You are correct, however if you desire you can send in a standard nissan compressor cover and Stao can use that so that the turbo still appears factory from the front. That is what I did for mine. Will take a cop that really knows his stuff to notice the difference in exhaust housings. I think the standard compressor cover starts to limit things if your pushing up to 300rwkw but on the SS-1 it would do the job well.

Just type in GTRS into the search field in the Forced Induction section and you will get heaps of info. Way more than a few people replying to your post here. To be honest I dont recommend the GTRS kit, quite expensive and looses the factory appearance so cops can get you in trouble. Get a hiflow turbo, GCG or Hypergear etc. Not to mention these will just bolt straight back on plus the fact they have factory appearance and about half the price of a HKS kit. Just saying this has all been discussed over and over before. So much info on here.

Is the ATR43SS-1 a ball bearing turbo? If it is will you be offering a plain bearing version? Throw a stock compressor cover on, can leave the 3" afm in factory location with a 3" metal intake pipe (instead of relocating afm into cooler piping and 4" intake on 0.7 compressor cover). This should be your number 1 seller, factory appearance, cheap and a responsive 250-270rwkw. Note: That dyno goes to 7200rpm so reduces the amount that the power falls over up top. This turbo has double the torque of mine at 3,000rpm and about 80% more from 3500-4000 then similar from there on, with only a 10rwkw difference at redline!

Stop being lazy man, do a search and then read through the rb25 dyno results thread. www.google.com will also answer some of your questions

Dangerous territory bloke, this is probably the most common question asked on this forum. Do a search or look through the rb25 dyno results thread. Max power on standard turbo is roughly 200rwkw, max safe boost is between 10-12psi.

Wow, these are some impressive results. This is getting very close to a standard turbo from 2-3000rpm. From there on it kills one!

Pretty sure there is another thread exactly the same from you. We answered in there. Its garbage, stock ECU is the best for an automatic. You can modify all the factory automatic settings. Nistune is an excellent solution and great value. I am running it with no issues and 280rwkw. There are guys with 400rwkw+ running it.

SOLD!!

Sold pending payment.

Hi, I have been drooling over the HKS 2835 Pro S results on a stock RB25 for ages now and finally found a second hand one for a great price. I inspected it and found it was in excellent condition! I picked it up for $1500. I already have a Hypergear Hiflow turbo which I like but was planning on upgrading to the HKS turbo. I went and got quotes from a number of performance places for install and tune. I spoke to Sam from Dr Drift and he said the turbo is in excellent condition and was an absolute steal at that price. Feel free to call Sam and verify this (mention Jeff and silver R34 and he will know the turbo). I have since decided all the reinstall and retuning costs are too much to justify the increase in response and will stay with the Hypergear Hiflow. I have since bought a 4" -> 3" silicone reducer which I will throw in. I am asking the same $1500 price, no offers please as this is a great deal as is. I will leave it up here for a week and then put it on ebay if not already sold. On the turbo ID tag is: EI 0149J GT2835-56T 700177-3 Which means it is a: 700177-3 ... GT2835 56T with 84T turbine Included: dump pipe, oil lines (with protective shielding), 2835 Pro S turbo, silicone 4" -> 3" reducer brand new Price: $1500 Located in western suburbs of Melbourne but happy to post at buyers expense.

25 neos have solid lifters too

But with what response?

Great to hear! My dump has been modified as the angle at the front pipe is different and there are lots of extra welds. My tuner is going to modify it.

That would be great Fat_Tony, that would put the issue to rest. Out of interest what results did you get from yours? Do you have a dyno sheet in the dyno thread?

Great to hear mate thanks for the first hand experience! So you run the reducer straight off the turbo then a 3" 45/90 deg bend to the afm?

Cut and pasted from another disco post: 700177-2 ... GT2835 52T with 84T turbine 700177-3 ... GT2835 56T with 84T turbine 700177-4 ... GT2835 56T with 90T turbine So is the -3 the one to get for a stock RB25? What ID's does everyone else have?

ID Tag says this: EI 0149J GT2835-56T 700177-3

Dave I will post the id number up when I get home. 89CAL, that is promising! Although I am just trying to point out that not all Pro S turbos have a 4" intake. There are two versions, 80mm and 100mm.

See thats the thing all the people on here that I have spoken to with the Pro S (joeyjoejoe, 75coupe and others) all have the 3" intake. Are you sure the Pro S kits came with a 4" to 3" reducer at the turbo? As far as I know the Pro S kits have been discontinued and only the KAI is still made.

Bugger I have just finished a custom 3" 90 degree bend with the bov return and the breather fitting. Ended up being a fair bit of work. Interesting idea with the larger AFM body. I was trying to stay on the beaten path though Nengun says the two sizes are 80mm and 100mm: http://www.nengun.com/hks/turbine-gt2835-pro-s Although I trust you disco more than nengun! Do you know the reasoning behind the larger intake? It seems funny for a turbo designed for a standard engine to require such modifications.

Great to hear with your personal experience with the 3076s, thats great info. That was my third option, 1. keep current turbo, 2. install new turbo and relocate afm, 3. install current turbo with reducer and see how it is The only cost that I would double up on would be the tuning.

I have just finished a custom 3" intake (90 deg bend) with the bov return and breather hose fittings for the current turbo and I do get the issue on my current turbo so I am thinking it might get worse.

What size intake does yours have? Yours is the KAI version right?

oh wow yours has a 3" intake as well!! Mine has surge slots too but is definitely 4". Joeyjoe's turbo has a 3" intake as well. I wonder why mine is 4"??

That was my original plan, I hadnt even heard of anyone else doing that on this turbo. Do you have experience with this configuration or just everyone else's results?
