Rx7 injectors arent very good for use in cylinder motors, the spray pattern is not very nice and most of the time you'll struggle to get a decent idle. They are a decent size for cheap but your better off spending that little bit more for some proper injectors.

I bought a set for my motor originally back in the day, and we had to go through 8 or 9 injectors before we found 4 that flowed the same and werent f**ked

rx7 injecters are good, compared to high flows atleast..

since runnin them my cars idle is allot smoother goes through less petrol and starts easier and actually drives better when cold, car still pumped out an easy 400hp ...

but yea spray pattern not so good, still better than high flows

yep!

375cc hose tail @ 3 bar.

RX7 are O'ring and 550cc @ 3 bar.

I'm using 380cc hose tail @ 3 bar in my L28et rebuild and 780cc Rochester Delphi (14mm O'ring) in the FJ20et, or maybe 770cc Siemens Deka. Doesn't matter as I have both plus 570cc if I choose to use premium 98/100 octane petrol.

Cheers, D

    • Hey, it's a GT-R, it's just as significant a moment as mine😁 It's not ideal when things are uncertain; I'm the type of person that always has a set plan for things in life so being unsure of this plan puts me in a weird place mentally.
    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card style AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had no flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.
