I can't remember exactly but there's a couple mm difference between stock and these 550cc. You just need a small washer to angle the fuel injector rail very slightly. I wish I had pics of it but haven't had a chance to get under the hood. When you see it, it'll make sense. It's just a tiny difference. These injectors are almost perfectly plug and play though, and they run butter smooth with a good tune. It's nice to not be running 100% injector duty cycle. 🤪This is my Unbuild Journal and why we need an oil thread

But he’ll yeah these injectors are night and day over stock bs. Hassan was almost completely able to fix the drivability issue I had before because he had to detune for the lack of fueling from the stock injectors.
With porting, schrick 280/272 cams, upgraded and lighter single groove valves, and the 550cc injectors the car is still making power on the dyno at 8600rpm without drop off and it feels considerably faster from 3k+. With stock injector the power dropped off at 8200rpm and the car drove like crap imho.
VF engineering uses this same injector with their stage 2 supercharger kit and they use spacers to raise the injector out of the throttle body but have you drill out the fuel rail bolt holes because it will not line up to the factory points as is.
If I get everything this week I will take some pics of what I end up with install wise. But I’ll be honest this has been a royal pia because nothing is direct plug and play. And EV1 injectors are antiquated tech so you’re dealing with custom fitment for the EV14, but the car will drive so much better.

I have these from McMaster that my friend BbrTuning is running with these injectors
I’m going to probably just run 1 though because if you go too high the electrical harness puts way too much tension on the injector because it’s smashing the head and torquing the injector. VF also says the pig tails need to be slightly released to lessen the tension which I’m going to try as well. You can only do so much though before the harness just flops around since the injectors are what keep it secured.

This is a great thread! I’ve been wondering why my NA build hasn’t been able to make peak power than others have been able to and I think the stock fuel injectors are my limitation.
Couple of questions.
1) Any issue using the stock fuel pump and FPR for the larger injectors?
2) what was the part number for the washer on the injector?2005 BMW M3 ZCP Black/Black - HTE Tuning | Kassel CSL DME | 288/280 Schrick Cams+DLC Followers | Lang Head | Dinan TBs | Bosch 550cc | Radium Fuel System | Karbonious CSL Airbox+OE Snorkel | SS V1 Stepped+Catted Sec 1+Resonated Twin Pipe+Race | 3.91, 3 stage clutch | FCM 400/600 | Vorshlag Camber Plates, RSM | Rogue ASP | AKG FCABs, SFBs | TMS Front Sway, Camber Arms, Monoball RTABs, Pullies | Mason Race Strut + X-Brace | AS 30% SSK | SPAL | Redish Plates | Turbo Toys V2 Hub | WPC Rod Bearings

Can anyone share their injector latency offsets for the Bosch 550cc injectors? Ever since I swapped these in, I'm running lean at idle and low throttle. If I compensation on the global scalar I'll end up running rich at mid throttle inputs (fuel trims go to -20%). Fuel pressure is a touch low (65psi at idle with vacuum hose attached), but I don't think that would cause these issues. The biggest tip off is that when I add 10% fuel at WOT it does not translate to a 10% shift in lambda values according to my wideband.
