Hi guys first post for me,im new to gtr's.I have just recently bought a r33 gtr from Adam at JEM.It currently makes 343kws at the wheels on 20psi.

My plan is to switch it over to United e85 with an end goal of 400kws at the wheels.IT has a precision 6266 turbo and other supporting mods.At the moment it has an 044 intank,i was thinking of replacing this with a walbro e85 450l/ph pump and replacing 750cc injectors with some bosch id1000s.

I have asked Adam at jem and he said in theory this pump should do the job,but has not personally done it.

Your thoughts guys or experiences would be great.I will directly wired this off the battery thru a relay to get good volts to the pump.I have used the search function,but could not find an answer.

From the last page of the RB26 dyno results thread:

forged bottom end

stock cams and valve springs

metal head gasket with ARP head studs

precision 6266 0.84 T4 divided rear

3.5" dump/cat back

GFB EX50 50mm external gate

1200cc injectors with walbro e85 pump

power fc d-jetro

409rwkw @ 26psi on Caltex eflex E70, at the limit of stock cams and injectors

At 13.5v and 40 psi rail pressure it advertises 430l/ph and on 12v at 40 psi it flows 375l/ph.I plan on running a direct feed to get near 13.5 volts.So at 40psi pressure should outflow 2x 044s.I was toying with the idea of the bosch id2200cc injs.Thanks guys

Not sure on that one piggaz,i think I will go straight with the bosch id 2200cc or similar brand.Car has haltech platinum pro plug-in,should handle the big injectors ok.Thanks guys.

Have a gander at my attachment.

I wrote a pretty simple spreadsheet for calculating and comparing different fuel systems for my car. Obviously it's to suit my setup but could be easily tweaked.

I have highlighted all of the cells you need to update then see sheet 2 and graph's it all out.

IE set the highlighted cell to your desired base fuel pressure. write out your hp and boost based off a close dyno sheet. in my case when it was tuned for bp98. and then fill in the injector flows and corresponding pressures.

with this info it tells me that my injectors are too small for me to convert over to E85 and keep my same HP. unless I either run a 70PSI base pressure or go about an 80% duty.

thanks ss8 gohan,will go with the e85 450l/ph pump.Still tossing up on the injectors.Tuner thinks 1000cc ids will do,but a lot of guys on here think the 2000cc are the go.Most suppliers will warrant the 1000cc with e85 but not the 2000cc,Will do some more research.Thanks all,for ideas and tips.

    • My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.
    • There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.
    • I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.
    • Yeah - I mean, go the other way. Smaller range. Not larger.
    • To re-cap, I bought: https://www.alibaba.com/product-detail/Lsailt-8G-Infiniti-Q50-Q60-2014_1601171829627.html?spm=a2756.trade-list-buyer.0.0.2cd476e9FTIlKE As you can see, if I bought 20 it was $653, but I bought 1 so it was $1,170. I was very tempted to buy 2 and resell 1 at 25% cheaper. @MBS206, I am not sure if they do a Kluger one, here is their list but it might be there under a global model name: http://www.lsailt.com/product/android-interface?page=1 Keep in mind these full android replacements have basically all the bits a phone does (cpu, ram, storage, wifi, bluetooth, usb interfaces) other than a screen (it uses a host), thus the $800+ cost. Android Auto screen mirroring is MUCH cheaper as it's just a cut down shell, input mirroring and output mirroring BTW I also need that "screen off" feature, it is much harder to see wildlife even if a dash is reasonably dark. Both the Fuga and V37 have display off buttons for night use, they just come back on for a second or 3 if you interact with it, eg skip a song.
