Yep they probably tick when the engine is running, most if not all injectors do. Nothing to be concerned about, they all tick.

The ticking means there working, well its more or less the injector opening and closing, thats the ticking. There spring loaded inside, and its the plunger inside of the injector that moved up and down to allow fuel into the cylinder, I think thats where the ticking occurs!

Plunder opens and closes according to the signals from the ECU.

The plugs to the injectors do supply power to the injectors as well as signals from the ECU about how much fuel to spray in to the cylinder, when and in what order. Those signals are made up from various other things such as airflow (AFM or MAP), throttle position (TPS), coolant temperature sensor, voltage sensor, engine speed sensor etc, etc..

Sensors do all the reading (sensing), and the ECU does the calibrating. I think thats the correct wording!

Basically yeah!

Will have to get the car tuned though, so after market ECU, either stand alone or fuel only, or a REMAP of the standard ECU which is starting to get phased in with the R33s.

      Gran Turismo 7 Time trial

      Does this count as a time trial as well? I got all gold in the master super licence (1 lap time trial) and received a McLaren MP4/4 for my trouble.  If anyone else has done this, did you ride the wall right around the first long right hander at Lake Louise snow track to get gold? I couldn't do it any other way... best I could do without riding the was was within 2 tenths of the gold time.

      I definitely get the low power, sporty car to drive to smash gears but not be doing eleventy million miles an hour! It makes all the normal drives fun!   Rev match tune sounds like the funs! I didn't know the NC had a DBW throttle!   As for me, still have the Skyline, it still has the Barra in it. It's been pushed to the side of the workshop at the moment. Pretty much waiting on me finishing the wiring, and dropping new fuel lines in. Got myself an ACDC Tig end of last year so been teaching myself TIG welding to build a few things for the Skyline. The missus wrote off her GTB liberty at the end of last year, and got it back on salvage rights stupid cheap. It's also still registered, so will mean easier for me to take to the track already done most of the panel damage, just playing "clear the workshop" to make space to pull the motor and box out, fix some oil leaks, replace the clutch, and replace a few minor broken things.  Also got a Lathe at the start of the year, which is adding to the annoyance of no space, which is another reason I'm trying to build things to get more space, to get the Lathe back in a final home for it. It's a BIG lathe, can turn a 355mm diameter, and 1metre between centres... Got it at a steal! So between it and the TIG and old MIG welder, I'll be fabbing some fun little shit up But we've had a lot of shit stuff happening at home, so it's slow going getting things done. But one step at a time!

      I love Catalunya.  Got a 1:54.632. The AMG is a hoot.

      I hadn't got that far, my main worry was the connection to the actual calipers themselves. I'm just using new (ish) stock brake lines in the stock setup. I've just had a stud welded to the knuckle that is a little lower than the original stud (so my knuckles have two studs each side) to not have it be stretched so far in previous BBK setups, so the "block" (in the second picture) mounts a little lower for me and I hope I don't need to change anything. I may have even changed the connection to the calipers in the past and have since forgotten I did that. I may not have. Guess how I'm gonna find out. Source: hopium

      It's more so I'm using the 1x piece line from HEL that goes from the body to the caliper. There's no middle block/mount like the HFM ones or the GKtech ones. There are certain angles/suspension compression where the line actually slightly contacts the ARB. Below of how mine sit (not my photo): How I want it:
