Amaru Posted October 29, 2003 Share Posted October 29, 2003 Argo rods with ARP 2000 bolts are good for upto 11,000rpm and 1000hp (or so I was told), this is what I was looking to replace my stock rods with.

N I B Posted October 29, 2003 Share Posted October 29, 2003 Crower rods are good and cost the same as Argo and ARP VG30 bolts are an easy fit to RB25-26 rods.

Steve Posted October 29, 2003 Share Posted October 29, 2003 I think Spoolup has some HKS RB26 rods for sale at the moment, about $1750 or thereabouts. Wouldnt have a clue what they are rated at.

RNS11Z Posted October 29, 2003 Author Share Posted October 29, 2003 Would they fit a Rb25. Im pretty sure Rb26 & 25 rods & bolts are different Link to comment https://www.sau.com.au/forums/topic/28130-aftermarket-rods-options/#findComment-586200 Share on other sites More sharing options...
Steve Posted October 29, 2003 Share Posted October 29, 2003 I was under the impression that the rods will go in no probs, sorry if it is a bumb steer, cos I am not sure? Either that or team them up with an RB26 crank and bobs your uncle:) Link to comment https://www.sau.com.au/forums/topic/28130-aftermarket-rods-options/#findComment-586203 Share on other sites More sharing options...
B-Man Posted October 29, 2003 Share Posted October 29, 2003 team them up with an RB26 crank and bobs your uncle That's it - I think. BTW - That price for HKS Rods is pretty good ! And as I re-call a brand new RB26 crankshaft is like $900 from Nissan - That would make a pretty cheap 2.6L bottom end. If I wasn't down the track on my re-build I would have snaffled them up.

damslo Posted October 30, 2003 Share Posted October 30, 2003 rns11z unless you are currently making more than 300rwkw you dont need to change teh conrods as iam using the factory ones and using it for racing purposes and still havent had a rod failure and going on what i have seen i am nit going to change it either. It is only a ploy buy the manufacturers to tell you that they cant handle it so that you spend unneccesary money on stuff that you dont need so that you can tell the boys at the pub.

N I B Posted October 31, 2003 Share Posted October 31, 2003 RB 25 and 26 rods are the same so you can fit any 26 rod in a 25. Link to comment https://www.sau.com.au/forums/topic/28130-aftermarket-rods-options/#findComment-588916 Share on other sites More sharing options...
B-Man Posted October 31, 2003 Share Posted October 31, 2003 This is just my experience, and I state up front that I am no expert: When I rang Eagle I asked them this exact question - Eagle do make rods for RB26 - So when I called them and told them I wanted to buy Eagle rods for my RB25 - They told me that they don't make them yet. But they would soon ! I really don't get this.... Sydneykid says that RB25 rods can be ordered but you must quote the dimenstions and specs of the rods and not ask for RB25DET rods. This is meant to be because there are OEM agreements etc in place and as part of this agreement the vendors can't market parts as RB25 spec. So if this is so, where can I buy RB25 forged rods ? Carillo, Argo, Tomei, (all very expensive - much more expensive than Eagle Rods for Rb26) See the problem ?? I also asked the Eagle guys if they made a conrod for another vehicle which is the exact size and dimension as the RB25 ones - And they said no. So does that mean that the extra 100 ccs for the 26 comes only from the crank differences ?? From all the engine builders I've been talking to - none of them have suggested that the 26 rods can be used in a 25 - Seems weird - not that I am doubting you Steve-SST. I wouldn't have a clue - So I go by what others tell me and am just relating my experiences to date. Maybe I wasted my money shot peening and cryo-tempering my std rb25 rods when I could have ordered Eagle rb26 rods ?? But I wasn't going to pay $3000-$4000 for Carillo or Argo rods - although they are very well engineered.

Simonster Posted November 26, 2003 Share Posted November 26, 2003 Originally posted by B-Man What engine ?? Eagle don't make rods for RB25DET ARP don't make bolts for RB25DET I used the standard RB25 rods in my rebuild, but be aware there are at least 2 types. The weaker of the 2 ive seen has a small lump on one side of the rod shaft about 2cm below where it connect to the piston. This type is very weak, the other looks exactly the same as the RB26 rod. These are the ones i used which I shot peened and linished. My engine is built to support 550hp all day- just food for thought for As far as the rod bolts, yes ARP don't make them for the RB25, I used ARP for the SR20, works just fine Good luck with your re-build Link to comment https://www.sau.com.au/forums/topic/28130-aftermarket-rods-options/#findComment-589701 Share on other sites More sharing options...
N I B Posted November 26, 2003 Share Posted November 26, 2003 Eagle have no rods for any RB but we have sent an RB rod over and they will be on the market soon. All RB 25-26 rods are the same but some RB 25s have weaker rods but a lot have GTR rods,the motor with weak rods has a few other things that make them the dog of the family. Rb26s have a longer stroke but the rod is the same size as the 25 the piston on the 26 is shorter, Fact. I garranty this is true as we do a lot of Skylines. Crower have rods for RB25-26s out now.

B-Man Posted November 27, 2003 Share Posted November 27, 2003 Steve, so what you are saying is that I can use Rb26 pistons on my RB25 rods and I get an extra 100cc ?? Are the cranks the same ?? I thought not. Wish I had known that before I put the ARIAS RB25 pistons in ! Damn.....

KamikazeR33 Posted November 27, 2003 Share Posted November 27, 2003 so u can put rb26 gear inside a rb25 no probs? no machining required? Link to comment https://www.sau.com.au/forums/topic/28130-aftermarket-rods-options/#findComment-591632 Share on other sites More sharing options...
N I B Posted November 27, 2003 Share Posted November 27, 2003 Yes but if you use the 26 cyl head you need to have the block drilled and tapped to 12mm bolts as 25s are 10mm.
