This thread used to be interesting but now it's dull. Can someone chuck some turbo(s) in a car already and report back (preferably with skid vids)

Or run some laggy twins and blow the 2nd turbo

Call hypergear... pay him x amount of dorrah... say you want x amount of hp. Recieve turbos... install.. post result

Nah don't do that. Plenty of good turbos on the market

Of course like GT-RS turbos. Comes on at 5700rpm and quickly shift before you 

1. Smash the limiter because you have a "great" powerband OR

2.shift too slowly and fall off boost.

Amazing :)

What is the difference in the number of blades in the turbine wheel? 9,10,11?

To answer your question, it will slightly change the efficiency of it. Depends on the design. What it won't do is make it a multiple times better, eg 11 blades isn't 10% more flow than 10. Remember the more blades you have the more volume inside the compressor is blade. Doesn't help.

Flow is still a function of area and a number of other factors so number of blades is only going to have an smalll change in the characteristics of the compressor. Realistically an optimum design is going to take account of the operation parameters, the housing size and shape as well as the blade design. because garrett or whoever uses x blades in y new design, doesn't mean that x blades will be better in an older, different, compressor.

what wheels should I try?)))

these will definitely work
Inducer Dia. : 46.52 mm
Exducer Dia. : 60.13 mm
Extend Tapered Tip Exducer Dia. : No Extend Tip
Overall Height : 24.50 mm
Trailing Angle : 45 Degree
Blade : 6+6

Inducer Dia. : 47.10 mm
Exducer Dia. : 60.13 mm
Extend Tapered Tip Exducer Dia. : 64.98 mm
Overall Height : 29.50 mm
Trailing Angle : 45 Degree
Blade : 6+6

Inducer Dia.: 49.62 mm
Exducer Dia. : 61.98 mm
Extend Tapered Tip Exducerdia : 65.90 mm
Overall Height : 27.63 mm
Trailing Angle : 60 Degree
Blade : 6+6

You need to use only one wheel with an inducer of 62.6mm and an exducer of 83mm mated to a turbine with a 74mm inducer. Preferably in a twinscroll housing.
I can't be more specific as I don't have all the details on these wheels but they seems to perform very well on RB26.

  • Like 2

I dont know why you are asking? You haven't listened to anything anyone has said all along ?

If they are gunna work use them and post your next failed result! 

I will say this AGAIN.... NONE OF THIS SHIT WILL WORK! So just get over it and buy a single!

I like the way you think! ?

No one knows what will work as you are in uncharted territory, you’ll have to just be the test subject

You're a twins guy maybe you should offer him some advice? Pretty sure you've thrown some Frankenfail ideas around here before? What would you recommend he tries next?

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
