Actually, what kind of power figure would I get on a 0.63 housing? Would an external gate be a better option maybe, since loads of people swear by them?

With RB25det you should get about 260~270rwkws on about 18psi with external gate. The .63 turbines is very good for street response but not very good for big power and torque.

Shipping to WA is $35.

Stao, any result from the 2530 spec turbo yet?

Im aiming for 250rwkw but want response like a HKS GTRS. I have a both the stock 2IU turbo and a stock VL RB30 turbo to work with... maybe mix and match?

Yes I currently have them avaliable in .82, and .84 Twin scroll. The .82 comes with the 6 bolt dump pattern or a 3inch Vband.

This is dynosheet is with ATR43G4 (600hp) profile in .82 turbine and .70 comp

Car's got:

850cc high flowed injectors from Created

Ebay cooler kit

Tomei 260 Duration by 8.5mm lift Cams

3inch exhaust with metal cat.

Tail 38mm external gate vented to atmosphere (drilled on top of stock manifold)

Z32 AFM

Z32 ECU with nistune chip and modified loom

Any indication on info like this please? am very interested in your service stao, still need help to make up my mind.

That turbo's currently on a RB20det R32 and Here's his reply. hopefully I'll get a dynosheet soon.

This is a print of his reply in my pm.

Stoa, Have you used a turbine housing like the one you made for me before? I just had my Front pipe and Cat replaced with 3" items and the turbo is now hitting over 15psi with no boost controller. I have loosened the preload on the actuator arm and noticed with how the Vband connecter is on the turbo the wastegate flat have very little room to move. I can take pics if you want to have a look.

Is this turbo housing 6 bolt oem dump pattern or 3 inch vband?

That dyno is fantastic, its up around 300rwkw for a long time not just at peak rpm!

I have heard the 6 bolt oem style is restrictive, do you find the 3 inch vband is better?

Cran:

The actuator's only got about 8mms of movement so the clearance is enough.

Before the ATR43 were released all TR43 and TR43is were running this type of turbine housings which I haven't had any issues, but most of them were running higher then 15psi.

I advise you to get the car dyno tuned to have the correct afr and timing set.

Hary:

That turbo is running off a 6 bolt dump. The car had abit of miss on high rpms which you see, I think if its not popping it should have a slightly rising curve to about 310~15ish KWs.

Have you got any comparisons between 6 bolt oem style and 3 inch vband ?

Sorry but this just seams strange to me whats the point of a 10psi actuator if the turbo can't manage to do anything under 15psi?

Stock turbo wastegate flap has a hell of a lot of movement compared to this one.

The space specified is enough to the amount of movement by the actuator. Also this is a 1KG actuator so to me its doing what its suppose to do.

any way, with the 6bolt pattern, the overall area is greater then the size of the exducer of the turbine wheel. There would be a slight restriction, but I don't think its would affect any thing more then 5KWs.

if it is a 1kg actuator the minimum boost will be 14psi not 10psi

Hi Tao

Just reading this and he says his Oil line is too short.. I won't have this problem with my r33 rb25det yeh and everything should fit and line up perfectly??

Thanks

They are sold with a T28 drain flange. It is shorter then the stock T3 flange, so you need to extend it with few inches of power steering horse.

Stao, what company makes your plain bearing CHRA? I know you can make a turbo with a garrett ballbearing CHRA but what are the plain bearing types? where are they made and by who?

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again? 
    • I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer 
    • Yes that’s another issue, I always have a front mount, plus will be turbo plus intake will big hasstle. I’ve been told if it looks stock they’re fine with it by a couple others who have done it ahahaha.    I know @Kinkstaah said the stock gtt airbox is limiting but I might just have to do that to avoid a defect so it atleast looks legit. Or an enclosed pod so it’s hidden away and feed air from the snorkel and below Intercooler holes like kinstaah mentioned. Hmm what to do
