Hi, I am about to purchase a set of SARD 550cc injectors from the NenGun Performance soon, do the injectors are straight fit into the RB25 ? Or I need to get the collars for them as well? Does anyone have purchase any SARD 550cc injectors from Nengun performance before? Do you have pay tax? and how much? Thanks

That are a "straight fit", but they are a pain in the arse with the collars that you need to use to get em sitting right.

For the extra few $$ get the Nismo 700cc injectors. Straight fit without issues.

i didnt pay tax on my Nismo ones through Nengun, i was lucky.

Thanks for the reply guys. How many kw will the SARD 550cc injectors to be max out? I need something can support 250-300kw at the rear wheels. So 550cc should be enough to handle it? How long normally will take to get your goods from nengun once u paid and place order? Or does any1 have a set wanna for sell in syd?

i got some 550cc injectors shipped form the US for just over $500 all up ..

see http://www.deatschwerks.com/

i got some and they plugged straight in, no fussing, no mess, and running 240rwkw i never see more than 50% duty ....

hell, 660cc are only 470 USD for 6 !!!!

easy choice really

Ditto, but not installed in anything yet!

I got the 550cc yellow top Nismo injectors and they are a direct fit for the stock RB25DET fuel rail. I got them through Nengun but I had to ask for them specifically.

I got the fuel pressure regulator for the odd $150 as well as it was recommended by a few well known workshops.

What is the spray pattern of the of the deatshwerks injectors? Is there one hole or multiple holes?

Tang0: What mods you have done on ur GTST R33 to get 240kw on 13psi?

Thats pitty, should post earlier (but thanks for telling the web site), I just ordered and paid for the SARD 550cc injectors from Nengun. Should receive them in few weeks time. Did you guys pay any GST/tax when you receive the injectors?

Currently, I am putting a GT30 500hp turbo on the GTST R33 with SARD 550cc injectors, Walbro 500hp intank pump, custom manifold, 3inch exhaust, bigger cooler, Either Microtec or Haltec computer. Hvnt decide I should put a regulator (aftermarket) or not. What hp (at the wheels) I should see and on what psi? Is any1 running similar setup that I hv now? How strong are the factory internals?

Cheers

not for the RB25 stock fuel rail.

at least not a few months ago.

700cc's wont make a difference anyhow. They are there if you go for more pwoer later  :D

Yes, Nismo have 550cc injectors for the stock rb25 fuel rail and Nengun sell them. Have been doing so since last year :), trust me i was looking.

Tang0: Thanks for that. I know Dave as well, he is a good tuner !

2BNVS: Did you pay any GST/Tax when you recieved the injectors? So you will need the collars to fit the SARD 550cc injectors (because on the nengun web site, it didnt show any RB25 550cc injectors collar, only on SR20DET)? I think I better email them to remind them to send the collars as well. I dont wanna end up to wait so long.

Cheers

yep u need the collars, when i originally ordered the injectors it said it came with collars but it actually didnt, brent said it was a mix up because the rb25det was the only exception, so i had to buy the collars seperatly which is done now, on the site they should have them, they will be the collars for 63508 injectors which are 550 sards, which also fit s14 and s15 200sx by the way

oh and no i didnt pay any extra tax stuff, ive bought many parts, ecu, avcr, injectors, dash, cam gear and never paid extra...

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
