Fuel Injectors In Rb25det (neo)

[Bronx]

hey all, i tried searching for some advice on this, but nothing found. trying to get some larger injectors for the rb25det neo, and been loking at some sylvia s15 injectors, dont want to spend oh so very much cash, im just looking at pulling out about 300kw.

from what ive read, the neo injectors are about 250cc and the s15 injectors are 480cc. so im opting for them, found some new ones from overseas a set of 6 individually bought ones will set me back 300 bucks.

some people have told me they will fit straight on, but im not 100% sure. anyone know????

cheers

aren't S15 injectors the same style side feeds that the R33 use's? so they would be a direct fit upgrade for the S1 Stagea. if you have a Neo motor, so a S2 Stagea, the injectors are top feed and the S15 ones are not a direct fit. oh and stock neo injectors are 370cc.

a couple of options if your not looking spending $1000+ on a set of jap brand injectors e.g Nismo. you could get your stock ones hiflowed, or you could look at getting a set of the siemens/deka injectors, they are basically a direct fit, you just need to replace the injector electrical plugs on the injector loom with ones that suit the siemens/deka injectors. when i upgraded mine i went for a set of 600cc Deatschwerks injectors, and they were a direct fit. from memory they cost between $600 and $650 to my door but the exchange rate is so good at the moment they could be even cheaper.

why not look at a set of GTR injectors? they are top feed and from memory 440cc, but for 300kw may be getting close to making out, so i'd look at 600cc ones mentioned above

because even though GTR injectors are top feed, they are a different style to the neo injectors. neo injectors look the same as XR6T injectors, and i believe they are close to the VQ engine's injectors i.e 350z, M35 Stagea etc.
