Hello there! while driving my stereo system turned off and wouldn't turn back on. The next day I drove around then all of a sudden my car would choke/stutter in 2nd gear, I drove home slowly and took 3rd and 4th gear a bit higher with no issues then dropped into 2nd and started to choke again at around 4k revs.

Got home took battery terminals off then back on. Stereo system works now butchoking remains. Gave it a rev in neutral and same choke at 4k revs.

Any ideas?

Mods are as follows: nismo front mount, autronic ecu, injectors, spitfire coilpacks, n1 turbos, tomei fuel regulator with walbro in tank pump, 3" turbo back exhaust, turbo smart bov, boost controller 2stage, blitz turbo timer. Has previously had a dyno tune.

Any help is very much appreciated !! Thanks guys

what do you mean by choke? do you mean misfire? if it is just misfiring then how old are your plugs? if they are old then that may be the cause, but it may also be that you have a failing ignitor or coilpack or even an issue with one of your afms

It ended up being the limiter. Very strange that it would just change while I'm driving. I thought it'd be in limp mode but not sure thats possible cause the ecu is aftermarket. Any thoughts on how this could happen? I'm thinking there could have been some kind of shortage or something

      Have you done your thinking backwards? 3 bar, 43.5 psi pressure drop being the presumed specification for an injector, means you need 3 bar upstream when they are firing into atmospheric pressure, and more upstream pressure than that when on boost (you add your boost to your rail pressure to maintain 3 bar across the injector) and you need..... less pressure upstream when you have vacuum in the manifold. So, presuming that you're idling at -10 psi, then you only need ~23 psi in the rail. I realise that I did not need to say all of that to you specifically Matt, once you'd realised your mistake. It's mostly there for complete clarity for others.

      Have you reached out to the guys at Spool Imports? They are a Ross dealer, I can imagine they would have the rings just sitting on the shelf (I could be wrong).

      There's one for sale at Grand Auto Wreckers in Lonsdale (SA), for .... let's suggest the sum they're asking for will make you cry. You may have to embrace the idea of modifying the rear subframe to accept some other diff. You could probably find a way to wangle a shortnose into there, with a custom rear adapter and some sort of shenanigans to relocate the front mounts. This has probably already been done by others, so there might be some guidance available as to how easy/impossible it is, out there in the googles. But you possibly needn't restrict yourself to Nissan diffs if you're going to contemplate that. There are similarish Toyota diffs, possibly some Euro ones, possibly some Seppo ones.

      The ball joint taper and arm taper have to match angle and diameter, but just doing the bushes is a much better option.....seems like the industry moved to "it is cheaper to replace the whole arm than take on the labour for changing this bushes", glad the aftermarket supports it

      Gee she looks a bit rear heavy in that first pic! Sounds like a great project with the kids, but as I guess you know R series stuff is getting hard to find and pre that is pretty much impossible these days
