Well after looking around for some rear brakes for mine (was mainly looking for R35 GTR rears or Alcon 4pots) which i couldnt find i decided why not put the 6pots on the rear :P

Which leaves me to these puppies i picked up the other night

8Pot Brembo Grand Terrizmo with 380mm rotors. They are actually all bolt on ready for a BMW X5, So custom dog bones and hats will be made.

You can see in the pics the pad design, its basically 4 small pads per caliper :)

hey luke real good build man, very maticulas (spelling)

i think with the manifold matt mentions in his thread in the FI section that even chinese stainless manifolds flowed 50% more the stock and after porting could only get within 15% of the cheep stainless manifolds, lower half of page 6 i believe this is mentioned

Sure am mate, Have already been ported out and hpc coated.

Reckon i should go different manifolds?

Are they Unique Autosports ported? I prefer the ported OEM manifolds over the stainless tomei and HKS style as you know. They will give better response and longevity. The 6boost are better again, will make the same power at less boost and less heat...also changed my top end considerably(extra 1100rpm of torque b4 drop off) But as you know they are a pain to fit. It wouldn't be a silly option to stick with what you have. Power wise you will have more than enough to go sub 1:15 without any issue's. It just comes down to how much boost you want to use to get there.

GTRS's need minimal exhaust restriction to punch past 500kw, that's the key. Side pipes are the only way to go. Noise level may be an issue as I did get pulled up on Sat.

Just got a mate to port them with a die grinder.

Plan to go twin Titanium side pipes (one off each turbo)

Will be good to see how the 6Boost manifolds go over time and weather they crack or not. Thats one thing why im staying stock so far.

firstly awesome build mate

i have the gtrs turbos with external wastes i also had standard manifolds with the r34 dump pipes with 22psi i made 410awkw and was only making power to 7800rpm i changed to hks manifolds and tomei dump pipes and a 3.5inch exhaust all the way through made 449awkw i think u should ditch the standard stuff my 2c worth

not that easy to make 500kw or maybe the dyno i use doesnt bullshit lol

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.

      Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.

      @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
