RB335

Anyone tried a EFR8474 yet on a RB26 or 28?

There's a few people running 800 plus HP with stock size ITB's without too much issues. I wouldn't be worrying too much about it. I had the same questions when I did my build.

So I never knew that the 9180 has an Alluminium CHRA option. I ordered mine from Hi-Octane website and the option wasn't on there, so I assume I got the cheaper steel CHRA. Do any rotating parts, e.g the backing plates where the wheels go get changed to alluminium or is it simply the bearing housing? Run in on my 2.8 with 9180 is done, now time to max it out and see how it drives. My future plan is twin 7163's on Hypex manifolds, all seems to be pretty promising but the new 9274 looks very promising that might be an upgrade in terms of response from the 9180

Does anyone have any idea how a 8474 would compare to a 9180? The 8474's compressor flows the same 95lb/min as the 9180, but the catch is, will it ever flow reach the potential that you see on paper in reality with a smaller turbine than the 9180?

Hi Guys. I'm wondering if anybody knows which 100mm cooler on a R33 GTR can keep the mesh. 9/10 people say they had to cut the tabs so remove it but I have heard isolated situations of it clearing such as a HKS one that somebody reported. I also know that HKS and Blitz i think released some new coolers too. If anybody can report something they use off the shelf that works let me know please, prefer with swept tanks to suit OEM pipes. Hypertune was test fitting their new 100mm intercoolers and came back to me it doesn't clear. So I'm looking into the Jap brands. Cheers.

Hi Guys. My engine is finished and awaiting to be tuned. The idea is building a responsive car with a smooth idle and street manners. I have gone an EFR9180 1.05, I like the idea of the new 9280 but for 100hp more it doesn't seem like a big step up unless it has some hidden merits that I don't know of. Seeing factory cammed cars have made good power on single turbos, I wasn't looking to go too big with cams, so I settled on something that will still let the car idle nice. Some basic info on the power making stuff : Nitto 2.8, custom spec pistons for 9.6:1 C:R Ratio HKS Vcam Step 2 - 264 inlet 9mm lift. Tomei 260 9mm lift Exhaust 1mm Oversize valves, ported head and worked chambers Hypertune ITB inlet manifold 6boost Twin Scroll manifold. Twin TIAL MV-S Gates. EFR9180 1.05 Haltech Elite 2500

Does anyone have a 9180 for sale?

Hi Guys. I'm after a EFR9180 or 8374 Cheers

Hi Guys. So in pursuit of making my RB26 a well even and smooth running engine I've done a lot to it, putting all the best bits on it I'd like to know some more information on the Nismo and Greddy manifolds. The question is do they make the engine run smoother and respond better. The theory is these try to get the airflow to each cylinder as even as possible, especially fixing the 6th lean condition. Speaking to many tuners about it and a lot are in disagreement, most say with modern ECU's you can adjust the individual injector to ensure a proper A/F mixture so these manifolds won't help. My theory still is though if one cylinder is getting less airflow, for that power stroke it makes it is making less power and pushing down with less power down the crank, and the engine won't ran as smooth. So my first question is, while the theory exists, in practice how much of a difference does it make - I don't mind spending the money if it makes some improvement in your guys experience if you've ever done back to back. I know a lot of SR guys notice improvements when they put aftermarket OEM replacement plenums on but have not heard so much talk with RB26's Much reading I done mentions that this helps get the twin turbos working more evently, I'm running a single though. The 2nd question is, Greddy or Nismo, big price difference. And which ones can or can't be replaced with the engine in, apparently the engine needs to come out for these to be fitted. The Greddy one i wonder why is a 2 Piece. I'm also considering, the Hypertune multi TB plenum

So Guys. What is the consensus with the 7670? There appears to be only 1 person who has run it here on a worked RB, that being Kinkstaah on your 2.8 with VCT. I'm going to be running a very similar setup : RB28 Nitto 2.8 with 9.5:1 Compression HKS Vcam 264 in. Tomei 260 out I'm going to have my 7670 on there and probably end up bolting a 1.05 rear housing to it. But from seeing the results people are saying the 7670 on these bigger engines while will work, will give no added response over a 8374 and make less power - while not proven but that's what I'm getting from the hearsay. So does anybody have any real results from the 7670 ?

Hi Guys. Does anybody have a Vcam Step1 phaser and/or cam for sale? Also chasing a 1.05 rear housing for a 7670 if anybody has one spare. Cheers.

