I was able to find a good price on 350z injectors (370cc) and i was wondering if they will work on my vq30de-k(t)

i have a neo to tune and will be getting a walbro but want to know which model i need the gss341 or the gss342?

finally will i be ok with the stock fpr and if not, why?

thanks

 

re the 350z topfeed injectors? if they are not then ou cant use em.

 

Who said they were 370's? IIRC, they're 335's @ 3.5bar. (350z)

300zx injectors are 370's & topfeed.


Yes, they're(350z) topfeed.

I have them in my 03 and I'm not even boosted.

 

If you're referring to OEM 350Z injectors, you already have them. They're standard issue on the DE-K. If you meant to say aftermarket 350Z injectors, yes they'll work.

 

no stock de-k injectors are stock injectors 290cc @ 3.0 bar fbjc100
and stock 350z injectors are 335cc @ 3.5bar

 

^^Was that to me?

290cc @ 3.0 bar ≡ 335cc @ 3.5 bar. The standard pressure for rating injectors is 3.0 bar so technically 350Z injectors are 290cc as well.


The DE-K and 350Z injectors share the same exact part # up to 07/04 production date. The 2004.5 model year and up 350Z uses a different part #.

 

gotcha they are the same injectors just running different fuel pressure.

 

300ZX injectors are side feed, but I think you knew that - probably just a typo.

Anyhow yeah, the rest of what everyone else said about them being 335s @ 3.5bar is right on.

 

so than what fuel pump do i need? gss341 or gss342?

if i keep my stock injectors with a better fuel pump will it improve my fuel delivery?

I need more fuel for more boost!!

 

not by just replacing the pump, if you want to keep your stock injectors a TEMPORARY, not so effective way to help would be to raise fuel pressure via an AFPR. It would be better than what you have now, but no certain way to tell you if it would work for your particular setup/ boost level. In other words, its better than what you have now, but I wouldnt recommend it if you can get a set of bigger injectors.

Dont half-axx this and get injectors. Do it once, do it right. Dont risk blowing your motor. You already got close to it running it so lean before Mr. Piston noise, lol - no offense intended by any means. Its just that it would suck to blow your engine for real over this. Get bigger injectors so you can completly forget about your fuel system, and be confident its gonna hold to your setup. Peace of mind>*
