Fuel System For My 25det

[soturi]

Hey was just wondering what people think of this package?

http://www.tweakit.net/shop/product_info.p...roducts_id=5090

I'll be running about 280rwkw on my rb25det

I broke my fpr when i was getting my half cut

So yeah decided to just grab an aftermarket one and this one popped up, any opinions?

Just buy Nismo 555cc injectors, use the stock FPR.

1. Factory rail, fine

2. Factory fuel reg, fine

You only need injectors, which are around $750 delivered.

There is no need to go aftermarket anything other than the injectors, so leave it that way and buy a replacement OEM FPR.

tomei and nismo regs are cheaper than new standard ones

[R31Nismoid]

Trade Nissan should be about the same, if not cheaper.

If i can get an entire RB26 loom for under $700, there is no way a FPR is going to cost anymore than $100-$150.

You'd be up for around $100 to get a Nismo item here so i don't see a difference enough to get excited about

[JonnoHR31]

cant remember exactly but nissan wanted well over 200 for a reg. it was cheaper to get a tomei with the rail adaptop and hoses etc. only reason i wanted a new one is because i busted 3 2nd hand ones in less than 5000km's, each time i didnt know they were broken until it was under full load and leaning out to around 15:1. so i got sick of 15yo shit

I agree changing stuff that doesnt need to be changed is a waste of time, effort and money. I say also stick with stock rail and a stock reg. but I'd go the 740's. HEAPS of head room for basically the same money.

just my 2c!

cheers

+1 for nismo 740s, i have heard from a reliable source they are better to tune than most.

also +1 for stock rail and stock FPR, get trade from nissan it shouldnt be too much. buying an aftermarket has zero advantage other than more useless bling bits you need to worry about at this level.

if your going to run twin external pumps or some BS then by all means go for gold on an aftermarket

If you don't need bigger - don't get them.

Only get 740's if you plan for over ~330rwkw later on.

Otherwise the 555's will do the job just as good.

you can never have enough headroom, that is until they become harder to tune.. then its useless.

in this case i have heard that the red nismo 740s are better to tune than the 555s. that being the SR RB specific red nismo items, not 740s in general.

yet yes, 555s will be enough but for the same price i know i wouldnt think twice.

nismos are easy to tune, anyone who cant make it idle nicely and be economical (provided everything else is in good shape) shouldnt be tuning cars. for the same price i'd go the 740s
