Hey Sedat you probably are already aware of this not sure if it's stated in the info that comes with the pump but the Nitto pumps runs dual springs and you need to remove one otherwise your oil pressu

Firstly, how the hell do you balance a block.......no such thing! Secondly, I would seriously take "Barricade's" advice and maybe refresh yourself with the rules of this forum. This is a build threa

Very nice Sedat. Very nice mate. should kick ass once all done.

What i want to know is if there is a big power difference inbetween the two plenums ?

From what I can understand is that for big power RB26 applications single throttle plenums are the way to go when you're running a single turbocharger setup, whilst six throttle plenums are more useful for retaining low mount / oem turbo chargers.

Hope that helps.

first ive heard of that...

people are making 900hp plus with the standard plenum and throttles! the thing with the 6 throttles is that it causes a slight disruption with air flow (turblulence) and can be hard to tune, however there are plenty of people that can tune them and do time and time again

Look mate, I acknowledge that standard RB26 plenum can be used in high horsepower RB26's. HOWEVER, Standard throttle bodies on big powered RB26 can cause difficulty when tuning the car (as you have mentioned) and research has found that single throttle setup ups for big power applications (500+kw) are better for flow and tuning.

Just have a look at all the big powered RB26's (500+kw) and you will see they do not use standard six TB's.

Also, I do not see many low mount set-ups running single throttle plenums, why?... because there is F all performance gained from that upgrade at that power level.

no need to get up on your high horse about it! clearly you are a little sensitive on the issue but im not going to get in an E fight with you when clearly you cant except either

There has been a massive delay with my build. The workshop who is doing my build is moving from Campbellfield to Sunshine, once they are settled in my build is going to commence. In the mean while i have picked up a Nitto oil pump.

Parts that i have so far:

HKS Cam Gears

HKS Fuel Rail

HKS T51R SPL with T62R front wheel

HKS Manfiold

HKS 60mm Wastegate

Nitto 2.8 Stroker

Nitto Oil Pump

N1 Block


Mildy ported RB26 heads with bronze valve guides ready to be sent off for a massive overhaul + CnC porting.

Because i had to wait so long for my stroker to come i took my mechanics daily for a little "test" drive. Least to say i was very impressed with the cars stock performance.

For a whizzer as big as you are planning to run, go the 90mm single throttle body plenum. It will be easier to tune. Any advantage of ITB's will be negated by such a large turbo and the delivery it will provide.

I don't buy into the 'single TB for big power, ITB's for small power' internet theory. It's been disproved in the real world time and time again. Single TB's are simpler to tune with.... and big power with an rb26 means big lag. The main advantages of ITB's are in the lower end or transient throttle- both of these areas are 'dulled' down with a large turbo.

Personally I chose to stick with ITB's, greddy plenum and twin trust td06 l2's on my rb28. I believe I achieve better throttle response, better transient response, higher intake air speed, more even air volume between cylinders and a better sound.

Cheers

Justin

+1 on the better sound!

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

      Jacks that fit under GTR lips that can reach the subframe?

      By GTSBoy · Posted

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
