    High-flowing a stock turbo correctly means you machine the housings to have the correct profile and have a proper match between turbine and compressor. This means there isn't excessive backpressure causing internal EGR at high RPM. This may be the "rumor" you've heard about. It won't necessarily blow up an engine with proper tuning but it will reduce how much power you can make. Proper balancing and machining is also critical. Chinese turbos like Mamba/Pulsar/etc are all generally speaking going to have larger gaps between the compressor/turbine wheel and the housing because they aren't confident in their machining and process control which means worse performance even if the general profile and everything else is supposed to be comparable.

    Greddy I have a hard time saying for sure but Tomei turbos are generally unpopular because they tended to make for laggy engines. They worked just fine otherwise but from what I can tell there were better options for the money. Hypergear is the way to go for that reason IMO. Only reason why I didn't get a Hypergear turbo was to try the HKS GTIII-SS. 

    Ok thank you for all your information. at this point i'm still not decided, but i think i will letting down Mamba turbo and wait a little more to try a high flowing stock turbo by a mechanic here at home. But i hope he as good as your Tao.

    Thanks again guys.

    Chinese turbos have a tendency to be defective out of the box. It sounds like you’re budget limited so I recommend rebuilding the stock turbo: https://hypergearturbos.com/product/rb25dethighflow/

    Thanks for the link, that is i called, we called hybrid turbo.

    They are strong? i mean i don't want one which break in 1000Km....

    There is a rumor that hybrid turbo make more EGT and killed piston head, That's what they say on the our forums at home, but I find it hard to believe, after all I'm not a mechanic...

    Simply not true. Do not even consider them.

    Oh really ? You already had problems with this kind of brands? in my country they are considered good product but too expensive...

    This is concerning. What about the ECU?

    Completely stock but car don't work, im waiting my new turbo and after that a "mapper" will configure it with nistune. (sorry if i have the wrong word)

    That depends on what you mean by "hybrid". It's a pretty meaningless thing to talk about a hybrid Mamba. Hybrid with what exactly?

    When i said hybrid i said a orignal turbo nissan modified by bigger chra etc...

    Myself personally? I would not consider an "eBay" turbo for a car that I like. Only for a shitbox.

    If you just want an easy bolt on turbo option, then you would be well advised to send your stocker to Tao at Hypergear for a highflow. It will meet your specifications for good spool, will be easy to fit, and will make plenty of power. The only downside is having to send it halfway around the world and back to get it done. There are probably turbo builders in your part of the world that can do a highflow, but we can't comment on how good they are. Tao is good.

    So for you of course, you don't recommend me mamba??

    I was hesitate between this two one :

    Hybrid : https://www.ebay.co.uk/itm/194415984663 

    not Hybrid : MAMBA GTX Turbo for Nissan RB20DET RB25DET 3" 5200 GTX3071R w/ .57 Bolt-On Hsg | eBay

    if i understand for you  neither of them....lol

    Hy everyone!

    I have to change my actual stock turbo (it is soon dead) because i have to change it, so as well do it by a bigger one.

    But before buying anything I would have liked to have several informations 😛.

    First of all, i have a R34 GTT with bigger FMIC, Tomei elbow, 750cc injectors and 400L/h fuel pomp. All the rest is Stock.

    For sure the best for me is all ot these greddy ot Tomei Turbo but...it toooo way much expensive for me. Instead of that while searching I found the Mamba Turbos, they looks nice, but do you have any feedback on them!??

    According to the opinions of the internet it's good stuff, but I would have to have your opinion ^^.

    Finally also, what do you think of Hybrids??? Hybryd Mamba?

    I also specify that I am looking for one that does not require any modification of bay or other, I am looking for pure bolt-on turbo.

     

    I already ask  the seller from Mamba and he offers me this one for exemple: https://www.ebay.co.uk/itm/194415984663 

    What do you think? Bullshit or not??

    I hesitate between this first one ajuste above and this one : MAMBA GTX Turbo for Nissan RB20DET RB25DET 3" 5200 GTX3071R w/ .57 Bolt-On Hsg | eBay

    I would add that i want a turbo which spool at the good time (not to late like 4000 rpm) but spool more or less like Oem turbo. (hope your understand my words)

     

    Thanks a lot everyone and sorry for my bad english.

    Hi guys,

    As my title says, its time  to change my R34 GTT seats.

    About R34 GTR seats, these are insanely too expensive so i give up, but i'm also in love in R33 GTR seats!

    Do you know or know someone who install it, in a R34 2 doors??

    Do you think, it will be fit? (i already know the won't be bolt on) but with a little bit modification, do you think this is possible? And about overall size, what do you think??

