ok fellas i need some help because everytime i think i found a set of injectors i find out they don't fit. I was wondering if i could gather a full list of aftermarket injector options for my 2000 max. I have tried searching but all i can find is options for the 5.5 and 4th gen. Any help would be appreciated.

 

bump bump bump

 

There is NONE for the "VQ30" in your car, HOWEVER we use the same injector as the VQ35 350Z. Therefore, any 350z injectors will work just the same.

Question is...do you want Plug-N-Play(expensive) or splice-n-spacer(not expensive) and what size do you plan to run with your engine management?

 

I got the 510 and they pluged right into the harness and fit my fuel rail.

 

wow i sound noobish......wtf are 510's. 510cc?

 

can u ple tell me how to make the 350z injector fit 4th gen?

 

the 350z injectors only fit 5th gen because they are top feed. The 4th gen injectors are side feed which means you can't make them fit. You can use the injectors for a 300zx.

 

'95-'96 only. And you want the TT ones if you want 370's.

 

You sure they're 510cc Gabriel?

I hear they're actually ~470cc, since they're rated at 51psi. Probably not a big deal, but just something to take into account when tuning.

 

i saw some 555cc injectors on the hks website for the SR20det motor for like 215 or something....would those fit those? someone told me that the sr20det injectors work.

Injectors for the 95-96 VG30DE, RB25DET, and SR20DET will work for 4th gen fuel rail. It is just more common for people to get them for the Z32 b/c the SR20 only has 4 injectors and the RB25 is pretty rare.

The VQ30DE-K has a different fuel rail though.

 

So what injector can the 99 Max use if only the 370cc from a TT 300ZX can only be used for 95-96?

 

where can i find the splice-n-spacer ones???? bosch?
i plan on doing the dek intake manifold swap

That's a GREAT price...I've seen them go on eBay for more and used are around that, but those are new.

 

thnx but 750cc are more what im looking for

 

Whoah~!

I can PM you where some of those are, but you'll need to make your own spacers.

 

thanks.. i can figure out the spacers

 

I have rough measurements on the RC spacers and I hear they are pretty much the desired size.

Shouldn't be difficult to make at all.

 

yeah man let me know

 

I would prefer 370's. I would be using these with my safc and a aem FPR. That would be enough for 10psi wouldn't it? Also what brands are available for these in plug n'play.

 

Power Enterprise 380cc. I'm still hoping someone will verify flow on these, since a RUMOR has them being flowed at 52psi, which would make these actually ~350cc.

Buy at gruppe-s.com for new $870 or around $670ish for slightly used on my350Z.com. Last I saw there were two sets available. Here is one:

370s are maxed out at 10psi

 

Yes, around that if you use stock fuel pressure, but not if you use a FMU.

There is a trade-off bigger injectors vs. higher fuel pressure, however IMO if you can keep IDC between 80-90% max while keeping peak fuel pressure under 80psi, it's fine.

STOCK fuel pressure 370cc:
DC = 80% ~260whp
DC = 90% ~294whp

80psi fuel pressure makes 370cc-->~501cc:
DC = 80% ~350whp
DC = 90% ~400whp

These are assuming a supercharger recommended BSFC 0.55, 15% manual trans drivetrain loss, and finally roughly rounded to round numbers.

 

They are 510cc Power Enterprise injectors. At $150 per injector.

 

So If I run 370's with JWT program and NO FMU, i will be ok but If I run the 370s at a higher Fuel pressure with the FMU still connected is better ??

Are 370's enough to run with a S/C 3.125 pulley with NO FMU

No, you can only use the injectors from a 95-96 300ZX in 95-99 Maxima.

 

FYI, they're most likely not 510cc, but 470cc, since Power Enterprise specifically "designed" them for the VQ35s fuel pressure of 51-52psi not our 43psi.

Probably not a big deal, but just incase you push them.

 

You're just going to exceed recommended 80% duty cycle most likely, but most here do. I'd use the FMU if you hit 90% duty cycle or above to bring it down.

Yes, look at StephenMax he's running a 3" pulley to 7200rpm with probably the most efficient/lowest boost drop setup here.

 

Does Stephan have his cartech hooked up ??

-matt

 

Not sure what he's currently at FOR THE MOMENT. He never stops tinkering/optimizing his setup, but I believe he ran fine with out it.

 

Thanks ICE, your always helping me out when i'm in a jamb. I will probably have to wait a couple of weeks since my car is getting painted right now.HMMM tasty BMW jet black paint job

 

True dat. Although I think "tinkering" is probably more descriptive than "optimizing".

Without the fmu hooked up my afr is in the mid 12's after 5000 rpm and it runs just fine.

 

CAI, clocked SC, 300Z elbow, 3" discharge piping, Pathy TB port matched to IM, LM-1 fine tuned, etc.. You've got the most optimized, ie lowest boost drop setup, out of ANYONE here.

You are a spitting image of my philosopy Stephen Max, ie stop throwing TONS of parts at the setup to make more power and just fix what the bottle-necks are for what you brought. I know guys willing to swap turbos for theoretically more power, yet they won't even dyno tune the setup they've got to maximize the setups potential.

I think engineer nerds like us, just look at things differently. I can't wait until you buy you know who's, turbo kit.

 

Just bought these injectors. Now I have to figure out how to convert my whole setup to E-manage....

Anybody with experience doing a s/c setup with e-mange on a 5th gen, and willing to answer the occaisional dumb question?

 

for your gen, bigdogjonx had the most experience. he was t/c though and now has a corvette.

pm him or im him for the most info
