Searched half a day but no luck finding the info.

New setup:

R33 Track Only

RB25/30

E85

Fuel cell -> Filter -> Bosch 044 -> Surge Tank -> 2 x Bosch 044 -> check valve -> Y merger -> Filter -> Stock fuel line -> Stock side feed fuel rail, 1200cc injectors, stock FPR

My questions are whether the items highlighted in red is capable to run 400rwkw on E85?

Thanks in advance lads.

1200cc side feeds? Damn they are using big drill bits these days...

Yes, they should flow enough, although the fpr may not bypass enough with twin 044's (causing high base fuel pressure.) I guess you don't care about what happens at idle and cruise though as it's track only.

Yeah hahaha I just read heaps on the JECS injectors review. A lot of people had issues running unleaded (idling etc) above 750cc, shit latency and poor spray pattern. Aside from those few people had issues brand spanking new injectors stuck running e85 so different fuel different problems. I'm going to flush them after track anyway by running it with unleaded so no big dramas.

With the flow, I can weld fittings on both end of the stock side feed fuel rail and cap off the original entry and exit, run sard fpr if that helps?

Circuit Sports do a side feed rail which I believe is dual entry, but could be wrong

I agree that you may as well go top feed modern injectors, but if you are hell bent on sticking with side feed then I would suggest the circuit sports rail

You'll be fine. It will flow the fuel no issues. Those 1200cc injectors are a bit iffy though.

Many people have had them die and I met someone who destroyed an engine because it failed under load

Not at all man. Sometimes if the stock components are up to the task then there is no point spending the money, same logic as forging a 300hp RB with no plans of bigger power. Decided last night, going to go with:

ID2000 injectors

Proflow top feed fuel rail kit RB25 plenum

Sard FPR

The JECS 1200cc is now stupidly expensive to what it is worth at $800AUD + shipping thanks to the conversion rate.

 

I was making 490rwkws E85 on stock fuel rail and lines. They are fine.

 

Hypergear, sorry, to elaborate some more for people that may google this question in the future. These are on;

1. Stock lines

2. Stock RB25 side feed fuel rail (non modified entry/exit)

3. Stock fuel pressure regulator

4. Injector size?

490rwkw nice!

For the questions:

1. Stock lines
Yes
2. Stock RB25 side feed fuel rail (non modified entry/exit)
Yes
3. Stock fuel pressure regulator
Sard fuel reg.
4. Injector size?
Ebay Junk 5x0 1200cc injectors.

they work, but they are shit

they idle, but idle rich

they are gay, yes..

here's an entire thread I started on nissansilvia.com about them:

enjoy the read... then once you're done, convert to top feed:

and here's your chance to score a top feed conversion kit at a good price

just need to get the injectors and harness separately and you're set

    • Have a vb in honour of the car comming back
    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
