i was just wondering how high you can rev on a stock b16 block without it becoming to dangerous, Right now i take mine to 8700 , and just want to make sure thats a reasonable amount for the stock block.

 

8700 is really at the upper limits of the stock valvetrain.

 

no the valvetrain isnt stock, the bottom end is, thats what i am asking about how much hight can the bottom end handle

 

bump, would like to know also. planning to build a setup w/ stock bottom.

 

I currently take my stock bottom end B17 to 9000 rpm every time I drive it, the valvetrain is only springs and retainers with Skunk2, stage 2 cams. (Weekend driver). EG

Used to take my old JDM B16A to 9200 rpms with stock cams, dual valve springs and titanium retainers.. (along with 11 lbs of boost). Bottom end was total seal rings, and JE 9.5 to 1 forged pistons. (Daily driver and different car). EF

My old JDM H22a would go to 8500 rpms with a completely stock drivetrain, all day long, (daily driver, but a completely different car). EK

Hope it helps.

i would say a stock bottom end could handle 9400 or so with good valve train...but dont quote me on that

 

Ive reved mine as far as 8800 on stock valvetrain no problems yet...I wouldnt recommend it though...the only reason my car has been reved that hard is because its an ef with 350 horse on street tires...but when we tuned the car we stopped the pulls at 8500 no problem

 

i used to turn my b16 to 9 quite a bit with stock valve train...but it did end up droping a valve..lol...but that was way past 9 grand when that happend

 

9k should be okay, the guys from R&D from the import tuner contest use stock rods and rev to 9200, and last i heard, its still running strong

 

Yeah Mr.slagg....(chad) told me he used to rev a stock B16 to 9900 from time to time....and didnt drop a valve...I know that some old B16's came with dual valve springs though...so he may of ended up with a good engine....I dont have good luck with **** staying together or I would rev mine that hard...

 

9000 is way too high for being a stock block

 

You have a lot of mods, do you not rev to 9000 rpm?

i have supertech vslvesprings, but my bottom end is all stock

 

any more opinions

 

my motors built and i don't even go past 9 grand. i guess it all depends on what u have becuase if my **** was stock i probably wouldnt care but since i have alot of money into my **** i would cry my *** of like a 5 month old baby if something happened
