its been covered many times before, people trying to obtain stupid figures from the rb20 or similar variants. speak to a mechanic and get a price on your engine ideas, see how much its going to cost (and survive relibably). instead of the 26 you may want to look into the rb30 with the twin cam conversion as an alternative

Well ATM im straping on a T3/T4 Hybrid just to try and get a little better responce so that will be on for a little while Im not going for big power figures never was not interested in high HP or I would have just brought a GTR or a RX7.

about the closest to that rpm would be a counterweight billet crank like JUN/HKS which rate upto 13 000rpm with other associated parts (note: f**kin pricey $$$)

a revving engine is a total different thing to drive to a large capacity engine. personally i like revs heaps more, and the way the tacho goes from 4000rpm str8 to 8000rpm or whatever as soon as it hits boost is the best feeling.

slow revving might pull harder but they feel sluggish and deisel like, hehe, even my old mans 5L VN group A SS with vortech supercharger feels slow becuase the power is too linear. but each to their own :P

Perhaps you could get your tach recalibrated? This would be the cheapest way to get there (just keep quiet no one will know, they will be real impressed! ). Seriously though that is a pointless thing to do, if you even got the engine to stay together you would need massive head flow numbers you would have no low down torque the cars gearing would be wrong Blah

Not a silly question about a high revving RB20.

Our goal is to cram 10,000 RPM out of these engines for drag racing purposes. The ten second barrier and beyond.

I really dont think it's that too hard a deal considering the strength of the bottom end internals.

Cylinder head max flow numbers may restrict you though. (not sure about this yet)

Their is a few threads on this, you may want to do a search.

Good luck.

      Lets say I wanted to buy this, specifically for this purpose. How do I actually perform the function. Can I still buy a Consult-1? Am I about to be burned by the fact my car is a 2000 model Series 2 R34 and thus will be some stupid other system? Do I just need this -> https://obd2australia.com.au/product/nissan-consult-14-pin-to-usb-ddl-diagnostic-interface-with-ftdi-ft232r-chip/ And with what software?

      That's probably OK. That's a face to face compression joint between two surfaces with the clamping load provided by those bolts. So.... it's unlikely that the bolts will end up feeling that load in shear, unless the clamping surfaces are not large enough, bolts not got enough tension on them, etc etc to prevent the two faces from moving wrt each other. Which... I would hope the designers have considered, seeing as it's probably one of the most important things the upright has to do apart from resist collapsing in its own right. But yes, it would definitely be worth asking them what their safety factor on that part of the design was. I tend to think that the casting, being a casting, is not necessarily the strongest bit of material in the world. It's about an inch square, and when you think about the loads that are being put into it, you have to wonder what safety factor the Nissan boys (and every other OEM engineer who has designed all the millions of other uprights that look essentially the same) used to account for defective casting, aging, severe impacts on the wheel, etc etc.

      Those bolts would be orders of magnitude stronger that cast aluminium though.  And its mainly clamping force, not shear they are dealing with?

      Except all that twisting force that is breaking a cast piece, appears to be going through 4 bolts in the picture Johnny posted of the BryPar one...

      R34 auto to manual conversion help

      By GTSBoy · Posted

      The smart approach is to use the gearbox loom from the manual car. Makes it a lot easier - just plugs into the switches on the box and plugs into the main loom up near the fusebox. Then you only need to deal with bypassing the inhibit switch. The other approach requires you to use the wiring diagram to identify those wires by colour and location, perhaps even indulging in a little multimeter action to trace them end to end to make sure, and then.... you will have the answers you need. The R34 wiring diagram is available on-line (no, I do not have a link to it myself - I would have to do a search if I wasn't able to go to the copy I have at home).
