s15 injectors

[DonDonati88]

I should have no problems hitting 325rwhp with only 440cc injectors off an S15 engine, right?

Also, anybody EVER get there engine (that ordered a few weekes back) from Flash Options?

[I H8 UR DSM]

your question isnt very specific....you have an S13 and you think if you put in 440cc injectors you will have 325whp? if thats what your thinking, then No would be the answer (Or yes, you would have a problem).....

[DonDonati88]

Obviously that was not my thinking... (but can understand since a lot of questions on this board are idiotic). My question was can 440 cc injectors facilitate or "handle" 325rwhp. Or would I need to go up to 550

[I H8 UR DSM]

it would be getting close to 100% duty cycle around that level....since 550's will start to max out around 400whp, i think the 440's will be maxing out around that level, but you should be ok.

[DonDonati88]

OK, THNX

[DonDonati88]

oh yeah and to hit 325rwhp with a stock s13 redtop turbo, is that impossible? Or would I need to go turbo upgrade?

[Redline240]

I don't think the T25 will even make it to 300rwhp, the T28 maybe.....so yeah a turbo upgrade is in order.....

[Daunttless]

The T25 will not make that much power.

[Redline240]

how much will it make? 260rwhp?

But you shouldn't have any problems with the S15 injectors, considering they are 480cc, not 440cc. The 440cc injectors are the top feeds found in the pulsar GTI-R. The S15 has side feed 480cc injectors.

480's are ok for 325hp. The turbo, however, will have to be a T28 or better to make that kind of power.

[DonDonati88]

Ok but I will be able to make 260rwhp, 300hp at the crank with the T25 right? I wanna be pretty damn close at least. I heard in Super STreet that this can be done with 3in dp, 3 inch exhaust, 255lph high flow fp, intake, and an ECU upgrade. What do u think?

Also are Iridium plugs worth buying? Theyre supposed to add slight performance gains in turbo applications. What gains if any has it brought to a T25?

[DonDonati88]

[DonDonati88]

bump...answer my question someone...

[1bad180sx]

Yes, iridium plugs are good. Try to get NGK Iridium. (as repackaged by companies such as Trust, but also sold directly from NGK)

I don't know how much power you can make on a stock turbo. Sounds like you want a T28 off an S14 or S15...

go to http://www.rceng.com and use their injector calculator.

Hi!

Are you sura about the S15 injectors being 480 ? I have read this on many places om the internet, but I have also heard 450.

I have S15 injectors bought from Tripel A in Japan, and he said that it was 450.

Did they change them at any time or someting like that ?

Ps. You are not running a GT25 turbo? If you are, give me an email

[DonDonati88]

Well according to the fuel injector worksheet on that website at 80% duty cycle I could reach 350hp at the crank with my stock 370cc injectors!!!! Cool!

Does this sound right pros?

try that website out it's pretty interesting.http://www.rceng.com/technical.htm#WORKSHEET

[themadscientist]

which BSFC formula did you use? Try .65 and I think you will find a much lower figure.

Ok. It just seems like a big step from S14 370cc, or is japan S14's bigger also? I have to refer to the net since we haven't got even one S15 here

But you are really really sure? The guy how sold me the injectors races with an S15 in Apexi Cup and works for a tunning company so he really should have known I think?

A picture of my injectors:

What is Apexi cup?

Does he have a Japanese S15? Or the type of 200sx they sell in Australia?

Well my Japanese isn't that good .. But I think it's this:http://www.apexi.co.jp/cup.html

It's a Japanese S15... But the injectors came from a customer car. Here's his car. Don't know what it says, but its looks ok

I can see 550hp and 2.2 liter, it jives. That wing though, cripes!

[themadscientist]

Your injectors are sidefeed so they will drop in, they could be Nismo 550s but just from the color there is no telling.

Well, it should be S15 injectors and it probably is. But are they 450 or 480 ?

About the car. Do they "need" those big wings on the track since everybody racing there have them?

[KRPSICHI3]

They are 480cc injectors I used them for about 6 months and the hit 100 % injector duty. Hence I purchased 550cc injectors.

Ok! That sounds good! The bigger the better.

Ps. Can you or someone else in Japan do me a really BIG favour and call the company in the first picture? I wan't to know if they still operating. I have lost contact with my contact there, Chikako Nishizaki.

I wan't to know if they have closed or maybe he just have changed work? Perhaps he dont like to answer my email any more? (very long time ago)

Anyway, it would be great to know! Maybe a new email to them?

Please?

[SJN]

Anyone ?

[DonDonati88]

No. :bshake

But as you can see no one like's to do someone else's dirty work. :evilhaha
