Heyas

I see alot of gtrs here use sard 700cc injectors, has anyone ever had any problems? someone said they squirt too much in low revs so have trouble idling or something maybe, and also were they any trouble to fit to the fuel rail?

Im also going to upgrade to a bosch pump, im assuming the 044 is a replacement intank pump right? is there much hassle to swap one over, and also where is the cheapest place in aus to source one from, as all the overseas places dont stock them obviously..

Sorry for all the questions :slap:

I've heard nothing but good things about SARD, there injectors and regulators are top notch.

044 isn't a 'direct fit' into a GTR so to speak, but can be installed without much trouble.

Pm the user 'phat32' he helped me with getting bosch pumps

we are using sard on staceys race car and no probs.If using the standard fuel rail you will have to downsize the o-ring as the standard o-ring is too thick.The bosch pump should work just fine in the factory in tank position.We had one that was good for 350Awkw.

As long as the ECU is capable of controlling the injectors you won't have any problems, for example I have seen a Power FC running 1300 cc injectors no problems.. The 700cc injectors are good for ~700bhp so I assume you need that you need sort of fuel supply to support your target power output. I would always recommend that you get the closest sized injector to your power target, it makes tuning easier. Leave a bit of headroom of course.

We buy our 044's from the local Repco, a trade account helps with the prices. Do a search if you want to know how to fit an 044 into a GTR tank. If you are realy looking at 700 bhp I would suggest a surge tank using your standard GTR pump as a lift pump and feed the 044 of the surge tank.

Hope that helps:cheers:

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
