hey,

just wondering what conrods people reccommened for an RB26?

do i have to get a certain size to match the pin or are they usually the same size?

im using arias pistons with the supplied pins.

i understand the standard ones are good for around 500HP?

im looking to have around this figure so to give piece of mind i think i will upgrade now while its apart.

so what rods and where should i get some..

nengun have a set for around $1500 but there may be a cheaper alternative.

thanks again

for 500HP there is no reason you cant retain the standard rods but have them nitroed, crack tested and prepped. Standard rods will handle the power without a problem though you should use ARP or Tomei rod bolts when you rebuild the engine.

I have hear nothing but good news about Argo rods...

If i was to build another rb30det it'd be with them....

Saying that, you would get the same sort of repsonses when asking for what pistons to use....it comes down to personal preference.

I like to ask the engine builder what he uses, then ask why :(

Have been running 450ish hp at the wheels on standard rods shot peened for almost 24 months now without a problem. I am using ARP rod bolts though which is where the weak spot is in the rods apparantly.

Keep clear of R.E.V rods. Friend of mine ordered a set thinking they were a bargain. They arrived pre-assembled, when removing the rod bolt it stripped itself and snapped. Really want something this brittle in your engine when you cant even remove the rod bolt to put it in the engine?

Unless you want to push massive amounts of power or raise the rev limit, standard rods should do you fine (using a decent quality bearing as well... I previously used NDC bearings (Nismo are supplied by NDC) ad they are a tri-layer metal style bearing. After 10,000km the top layer had started peeling and was on its way to spinning. The car has no knock what so ever, and have always used Motul 300V Chrono oil changed every 2500 - 3000kms. My preference for bearings would be King.

EDIT: Forgot to mention, as others mentioned get them shot peened to remove any surface weaknesses, and if you have the cash cryo treated to add some extra strength.

A few of us in WA are using Pauter rods:

Pauter Billet Rods

The quality of these things is top shelf and they have handled some serious HP (as well as surviving some catastrophic unrelated engine failures).

If your bank account is really flush - have a look at the titanium rods :(

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...

      Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?

      Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.

      R34 Gtt Wheel Offset Advice

      By Kinkstaah · Posted

      This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
