hey guys, thought this would be the best forum to ask to get decent answers. am slowly piecing a E85 fuel system together in my 180sx. so far have the following:

2.5L surge tank mounted under car, fed by a walbro 255lph intank fuel pump. have mounted 2 044 fuel pumps underneath the car aswell.

have a twin entry fuel rail with a centre return which feeds a sard type L fuel reg ... i would have gone something better, fuel lab, aeromotive etc but this part was left over from another build.

will have each 044 running a -6 line into either end of the rail and then the central return via a -6 also. injectors are bosch id2000's

questions are regarding fuel filters. which should i use? i've seen the new earls billet ones look quite good and apparently flow quite alot 175gph, which is heaps for a 044. should i run a filter for each pump in

between the surgetank and pump to stop any crap going through the 044's.. and if i run a filter between the surge and the pump, should i run another pair of filters after the 044's, in between the pump and the fuel rail?

i'd prefer just to run the one set of fuel filters, to minimise cost, and to keep as much crap out of the engine bay as possible.

reccomendations please :).. and also if someone can reccomend what sort of relay/fusing/ gauge wiring to use for the pumps :). i read the 044 draws around 15 amps, so should i use a 20amp fuse inline for each of the pumps, along with a 20amp relay?

and have the relay triggered off the factory fuel pump wiring... ecu is a link g4 plug in, so all factory fuel pump wiring etc is still in use.

thanks!

well at the moment aiming for around 250kw on the stock engine, it makes 220kw on pump now. i've got a built engine for it but not going to put that in untill there is rods hanging out the side of the stock one haha. i only really like to do things once. id1000's and one 044 would probably do it for now, but then i'd have to go and get new injectors, another pump bla bla bla later on. tuner told me that id1000's will be on the limit at around 260ish kw on e85 so hoping that id2000's and 2 044's should see me through to bout 400kw @ wheels?

That is basically the same fuel system as mine except I have a Nismo lift pump.

I use one MagnaFuel inline filter between the 044s and my fuel rail.

This system supports 800hp quite easily on E85 ;) so id say its a bit overkill for your power goals.

ID1000's maxed at 250kw!? How rich is he going to be running it??? ID2000's and 2 044's should do an easy 400rwkw.

from what i understand, for the stock engine. runs f**k all timing to keep it alive, less timing = more heat = more fuel required to keep it cool/same afr's as running normalish timing thus requiring more injector. that's how i understand it anyway.

i'm sure you can all tell me that its the wrong way to do it bla bla etc. but i trust these guys with my tune, and have been using the same 2 guys for years, which both implement the same technique. really just want to know the answer to the fuel filters if anyone has any experience in this

cheers, i'll check out the magnafuel filters now :). i'll never make 800hp haha. but i'm all about overkill, id rather have too much then not enough.

If it's an EVO - 260awkw is NOT the same as a 260rwkw as EVOs are full time AWD.

1000cc are needed to support 270-300awkw in a EVO. Your tuner is correct, don't listen to the other guys saying otherwise.

Also 400awkw through an EVO will be... Interesting. Are you really going to go that far?

Hardcore overkill lol. My S15 trackie is pushing 285rwkw on 1000cc injectors, E85 fed through a single 044 :/

There's a difference between trusting someone with your car and wasting money.

mad, what duty cycle are you on at 285 with the 1000's?

dont' really see the point in going the 1000's when they are same price as 2000's. dont care if it uses more fuel or driveability etc isn't as good, its a track only car.

I didn't read the first post at all :D

Just skipped to the power numbers in latter posts haha.

was gonna say. i even said in a post that i understand evo = 4wd and 180sx = 2wd. but didn't see a 100kw in the drivetrain loss between the two? am i serious about 400kw? in which? evo, yes. 180... it'll get there eventually.

He's planning a 180sx.

+400kw in the evo really isn't that exciting. id prefer the 400kw be in a skyline. evo = boring to drive. 4wd system in the skylines is way more fun, and alot more predictable.

800cc on e85 with a single walbro was maxed on a customers sr20 at 300kw.

U should go the id 2000cc for later upgrades.

wow, thats really good. guys up here are maxing out 800cc on pump at around 280-290kw on sr's

+ is it really going to be better for the tune using 1000cc now then changing to 2000cc later? i just see it as wasting money. as you'll need to retune the entire map for the 2000cc, and buy new injectors again. unless there is some benefit :S?

    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
