Sayajin Posted February 11, 2007 Share Posted February 11, 2007 Hey guys. I am in the process of planning out the final few things on my build and this is one of the few things that has been making me scratch my head. I know that the upgraded intake manifold has larger runners which allow for better airflow. Thats all good and well. However it is my understanding that most people upgrade the manifold in order to fix the problem with the #6 cylinder running lean. Since the runners are larger you dont have issues with the air being caught in the manifold. Now here is my question: You can easily fix the lean #6 cylinder problem with tuning. With that said, why buy a whole new intake manifold when you can relatively easily fix the problem with the existing one? Are there any other real benefits of replacing the intake manifold in high horsepower applications? If I recall correctly there is not in a relatively mild build, however I am not sure if the same applies to high, 700+WHP, applications. Thanks a lot guys. -Sayajin Link to comment https://www.sau.com.au/forums/topic/155914-benefits-of-greddynismocustom-intake-manifold/ Share on other sites More sharing options...
Sayajin Posted February 12, 2007 Author Share Posted February 12, 2007 Humm... no one has any idea or comments? -Sayajin Link to comment https://www.sau.com.au/forums/topic/155914-benefits-of-greddynismocustom-intake-manifold/#findComment-2901484 Share on other sites More sharing options...
croat Posted February 12, 2007 Share Posted February 12, 2007 1) cosmetic benefits 2) simplicity for working on the motor (i.e spark plugs etc..) 3) higher flow/performance. would only probably be needed in a large hp application. standard one is fine if you can put up with it. do a quick search, this has been covered many times.

R31Nismoid Posted February 12, 2007 Share Posted February 12, 2007 Well #1 & #2 are kinda off on that one... remember he has an RB26.

Sayajin Posted February 12, 2007 Author Share Posted February 12, 2007 do a quick search, this has been covered many times. Thanks, however I would have to disagree. The topics that were covered before all spoke of upgrading in order to fix the #6 cylinder running lean issue. I am asking, besides that are there any other benefits? I mean you can easily tune with a standalone to fix a lean cylinder, so why spend $1000+ on something that can be fixed for free? There has to be some other benefit than just that? Also I have yet to hear someone say they have outflown the stock one, which is another reason for my question. From what I have read, even 800WHP applications dont have any problems with airflow in the stock manifold. Just wanna get my info straight before I start my build. Thx. btw, someone else already mentioned 1,2 dont apply to RB26, so I wont speak on those. thx. -Sayajin Link to comment https://www.sau.com.au/forums/topic/155914-benefits-of-greddynismocustom-intake-manifold/#findComment-2901490 Share on other sites More sharing options...
BOOSTD Posted February 14, 2007 Share Posted February 14, 2007 uneven flow doesn't cause substantial problems until u reach 700hp. The nismo plenum only give a 1.5% increase in torque and the same sort of figure to even the runners.... I chose against it.

T04GTR Posted February 14, 2007 Share Posted February 14, 2007 yeah. but i have heard good things on the hypertune ones woith the 80mm throttle body. i want to get one but the wallet says noooooooooo Link to comment https://www.sau.com.au/forums/topic/155914-benefits-of-greddynismocustom-intake-manifold/#findComment-2906483 Share on other sites More sharing options...
Sayajin Posted February 14, 2007 Author Share Posted February 14, 2007 Well RIPS makes one that also comes with the 80mm throttle body. I am trying to decide if I want to get one or not with my new RB30. I know the RIPS one would have increased airflow and make tuning my simpler, but I dont know if it is worth the money. It costs about the same as the NISMO one.... -Sayajin Link to comment https://www.sau.com.au/forums/topic/155914-benefits-of-greddynismocustom-intake-manifold/#findComment-2906693 Share on other sites More sharing options...

Id personally go for something thats known to work rather than something custom you know little about.

khunjeng Posted February 14, 2007 Share Posted February 14, 2007 IMO its not so as much about power as it is response in the begger HP applciations. esp. down low.

djr81 Posted February 14, 2007 Share Posted February 14, 2007 I may be off beam a bit with this, but from what I understand a single throttle body makes it easier to run an ECU with no AFM's ie on a MAP sensor.

Sayajin Posted February 14, 2007 Author Share Posted February 14, 2007 Correct. My main purpose would be for tuning. The runners are bigger on the RIPS one IE increased airflow. I dont know if it will actually make more power, I just know it flows more air. Like I said.... I am still up in the air about it, but I am seriously leaning towards getting it just to be sure.... possibly..... maybe...... ahh im not sure! -Sayajin Link to comment https://www.sau.com.au/forums/topic/155914-benefits-of-greddynismocustom-intake-manifold/#findComment-2907228 Share on other sites More sharing options...
