Even if it is too small you surely should be able to get it to hold flat boost with an appropriate boost controller setup if using an external gate?

That involves using an 'appropriately' sized wastegate more than it does a method of boost control.

Those sorts of setups DO work, like running a .63 rear end on a real 3076 (3037 56t). You can do it and it will make the power but in actual fact a good wastegate on such a setup is a bandaid fix for something that needs a bigger housing. Use of stuff like E85 is also good for ping resistance ETC, which is what you need when heat from the backed up exhaust housing makes its way into the cylinder.

Consider this: You can have a massive compressor on a tiny turbine, the turbine will accept X amount of flow to reach Y shaft speed. There is a V max for the compressor too, once Y surpases the Vmax of the compressor you are running outside of the compressor map. The big wastegate is bleeding off the motors flowpath to cap off the amount of exhaust gas hitting the turbine and increasing the shaft speed.

So the small exhaust housing makes you need less X to acheive Y, then you hit Xs maximum and X becomes a constant from the compressor side impacted by revs.

Anyway need to go home, enough theorising for one day.

NB 8cm housings work on SR20's which arent naturally big gulping motors.

My 30DET is now running TDO6H 25G, budget build with Hybrid manifold and 50mm Turbosmart gate. Turbine is the 11 blade option with 12cm housing. Tighe camshafts correctly dialled. Track car, chasin

I wouldn't say that. My mates gemmi put out 200 rwhp at only 12.5 psi. The engine is newly built and will be eventually be wound up to over 30 psi.

I can make 500kw with a megasquirt as well, doesn't mean it is a good ecu.

power != features OR a good software/hardware package

the fact is a microtech has a massive lack of features and shitty tuning software, it is a huge downgrade on a stock ecu with just simple remaps, using a nistune makes it infintely better than a microtech.

you can get them to work fine with air-con, i had one on my WRX in 1999 with a Gt30 etc , before they did flash tunes, I had one on my r31 with air-con, both drove like stock actually

a good tuner can get a decent result from them

cheers

A good tuner can make anything work, eg a carby blow through setup, once again it doesn't make it a good setup. If you just stuck with the stock ecu and remapped it you'd have a much better solution, if you went nistune for $400 you'd be infinitely better off.

Why are you flogging a dead horse? i'm of to put nistune on my R31 so it idles like a concrete mixer..lol, because it has trouble even getting the smallest hydraulic cams to idle nice with big injectors on vl's or R31's.

When it comes to ECU's, some look crap on paper and in real life work, and some look great on paper and aren't that great, and despite what YOU might think, thats the way it is.....

Yes and microtech look crap on paper and work pretty average as well. Nistune etc have more features and also work much better.

You said it is a step backwards from a stock ecu. It isn't.

Hi guys.

I am writing to you from far away Russia.

I wanted to consult on the turbine .... I hope for your help .... here in Russia we can say qualified no ....

The car I Nissan Skyline R33 RB25det transmission mechanic 1995 release ...

All specs are great except for the turbine ........

In search of turbines ... saw this here

http://cgi.ebay.com/ebaymotors/Nissan-RB20-RB25DET-OBX-T67-25G-Turbo-Manifold-Combo-/160655839135?pt=Motors_Car_Truck_Parts_Accessories&hash=item2567d58f9f

What can you say about her??

Then I saw the turbine T67-25G Kinugawa ... and in search of information about her came across your forum .....

Friends please tell us all about this turbine ... Good?? Is not broken?? It is worth taking??

Ps

Read the whole subject is difficult for me because I own Angliskim bad language and a great chat through an interpreter translate the posts ... I'm sorry for my bad anglisky .... hope for your help

Has been sitting there for weeks collecting dust, my fabricator dogged me, then he turned up 2 days ago and bent up the main roll cage hoop then left, now he lost part of his finger working on the lathe at his.

Im learning to tig at the moment so i can do my own alloy work. I have no issue's with a mig and mild/stainless.

He has modded the cooler so its a return flow, so all piping will be on the turbo side. He ordered all 3inch from memory even though thats not wat i wanted.

No harm in big cooler piping. More volume after the cooler will result in a denser charge and more oxygen in every gulp id say.

Hurry up and show me what that turbo can do lol

      Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...

      Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.

      Stagea Front CV Axle Question

      By dbm7 · Posted

      Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents

      I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.
