I'm running them in mine with nistune. only the 550's though. Idle like a dream and just pulled 291rwkw on e-flex (e70) with plenty left in them..

as long as you can adjust the Injector latency (the "turn on time") then they'll be jsut fine

And I'm positive you can adjust this on a powerfc!

Thanks. I am also looking for 550cc injectors. Where did you get them from and how much. I will need the other type of injector plugs aswell with these?

[Randon_I_Am]

i got them off a bloke in qld (i think)

It was just off ebay... around $500ish from memory

And yes you'll need the plugs, and colder them onto the existing loom.

[Randon_I_Am]

these are the exact ones i got

just email him and ask for 6 instead of 8, tell him it's for the nissan and he'll chuck in the connectors

$71.50 each. for $429, great price!

I bought this same kit but in 650cc. Running a nistune, not a problem

I did have problems with the cheap chinese HKS copy fuel rail

Injectors would not seal well in rail. Injectors tops had to be machined slightly to seal (mechanic did this)

Also the ends of rail were not 100% square so fuel in and out of rail was leaking. Had to machine ends sqaure.

Fitted the up to a greddy style inlet mainfols on a Neo 25.

[Randon_I_Am]

yeah i didn't get the cheap fuel rail.

just used the stock one

[jimmy21]

Thanks heaps guys. Is there anyone you reccomend for tuning?

[Randon_I_Am]

someone that know's what they're doing?

all depends on where abouts you are

[jimmy21]

NSW. Was thinking Blacktrack or Croydon. Would you suggest a Fuel Pressure regulator aswell?

[Randon_I_Am]

nar no need for the fuel pressure regulator. But you will need to upgrade your fuel pump if your gonna make good use of the size of the injectors

I've heard nothing but good things from croydon.

I'm in the ACT so i can't really help out much more than that.

[jimmy21]

Yes i already have the fuel pump. Just a 255l/hr walbro intank at teh moment. Thanks heaps for your help mate

[Randon_I_Am]

that same pump and injectors just got me 290rwkw on e70 this morning

[jimmy21]

What other modifications do you have?

[Randon_I_Am]

NIStune

ATR34G2 (Hypergear Turbo), check the hypergear thread for my dyno sheet

3" exhaust

3" intake with pod

fuel system as above

[jimmy21]
