hey guys got my sard 280 installed a fw days ago, have been driving the car here and there and not running hwo it should or hwo it used to run, yous guys think it will need some kind of a retune or about 1hrs dyno time, the car also cut out for liek the 1st time today, i bought the pump and it seems to be in excellent condition but car isnt running how it was, maybe because its pumping more fuel and the injectors cant take it, yous guys htink it needs a retune because if it does its better to just upgrade the injectors and gett it retuned but i knwo thecar aint going nowhere as it still has the stock turbos and they are useless, what do yous guys think, upgrade the injectors because i dont have the cash for the turbos atm but in the next couple months can get a pair of gt2860r -5 or sumfin,

please guyas tell me what could be the problem or if the car just needs a retune and so if it does yous think upgrading the injectors would be a good idea?

cheers tony

Me either. If the old fuel pump was dying... then the new one should fix any problems...

Was the old pump even tested before being pulled out? If not, then you really cant say its got anything to do with the pump

Take it to a workshop.

what im trying to say is with my old pump it was running fine but after i got my new sard 280 pump installed it feels like it has lost a bit of power and running much more rich as i can easily smell the fuel, so now im guessing the car will probably need a hours dyno tune just to check the fuel mixtures but if it does need a retune i think its a good time to upgrade the injectors, right?

Well no-one will know, youve gotta check the AFR's. If the old tune was on a dying pump (which you really would hope wasnt the case, but sounds like it) then adding a new pump could make it super rich. Could even be a fuel reg dying and over fuel.

You really cant tell over the internet.

Injectors - Not if you have stock turbos??? Its wrong time.

Then you gotta tune it a 3rd time when you get the turbos, i fail to see the point in doing injectors now as there is no benefit what so ever if your only going to change it again and again. Wasted money on tunes

i put sard 720cc in mine the stock inj were 95% maxed out at 262rwkw on the stock r32 turbos on 13psi....

with the new pfc it was as easy as putting the new inj in loading up my old map and putting in to the lap top the new inj sard 720cc and it just loaded up my old map for the new 720cc inj

cost very little and no time at all to do!

but i would get some one to look at it first for your fuel pump problem..... im about to put my sard pump in and was told its just a straight bolt in and no need for a retune at all!!!

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
