hey gusy/girls.

I'm looking @ upgrading my stock injectors with S15 injectors as i been told they are a direct fit to R33's?

Is anyone currently using S15 injectors? I'm curious to find out what the s15 injectors are rated at? ADM and JDM injectors...

What are the R33 stock injectors rated at? 330cc?

Any help would be greatly appreciated.

regards,

Anthony

Ignore anything you've read about ADM vs JDM variances - there is none in that regard.

The difference in flow capacity comes from whether the vehicle was fitted with an auto or manual transmission.

MT = 450cc/min - terracotta brown colour

AT = 370cc/min - purple colour

R33 spec RB25 = 370cc/min, exactly the same as the S15 AT.

Flow rates are @ stock fuel pressure. IMO the S15 injector is a good bolt in upgrade provided your ECU can be adjusted to recognise the different flow capacity. Same situation for upgrading the AFM really.

Hmmm i got a set of 6 S15 "RED" Injectors from the Sr20 Turbo manual and i was also told they were 480cc.

i was also told they direct fit RB25DET and the older Sr20 S14 and RB25 are the same injectors im sure.

i had to compare them as i was going to get RB26 items 444cc.

In other words yes the fit and there bigger then standard

100% correct info.

Forget any other junk you may have heard, this is the right information.

The ones you want are a redish/brown/terrocotta colour.

If they are that coulour, you're set.

There is also, somewhere, a super bright red ones.

Don't get them.

I think they were out of something different again.

250cc or something??? (a 96 auto 200sx maybe?)

There is an old thread somewhere on these where i've added pics etc and values for the Power FC.

I've done the 8, sold 2.

Still running them after more than a year.

Put em in myself, no issues.

Running a HKS2535 and they hit low 80% on full throttle.

ebay, all the time

the stock r33 370cc injectors are said to flow to 410cc by the highflowing experts, and that said, the 450cc s15 injectors flow to 480cc

if you have trouble sourcing a set of 6 x 450cc talk to david at deatschwerks usa.

    • What an awesome idea to fit the facelift Lamborghini Diablo headlights. They are a perfect fit!
    • An update regarding the registration with the DVLA I sent off the paperwork the day after I collected the car from the port, two weeks later it was all returned with a letter explaining they have rejected the application. This was because the cheque was £20 short for the road tax (I used a price list I found online). Nevermind it is what it is, it was sent back to them the following day with a new cheque. Fast forward another 2 weeks or so, I called them for an update to be told it had been rejected. Yesterday (16th September) I received the documents back along with another letter, this time it was because I didn't put an X in one box on the V750 (personalised number plate certificate), which declared that I had the rights to the personalised number plate. Why this wasn't mentioned in the first rejection letter, I don't know, but it could have saved this headache. The documents were sent back today, so fingers crossed third times a charm and it'll FINALLY be registered on the road just in time for the bad weather (woohoo!) To cheer myself up I lowered the front 25mm, was sick of seeing it sit like a monster truck. No idea how much clearance I'll have getting on and off the driveway, I'll worry about that when I can actually drive it
    • You're going to miss not worrying about rust in the strut towers like the Skyline shitboxes out there
    • A few little updates that weren't filmed due to not taking long to do or not interesting enough for their own video. My new K&N Air Filter arrived, I went with an RU-4180 which matched the dimensions of the universal cone filter the car originally had.  The battery had gone flat, while that was charging I tidied up the spaghetti wiring at the bulk head and down the sides of the engine Next job was to swap the stereo The Kenwood harness had the female ISO plugs cut off and the male ISO plugs cut off the adaptor loom and joined with bullet connectors. I ordered in a repair loom through work and re-did it all. New Kenwood unit installed (Android Auto, DAB, Bluetooth, Reverse Camera) The bonnet/hood gas struts have been poor since collecting the car. I couldn't find any suitable replacements locally so took a chance on a pair from AliExpress.  The originals don't use a retaining clip to secure the cup onto the ball fixture, would explain why I struggled for 10-15mins trying to pry off the cups. The ball fixtures unscrew using a 12mm spanner, new ones are the same size. Sadly no photo of them fitted, you're not missing much lol The dished Momo steering wheel got replaced with my Momo Tuner, turns out I ordered counter sunk bolts for the horn trim ring (like they normally are for the steering wheel) instead of allen cap (flat seat)  A terrible photo of a Quaife style gear shift knob I've had stashed in my tool box for many years after purchasing the incorrect thread size (I can see a pattern emerging with ordering incorrect parts...) Also threw in a cup holder and a (empty) Boss Coffee can, because why not  
    • GT-R clearly the better choice! The 300 is certainly not insaly fast but has a decent amount of poke. Does a nice little drift around the corners with a decent amount of throttle. It's VERY predictable in a slide too.  Feels so progressive! People probably presume there's a 25 year old driving it based on my behaviour this week! 🤣
