No, its the Garrett version, I cant see paying near double the price for 100-200rpm worth while, rather spend that money in more usefull places.

I think the biggest thing with a T04z is if you want it to run nice on the street is to use a well design twin scroll manifold and use a smaller A/R turbine, I find it far easier to drive because it rolls into boost much smoother than the GT35, top end responce on the track now is also night and day, I chopped off 2 seconds around our 1.20ish track swapping to the T04z, on the street you can feel it powering up at 3000rpm by 3500rpm its at 7psi and by 4000rpm its on fire, suits my driving style perfectly.

hi all,

Car is back on stands, engine and driveline are out.

Have to go to Bunnings to get 1 engine stand bolt!! (seem to have lost one)

Then it will be getting stripped down.

Surprising how easy it is to pull an engine out once you have done it a few times.

Car was up, engine and box was out in an hour lol Probably could have been quicker but i spent 10mins trying to get the circlip off the shifter with a set of long nose pliers :)

OK just an update.

Rather than fix the damaged head (which looks like it would cost alot to weld up and grind) i purchased a whole RB25DET long engine and will be using the head off that.

But everything in that head will be replaced ie: Valves,Guides,Seat,Valve seals the lot. So it will be a brand spanking new head when its all finished :)

I also bought new pistons (Mahle) and i cant believe the quality of these things! ( :( Steve-o )

Ultra light, Teflon skirts, carbon rings very nice indeed.

And i have sold the Poncams and replaced them with HKS items in256 8.8mm ex264 9.0mm Just so i can squeeze a little more out of my setup.

Things have been rather busy so the bottom end is still not stripped down. Hopefully next weekend we will get cracking, we now have 2 engines to strip :)

Where is the best place to get Mahle pistons for a Rb26/30? My engine builder wants to use CP but I'm keen to check Mahle out.

Matt

you'll be extremely lucky if you can find a set in the country. best bet would be to source them from the states

i bought my set from http://www.importperformanceparts.net/

tho they are bit more expensive with the current exchange. tho fairly cheap still.

they dont list a price, but trust me when i say its the cheapest i could find!

Hioctane check them out where i purchased mine. Also mahles arent & easy piston to fit they require a lot more mods to fit as they hit oil squirters have to be spaced to fit properly. they arent like your cps or arias that go straight in & theres something else as well cant remember but overall once there in there nice. They are prob one of the best piston around.

You sure thats the way with rb26?? i recall something about sr20 needing to be notched. but the rb26 were ok.?

Yeah im sure about the 26s have somethings that have to be adjusted to fit the mahles. Ill ask andrew who built my engine & let ya know. something about skirts hitting somewhere & something else. But like i said ill ask him & let you guys know

That's ok, my Rb30 doesn't have oil squirters. Are the rings ok if you can get them in without breaking them?

I would think very carefully about that. RB26s also have oil squirters... if their RNN14 pistons foul the squirters there's a good chance they don't clear the 26 ones either. i would check it very carefully. :P

    • 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.
