Why are you replacing the turbo at 100,000km (if that's genuine km)? If you want a bigger turbo you have to also look at intercooler, exhaust, injectors, fuel pump etc and of course an aftermarket ECU or a Nistune chip. The only coils I would suggest are OEM or Splitfires - and of course plugs while you are there.

The crank sensor is unlikely to need replacement nor is the sensor on the air intake (MAF sensor) but by all means replace the O2 sensor on the exhaust downpipe.

There is heaps of information in the Stagea (wagoneers) section especially in the DIY section.

Well if you are after a stock replacement it depends where you are - good idea to put your city and country at least in your profile. Most popular replacement that you can run with stock ecu etc is one from Hypergear (look up his thread and give him a phone).

Check the turbo for shaft play first. If that is OK, just fix the leak. If you want to go replacing the turbo, you'll be finding you need to do quite a few other things as well to make it worth it: exhaust, valve body upgrade if an auto car, FMIC, and tuning.

If you need to swap turbos without the supporting modifications, Id ask about turbos smaller than the 21U hypergear high flow unit. That will keep the engine response and power curve close to stock - something that is an important consideration for a daily driven, heavy vehicle.

Well I know hks do a 2.8l strocker its got the plate from khs under the hood saying it's a 2.8 with the engine builders name with 2.8l badges all over it probably got taken out before it come over and yeh I'm 99% certain its stock turbo seams like stock ecu a well so that points out it's not

Turbo is definitely leaking and has heeps of play in it I'm not going back to stock here is what I'm looking at 

6boost manifold twinscroll 

GTX 3076R GEN 2 (not sure what housings to get or if x2 waste gates is necessary )

225 walbro fuel pump 

550cc injectors 

Spitfire coils 

Trans cooker

Looking at haltech ecu or nistune 

forward facing plenum 

Pwr radiator 

Its automatic and its staying that way so I know I need to keep the power around 280kw and even then I'll probably kill it so what auto trans options do I have other then a rebuilding the current 1 any 1 put a 5 speed or 6 speed auto out of something elce onto a rb25?

    • 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.
