No adaptor plug? You want the stealth look?

The Xspurt 2000's are bosch plug, possibly more have it, I would have to ask the wholesaler. You will require step down adapters to 11mm, or for the injector to be machined down to 11mm which I can have done for a little extra.

You would have to ditch the injector resistor pack for any modern high impedance top feed, just remember the 26 injector is a 30 year old design so anything based on that (ie same body design like Sard) will be crap. Newer won't have 2 holes either, possibly 4,6 or only one, but that makes fark all difference at the high gas speeds inside the runners.

hey scotty, thanks for the reply in regards to adaptor plug i don't want to use one just a straight drop in original plug design is what i'm after two holes or more obviously i would prefer i have used sard in the past and have found them easy to use and install never had a problem so i was hoping to find something of that calibre i know the amount of holes won't make much difference at high gas speeds but they do make a difference at lower gas speeds. If you don't mind me asking what is wrong with the design from sard just out of curiosity?

you dont ship to the US >_< best price i seen for 2000cc , also need adapters for stock rail.

I will ship anywhere, the website just ins't setup well atm due to not having any time to load all the data, and international shipping calculator add-ons are very hit and miss. PM me if you like. Our crap dollar would help you with pricing nicely.

Personally I wouldn't spit on Sards, I had a set here we pretty much gave away. Modern Bosch injectors crap all over them for economy and spray pattern, and any tuner will tell you it saves plenty of time on the dyno.

Anything bigger than Nismo will be a drilled injector which will likely fail on you at the worst time.

So much this. Having gone from Sard 800's to a modern 2000, I can tell you the 2000 idles much nicer and drives so much better than those old wrecks. To say "nope, nothing that doesn't drop in" for a sake of a plug change is crazy.

wow you wouldn't spit on them?

big call they're basically a nismo 600 with a larger orifice?

take like 7minutes to fit and no cutting factory harness yes there old as design but so is my car so there era correct :) and never had a problem tuning them but i would prefer at least 2hole design and only 100 each delivered.

good value I reckon

There is no cutting of the factory harness with the 2000's either, many modern injectors still use the same Bosch plug, and the ones that run US plugs have a simple adapter these days.

      Could you modify this duct so instead it pushes the extra air through the radiator too and not down and out? For temps, I know it's not the greatest idea, but as a bit of a last resort, you could use a very intermittent misting spray onto the front of the coolers/rad. You don't want to be soaking them such that water is dripping off, but a small most on/off so that the water evaporates. That point of it constantly evaporating, rather than being soaked in water, will pull a LOT of heat out of the cooler. I'm literally thinking just the little mist sprayers for a garden from Bunnings. Being in a low humidity climate it will help even more! The other trick if you want to be ghetto is some shade cloth hung in the opening, and keep it wet. Pretty much now it's acting like an evap cooler on a house, but cooling the air you need to use to cool the radiator...   On a topic to think about too though, when air enters through the bumper, is it all nicely ducted from the edges of that opening back at a nice angle, or is it like most cars, and the edge of the opening just stops, and suddenly it's wayyy wider behind that? If it does the later, get it shrouded out at nice angles. When that opening changes too rapidly, it can actually cause a high pressure zone between the front bar and radiator, and limit air flow into that area, which means less air for cooling, as it effectively stalls the air, AND adds to drag...

      It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.
