Hey guys i am getting my RB26 rebuilt

currently it has eagle rods in it with ARP 2000 rod bolts i was thinking of changing them to Manley rods as i like the machine work on them but what is everyone else using etc i keep heaing researching and some people dont like the eagles and others say they dont last long but heaps or people seem to have no issues.

i just dont want to have to pull rods out after say 100,000 kms because they are shitting them selfs, so what are you guys running / happy with them and prices etc?

Thanks

What power is the engine going to make, what revs etc.

Carillo rods....

Argo rods.

then eagle, spool, OEM rods with ARP fasteners.

I think it's been discussed numerous times. I'd do a search but the search function is broken.

I got Manley rods, new in box because they were cheaper at the time than Eagles. If you have Eagles new why not spend the money on something else? The engine life may depend more on machining, assembly balance, then eagle vs Manley, and the oil system, do you have a billet gear oil pump yet?

Yep the motor is getting a tomei oil pump its an R33 long drive crank

Looking at CP pistons

metal head gasket

head restrictor to 0.9

ported head

HKS 256 cams

springs and ti retainers

Proflow in sydney has the motor taken appart now and getting it ready for building and assembly etc has a Blitz KKK 660R turbo kit so just going to run what is safe for the tune i dont have specific power goal in mind just want it strong and reliable

just keep the normal RPM range 8k not real interested in reving the snot out of it

I think you'll be fine with the eagles. I wouldn't change them just for the sake of it. sure there are better rods. I'm not sure any aftermarket rod has a life of 100,000kms on a modified engine. more important will be how the engine is built, how it's tuned and then how it's maintained. that stuff will determine how long it lives. not the rod brand.

I know of a set of CP pistons to suit RB26 for sale right now, 86.5's, brand new in box with stickers etc - they're in Sydney, ready to go. Part number SC7310

They were delivered only today, not going 2.6 anymore...

$900 delivered to any Sydney postcode. PM me.

i currently have everything ready to go pumps on its way to the builders, but just read a few storys on the eagles they were in the motor and used for about 20,000kms but the previous builder did a shotty job and pistons and bore are shot hence the rebuild

I dont mind upgrading the rods and i was thinking of getting some kelford cams and sell the HKS ones but seeing the car is mainly street didnt know if it was worth it

I was looking at the Nitto rods or the Carrillo ones just dont know which way to go?

i was just looking at the nitto, spool, and looking up the argo ones now, the more i read the more i seem to get lost this car will be a daily drive most of the time not getting flogged and get serviced like a 2 dollar hooker

i have read about the Nitto but why would you say they are good in your opinion?

i know it sounds strange i guess its manily because i have researched so much and am a bit turned off by the eagles after so many people bagging them, and i heard they wont last 100,000kms but dont know for sure? seeing that it needs a rebuild i though i may as well change them now while its all apart?

I have heard good stuff on the nittos no bad stuff yet, and these build quality seems better than the eagles and i dont want to drive the car and have to strip it down after componets wear out :(

Well put it this way.

Stock rods would handle the power from that turbo (from what i can tell googling it). So aftermarket rods will hold fine mate.

As long as the tune is good, you use good rod bolts and aren't going to sky high RPM - realistically they aren't going to fail on you.

You've got more chance of a bearing spitting itself in 100,000km than you do of a rod going sideways.

Its hardly ever the parts that fail/wear out most times. Its how its all screwed together and the tuning.

You could put the best pistons and conrods in there and if its not built right or tuned right for that matter too, it will still suffer a premature failure/wear out.

Dont get so worried about the parts youve chosen. Just make sure your builder hones the big ends and small ends to suit desired bearing crush for big ends and pin to bore clearance for the small ends. Make sure they are balanced end to end as well.

So long as he does his job properly you wont have any issues.

Ignore most of the smack talk people say in forums about rods and pistons and the rest of that shit. Half the people have no idea anyway, its usually something they have heard from a mate, or what their mechanic has told them(who isnt their engine builder, though you will find the tuner will blame the engine builder and the builder will blame the tuner, unless they are one in the same). One person will have a bad experience, that expereince will have the cause incorrectly blamed on a certain part because of rumours, despite other people having success with that same part. Suddenly forums are filled with trash talk with no real evidence provided and then you will base your decision on this after reading said forum. And you will throw away hard earned money because you believed it.

Its just like tradies and their tools!

Keep and use the rods mate. Nothing wrong with them.

Thanks guys, keeping the rods they have ARP2000 rod bolts in them got custom order CP pistons to get the disired comp ratio the tuner wanted and its all put togeather now by Proflow in sydney, Just engine managment is taking care of it all for me and they have been given me 110% confidence in them so once the oil pump goes on its back to Jem to get reassembled :)

Thanks agian will try and put up a build thread if i can :)

    • Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.
    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.
