This is a newb question... Does a 1989 CRX Si have a stock rev limiter? D16A6? I don't want to find out the hard way...

 

yes i think its 6800 0r 7200 rpm

Yes, I don't know of any Honda that doesn't (88-up anyway). Though this question seems pretty retarded to me, you say to find out the "Hard" way like your hoping to rev that high safely on a stock motor and make power?? If your motor was built enough to make power that high it would not be a worry since it would be" built" and tuned for it so that leaves me thinking your motor is stock and you plan on revving it to and/or past the rev limiter for what reason? Honda put the limiter in for a reason and anybody making power past that should know what the valve train can take

If you gotta ask on this one your likely gonna break something anyway.


...or maybe I'm wrong

 

k i'm not retarded i was just wondering. I've built engines for mustangs and vintage pontiacs dude. This is the first "honda" i've owned and yes i know that the dirty d's drop off around 5800 rpms. I have another thread posted here about some building questions if you would like to give input here: https://honda-tech.com/zerothread?id=2280823
I am used to big displacement and carbs so the tuner world is new to me. that is why i'm asking questions...

your red line is is at 6500 rpm. your fuel cut off is at 7200 rpms.

 

Thank You! That is actually what I wanted to know! Thanks man

 

7500

 

Well it actually has a cold rev limiter at 6800 and once it reaches operating tempurature it will jump to 7200... but I would hope that nobody on here would rev out a cold engine anyways

and lets not forget the "Type R" sticker clause that allows you to rev to 10,000 when properly applied.

...good info on the cold start, never knew that one

 

Yes, they have a stock rev limiter on accelration, but NOT ON DE-ACCEL. So if you down shift like I have from 5th to first (or 4th, I dont remember) on the freeway, there is no limiter. So keep that in mind.


(Luckily I pulled it out of gear right when I hit 7k, And I didn't have my liscense yet and I was only like 15 or 16, That's why I made that newb mistake!)


Oh, and as long as you have a stock ECU, there will always be a rev limiter!

ok

1. a rev limiter can be removed from a stock computer.

2.it dont matter if u down sift the ecu will still have a rev limiter in it,thats why honda put it there to pervet over reving.

3.your ecu must of had a removed rev limtier in it. ie egay mugen and spoon chips.

thats about the closet thing ive seen to the right answer yet.you know why it has a cold rev limit of 6800? keeps u from over revving it on a cold motor and blowing the head gasket out!!

 

The ecu revlimiter is electronic. If you down shift from say 5th to 2nd your rpms will be over the stock fuel cutoff. And yah you can remove the fuel cut off from a stock ecu but then it wouldn't technically be a stock ecu would it

if u are driving in 5 gear and down it to second it should hit the rev limiter and your right if it was removed it was chipped and not a completely stock computer.

 

idk ive never really done this before but my understanding is that the "rev limiter" is just fuel cut-off... and if thats true... it wouldnt stop the engine from over reving if you droped in to 2nd at too high of a speed... a rev limiter would only stop the engine from over reving under its own power

I dont recall him saying he wanted to rev that high. In fact, if he wanted to rev that high, why would he bother asking? He would just go out and floor it if he didnt care. Possibly and more then likely while the car is still cold. Without any oil. With any other lubricants replaced with sand.

correct.

When miss-shifting from 2nd to 3rd to 2nd (oops) the tranny can pull the motor up to 14,000 RPMs well over any limiter, there is no tranny limiter.

 

Yeah and when you have Japanese decals applied your car is automatically JDM... yes, even a mustang...

 

Thank you for pointing that out...

thanks for pointing that out... yeah I use the new synthetic sand lube on all engine surfaces now...

Actually, the car is using a quart every 1,000 miles. I want to do a mini-me and take the stock exhaust off, and new clutch, sleeves, pistons, rods, etc.

Skunk2 exhaust looks pretty cheap any good?

Hey I'm a Honda Driver... only the best products goes in my ride...

 

Skunk2 exaust is actually surprisingly good my car had it when i bought it. It doesnt sound like a fart like 4 cylinder engines can very easily sound like sometimes
