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 .

    • What can't be done with a little bit of decking board or similar timber bolted to a hub flange via 2 wheel nuts is not worth talking about.
    • I noticed something. On the tps sensor and the sensor behind the adjustment screw is adjusted towards the far left. Are these screws supposed to be centered? (this sensor was in the same position before the tune as well)  Also attached a photo of where my car usually idles at when warm (sometimes a tiny bit above that). I think I might have screwed up the calculation and it might have better than I thought lol at 750rpm still not 650rpm though.      
    • So for both general interest of engine health, and to rule out any coolant/oil issues, I organised an oil analysis done on the 125,000klm oil Results below, all good, just a bit of fuel dilution which I'm not too worried about
    • This is actually a really good way of measuring what wheels fit. If only there was a similar measurement between hub face and suspension :p That said, it's probably pretty simple to actually measure it all with the wheel off the car for the rear. The front is a bit more complex but.. 
    • Being the top Google search result for R34 wheel-related inquiries, lemme throw down my experience. I calculated that 100mm from hub face to wheel face is about the perfect fitment for my ENR34 sedan.  I've been running 18x8.5s, ET35, with a 1" spacer. So, 8.5in to mm = 216mm. 216/2 = 108mm. 108-35 = 73mm. 73+ 25 (1" to mm) = 98mm.  If you wanna get close to this on dif widths, here are the offsets you'll want: 9" - ET around 15mm 9.5" - ET around 20mm 10" - you're crazy, but ET around 30mm All these should fit perfectly on a non-widebody, non-GTR Skyline. Note that it's probably the absolute max, and you're probably better off running a couple degrees of camber in this config, but it looks great, super flush.
