Hey all,

Just need help pulling the trigger.

Im upgrading my fuel pump and injectors to run e85.

Ive read through the E85 thread but just need some advice pulling the trigger.

Im aiming for around 400kws in my 33 GTR.

Im going to use the intank walbro E85 pump, should be big enough?

The injectors im deciding between the

BOSCH EV14 1000cc + 11mm Extensions + Plugs

or the

BOSCH 2200cc Injectors + 11mm Extensions + Plugs

Will 1000cc be big enough? ive been told buy the sales team of the place im getting them for they should be?

Or for an extra $200 go the 2200cc injectors. But reading have said they arent as easy to tune or something?

Any advice or real world knowlage of these two in your own cars would be great

thanks

Adam

You need at least 740cc injectors to support that sort of power on 98. Given that e85 needs more than 50% extra injector capacity to be safe, then 1000cc injectors is actually a bit on the slim side. I'd be looking at something bigger, but not as big as the 2200s. There's ID1300 and so on available, yes?

Ok thats what i was thinking, just getting myself confused...

Does that go for the stainless insides of the 1300cc boschs?

Is there really that much of a differance between the standard bosch and the ids?

The ID2000 spray pattern is pretty poor and linearization becomes a problem below 1.4ms pulse width. This causes all sorts of issues with E85 from poor idle control, poor engine response to cylinder bore washing. They work but users need to understand the additonal risk...fuel dilution etc

It is my understanding that any of these Bosch EV14s need to be modified for use on liquid fuels, as they are originally gas injectors. I might be wrong, but that was my understanding.

The 1000's are fine, the 2000's are natural gas injectors.

If ID actually release the 1300's for sale (I hear they are having issues supplying them atm) they would be the best option, until then the 1000's are your best choice, with a higher base fuel pressure to bump them up into the 1300-1500cc flow area. Be wary buying from the US as a warranty from there is almost useless. (by the time you pay for shipping back to ID and wait a month for them to be returned.)

The other option is Moran injectors, not cheap but there are plenty of sizes to chose from, and they spray beautifully, but you will need a 10 micron filter for them or your warranty is void.

Any other options for slightly bigger as those morans are damn expensive

Not for E85, there are 2200cc continental/VDO injectors for petrol vehicles, but I have never seen them used, and they are a little more expensive than the Bosch 2000's last I checked with my wholesaler.

The moran injector fan/spray angle is very wide... I allways wondered if you'd get to much wetting down against the intake mani wall.

Ever seen a set in a GTR?

Not yet, the EV14's are the big seller, the Morans are always too expensive at around $250-$300 each, depending on size.

      Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?

      To be fair - you see the same thing for every clutch. There's always someone making an installation error.
