B16A2 Chip??

[tayl51601]

Does anyone know which chip would be best to unlock the rev limiter on a B16A2 motor on my EK4? I want V-tec to be able to stretch a little further to about 10,000RPM. Also i have seen that some chips allows V-tec to kick in at 4,400.

If you know which chip would be best and possibly where to get it from it would be a great help!

lol, you've been watching too many movies buddy. If your motor is stock, revving it to 10,000RPM will blow the mofo up :wave:

[aaronng]

Agreed. You aren't going to be able to rev it to even 9000rpm for long durations if the internals are kept stock.

[tayl51601]

I have seen it done before, i had a mate that bought an accord that could go up to about 12. I heard it was just a safety thing that honda installed so you dont blow your motor, my motor already goes up to 8,500 so it wouldnt be too much more than what honda has already made it.

I've seen a b16a2 blow up at just under 9000 rpm. It all depends what condition the engine is in. But upping the rev limiter on a stock ek4 would be a very bad thing. Poor little stock valve springs wouldn't know what to do.

Did your mate tell you 12000rpm? Or did you see and hear it go up to 12000rpm? I've had people tell me that their engines can go 11000rpm, they wish! They were just exceeding the numbers on the tachometer and guessing that it was 11000rpm. :)

When you are at 8500rpm, an additional 500rpm could determine a reasonable engine life or a conrod congee.

lololol

[rpm boy]

and dont bother about the vtec kicking in earlier cause the hi lobe cam isnt designed to rev that low so if anything it would loose power and wreck ur torque curb....

mate i'd like to see this 12k revving, i'm suprised that it didn't blow up on the spot. My other car wore out its piston rings just revving up to 9k, and that's one that has a stock 8,600k cut off.

Are you sure that its not a faulty rev meter???

Even spoon engines & 20v formula Atlantic engine rev only till 11,000. And these race engines need rebuilding after a few races, some even after each race. And these were purpose built.

V8 supercars only hit 9k.

I dunno who has been telling you the this crap but, your asking for major engine damage. Don't listen to every story you've heard.

Also your not gonna make power that high up, you will have passed your engine's efficiency

Most of the Chrome/hondata or other piggyback ecu chipping will do it for you if that's what you want to do. But i don't think any tuner will generally do this for you as when they have to map it the engine might blow up on them, and then they would be liable.

If everyone was able to make more power by just removing the rev limiter we would all be doing it.

Start researching and think properly for yourself .

Thanks for letting me know, i wasnt sure because the chips i have seen were about $20 which already shows that its a load of crap i guess. I have had a couple people reckon they have done it before but never seen it myself no. The guy who reckons it went up to 12000 seemed like he didnt really know anything about it either so i doubt it actually was going that high.

Just a quick question though, do you know which headers are best for my car? I was thinking JDM 4-1 but it would be good to know if there are better ones i could possibly get

[trism]

lawl those chips on ebay?

they do nothing at all

DON'T DO IT!!!!! i've got the Spoon one which I used only to get my vtec crossover down to 5200rpm. it serves no purpose and it sucks... you can see a massive dip in my dynograph as a result.

Only reason to get one of those chips is if your on a budget and want to fine tune with something like an AFC Neo and needed the lower vtec crossover because your camshaft specs required it.

A 4-1 header has more high end,sacrificing low/mid range.A 4-2-1 has good all round drivability,so more low/mid range.Most go for a 4-2-1 design unless you want big top end power.

Those chips you speak of are no better than the ones I'm eating right now. They enrichen your fuel load, you lose power...and you'll be out of pocket 15 bux. May as well spend your money on a cheap ass pod filter. It just may do more...speaking of which...15 bux special at Supercheap at the moment.

I beg to differ, by b16 made more torque low end with the JDM 4-1s than my stock headers, so go figure.

I loved my 4-1s stock look and great performance all round.

Depends on the pipe diameter and length tuning. I can show you 4-2-1 design that not optimised and probably runs worse at low to mid RPM than a proper 4-1.

But that's vs stock Limbo any after market will have more than stock.

Yeah I believe that Aaron but the vast majority or consensus is what I said right?

JDM 4-1 are "stock" headers. Stock in Japan. Similarly, my aftermarket headers probably make less power than stock JDM EuroR headers...

[Limbo]

Beeza - i had 2 aftermarket headers before the JDm 4-1, the JDM 4-1 was better than them also
I beleive some 4-1 do loose abit of low end power. I've noted that the longer the headers merging point is from the exhaust ports, the better the lower end power.
It doesn't matter if its 4-1 or 4-2-1

[trism]

i like the merge point to be way down back under the engine

seriously, this should be in the noob forum..

Those chips are rubbish..

Dun change vtec coz its not designed to be any lower.. Factory set it at optimum.. Any change must be done for a reason by ur tuner..

and ur mate who says he can rev to 12000rpm should really take lessons in "Honda cars" and the whole engine RPM thingy..

[beeza]

I'm totally confused because I always knew it as a 4-1 header is for more top end and 4-2-1 for better low/mid...

That used to be the case I guess. The stock AUDM Euro headers are 4-1, but have good low-mid range but piss all top end because it uses a weird mushroom shaped collector where the pipes meet. So that is another case where 4-1 gives poor top end...

Some1 needs to give a summary.. No one mentioned about the noob forum part though..

hey guys, hearing all this talk about blowing engines reving it around 8k is scaring me now. My b16 has got about 180k on the clock, is there any mods i can do to it to help avoid my engine blowing if i flog it once in a while?

Yup, change the rods, pistons, rings, pins and rehone the sleeves. Change the valve springs, new valves and clean up the carbon deposits.

It's Honda,it won't blow :)

That is true to some extent... Have a look at this: http://youtube.com/watch?v=y1jXsBCS0xM

[dsp26]

mine gets 9200rpm at least once a week.. higher rev limit should be seen as nothing more than a safety measure if you don't have the supporting mods. i would rather rev past the 8200rpm limit than whiplash the engine when it cuts at that rpm....

removing the chip though to opt for the stock jdm p30 rom...

these stupid chips/roms disable the o2 sensor and lets your car run in closed loop even on cruise... pretty stupid and shit on petrol

in a good week where i don't go past 4krpm i'm still lucky to get 330km before fuel light goes on.
