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:

      Questions on potential new purchase

      By latino_R35 · Posted

      Hey all, not sure how active SAU is anymore but will ask away anyways. Just wanted to get some experience on the 2008 model GTR CBA model.  I've hit that age in my life (43) where I'm like fk it time to get my dream (midlife crisis) car. Looking at importing one in and seeing if these can be reliable if the main flaws are fixed up. Plan is to keep money aside to do the following straight off the bat to future proof it: * install a stage 1 rebuilt trans with all new bits and pieces.  * install a new Bellhousing from the later model GTRs. Or potentially an upgraded stronger version like MAD or ATR. Besides the above two things and typical maintenance items anything else you'd recommend doing.   Been speaking to a few people and the engine on these are very reliable apparently. But keen on the view of the community here. Hoping to find a nice grade 4.5 with low mileage in Grey. I'd go black but swirls too easy. Look forward to your responses and feedback. Cheers

      Do Alan and Keith work on Skylines now? I remember buying stuff from them when I owned my Ralliart Lancer a few moons ago. Definitely genuine guys and be excellent if they dealt with the skyline platform as well.

      Hey all, I'm Gaston from Sydney's West.  I was a member on here when I was a younger lad and owned a mint R33 GTS-T. Ended up selling it and getting married having kids (yadda yadda) we all know how the story goes. Now I'm back with the intention to get my midlife crisis (dream) car ... a R35 GTR.  You'll see me about asking questions and searching the forums. Good to be back and can't wait to get back an Import again.
