fair call mate if ya tuner will do a deal why not aye good luck with it all aye

i beam is better for torsonal loads ie.. hitting boost. h beams can be made lighter.

it really depends on what your aiming for. then you got the whole wich brand argument lol.

from the look of it youd be safe to use some cheap china made h or i beams like eagle, scat and some of the sub 1000 a set i beams.

Sts rods may be good. But by the time you crack test them , shot peen them, resize them and get good rod bolts for them are they any cheaper then the entry level rods you can get? Even Argo are cheaper these days as their pricing seems to have responded to the cheaper rods available on the market

Thats provided the Eagle etc rods are in fact better then what Nissan put in the motor.

By the time you 'prep' the std rods you may as well spend a tinny little more and grab a set of forged rods.

All engine builders (that I have spoke to when building mine up) said not to waste the $$ on 'prepping' rods when these days after markets can be picked up for so cheap.

It really is saving minimal cash.

Go for the aftermarket rods. A set of Eagles or similar will only cost you $300 or so more than modifying the standard rods and you have something brand new that hasn't done millions of cycles already and is a better design and stronger than the factory rod to start with. They may need slight machining to set the proper pin and bearing clearances but it will be minor, most aftermarket rods are supplied with the pin and big end bore finished to bottom tolerance to allow adjustments to suit the crank/bearings and piston pin. Don't be scared off by the rods being made in China, a lot of big name companies have either set up over there or have their parts made by chinese factories, it reduces the cost to make the same product.

Just a quick point on testing standard rods.

Some one mentioned having them checked by x-ray rather than MPI (Magnetic Partical Inspection). To be honest its pointless having the x-ray done, its alot more expensive than MPI or DPI testing and unless correct technique is used it will not show up very very small cracks.

I would reconmend DPI (Dye Penatrive Inspection) Testing. This will show up any cracks or flaws and in my opinion is easier to do than MPI.

The rods are soaked in a dye for a few minutes and then cleaned off using water or a cleaner. A developer spray is then used, this will bring out any dye that remains in cracks or flaws and thus you can tell if the rods will be OK!

I was tempted to use standard rods but I think I will spend the extra cash and have new H Beam rods fitted, they are a good price now.

    • 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...
    • 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).
    • Hi, i’m converted my r34 4dr auto to manual but need help with gearbox wiring. There are bunch of wires no idea which one for speedo drive, neutral, reverse can anyone help me. IMG_6860.mov
