Whats the Rev limiter on a R34 Rb26???

I just bought my r32 gtr a little over a week ago and it has plenty of mods and Im trying to figure out everything that could possibly be done to this car that I dont know of. Heres a link to the car with known mods

So one of the biggest questions I am having is I have no idea if the block or head is built at all and the main reason im asking this is because I honestly do not think I have a rev limiter. She pulls SUPER hard and fast from 5500+rpm and before you know it im at 8k rpm and need to shift. Well today I kinda went too far and it hit 8500 and still no rev limiter (im not trying to rev it high it just goes from 5500-8k within a second or so and im still not used to the power). This is a chipped ECU that i plan on ditching within 6 months for a Haltech, but right now im confused. Was this motor possibly built to go 9k revs or something? I highly doubt whoever ECu tuned this thing would remove the rev limiter.

I currently want to buy a Zeitronix wideband data logger system and a Bee-R just to get me by for now so i dont blow my engine but at that point I might as well save up a bit more money and just go Haltech which will do both of the above with loads more.

Your thoughts?

Im in the USA and the car was bought from japan so no way of actually knowing what was all done. I know a lot of the stuff but this one is weird. Having a huge T04R turbo wouldnt it be weird to raise the rev limiter to an unsafe spot by the tuner? the power never falls off and keeps going.

I don't know about 34's but 32 tachos like to "exaggerate"

are the r32 clusters known to be off at high rpm?

Used to rev my 33 to 9500

Don't bother getting a bee r rev limiter, they are rubbish.
Take it to a tuner and just get them to check it out. Also if you are unsure, play it safe and don't rev this shit out of it until you get it all sorted

      There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.

      Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.

      This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.

      Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
