I'll try one when I get rid of my rb20

Just got back from the gold coast where I drove a stock HCR32 kouki in Dark Blue Pearl with the dark chrome grill garnish, very pretty car.

hey, I have 34 gtt 25neo!! Chasing around 350rwkw with a good response, which turbo you would recommend?

So far I got

Fmic

3inch tbe

Nistune with flex tune 98/85

Hpx afm in a 3inch pipe

Walbro 460

1000cc injectors

Avcr boost controller

Cheers

350rwkws on E85 fuel you can use our new ATR43G3SAT model. You will need a very big exhaust and a very free flow cooler to run ATR45SAT, that can get close to 350rwkws on P98 fuel.

Hey Tao. Have you posted P98 power figures of your new 21U turbo? If not could you please?

I'd imagine the OP housing would make minimal gains over the 21U?

What size is your exhaust and what mufflers etc?

Our high flowed T517Z. 507awkws @ 22psi E85 fuel internally gated, on a built RB26dett by Forged Performance in SA. Looking at stiffer actuators and run up to 30psi. Hopefully be seeing 600awkws.

The best I've got was 287rwkws P98 fuel on 21psi. R34 GTT Neo engine. with Exhaust Tee and PWR cooler:

How is the exhaust T going after all this time? I was a bit skeptical of the spring loosening up over time and when the exhaust gets hot.

^ you're better off using an external gate with a weak spring to emulate what Tao is doing with that flapper. A few guys have done that (not here) but Google!

I wouldn't be doing the mod ;) just curious as to how it's held up over time as it's different than the ex and int types.

I know a few people who have tried this with external and internal gate mechanisms, but they have all had problems.

Well, the exhaust Tee is bleeding with not as compressed air as what it is inside the exhaust manifold. So it needs to be alot bigger. There are many ways of doing it, the most popular I've seen was that window switch motor controlled valve on ebay. That doesn't work very well as the motor gets overheated by exhaust gas.

Alternatively you can use an actuator to control the valve, which is very reliable, or just some good high tensile springs. Its a simple device, but that definitely shown an improvement.

Hey Tao, What would you recomend for a VH45DE engine? pref in single config. Street driven so reasonable response around 400rwkw minimum range?

For this engine you can run one of our ATR45 in a 1.06 rear housing externally gated. On E85 fuel that will be plenty for 400rwkws

Also vid sent in from Jason using one of our prototype ATR43 in his 1JZ, the goal was a responsive 300rwkws on Pump fuel with out VVTI. It is not an easy task as I originally predicted, project is still on going.

Vid shown 320rwkws on E85 fuel @ 22psi

Yes. Rebuild Using using a bush bearing core will cost u 700 or a Garrett bb core for 1050. Will require braided oil line and mico filter removed for either cores

Ok and what suporting mods are required i have fmi 3"dump exhust can this turbo b utilised without a tune can you set boost to afr's ratio

Wut?

Not tune, set boost to afr? What you mean man?

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
