hi guys,

i read somewhere that the sr20det injectors will directly replace the lower cc rb25det injectors. both being side flow injectors... rb25det flowing only 370cc/min and sr20det flowing 420cc/min (stock). can someone confirm this.. if this is not true, what about a subaru wrx injectors or a rx7 side flow injectors? i'm just looking for good cheap higher flowing injectores i can scavange from other engines.

thank yall in advance.

JDM 200SX S15 manuals have 440 cc injectors, all others have 370 cc's same as RB25DET.

As far as I know RB25DET injectors are unique in their dimensions. For example, Toyota 1JZ and 2JZ injectors are side feed, but you would need to make adaptor rings for them fit the RB25DET inlet manifold. The SARD side feed injectors are actually designed for 1/2JZ's that's why they need adaptor rings.

From what I have seen WRX's come with at least 3 different styles of injectors, 2 different top feed styles and one side feed style. None of them are the same as RB25's

If you are going to the trouble of making adaptor rings, you might as well use top feed injectors, plenty to choose from then.

:teehee: Cheers :laugh:

manual turbo s15 200sx's, australian and jdm versions both have 480cc injectors (less depending on quoted fuel rail pressure).

hey guys,

thanx for the info.....this means i need to find 1 and a half s15 engines to scavange these injectors from... have you guys heard about the rx 7 injectors???

also does this mean that if i could make adaptors i could plug and play those 1jz/2jz injectors not worrying about the wiring and voltage...?

    • I drive the Tiguan much harder than the Skyline in all conditions, because it just grips and hooks, unlike the R33 shit box
    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
