Lads i need some advice, did a bit of searching and didnt come up with much.

R32 Gtr running t04z with all supporting mods

fuel system is 850cc tomei injectors,sard reg,hks twin feed rail, big sx fuel pump with surge tank and gtr standard pump as feed

Now its currently running at 19psi on pump fuel, and i want to get a race fuel tune for an event that is coming up.. i was planning on running e85, and after doing some research have come to the conclusion i will need larger injectors(some say as big as 1600cc!)

so do i go bigger injectors and run e85, if so what injectors should i look at? plan is to push the t04z up to around 26psi.

or do i use something like ERC, VP racing, ELF.. and if so which brand/model do you reccomend..

i wont be doing many events a year with this car, so i dont mind spending a bit on racefuel for a one off each year. also what hp should i expect with 26psi and your choice of fuel?

thanks in advance!

do what i did and do a fuel blend. I went with 50/50 E85/PULP and it works out to be 42.5% ethanol content. very easy to mix since the ratio is simple.

power gains on my car went from 320 rwkw at 20 psi to 360 rwkw at 16 psi plus a load more timing and reponce. i didnt want to upgrade my injectors so this was the best result for me without having to change a single thing! Pretty stoked with it over all!

personally i would go this over some expensive race fuel.

cheers simon, this sounds like a good alternative. how come you didnt wind it back out to 20psi? injectors maxxing?

nytsky 1000cc was going to by initial choice but after speaking to the fella who will be tuning this, he has advised to go with 1400+

Quick rundown on my setup, any holes that need to be filled lads?

standard gtr lift pump

2.5l surge tank

sx fuel pump ( Supports carbureted engines up to 1300 HP and fuel injected engines up to 1000 HP at 45 PSIUltra high-flow rates exceed: 80 GPH at 12 volts and 45 PSI, AND 120 GPH at 12 volts and 10 PSI)

sx filter

-8 teflon from pump to y piece at engine bay.. splitting into two -6 either side of rail

-6 teflon return to sard reg

-6 teflon reg back to surge

injectors are 850cc tomei's.. too small..

what brand injectors? been looking at id2000 and bluemax seem to do some good sizes too.

what would you expect a rb26 t04z at 25-26psi stage 2 hks 272 cams running e85 will make?

      Duncan's V37.......race car?

      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

      Duncan's V37.......race car?

      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.
