cruiseliner has had that username banned but he has the jun rb27 with To4Z, not the GTSS combo you mention :)

JustinFox is someone who had a thread recently about his GTSS dramas and then the solution.

justinfox is running 2530s mate. or at least he was.

Good results Nick as im telling you now on MSN... lol.

Here is part of the convo just for others, no point re-typing it.

GT-RS - 19/20psi

gt-rs 125km/h ~150rwkw

gt-ss 125km/h ~255wkw

gt-rs 150km/h ~255rwkw

gt-ss 150km/h ~300rwkw

Thats ~ 5200rpm

/end convo!

Anything after the approx 5200rpm mark and the GT-RS have caught the GT-SS and continue onto the bigger powers as you'd expect.

So you can see for a street GTR why the GT-SS dominate.

But for a drag or more hp aims, the GT-RS do well... Ill have a look for a good 2530 graph too, should be somewhere in the middle of the two

Whoops, sorry. They are GT-SS turbos "JA JUNG"+ funny jap clapping.

So 370rwkw from GT-SS turbo as 1.3 bar? Was that on PULP or race fuel? NOS?

Strikes me as being a little... well... optimistic unfortunately.

GT-SS are tiny-tot turbos of the HKS range.

Not much bigger than factory, around the same as R34 N1s.

When everyone makes 300-330rwkw from them, sitting around 20-22psi.

Then one car, just one... comes out and makes another 40-50rwkw from nothing doesnt add up at all.

If you said 2530's... it would be smack on the marker. But 370rwkw on PULP, thats very much unrealistic for GT-SS.

how do you think slides highflows would compare to the gt-ss in terms of response?

Without seeing them on a car with results, impossible to say

wow, thats a good post with good info from a person who can comment on both sides

i didnt think the GT-SSs could stay with the -5s so close, unless you mean the 20kw difference was the before and after cams with the -5s?

surprising is an understatement

go you little GT-SSs haha

Both set ups with the same Tomei cams 260/260 9,15mm nly the turboes changed

very interesting alchemist. basically the -5s have the same response as the SS and more power. can you refresh my poor memory with the specs/housings/part no. or the -5s?

just read back to your post alchemist. basically you are running the garret "2530" how different if at all is it from the HKS 2530? The only reason I ask is the HKS version is easier for me to get, and it comes of course with all the gaskets etc which save me some hassle.

Always a bit of a worry when you have stumped up for the cash & you start seeing topics like this.

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
