Hi all , I'm keen on a Vipec V44 for the daily but they are set up for saturated or high impedance injectors . The daily needs to run the old hose tail injectors but there doesn't seem to be much going in this type that are high impedance .

From what I read Vipec do a peak and hold injector driver box for the V44 but if obtainable the high impedance squirters would be easier .

The engine uses 225cc high imp injectors and I reckon something in the 370-460cc range should do the job , I gather the V44 is more than up to the task of running injectors of this size in an 1800cc turbo four .

Some sites claim that some of the NA RX7's used a high imp 460cc injector .

Also I've seen mention of people using dropping resistors when converting from high to low imp injectors , I believe it is workable but you don't get the advantage of a peak and hold system without peak and hold injector drivers in the computer .

Any help appreciated , cheers A .

They are both low impedance injectors like most turbo ones of the era . The only thing that may be suitable are the RX7 460cc high impedance ones - series 4 I think .

It's looking like the peak and hold injector driver box that ViPec can supply is the cheapest option , it opens up a wide range of low impedance squirters so easier to tailor the injectors to the application .

Cheers A .

    • lol the 2nd one boss, thank you for pointing this out. I feel as i spend more time here this intro message is some thing i will always make me laugh and shake my head at. Perfect Intro:  I have the vehicle  
    • R34DE as in R34 with an RB25DE? So did you get this? Or you planning to?  I'm not really sure what you're saying. 
    • Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.
    • Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.
    • Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?
