I think this is incorrect. Mine is 8600

Umm... for some reason I doubt this. The gauge cluster shows a "red" of ~8200 IIRC, so the rev limit shouldn't be that far off, 8600rpm max. Don't know for sure though...

Re: rev limit on b16b (90dxhatch)
The stock limiter is 8500 rpm on a b16a, I have a dohc Del-sol.
But if you do a cpu upgrade or iginition you can go to 9000 rpm or more but just to clairify this post 9000rpm is safe for a stock head.
It may not make power up there and won't do yah any good but like I said its safe if you want to go past 8500.
My built motor/head with Type R cams loves top end but I don't go past 9100 rpm it starts to lose power past that. But fun stuff from 6600 rpm-9100

Wow.
First of all, the B16A rev limit is at 8200rpm as verified by piggy-backs, standalones, and ECU dissections. That's 8200rpm, not 8500 on a B16A.
Also, the stock B16A head is FAR from enough for 9000rpm. The ITR valvetrain has a problem with valve float at 8800rpm let alone B16A, and their valvesprings are considerably stiffer than OEM B16A.

The B16B is A JDM MOTOR... IT has NO rev-limiter, only a speed limiter at about 120mph on a stock JDM ecu! The same goes for B16A's running stock JDM ecu's....However I wouldn't rev past 8500-8600 rpm on a stock valvetrain or your valves will end up trying to mate with your pistons.......
AND For anyone who thinks 9K is cool on stock internals...My little brother revved the **** out of his for about 4 months until one day the valvetrain got tired of 9K and dropped a couple valves in cylinder #2 and turned his head into SCRAP metal and damaged the block severely (Broke the cylinder wall, twisted the rod, and shattered the piston which part of was found in the exhaust)..........SO rev as high as you want, just BE WARNED that sooner or later the valves are gonna float a little too much and a few hundred rpm will end up costing a few thousand dollars..........

VERY ******* SERIOUS.....BY the way before you start talking ****, why don't you reread this thread and discuss the engine everyone else is...
B16 B.............But either and or or.......JDM **** doesn't have the same restrictions as ours....And I'd love to see some ecu dissections...Showing a fuel cutoff post a pic, just remember for a J-spec ecu not domestic......

1. Big Ern was talking about B16A and 8500rpm. That's wrong, reasoning cited above.
2. B16B from Japan DOES have a rev limiter, like most other JDM Honda engines. The JDM B16A is limited to a max engine speed of 8200rpm, the JDM H22 is at 7600rpm because Mr. P13 says so. Ask the CTR owner who posted in this thread if his ECU has a rev limiter... or maybe it was installed by boat operator on it's way over here :/
3. The only thing you're right on is the speed limiter, which JDM Honda ECU's tend to have, at least a lot earllier than US... even the Skyline is speed limited. For example, the P13 ECU had this information extracted from the ROM
The Speed Limit is at $2EAC
the stock value is B4 or 180 in dec for 180kmph or 115mph
change it to FF or 255 dec for 255kmph or 158mph.
The Rev limit for JDM P13 is at $2EC1
The scalar is 48.15dec just multiply with dec value of that loaction.
aka 76xx rpm
And that's from a JDM P13, manual trans and virgin.
4. Here is a CTR/ITR spec sheet: http://www.geocities.com/Motor....html
(look at the dyno graph, look at the max engine speed for B16B)
My point is, JDM ECU's DO have rev limiters. You can even ask all the CRX guys getting the JDM CRX or Integra XSi engines.... I Know for a FACT that auto B16A ECU's are limited to 7600rpm.
Now that I think about it, I can't think of a SINGLE engine/ECU combo in a production car that does not have a rev limiter.

you are a ******* moron. of course JDM ECU's that are unchipped have rev limiters.

b16a ecu....jdm p30 has a rev limiter of 8200.....at least the 4 that i have are at 8200
b16B ecu's do have a rev limiter.....i do not know where it is......i have installed 2 b16b's....and driven 3 more.....they make power to about 8400 as proven on the dyno.....

????? are you kidding?Of course it has a rev limiter,as does nearly every other mass produced engine.Ive had 20-30 JDM engines and every single one had a rev limiter.Ive never had a CTR engine but have had an ITR and it had a 8600 rev limit.
