S15 Injectors

[SexyPete]

Hi i am searcing for a set of s15 injectors and on nissansilvia.com they all say that s15 injectors are good to 200rwkw, i am after 250rwkw and have read on sau that they are a perfect match for that power and completly bolt on to the rb25det. Which power figure is correct and is it just because of the sr20 engine with 4 cylinders not 6 that it only puts out 200 rwkws. just want to clear that up before i get a set.

Yep. The 4 cyl vs 6cyl thing.

On a 6cyl they should be good for around 250rwkw.

I will have 2 spare soon if you get a set of 4 you can buy the other 2 off me.

I bought 2 sets..

yeah that is just cause they are a 4cyl. the stock rb25 ones would get you to 250kw put they would be close to maxing out. the s15 ones are bigger so they should still be pretty safe at 250kw.

make sure you get the jap spec ones, which i think are around 450cc, and should be fine for 250rwkw. they should be a straight swap

just on this note, would u require an aftermarket ecu or would the standard ecu or even an safc b able to handle them?

Standard alone is no good.

Standard with a TUNED safc should be fine

They push approx 20% more fuel than standard injectors so if you only change the injectors, you'll be pushing 20% more fuel on every part of the ECU map.

Nice blackish smoke I'm guessing, less power, and higher fuel consumption..that's if it starts
