I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

Are the stock BOV and breathers currently plumbed back into that bit from the factory intake pipe?

Any way, further updates with the SS-3 unit. This turbo is made for 350rwkws with optimum response. To make this work at its full capacity as possible I’ve replaced my factory exhaust manifold with an aftermarket item. The new manifold held the turbo at factory position, so stock dump and exhaust lined up fine.

With the new manifold it feels awesome at full open throttle, how ever it also feels like it have added lag down low. I will do a back to back comparison with the SS1PU after this run.

Fairly sure the AU onwards has proper double wishbone and IRS suspension so should drive a lot nicer than a EL, especially with some decent bushings/shocks/springs.

IRS was an "option" for most AU's.

But the handling is better than an EF series 2, so most likely nicer than the EL as well :)

Some interest turbo development Stao :)

I will

Be saving up for this ss-3 unit...!! Looks tempting to me!!..Whats the supporting mods for this set up A-Z list please if u could..im really keen..

You haven't even seen the results yet?

I bought that off a guy on ebay for $400. I think its a coated ebay manifold. I've fitted the SS1PU back on it seems to have lost abit of response on partial throttle, how ever does seems to delivery wider torque range on wide open throttle. I might do one comparison run using the SS1PU first, to see the behavior of the power and torque delivery due to this aftermarket exhaust manifold.

yeah that would be very interesting..

it looks the same design as the HPI, the ebay ones are alot different in pipe design..Unless there is a HPI copy I dont know of..

ED..ok found em in UK..cheap too..

Tuning the ss1.5 on saturday morning. Just fitting the 740cc highflows fron ebay use at the moment. Flow fairly even but spray is like a hose.

would be interested to know how the injectors go.. aswell as the turbo ofcourse

Those manifolds seems to work fine. If it can get me a certain percentage of extra power and torque then I won't need to design a huge turbo reaching target goal.

Also every thing fitted and lined up fine.

I will make this SS3 externally gated through turbine housing.

Tao would you be able to mod any housing of your turbos to be externally gated from the bottom the housing with a 38mm vband flange to it? I'll be interested to see how this housing performs. I wanted to get a old housing on one of my planned turbos a while back modded to have the wastegate on the housing but I kept thinking there may be some turbulence and flow interference in it so ditched it. I really would love to run a screamer pipe lol and have a my dump customised to suit either a plumb back external gate setup or an atmo external gate setup.

Tao how well do you rate those TFI pod filters? I really need to know if my apexi power intake is a restriction...

Yes can be done, how ever big external gates are more effective when working with big turbo in small turbine housings. The SS2 and SS1PU versions has welly matched wheel size and housings. It might not make much difference in that setup.

I got the TFI filter for $10 inside discounted tray at Autobarn. lol. Its a 4inch filter with 2 set of sleeves. Worked fine, didn't had any restrictions at all.

      What brakes on R34 GTT(Europe)

      Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.

      Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
