Hey all.

I am currently getting my RB26DETT rebuilt. i am undecided if i should get my crank nitrated. I am going to get it ballanced ergardles.

I also have a few questions...

My aim is to get 600hp out of the engine. so i know in the long run it would be worth it. however, i dont know what the specs are on the standard crank, and if i should worry about it now. so if anyone knows, can they tell me...

Where abouts in Melbourne is a place that i can get this done and also what are the prices that are getting around?

...I WANT my engine bullet proof...

thanks

JUSTIN.

dude, all jap cranks are induction hardend from new, it is about 10 times as thick as nitriding :(

well if its a steel crank anyway,thats what the heat afected areas on the journals are...

(unless you have linished of about a millimetre)

you can do it, but its a waste of cashjava script:emoticon(':lol:')

nitriding a rb crank should be about 100-200bucks. but youl have to get it straightend after... they bend from the heat

Induction hardening I can believe, but less so nitriding as it's an expensive process but I'd be interested to see proof in the case of RB cranks. The reason cranks bend (usually - not always) during nitriding is due to the residual stresses in the complex crank shape generated by microstructural changes in the surface of the crank. It's only a thin layer but the surfaces stresses are hign - and it's also the reason for improved fatigue resistance (as well as improved wear resistance).

In terms of the OP question, try Crankshaft Rebuilders in BlackBurn, but your looking at $500+. BUT don't let them crack test the crank, take it to Aviation Component Services at Moorabbin Airport for that. They have AINDT and CASA accreditation (ie they'll do the job properly).

Surely the place that is assembling/rebuilding your motor would be best to advise you on this... i mean... you are using a proper builder yes?

Hopefully they havent been telling you this

There is no need to have anything othe than the crannk stock for 600hp/447kw...

Or unde 400rwkw is basic terms.

hey not everyone uses a "proffesionial" engine builder, y do they have too? :wub: first hand experience helps u learn alot of stuff (and possibly f**k it all up too haha)

Dont have to...but the more im spending the more id be inclined to. Hell if my engine parts ass up to over 10k, the extra 1k for aprofessional to build it is candy in comparison.

He said "getting it rebuilt" not "i am rebuilding it myself"

So one assumes he is using a workshop in this instance :O

Of course, thats not to say you have to a builder at all, buy all means if you wanna DIY then go for it.

But if you are using one, you might aswell use a good one... that was kinda what i was getting at. ;)

And if his builde has said that, then i would be worried about his expiriance with RB's

thanks people...

From what i just read, i think i wont worry about getting it nitrated.

to clear things up, i am using a propper builder for this, i wouldnt have it anyother way.

Its my mates work shop. before he started working on every day engines, and cars here, he was building engines for Ferrari it Italy. so i think he has been taught from the best of the best, and he would know a thing or two about percission. i trust him alot with my engine.

Also CruiseLiner did you do the work on your engine covers and plenum your self?

thanks for the comments.

JUSTIN.

Fezza motors arent RB's, there are certain little tricks the run of the mill builder without RB expirience wonty have any idea about.

There have been a few threads about it lately too where people have small problems that would have been avoided

That said, enough outta me on this topic

      Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.

      Does the scanner do all the CUs in the car, or only the ECU?

      R34 N/a And R34 Turbo (gtt) Transmission.. Uh, Problem.

      By albyz34gt · Posted

      @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man

      Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?

      ECU sees many times the speed than speedo does (R34 swap)

      By GTSBoy · Posted

      Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
