Right, im currently relocating my battery to my boot on my R32 Gtst, from factory ( or how i bought the car) off the postive post on the battery it had the main starter cable running to the starter motor, postive wire running to the fuse box (this then splits into several, will post picture) and the positive feed for the fuel pump (brown wire with eyelet also seen in photo). My question is, can i run the positive feed from my battery using 0 gauge wire directly the the post on my starter motor, then run a positive feed from the starter to wires coming out of my fuse box? i will also wire the fuel pump directly to the battery in the boot. Also i will earth the wires that were on the negative on the battery in the engine bay. Will this work fine with no issues? or do i need to use a junction box of some description to run my main power feed to then run postive feeds off there. I hope this makes some sence.

thanks, Brad

Assuming it doesn't need to split off anywhere, that should be fine. I've seen plenty of engines hooked up that way. If in doubt though, you can get a insulated block and mount it in the bay somewhere, run the pos to that and 2 more to fuse and starter.

Oh and I didn't mention (but remembering now), Your really should put a fuse in line to the feed to Jblock/starter. And make it big. Like ~200A. If you are going to have a few metres of battery wire running in your vehicle, you are most certainly going to need to protect it. If that shorts your car will go up in flames.

this is what i did in my R34 my battery was in the engine bay and all i did was run 0ga upto the original battery location and then connected all the wires that went onto the battery post to the fusable link end and i also have another fuse at the battery end about 100mm from the battery. so at the battery i have a 200A fuse and in the engine bay i have a 150A so that if the engine or accessories blow the fuse it will kill the 150A fuse but if the main 0ga wire shorts out somewhere along the body theres a 200A that it will kill

No the fusable link is generally in the fuse box so normally off the battery to starter motor run theres no fuse. That black thing next to the oil filter is my fuse i do alot of car audio and its just a fuse that you can get from JB HiFi autobarn who ever mine is a pole type

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
