Hypergear Turbochargers and High flow Services Development thread

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

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.

Thanks,

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

Cesar

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.

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?

    • I run 2 x 525 pumps on factory 8mm fuel lines     ... zero issues, staged of course    Your setup should work fine, all you need to do is find the restriction. A good aftermarket fuel regulator is always a good idea too. If it's not your regulator i'd be suspicious of your fuel tank breather and your tank pressurising. Next would be something with the fuel hat. Then blow out the fuel lines.   
    • Update time...... Been a crazy busy time and a bit of a change here. Sold my 370z Nismo as wasn't using it much and wanting a 86/brz so wife can have some fun at the track again also to help with funding the s15 build.  As said last time booked a cruise to NZ. The place is great, drank lots of craft beer, eat food and visited some amazing places   The plains of rohan Before we left I finally got an electrician booked and the shed now has power. Been so good being able to use it at night and not running things off a 20m extension lead. Got stuck in last weekend and reorganised it and cleaned up a lot of stuff. A few more things to tidy over time but really good to work on now. There's 13x 10a GPO, 3x 15a GPO, 4 high bay lights and 5 LED batons so will never have an issue seeing or powering tools. 437344198_7178721088892834_15829362501196293_n.mp4   Work has restarted on the s15. Removed the rear cradle so could pull the fuel tank and finish emptying the stale e85 thats now been sitting for almost 4 years 🤮 Cleaned it out and let it dry. Removed the old lift pump and have reinstalled a new lower pressure pierburg pump with all new hose and lowered the pump to get it nice and low in the sump of the tank. Also got a an old diff cover cleaned up, work has a soda blaster so made quick work of it. Going to put a 4.11 ratio diff in with a fresh rebuild thats been reshimmed for now before buying a good diff centre. And had a big change with going back to full time work. Opportunity came up to apply for a race mechanic job so applied and got it, been some big days so far but definitely enjoying it and getting to work on some cool stuff and with some great equipment. Learning a lot on proper car setup and suspension so will be valuable for the s15. I'll be part of the travelling team form next round too. This weekend will get the fuel tank and system in, need to buy a rollover valve and mount that. Get cradle in with the diff and axles then make a shopping list to buy to finish that off then start looking at cooling setup and plan intercooler pipe routing. Work will definitely be slow now on the car but will be to a higher standard.  The 180sx hasn't sold so may be heading out to Morgan Park labour day weekend for a charity event to have some fun been almost 6 months since I've driven it so will be take time to get comfortable again.  
    • I'll rent a fuel pressure tester soon and report back. 
    • It has a separate fused 10ga wire running from the battery to the relay in the trunk. 10ga on the ground also. 
    • Actually I did the fuel pump rewire 2 days after the issues started. Grinded away the paint and grounded it to the chassis behind the right panel in the trunk.
