  1. Ignoring setup or turbo choice the difference between RB30 and RB34 is significant and me wanty
  2. In summary: HKS 2530 for 230rwkw and great response Hypergear Hiflow for 250-270rwkw and factory appearance HKS2835 Pro S for ultimate response vs top end power turbo but very costly GT3076 for 300rwkw, prob just wait for GTX3076 though.
  3. There is a price at the top of $5500 for the rolling assembly so you would have to say closer to 10k all up ready to go depending on how far you go.
  4. On that oxygensensor.com what car do you enter as they dont seem to have skylines? How about an oxygen sensor for an R34 GTT?
  5. Mine didnt but I suppose mine was different because it uses the standard nissan compressor cover. On a side note, I finally got my car out to some remote twisties and had some fun. The turbo was excellent, pulled hard out of corners and gives a real straight line rush that doesnt feel to slow. On the street if you crawl around corner or roundabout it will experience some lag to get moving but if you are already going nicely around a corner the turbo is straight onto boost and pulls away nicely. Very happy thanks again Tao!
  6. I am after a RHS Plastic Undertray for my 1998 R34 GT-T Nissan Skyline It is the part that bolts to the bottom of the front bar and extends into the front right wheel arch. Thanks
  7. The idea requires the use of a non-divided manifold with a divided rear housing but the idea is to only use one side of the divided rear housing to spool the turbo up quicker up to a point where you allow both sides of the divided rear housing to flow to enable same top end.
  8. The fact that it holds 12psi doesnt mean that its not a boost leak, the turbo/s are just working much harder to keep it at 12psi. Mine ran exactly the same boost pressure just took longer to get there for the turbos to overcome the leak. If it was a huge leak then yeah maybe it wouldnt be able to hold 12psi but a smaller leak would. Can be hard to hear especially if its while the engine is running. I just blocked off the pipe running into the engine and made up a fitting with pvc pipe and used a hand pump to pump air into the system. Was super easy to hear where its leaking out cause there are no other noises. Cost me $20 for a hand pump and $6 for 2 pvc caps.
  9. How did you check that you have no boost leaks? When I had a boost leak thats exactly how it behaved, started late and just gradually built boost.
  10. Um do yourself a favour and check out his car, aint no off the shelf chips on that monster! I am in awe of that car.
  11. Agreed Baron for PM!!!
  12. I wonder why Garrett persist with both the 3071 and 3076 if there is not much difference in response?? Why not ditch the 3071
  13. After some quick searching: "You all really need to check you EGT when adjusting timing map with E85 because E85 burns much slower then gasoline you will almost certainly run very high EGT temperatures when you switch to E85. When I started mapping for E85 I quickly saw the EGT rise to over 1100 degrees Celsius, we added more pre ignition timing and the temperature went down. I now have 32 degrees pre ignition on full load and about 870 degrees EGT. Your piston rings or conrods will probably break before you hear knocking on E85 :-)" From here: http://forum.nistune.com/viewtopic.php?f=7...623&start=0 "We have come to the conclusion that running an old truck technology TO4Z exhaust housing is probably part of the problem, and are upgrading to a GT series turbo (unfortunately as the TO4Z worked amazingly well) which apparently can withstand higher heat loads." From here: http://www.efi101.com/forum/viewtopic.php?...1e463c6bdd43846
  14. Interesting point yeah thats something that I have only just got into my head. So yeah is the response of the 3071 much different to the 3076? It is a smaller wheel isnt it?
  15. Huh? Not quite sure what your asking here. Garrett turbos can be supplied with a kit that includes a dump pipe that will bolt onto the standard front pipe. Although you really should change the front pipe to a 3" to match, which will also fit. The 0.82 is the best overall exhaust housing to choose from the Garrett range as has been previously said. Although you said responsive, the 2871R (HKS GTRS equivalent) would be the best turbo for response on an RB25.
  16. I cant comment on the response difference but I know at least 1 3071 that made a nice 290rwkw. I think a lot of the poor 3071 results you see are the ones with the cropped exhaust housings to bolt up to standard dump pipe. Has anyone had a back to back comparison of the response difference between a 3071 and a 3076? I know the HKS GT2835 Pro S has more response and it has a 3071 wheel but it is running a 0.68 rear.
  17. Hopefully the response of a GTX3071 is closer to the old 3071 than the old 3076 otherwise its just an old 3076 lol
  18. Dude relax, a GT40 is a very big turbo and no way is at full boost by 3,000rpm on a 3L engine. I am also confident that it would not bolt up to the standard exhaust manifolds, there just isnt enough room. You would need a high mount aftermarket manifold to run a GT40. Find out what turbo you have (full details, exhaust housing and compressor size etc) and post it up here. Do you have the dyno sheet thats only making 392rwhp? If so, post it up. To get the best help you need to provide as much info as possible. Oh yeah and change your font size back to normal its hard to read.
  19. I am speechless, what a car!! Well Done!
  20. So u are happy for someone to guess tune your car, but actually putting it on a dyno to make sure afrs, timing and rough power are ok you are not?
  21. mad082 goes on a rant about how much he hates the R35 and then everyone gets upset when some people say they like them?? Take you own advice and accept other people have different points of view. The original topic was around a Mustang not a GT500. A GTR would smash a non-GT500 Mustang with any tyres it likes. End of thread.
  22. It is quite hard choosing a turbo that will suit your driving. It seems with skylines that its really hard to have both response and great top end power due to the high rpm range involved.
  23. Wow they are huge increases!
  24. Yeah point taken its not a direct comparison but I understand the car we are talking about hasnt been doing laps and laps to bust the turbo either? Did it make it off the dyno? Personally I think 20-22psi through a 1.06 housing will bring the temps down enough but I am not going to pay if it doesnt so I will be quiet.
  25. Quick browse through calaisturbo and number 7 and 8 on the 1/4 mile list in QLD run GT35s: #7 OVL087 - 9.95 @ 137mph ............. 27psi gt35 , glide , roo16 #8 Exchaser - 10.09 @133mph ............. RB30, GT35, mt et streets ,31psi E85, keas 3 speed From the look of that 31psi and e85 seems to me that the 1.06 will drop temps that much.
