turbocad's custom fx

Whats up, I'm a forum lurker here and I cant believe I have never seen this thread before. I totally just killed two hours on these 35 pages!

Great work, keep it coming with pics and updates!
 
hey guys, thanks for the props... wow, 35 pages :smile:

Turbo I would love to know what should I do to put in a big screen in 2006 FX35 with Navigation since my FX does not have Navi. Can you guide me in the right direction, like where could I buy the parts, etc. Any advice you be greatly appreciated.


Thanks,
Jose

a big screen? be harder even to do in 06+ & look factory cause the controls are larger, you've got no room to take much away to make extra space. I had the extra room from removing the tapedeck & it's covering door. you would need to do more custom work than I did & that was not easy really, would be a ton of work on the 06. best advice would be get a spare control panel & see if you can disect it & remote some of the controls away from the center & remote mount.def can be done but def pretty hard to do. another variation may be to completely move all the controls complete down into the console, that would be the easiest practical way to do it I think. then you've got enough room for up to a 15", or a 12.1... whatever. the posibilities are all there...


ok, guess I should update this thread :smile:

I know a lot of guys look at my fx & think that it's radical or that it's all that, but to me I don't think that I've done anything so radical to the fx yet. the screen/pc install is probably the most impressive & intense thing that I've done to the fx so far, but even that is not so radical, maybe a little:shy:. most other things are just kinda tinkering & while being modifications I don't think of them as extreme or very radical really. in my eyes so far all of the mods I've done are nice, but kinda tame & mild. wheels, suspension, brakes, lights, mirrors, grilles are all pretty mild things. agreed that all togeather it does make it unique & individual & a give her a personality that I think is hot, one of a kind I guess, but not so radical yet.

haven't really done anything so radical in the 2 years I've had her because I just never wanted to have any time that I could not drive her. I didn't & wouldn't want the down time. I really don't want to have to drive anything else even for a day :frown: I could only do mods that were built seperate from & off of the fx & then bolted on the fx, never negatively affecting the fx in the process. modular but basic mods.



last year I bought an engine/tranny complete divetrain from a wrecked 07g35x awd. I originally thought to start my engine swap this winter, but winded up just continuing to drive her through the winter even on & off. even got caught in a few snowstorms, on the summer tires & 22's... was not good... winded up killing one of the wheel lips in a monster pothole from the freezing weather... that was the final straw, I wasn't really ready to do the swap, still need parts still need to clean & paint the drivetrain, still need to figure out the wiring but I decided to just put her in the shop & start, it will never get done if I don't start, so the shop bay that she sat in when she was still in silver & in pieces while getting the custom paintjob when I first got her is where she sits again


now I have finally started on a mod that is a bit more radical than anything I've done to the fx so far. I pulled the drivetrain & harnesses out of the fx in prep for a motor swap to the VQ35HR motor. same motor as the 09 fx35's too. twin throttle bodies & 7,500rpm redline, much more stout motor that can handle some good power well beyond the original VQ35DE. this is a little radical because of all of the differences in computer controls & because of all of the complications of the can buss controls & all the custom work it will take. I want to retain traction control & the vehicle dynamic control (vdc) system too, as well as intelligent cruise & everything if I can

to complicate this swap a bit more, I'm also building my own twin turbo setup for this drivetrain swap. I'm building my own turbo mount headers, all pipework, custom made intercoolers & pretty much everything else from scratch rather than buying a pre made kit. I've looked at all the twin turbo kits out there but none of them have really been what I would consider awesome for the fx. all of the existing twin turbo setups are built for 350Z's & are designed around the limitations of a 350Z fitments. the jwwtt & gtm's kit, even the greedy kit just didn't do it for me. the FX has so much different space to work with & I really want to take advantage of that & build an install that just sits right with me, built specifically for the fx. if it's not available then the only choice is to build it yourself, so that's the plan


I stripped everything completely out, I'll finally get rid of the remaining silver :tongue:

thes are the 2 harnesses, one 03 fx de & one 07 g hr

engine side
1



dashboard side
1



this is the point where it transitions from engine to dashboard, the hr motor has way more wires than the de had. each wire has to go some place too, & only the right place will do. the wrong place can cause expensive damage... this is the real work to this swap & part of why it is more radical, sticking the engine in & out is easy by comparison, finding the right place to stick each & every wire & merging these 2 harnesses & having everything working perfect like it came that way is a bit challenging to say the least :smile:

this is the beginning of sorting the wiring stuff out. open up the harnesses & start to figure out what's what

1



these are the wiring diagrams... top one is fx de, bottom one is hr motor. def a bit different
1



& this is the ecu plugs... first problem, the fx uses 2 ecu plugs & the HR motor uses 3 ecu plugs, but only one of the plugs for the old & 2 of the plugs of the new engine are part of the actual engine harness', each ecu though has another plug for the ecu that comes from the dashboard harness... ahhh, I don't have the dashboard harness for the HR motor, but I really would still like to try to run this on the HR ecu... think it would be more correct & a more complete & proper swap, although if I have to I could & will fall back on trying to run it on the DE ecu with the help of a haltech, but I wanna at least try for the HR ecu first....

1



I found a guy with another wrecked g35x in a salvage yard a few states away, negotiating a few more parts. a few plugs & computers from him would help me do the HR ecu complete I think


I decided on black for the motor & I'm going for a black industrial look under the hood I guess, no patience to sit there & polish it all up to show finish, no desire to show it but want to drive it every day & nyc weather is just not show polish friendly at all so all black it is, only things under the hood that are not black will be just a few polished aluminum or stainless steel details, so black & chrome look with mostly black I think...

haha john, what did I tell you? I'm a distraction! the week I go back to school you finally get some of your own project done LMAO

but yeah, it looks great man! loving the stealthy all-black look...
 
damn this is crazy im feelin ur fx

is that a tablet pc in ur dash howd uu get the kit ?
 
