R33 Stock Side Feed Fuel Rail And Fpr? For E85, 400rwkw

[HIKAR1]

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.

[HIKAR1]

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?

...or you could buy a new top feed rail and modern top feed injectors.

I almost can't believe you want to run biggish power without the best fuel injection available.

[Scott Black]

Well not the best fuel injection available, the best affordable availible as drilling the head, fitting some dfi injectors and a high pressure mechanical pump would be the best available

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

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

[Blackkers]

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.

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!

[hypergear]

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:

[chiksluvit]

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

[colourclassic]

Would Nismo 740cc injectors be alright/compatible with e85?