Hi Guys. I'm going a custom stroker kit on my RB26 it's going to be about 9.5:1 comp ratio. My tuner has tuned heaps of them on Pump and no tuning issues. He hasn't ever done any 10:1 2.8 stroker kits yet and we don't know of too many people or any at all that have gone that high. I'm posting here to ask if anybody here personally has done so and how was tune-ability like on Pump and did you run into any issues. I will be running a Flex fuel setup anyway. Thanks.

Cars still not ready maybe in 2 weeks.

Interesting thanks for the ideas guys. Yes I would put like a big 3" round or 4" round inlet on my custom made airbox just always wondered what the upper limits of the R33 GTR Air filter element were or XR6T one i guess it might be the go guys. iruvyouskyrine How was the intake noise like with your ARC Box? Yes contemplating whether to custom made something or just modify a RB25DET ARC Box.

Airbox for big single turbo (R33) Hi Guys. I am going a big single turbo on my R33 GTR but I want to keep induction noise down. Does anybody know of any aftermarket airboxes for the R33 (bar the ARC one) that can be made to work with a big single, perhaps even if somebody has made something from carbon. The closest thing I can find that can probably be adapted to work is a R33 GTS-T ARC One, but I don't know how well they flow and never seen anybody running a big single turbo with it. I was thinking of getting my fabricator to make one from scratch that has a big 3 or 4" hole near the headlight area but don't know fo any Panel filter that will flow for about 500rwhp setup I was thinking getting one fabricated to suit FG XR6T panel filter but apparently their stock intakes are only good for around 400hp Was also considering getting something fabricated to use R33 GTR size panel filter, but again unsure how it can flow around 500hp Failing to find a panel filter capable of the job I was also thinking a big pod hidden inside a custom made airbox I appreciate any suggestions perhaps if something low production exists out there. I'm not to keen on the CAI sheet metal enclosures. Cheers.

You'll probably have to stretch that budget a long way for a good midnight purple one.

When putting the plenum back on you may find it difficult to clear the two air delivery hard pipes that go between the gap between runners 5 and 6 of the plenum, hold the manifold in this angle to clear them then gently manoeuvre it back to the correct location. Another hard part can be putting the intercooler rubber pipe back onto the manifold, you want to loosen both sides and use all your strength to first get the BOTTOM RIGHT section on, even if it's a little bit of it, do whatever you can to maintain pressure on the hose as the bottom right part of it needs to remain over the plenum lip, holding this in place, use a phillips screw driver and gently walk the rubber over the lip from the bottom working your way either clockwise or counter clockwise whichever you find works the best.

An update on this to add some tips and tricks to help 1st timers out more. I cannot edit the thread. On Step 11, when chosing whether to keep the hardpipes attached to the manifold, or to keep them attached to the rest of the hosing assembly on engine before manifold comes out. I would probably chose Option B, as otherwise if you go Option A, getting that gasket and bolts to hold that hardpipe to the ISCV is very hard. I also reccomend putting some sort of protective paper, electrical tape around the brake pipes as you are very likely to scratch these up while working around this area, when the manifold comes out. Removing some of the rear lower nuts can be quite difficult without losing them, as there is about 1 or 2 where you cannot get your hand in all the way to remove the nut and the washers. Here you can get some magnets and tape them onto something and extract them that way. Also using very large long nose pliers, you can remove the washers using the gaps in the inlet manifold runners from the top

Hi Guys. Just wondering if anybody has ran a Turbotech boost tee on a Rb26dett. I'm thinking because of the way the boost control on the rb26dett is plumbed, You would have to block the boost feed to the existing solenoid off then install the aftermarket boost tee on the hose that comes directly off the manifold? Has anybody done this and how did it work out? Cheers.

T-REVZ i had read your useless comment a few pages back and that's crap. I like people to enjoy their cars get out and do something car related you got a problem come see me in person wonder if you've got the guts to say it to me.

HI everybody was good to meet up last week we appear to have a good local Skyline and GTR group going on here. Thank you Elle for organizing. SAUWA forum is here for us, and for us only, and we use it like true car enthusiasts of which is rare in these times. I encourage anybody to make more events because effort of 1 sometimes never can make it to the full potentia My GTR still is in works, I know a few guys with GTR's who are near completion who will join the group. In future times we will do a full cruise, we will do a Skyline one, and then a GTR exclusive one. So please get more people to join our local forum.
