yep 3040 (3082 in new terms) is way too much compressor for a gt30 hot side.

if you already have the gt35 and can easily get a smaller rear then that would obviously be the easiest and cheapest option. a lot of people seam to get good results with the .63 gt35 which is strange because its a bit of a mismatched turbo. personally i'd prefer a larger housed gt3076 but each to their own.

just keep in mind, even if you get similar results the larger reared gt30 will be easier to drive than the .63 gt35, it will come on more progressively and make traction a lot easier

I reckon it should be fine mate i have a GTX3071 with .82 internal gate made 288kw @ 21psi without boost control issues im now at 307kw @ 18psi with 25psi coming soon. YAY! Just make sure u dont use 1 of them dodgey divorced front pipes

so im thinking about getting the GT3076 with a internal wastegate .82 rear i wonder if that will be ok for 290-300rwkw without boost problems

What boost problems? It would have to be THE most common turbo on an RB25DET for an obvious reason. There are countless 3076s with internal wastegated 0.82 rears making 290-300rwkw. If you choose the GTX3076 they seem to respond well to higher boost levels above 20+psi.

But geeze looking at NYTSKY's thats a lot more top end with the 35! I know it has a lot of other mods and a fresh engine etc but if your after a car to break traction and do naughty things then its quite a good option. But if your after an all round fast car with linear power/torque then GT30 it is.

yeah i just sold my gt3582r today for 1500 and im looking at 1480 for the gt3076 with the 5 bolt internal wastegate .82 rear just not to sure what todo about a dump pipe as i wont be able to drive it to the exhaust shop

oh i though people had problems with boost control i must of misread something hahaha but yeah hopefully with 290-300 the gt3076 will still be naughty hahaha

Is it true that nowadays the Garrets are costing as much as or less than the Hypergears, which are not a fully bolt on either.?? Re: custom intake, 90deg elbow, water lines etc, the only thing that bolts on in the HG and not on the garrets is the dump. Hence makes a lot more sense to go Garret..Or did I miss something..

    • 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.
