For all those of you who spend time and money for your N/A R50, i have good news.
The stock R50 injectors are very small, at 178cc/min@3 bar (Bosch part number 0280155991). Anything more than a full exhaust system and intake, like a camshaft, will take them to 100% duty cycle at high rpm if remapped, something not good. Also it's not safe to run an R50 with a camshaft and/or ported head without a custom remap, as it leans out at various rpms ranges, depending on the camshaft characteristics.
Until now, there were no available larger injectors for the R50, either the available ones are too larger for a 1.6l normally aspirated engine that will rarely make more than 150-160bhp.
The solution to this is a set of Bosch EV6 injectors, part number 0280155865. They just require two small fuel rail spacers to fit, and the plastic engine cover has to be removed, which i consider is minour. These injectors flow 267cc/min @ 3 bar. They retain the dual cone spray pattern, at a 20 degree angle instead of the 15 degree stock angle. The axial deviation angle is 0, just like stock. They require no adaptors, as they have a uscar type connector, just like stock.
These injectors are ONLY recomended to R50s with at least a camshaft fitted. Not recomended for cars with just an intake, exhaust etc, because they are not needed. They flow enough for any power output a street normally aspirated R50 engine will make, and are not too large like other injectors out there. This means they will be calibrated easier, and will respond much better at low engine loads and idle.
The good news are, these will work even without a tune, although i will NOT recomend this. The closed loop will adapt shortly to normal air/fuel ratios, but it will be very rich at open loop.What i want to say is, you have fit them and drive to the dyno, to have your custom remap done, without a single problem. Only the first startup, where it will take a minute or so, until it adapts with the injectors on.
The part numbers are mentioned, so anyone can have them imported from US. I am also able to supply them at a very competitive price, along with the fitting kit, anyone interested just pm me.
Also a few photos and a video showing the behaviour of the ecu with these fitted just a few seconds after the install.
