just bought a r32 that has been imported with a rb25 out of an r34 in it.

It doesn't have a rev limiter cause it goes al the way to 8000rpm!!

Ive put a bee r rev limiter in it, but it cant b too healthy for it cause she goes bang bang too much.

I would like the stock limiter back on cause i use it for driftin.

Does any one know where the stock limiter is located and how to connect it back up?

I always thought the standard limiter was built into the ecu. Someone probably retuned the ecu to have a higher rev limit?

A BeeR limiter will be safer on your motor than the standard one. Standard limiter cuts your fuel, your car runs lean and can damage the motor whereas the BeeR cuts the ignition, safer. With the BeeR you can choose when you want the limit to be as well which is good. Just set it to where the standard limit should be.

Correct me if I'm wrong. I'd hate to be spreading wrong information I've read off others.

Stock limiter is safer for your turbos. Bee-R will kill them very quickly. The fuel goes in and the hot turbo ignites it, causing an explosion inside your turbine. Thats what the bang bang is. Hello new turbo. Also, if its safer to cut ignition, why doesnt any manufacturer do it?

Manufacturers don't expect retards to be banging the rev limiter though...

Yes they do, thats why its there. They think we're all retarded too, and most of us are, hence why hyundai and kia are still selling cars.....

Manufacturers don't have a rev limiter there so you can bounce off it everyday. It's there so in the 'rare' even you're stupid enough to go that high it does LESS damage than what an over-rev would do.Go sit on your rev limiter for a while and see what happens then. Do you know what happens when you hit the factory limiter? The cylinder pressures go AWOL and can easily cause some serious engine damage.

Engines are built to revved, sure. But rev an engine's tits off day in, day out and you'll soon be driving a less reliable car. Things will wear out much quicker and problems will start developing. I drive my car with respect, sure I pump it every now and then but never do I intentionally hit the limiter or thrash the shit out of it and that's why I haven't had a problem with it.

Hyundai and Kia sell cars because their market is people who want a cheap car. Buying a crap Korean car doesn't make you retarded wtf...

i think your missing reading his post.

they engineer cars and usually everything complex for that matter to be idiot proof or retarded as you may call it to some degree in the event that someone may be stupid enough to do what you just said.

Yeah, fair enough :)

I have a re-tune computer in my 32 and my rev limiter is at 8000rpm :thumbsup:

I was thinking, instead of getting a Bee-R, for the $350 odd that it costs i might as well just get an after market ecu.

I also heard that they can kill the factory ceramic wheel turbo pretty quickly and that steel wheel turbos are better suited?

Realisictly your only guessing it doesnt have a rev limiter if you have only reved it to 8,000.

I have seen 32's rev limiters from factory set at 8,200. With an Rb25 in it it could still be after 8000.

I'm not suggesting to go see if it is after 8,000 just pointing out that it might be higher.

To solve your problem of wanting a lower rev limiter without a Bee-r =

aftermarket ecu and set it yourself

or

retune stock ecu by someone like Dr Drift and get him to set it where you want.

Also, something to take into account. I've noticed that the factory tachometer needle can 'float'.

After installing my S-AFC (with digital rpm readout and peak hold) i noticed that the tacho needle would read higher than the car was actually revving. Say the tacho was reading 7500rpm the S-AFC would record a peak of say 6800rpm. So you may not be revving the car out as much as you think.

for a start why are you sitting on the rev limiter? Any fool who spins wheels knows to keep the revs as low as possible... harder to do, sure, but reving the living end of the motor, recipe for longevity right there. In what instance do you need to be hitting the rev limiter? If your peak power were the last 1k-2k rpm in a race car sure... in which case your engine is built for what you expect to be a set life on that spinner anyway. On a car that spends time on the roads... swapping cogs should happen before that... 25 with stock crank and cams over 6k is just wet noise. Awsome noise the last 3rd rev range I grant you but.. not something to write home about.. 6-6.5k is a cog swap.. your 7k...(7.1krpm for s1 wanktards) is your hard limit. who waits on the rev limiter to change?

Traditionally all nissan tachos read high, but it sounds like you have a remapped ECU, send me a pic from inside the ECU and I'll let you know what's involved in lowering the limiter to a more sensible setting... may be as little as $50?

      Mistakes were made, my R34 Story

      By MBS206 · Posted

      I agree with everything else, except (and I'm rethinking this as it wasn't setup how my brain first though) if the sensor is at the end of a hose which is how it has been recommended to isolate it from vibrations, then if that line had a small hole in, I could foresee potentially (not a fluid dynamic specialist) the ability for it to see a lower pressure at the sensor. But thinking through, said sensor was in the actual block, HOWEVER it was also the sensor itself that broke, so oil pressure may not have been fully reaching the sensor still. So I'm still in my same theory.   However, I 100% would be saying COOL THE OIL DOWN if it's at 125c. That would be an epic concern of mine.   Im now thinking as you did Brad that the knock detection is likely due to the bearings giving a bit more noise as pressure dropped away. Kinkstah, drop your oil, and get a sample of it (as you're draining it) and send it off for analysis.

      I myself AM TOTALLY UNPREPARED TO BELIEVE that the load is higher on the track than on the dyno. If it is not happening on the dyno, I cannot see it happening on the track. The difference you are seeing is because it is hot on the track, and I am pretty sure your tuner is not belting the crap out of it on teh dyno when it starts to get hot. The only way that being hot on the track can lead to real ping, that I can think of, is if you are getting more oil (from mist in the inlet tract, or going up past the oil control rings) reducing the effective octane rating of the fuel and causing ping that way. Yeah, nah. Look at this graph which I will helpfully show you zoomed back in. As an engineer, I look at the difference in viscocity at (in your case, 125°C) and say "they're all the same number". Even though those lines are not completely collapsed down onto each other, the oil grades you are talking about (40, 50 and 60) are teh top three lines (150, 220 and 320) and as far as I am concerned, there is not enough difference between them at that temperature to be meaningful. The viscosity of 60 at 125°C is teh same as 40 at 100°C. You should not operate it under high load at high temperature. That is purely because the only way they can achieve their emissions numbers is with thin-arse oil in it, so they have to tell you to put thin oil in it for the street. They know that no-one can drive the car & engine hard enough on the street to reach the operating regime that demands the actual correct oil that the engine needs on the track. And so they tell you to put that oil in for the track. Find a way to get more air into it, or, more likely, out of it. Or add a water spray for when it's hot. Or something.   As to the leak --- a small leak that cannot cause near catastrophic volume loss in a few seconds cannot cause a low pressure condition in the engine. If the leak is large enough to drop oil pressure, then you will only get one or two shots at it before the sump is drained.

      Help! Leak coming under transmission

      So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