    Thanks a lot 

    R34/R33 Flywheel

    in Drivetrain and transmission

    Posted · Edited by zack777 

    Hello everybody,
before starting, i apologize in advance for my english because i'm french.

So, actually,  my car is stationary because I am trying to fix my gearbox. 
(for information, I have a R33 GTST gearbox on my R34 GTT, Having bought the car like this)
So I would like to know if I have a lightweight flywheel on the car or not. (as i'm fixing the 
gearbox, i would like to put one if I don't have one)

But there is a problem .... I can't tell, i can't see, if I have a lightweight flywheel or not, 
there is no description on it and I can't even verify if it's an OEM or not
(I don't even know what an OEM looks like)

Can you help me please?? 

I wouldn't want to make an unnecessary purchase (especially looking at the prices...a nismo one for exemple)
Thank you all for reading me.

EDIT: And yes i almost forgot, I can't find the tightening torque for a flywheel for R34/33 (if I have to take it apart)
And if it's different depending on if it's a lightened or not.
    
Here are the photos taken this morning.

    brake caliper R34GTT

    in RB Series - R31, R32, R33, R34 (1986-2002)

    Posted · Edited by zack777

    Hi guys,  Thanks a lot for all your responses  ?

    To talk in order, thank for the tutorial Ben C34, so if i well understant 350z brake are direct bolt on R34 Skyline chassis. But about the 370Z?? its the same?

    As you said Duncan, D2 big brake are too expensive for me, (more of 2000€ in France), and about my Driving style, i do not race on tracklap (hope is the right word) its only for street, big street if i can say. So yes the stock brake is a little weak for me, and to be honest, 355mm is also for a better looking (18" Wheel)

    But i understand what you meant, its almost as expensive as a big brake kit (and all is new, not used) 

    If you want i'm looking for the better way and the cheapest ways to have 355mm on my cars or even 340mm but not below.

     

    Today i saw K sport front kit, and its a way less expensive for a 355mm rotors with 6 or 8 piston caliper (1450€) 

    But i do not know this brand. It is a good brand?? Why on their website 6pistons is more expensive than 8pistons for the same rotors. Its the first time for me (changing break) and i even don't understand the difference between 6 and 8.

     

    Thank you all :)

    Hi everyone, i am a french gtt r34 owner and i would love to upgrade my brake.

    Instead of buy expensive D2 brake for exemple. I would love to know if Brake caliper of Z34 (370Z) is fit on our r34 Wheel hub (bolt on). (hope you will understand what i want to say)

    I want to have front 355mm x 32mm rotors. 

    In France i've tried to find some informations but i didn't found them. So i hope you can have some answers.

    If i did not mistake oem R34GTT have front 297mm x 30mm rotors. So it pretty sur that i need to change my brake caliper, that is why i thought about 370Z one. But my question is, do they fit on R34 gtt??

     

    Hope you understand and sorry for my English.

    Thanks a lot.

    R34 nismo combo-meter gauge

    in RB Series - R31, R32, R33, R34 (1986-2002)

    Posted · Edited by zack777

    Hello everyone,

    following your posts, I decided to try again the experience (because i removed the nismo gauge). After restarting everything and then installing my new nismo speedometer, I realized that the speedometer plug (the speedometer needle) was defective, probably because of that the speedometer was not workingthe first time. And there the meter works! I'm very happy, however I still note a certain lack of responsiveness regarding the tachometer needle. I do not know if this is due to the graduation which is different or indeed to a defect in my meter or else my installation :(.  What do you think? ( with the original counter the needle was more responsive).

    In any case I wanted to thank you very much, because in view of your comments I told myself that the problem was not necessarily in the difference in transmission. And its seems you're right! Hope just that this lack of responsivness is a normal thing.

    Hi everyone!

    Let's begin, i have a R34 GTT, i am a french people and if i sign in here its because i need help so i hope i can find it here, or if you can redirect me to the right place,(its very difficult to find the right forum when you are a stranger lol).

    So i will explain my problem. i just bought 4 months ago a nissan skyline 34 GTT directly from japan. The Japanese seller that sold me the car gave me in the same time the nismo COMBINATION METER GAUGE . this one (mini_20040711500984615.jpg)

    However, my skyline has an automatic transmission (converted manuel but originaly a AT). And when I tried to install it in place of the original, it didn't work.

    So i just saw on manywebsite that is for manual R34 GTT but i'm sure that is possible, i saw many video on internet (R34 GTT AT with the nismo gauge).

    Please, pretty please can you help me?? Or Do you know some  sites, forums or  people who have already installed it on an automatic skyline R34?

    I really need help, and unfortunatly nobody can help me in my country (France)....they suck.... and i dont speak japenese.... So i am desperately trying to find someone who can help me.

    Thank you for reading and waiting i hope for a reply.

    (Sorry for my bad english too)
