Heard of this , but this one seems to be rand new. I think the remanufactured ones are sold in AUS (i would not buy re manufactured personally)

This is exactly what I was looking for.

There are common upgrades for the RB ( z32 afm , splifire coils etc)

What is the common upgrade for injectors (am I to assume its the 550 Nismos?)

Dont really want to go top feed and have to mess around with brackets. Is there anything else with a proven track record that is drop in?

I started off with nismo 550 but the reason why I did end up going with these 5omotorsport 1000s was due to nismo not going bigger the 740 and theres nothing else really out there in 1000s that will drop straight in as the next step is mucking around putting top feeds in but is a hassle if you still run the standard plenum. But yeah as I said mine have been perfect so far and they idle like the stock and nismo ones did so no problems there.

but but...you said.... but...

Can only speak about z32 application but part number is same.

I do not like the way that they use an oring on an oring to seal the injector into the bucket. That's the first/main issue (again, in z32 application).

Second issue is they cost me 2 engines (1 forged) because 1 was not flowing as it should at higher duty. Issue was masked by the others showing 'safe' afr's.

Not specifically the injectors fault, but I blame them :P

Nismo 555's have been used in z32 for aaaaaaaaages. They are the benchmark for oem replacement, upgraded injectors.

New style nismo 615s have superceeded the 555's AFAIK.

:(

the next step is mucking around putting top feeds in but is a hassle if you still run the standard plenum.

The short 1000's fit under the plenum, no hassles there. Even the longer 3/4 length top feed injectors will fit, depending on the rail. The hassle is getting a reg to suit, as the stock reg won't screw into the rail. (unless you use a stock Neo rail...)

If this is stumping you, stop modifying the car yourself, as it is very basic work imo. Just pay someone to sort it all out for you.

The question is not whether you can or cant the question is if you have an option that will work out cheaper bolt straight in no need for new connectors rails regs why would you bother going top feed route. $650 will get you 1000cc delivered that bolt straight in and do the job well.

this. I'm not going for anything to crazy - Im looking for power levels most Skylines owners would laugh at(230rwkw).... why spend more time and effort when I can drop in side feeds that do the same job for cheaper and less work.

They are doing 350kw on e85 on my setup on my track car so they get put to the test and are performing fine so there is no problems with rhem just cause some high flows are poor backyrd jobs doesnt mean all are.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
