depends how much money you have to burn.. if you can afford to rebuild your engine in the very near future then heck... why bother with a crank collar?

So if fitting an N1 oil pump a crank collar is required yes?

The reason i ask is that i have a spare s1 rb25det that im going to rebuild while its out of the car.

I have got my hands on some reasonably priced rb26 rods, got some wiseco forgies on the way, what else should be on my checklist?

Power goal is 300rwkw

as long as your support systems are all up to the task (injectors turbo cooler manifolds etc) sounds like your on the right track. Just make SURE you invest in the crank collar because its worth its weight in gold compared to rebuilding your engine again.

i am going to take a different approach to the usual "do a search"

http://www.skylinesaustralia.com/forums/in...howtopic=110680

go there. there is all the information you need for the oil issues. IF your not going to be revving it past 6500 every gear change you probly wont need it. But anyway read that thread.

Check the forced induction guide for more info

NP's =)

oh btw high octane sell the restrictors so go to www.hioctaneracing.com.au if you need to buy one.

I have made 363rwkw outta my 25/30 and i only have the restrictor - i did not go for the drain back from the back of the head to the sump (but i dont do any drifting or track racing)

There is no made up kit. I could put one together but it would cost too much money and i wouldnt even be able to sell them because they are really easy to make.

All you need is the JUN 1.5mm restrictor which is available from hioctane (details above) OR from Japan Nengun www.nengun.com he sells them as well.

The collar is available from Nengun as well but its a bit more expensive then the version from Proengines in Canberra.

Then if you read the oil controll thread that i linked above you can see pictures and details on how the drain back to the sump was made and you can source the parts and fittings from your own local sources (speedy fitting etc etc)

all it is.. is a drain back from the back of the head to the sump thats it. very easy once you have it appart and know what has to be done. Check the pics

DID i mention to read that oil controll thread ? just double checking that i did.

im located in the usa im in need of the crank collar kit/the proper oil restrictor(whats the proper one?), and the head drain return kit! is there an online website that sells rb26 stuff like that or an rb specialist website to research and find stuff for sale like that?

are you going to get solid lifters? i kept the stock ones and they are starting to cause me some issues when try to push more then 360rwkw.

Anyway Nismo 740cc injectors are the only ones i reccomend. they will do fine for your power level and there will be room for more power later on if needed (4 hole injector's are your friend)

as a general rule your valve springs and lifters should be ok if they are in decent condition. its only when pushing them harder when you have issues.

My whole rb25 head is stock - stock cams stock lifters and stock valve springs and i dont have any issues at 360rwkw and might be able to get a little more but i dont really need anymore power.

Reason why i asked is because your getting after market cams which may put extra stress on them.

Will the hydraulic lifters f*&k out at my power aims + a bit?

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
