anyone know of any GTR's running the PT6262 ball bearing with a T4 Divided .84 A/R with 3 5/8" V-Band discharge? would the .84 twin scroll be abit restrictive on the 26?

I have just bolted mine up today. The exact turbo u are talking about. Hoping to have it running by next weekend after i finish a 34 with PT5558.

I have fabbed up dump pipes for both and worked out cooler piping, plumb back pipes etc

This will be interesting Jez!

What's the specs for that 34?

Stock neo motor with Type B poncams and adj exh cam gear, link ecu with flex fuel tune, hybrid manifold, mvr 44mm gate, id2000's plazmaman ffp, DVS dump and plumbback pipe. Hoping to have it running and tuned early next week. Depending if Link arrives and also waiting on plazmaman plenum to be finished.

I was wondering whether you got the new turbo in yet, guess I have the answer.

How much boost are you going to run do you think?

That i will have to see what the engine likes when im tuning it. I will see how confident i feel with the power output as its a stock motor. Also running stock cams atm. I would like to see the differences in stock cams then type B poncams. Then i will think about doing variable cam once i have to upgrade the headgasket.

Very nice, shame its a stock motor as its probably not going to be able to show its real strength. I am assuming its a ball bearing 6262, and you are going to tune for E85?

Yes both are ball bearing. My rb26 i am trying to get as much response as possible which is why i went twinscroll 6boost manifold and .8 twin scroll rear. My old steelwheeled highflows came on hard around 4500rpm ad made 307 so i am aiming to better that

Yes both will be tuned on E85. They are actually both going to be be flex fuel tuned.

We understand the stock motors will be the limiting factor but not going to build the motorS until the time comes

Nice, very interested to see where it comes in - I've always had it in my head the PT6262 would be on the laggy side, though never been sure. If it can be all in before 4500rpm then that'd be fantastic :)

Are you going to stick with 2.5" out of the IC into the plenum or go 3"?

3 inch is pretty big Roy, I usually use 3 inch out of the turbo on builds over 400kw, I know it supports at least 550wkw from a car I did recently... 2.5 inch should be fine mate for either side.

I also fabricated piping for a built STI Liberty in 2 1/4 alloy, it runs 280awkw. More important is the cooler end tank design imo.

Just curious, mine are 2.5" and the numbers suggest that for 590cfm it should be fine with 2.5", but as always its interesting that the RB26 and GTR run 3" std

I see what u mean Roy, we will find out soon but i dont think the 2.5 will limit the setup. I think the only thing that will limit the setup is the standard internals

the engine will take allot of abuse with that turbo on e85.... :P just dont be scared. These turbos come alive at around 28-35psi.

Stre180 sr20vet made 'apparently' 760rwhp on a 6262 .63 housing it would want to be a low mileage 26 to even make 600whp reliable.

I agree it would want to be a "known" engine but really 600whp is a walk in the park especially for a few dyno runs....if it was my own personal car like it is with jez i would have no problem running it regulary at 400rwkw. We see this power quite often on std 26 engines on E85. I reckon in realistic power @ 35 odd psi 700whp is achievable with that setup but i would stay sub 30 on std bottom end.... i still find it difficult to believe that 760whp result with the 0.63 housing.

Interesting that you mention that, someone I know hit 400awkw on E85 at around 22psi with his unopened <100,000km old RB26 and coolant started escaping places it wouldn't, I had thought it should be reasonably safely doable too... good to know there are plenty of others which have done so fine.

    • 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.
