s15 injectors worth buying?

Post by **DonDonati88** » Thu Jan 23, 2003 12:45 pm

Hey,

I can get S15 injectors for 230 shipped. I know they are 480cc, vs the s13's 370cc's. If I have a FMIC, exhaust, 3 inch dp, fuel pump, intake these 480cc injectors and an ecu reprogram will I be able to hit 300hp AT THE CRANK?

not on the stock turbo, even at the crank.

EDIT: i would buy them anyway.

480cc+intake+ECU+?? any extra boost? If your not going to add any extra boost you'll only gain like 10-20hp. Injectors dont do much if there isnt enough air to combust with their fuel.

Maybe S15 injector's on ebay? Ive seen them posted on a couple classified's lately.

GT-R and Pulsar injectors are 444 top feeds, S14 are 480 side feeds.

I would have 14psi of boost. And the ecu reprogram alone will add 25 hp...that's what Ken at Enjuku racing told me.

Well depends on what they(who) do in the ECU. I think maybe 25 to the wheels but id seriously doubt an ECU upgrade would yield 25 to the wheels.

you'd be suprised, Nissan goes into "run dumb" mode when you kick the boost up, dumps fuel and it takes out an a$$load of timing. If you re-tune the higher end of the powerband you can gain a lot of HP.

They do it to keep your motor safe, but who wants safe when you could have fast......

here in japan, s15 injectors are 444cc, at least thats what they tell me, i read somewhere that they actually flow up to 480cc, the auto s15 came with 370cc....but i have been told this all in japanese so i could have missed something, but as for the cc thing its always 444cc

Post by **themadscientist** » Thu Jan 23, 2003 12:45 pm

480cc, open up any Nissan manual. They flow 480cc because they are 480cc, that's why it's called a "flow rating". Auto or manual doesn't matter; S15=480, S14 &S13=370.
