i dont know of anyone making more than 350kw using 2530s on pulp. so i guess the answer is no

I have often wondered about that as well. I have seen a single 2530 make 240 rwkw on an RB25DET. Now I know there are some differences between an RB25 2530 and an RB26 2530, but it isn't 70 rwkw worth. HKS rate the RB26 2530 at 310 bhp, so the pair should make 620 bhp, that's 460 kw. Plus other HKS turbo seem a little underrated, I think HKS quote 10% in most cases when pushed. I have never seen a GTR loose more than 60 rwkw (and 85 awkw), so I can't work out why a pair of 2530's wouldn't make ~400 rwkw. So I can only put it down to other factors, like tuning and support stuff.

There a couple of guys I have been working with that have 2530's and they are doing all the stuff that I would suggest is necessary to get 400 rwkw. So time will tell if it is possible. :cheers:

Ben from racepace told me there was a car there with 2530's pushing 400@wheels, most people who are running 320-350 aren't pushing the turbos for all they are worth.

Emre: i thought you were running 2530's and making around 400rwkw?

400rwkw from 2530s is a big ask on pump fuel.

I had a figure of 400rwkw+ on decent fuel, but obviously it's not my daily tune.

As mentioned, there need to be a lot of support modifications in place to run that sort of power daily, reliably.

For the record, i still have the stock intercooler, factory intake, internals, etc.

Holy Jesus... Look at the size of that radiator!!!! I feel so.................. inadequate :Oops: :)

Very nice welding on that intake pipe :D

Is that oil catch can vented at all? What's with the catch can between the rocker covers, and the secondary one with the washer bottle?

the large catch tank vents to the atmosphere.

dont think the one on the rocker covers does much at all, except look pretty

i did a nice job on the welding huh..not.thats bens fabricators handy work.

Hardcore! But where do you fit the twin 18" subs bro?? :confused: ;)

Emre: Engine is all bolted together, in the car and started up with standard injectors, old HKS F-ConV and standard AFMs.... Runs beautifully with zero leaks :) Will be calling the tuner tomorrow morning at 8am and see when we can slot her in for a run-in tune with the PowerFC Pro and then I'll start pounding out the kms as quickly as possible so we can get her back on the dyno and do some proper tuning :D:);)

I'm excited! :D

      ENR34 - Leaking Transfer Case

      By AdiR34 · Posted

      You guys are amazingly knowledgeable and I appreciate it all so much. I’m currently at the local RB tuning shop, getting her inspected and diagnosed, for the t-case debacle and everything else. I’ll keep you guys posted!

      Lets play a game - What is causing my oil consumption?

      Like @Dose Pipe Sutututu mentioned, 10W30 on a built motor would not be a great idea. As for the steel wool, we think alike as I went ahead and put SS wool into my catch can as per my above posts.

      I am going to chime in here and say that is very bad advice for a built motor, making decent power of 400kW+ Especially if the rings have been gapped on the looser side. The more power you make the heavier you need your oil to be to be able to maintain that suspension between the moving parts, if not you'll have journals and bearings making love and grenade a motor. Remember that all moving parts inside the motor aren't ball bearing and are journal bearings and require oil to separate the surfaces from contacting.

      ENR34 - Leaking Transfer Case

      By joshuaho96 · Posted

      ENR34 manual transmission transfer cases are 33100-23U00 which is shared with all of the R32/R33 GT-Rs and GTS-4s. And the C34 Stagea. Do not bother with automatics, that is a huge effort to swap and the car will be worse for it. And an automatic transfer case does not have the right housing for the shifter which comes out the back of the transmission and goes through the transfer case. I already posted my response on reddit but if you didn't see it there here it is: You have almost certainly damaged the transfer case, the only question is how badly. Nobody can tell you how bad without more information. If you have a giant hole in the transfer case pissing out all the transfer case fluid then you need a new one. If it's not that bad then the only question is whether you burned up the clutches. Drain the transfer case oil and inspect for metal on the drain plug magnet. Small black filings are normal. Big chunks of metal or a ton of black fuzzies not so much. Fluid should be nice and red. Any other color isn't great. If the color is reasonably red and there's not a bunch of clutch material discoloring it or anything like that you probably got away with insubstantial excess wear not worth trying to fix. If you have to rebuild or replace the transfer case keep in mind you have to pull the transmission to get it off.
