared

 

i done mine like that and bent valves and spun bearings had to rebuild engine.but i knew something was f*@#ed about a second or to after it happened

bent valves is the most common, but you don't know how much damage you've done until you open her up. can you hear any weird noises comin from the motor you haven't heard before?

 

coulda floated a valve

 

i know a girl that did this to her gsr hatch and she broke the drivers side motor mount off the block

nah there arent any wierd noises...well not any that i can hear because my exhaust is a straight pipe, but that day i did open my hood and rev it and i didnt hear anything

 

might have gotten lucky, but the I would start saving for a rebuild or a swap incase it does let go on you

 

when doing a rebuild for around 250hp on my d16...should i replace the whole valvetrain package or just performace valves would be good? do i really need the titanium springs and retainers? with tuning i can make it so i still gain power in higher rpms than my redline right now right? i dont plan on revving to 10k tho

 

learn how to drive. how in the hell do you shift from 4th to 1st unless you're just not paying attention

 

yeh it was a retarded move, of course i wasnt paying attention, i was looking at my friends car next to me when i did it and then all of a sudden it jumps back and slows down alot, so yeh i was not paying attention, but right when it happened i pushed in the clutch again and let it rev down

 

That has to be the hardest misshift to do ever, how hard did you throw it into first, mines pretty hard to get in if you're going over 10.

 

yea i agree with 91civicDXdude what the hell

 

i made this thread to see what could go wrong with my engine not so see what people think of my retarded move. so is there a point in leaving posts like "what the hell"....ive already admitted it was stupid and well it went into first without grinding

 

If nothing seems wrong then most likely nothing is wrong. You just got lucky lol!
