i got a first gen b16 i was wondering can i take to 9 with no proplem

I wouldn't with stock valve train. There is no point since the cams don't make power up there anyway.

So, no.

No, you'll need uprated valve springs and really you'd want the retainers and valves to... but, cheaper, you can get away with just the springs.

A stock B16A will go to around 8600 or 8800 at a push. Power is made at around 8000rpm on stock cams anyway...

yeah, no need to rev up to 9k if your motor can't even make power up there.

Oh poison beat me to it.

Yeah, Rev it to 9000 rpms a few times on stock valve train...because ina few more days your going to be on here asking us how to fix it



Get some skunk 2 valve springs and retainers and maybe some skunk2 valves and then you can rev to 9000 rpms all day long..well maybe

Well that's even worse on stock valvetrain. Go ahead rev to 9grand alllllll you want.

you DONT need new valves, just retainers and valve springs and cams and you wont have a problem. I have a Toda valve train with the spec Bs and redline at 10k but only make power up to 8200 but shift around 8300 - 8500

i know it may sound stupid i used my freind computer jun chipped p28 i did not know rev limt was 10 k i took it there with no preoblem but i understand what u guys are saying b/c i rember on my single cam i took it to 8200 with no problem just wondering if b16 can go to 9 thanks for all the replys and the flaming

Did you read any replies above?

Yes, rev up to 9K all you want! Will you produce power at that RPM? More than likely NOT! Yes, and ECU can allow higher RPMs, hardware upgrades will produce the power and with proper tuning chance of you breaking a perfect motor which the rest of us could use become less of a risk...

Because you can rev to 9K and the car continues to roll DOESN'T mean your producing power...

Please let me know if this doesn't make sense, I would be glad to post some dyno charts to prove reving past power gains will only cost you in the end...

Well said. Many people say shift at redline. Shift where you start loosing power or slightly after. Why run your car where there is no power?

My friends SOHC blew because he always took it to redline and pasted sometime and ended up throwing a rod and busted a whole through the block. It was funny as hell! But I'd hate to see it happen someone else.

dont take it to 9k. my friend did that a few times now his car isnt running too good. oh well...skunk2 or jun valve trane it is....

Would you be willing to post the dyno charts anyways?

Well see that's the thing. We all know how "peaky" Honda motors can be. Just because they may stop making power at 8200rpm doesn't mean they will start loosing power there as well. Most will plateau for a little while. My old car made power to 8200rpm and that's all the farther I chose to take it on stock valvetrain. Could have been farther. Who knows.

If you guys really think about it actually visualize a dyno chart in your head and picture a read needle on the powerband and picture where it is at redline and where it drops to (even if you are plateauing or loosing power slightly) vs shifting early and where it drops to 9 times out of 10 a guy shifting later will have a slight advantage. I guess I could always construct a crude diagram to show this.

Now does it really make much of a difference in times vs. stress on moving components. I guess that's up for the owner to decide. My particular vehicle did.

I know what you mean and you are very correct. When I dynoed my car though I peaked at 8100 and dropped down fairly quickly after that. If i can find the dyno paper or have my shop print it out again I'll post if anyone is interested.

8487 is the highest RPM I have ever had my motor up to, by accident though, while running stock valvetrain and Skunk2 stage 1's. I don't plan on going that high again until I get upgraded valvetrain and a shift light.

hmmm i wasn't looking at my rev meter today when i tested it @ around 8,200 rpm and my motor starts to studder a little before i let go of the gas. i wonder if that was REALLY bad for my motor. i would like to know what exactly happened there....anybody can confirm me on this? thanks.

I wouldnt take a stock b16 past 8600.
I have a ITR head. i take mine to 9k very rarely. Just to show off to some of the V8 guys that rev to 6k..lol. i redlined once at the track 9238 but my tach said it was 8800.. **** on OEM tach's

My b16 sees 9,000 quite a bit.... Not on purpose.... When the turbo spools and the tires go up in smoke in first gear, 9,000 comes around quickly.

The other thing here to think about is why? If you're going up in the high RPM range on the track or when racing thats one thing, but if you're doing it just to do it, or to try to drive that way normally, DONT. Be nice to your motor. We all know these motors can go that high but the question is should you really drive it like that? It only opens the doors for more problems, just be nice to your motor unless you're willing to fix it.
