Sr20 Injectors, Do The Fit...flow More ?

[fresh]

hey guys

need a bit of help, i can get my hands on some SR20 injectors and i've heard they flow more but i'm unsure, do they fit and do they flow more ?

if so is it worth upgrading, how easy would it be to adjust the PFC tune ?

cheers

Nope, same size as the R33 injectors.

[Tommyk]

i would think they would be bigger, seeing as there are only 4 of them

which model SR?

S13 sr20 = 370cc

S14 sr20 = 370cc

S15 sr20 = 440cc

hmmmmm interesting, i'm assuming r33 ones are 370cc then so S15 would give me an extra 70cc which should be enough, i'll look into it further

If you are looking at S15 injectors, you want the ones from the Japanese S15 (I think they have a brown top) as they are the 440cc ones. I think the Aussie S15 has 370cc injectors.

I went thru this a while back for my r33

There was a thread on this approx 12 months ago with part numbers etc.

The S15 "manual" turbo injectors which have a brown top are 440cc (you may read somewhere they are 480cc aswell, they have been tested at 440cc)

S15 "auto" turbo injectors are 370cc purple top, the same flow as r33

You can get the manual S15 injectors out of a Aussie or jap import motor, their the same.

They will give you a 19% gain over the stock R33 which should be good for upto 250rwkw

They sell for $300 set of 4. You can buy to sets of 4 and have 2 spare, or I have 2 left over as I sold the other 6 to another forum member. $150 for the pair

There is always some for sale on NS.com

yep darren is spot on, the s15's should be a direct fit

and then you just need to dial in the correction size into the powerfc (these wont work with the stock ecu) and away you go