What a kick in the ass. The wires alone would give me nightmares....The engine looks mean, with the bay all painted up nice and slick - perfect.
 
the harnesses already are & def will cause me many more nightmares before I'm out of the woods there :tongue: I'm into this wiring pretty deep now & honestly it's much worse than even I originally imagined, no wonder Nissan techs have even said forget it, not very doable:frown: I stare at all the diagrams & realize that even the complete diagrams don't show every wire in the plugs because they must also be from other different subsections too. also Nissan's fsm is not really deep enough into the actual circuit & harness layouts, so there is just a lot of information that is just not there & the info that is there is broken up & spread out through different subsections.. the fsm's are more designed to help a tech diagnose & repair an existing car with an existing problem, NOT to help with something like this. I'm already finding wires in plugs that the manual shows no wire there & color code inconsistencies too

another bigger problem is, even though the 07 is not documented well enough for something like this, the 03 fsm is even worse. it's almost like they just skim the surface where I really need more detail. I need to print out multiple parts of partial diagrams & charts & then figure out the missing pieces... then refer to other charts that list the plugs but not what the circuits are, no color coding even listed in the actual wiring diagrams... I sit there & stare at both manuals back & forth for hours taking notes & marking up my own notes for any intel I gain & I'm telling you, after a while I think that you can actually see the smoke pouring out of my ears :laugh:

this is def one of the biggest wiring challenges I've ever faced. I've done plenty of complete car rewiring & harness grafting before, but nothing quite this intense & technical.... but, in the end it still boils down to one wire at a time, then move onto the next... whatever I can't find out in the diagrams I will have to find out by physically tracing the wire to it's origin... this is a lot of fun & this is def do or die. my fx is useless until I get this all figured out & working again so failure is just not an option.

I now have a guy sending me a bunch of plugs & wiring chopped out of another g35 from the dash... another ecu from an intelligent cruise car, also the bcm & the security module, even the later model Ikey... I may also switch out to the new key & push button start from the g, I'm already in there & rewiring everything, so this may be doable at this time too.... a lot of fun :cool:
 
much props and this is what I would call extreme. I am electrician and sometimes that what needs to be done trace each wire label one at a time. good luck bro.
 
the last big wiring conversion I did similar to this was in my turbo cadillac. the car body & body harnesses is a 1983, originally had a 4100 v8 engine in it. I swapped out to an 87 grand national 3.8SFI intercooled turbo drivetrain. I also swapped to the 91 fleetwood brougham digital dashboard., complete with the 91 electronic climate controls & a lot of other updated 91 controls, so there were 3 different cars grafted into one electrically. at first when I put it togeather I just cut wires I didn't need from the old & added the wiring I needed for the new to just get everything working, which I did, drove it & raced it that way for a long while, but there were tons & tons of extra unused & cut wires buried in the dash & it was a mess. even though everything worked fine & was mainly buried it still annoyed the hell out of me


so one year when I first got my shop I closed the shop for a week between christmas & new year, & I spent the whole week every day from very early to very late working on completely rewiring that car with the whole dash out of the car on a bench & the car in the middle of the shop. by the time I was finished the whole car hanesses was neat & there was not one wire in the whole dash that was dead, not one wire out of place, not one connection that was not soldered . I wired the whole thing with bulkhead plugs so I could disconnect & completely remove & reinstall the dash at any time in like 15 minutes, everything just unplugged thru 3 bilkhead connectors. that was a major project. this one reminds me of that, I don't really know yet that this conversion I'm doing now is really worse than that one was, it was pretty intense. this one may wind up being easier than that one really, I hope

now with my fx I winded up getting very lucky I think, I winded up getting most everything extra I need for a complete swap from a fully loaded g35x with tech package. my motor originally came with an ecu without tech so that would have been a communications problem.from the tech car I now got the ecu, the extra dash harness plug for the ecu that I was missing, I also was able to get the body control module with all the plugs, the imobilizer module which is also a transponder reader, (the key can be docked in it if the key battery dies) this system doesn't use a key cylinder at all because it is all a push button ign system. I now have about everything I need to have my fx function & run just like it's an 07 g35x.

that is my goal now & what I'm going to attempt first, to get everything rewired to the point that the whole electrical system is upgraded completely including the pushbutton ignition system & all. I'm [ST]expecting[/ST], ok, hoping :tongue: to be able to pre-wire everything, plug everthing in, hit the start button & have my engine start up & run, no check engine lights & everything functioning just like it was actually still in the g35x & as it came from nissan, haltech not even in the picture yet. yeah, good luck with that :wub: I really think I can do it now with everything I have now :smile:


as delivered, chopped right out of the dash harnesses

all additional dash harness & bcm wiring exposed for tracing, I did not get the 12 pin connector for the imobilizer module though, gonna probably just have to make that one myself i think

FROM TIME TO TIME WE ALL MEET PEOPLE THIS GIFTED . BUT TURBOCAD IS A FX-GOD . VERY NICE GUY .I WENT TO HIS SHOP AND LOOKED SOME OF THE CARS HES PAINTED THE MAN IS A GEM! KEEP UP THE GOOD WORK US CAR GUYS NEED YOU:tup:
 
wow, is all i can say. I see you even got the ikey charge unit in the pics!!

are you planning to also swab out the 1st gen cluster with the newer cluster? that would be a sick addition, and knowing you, fabrication would not be much of a hurdle
