Caboobaroo Posted May 30, 2013 Share Posted May 30, 2013 Ok I need to make one thing perfectly clear guys. Because GM had partial ownership of FHI back in '05 for a few years, starting in 2006, Subaru started using a CANBUS wiring system instead of the traditional system they had been using before. So unless you want to run an aftermarket management system, you will want to find a '01-'04 non AVCS 3.0. In '05, they started using AVCS and then '06, the wiring changed completely. They also started the DBW system in 2005 as well. I've been contemating running a 3.6 in my RX with a MegaSquirt 3 to control it. Link to comment Share on other sites More sharing options...
matt167 Posted May 30, 2013 Share Posted May 30, 2013 Matt, Thanks, I do understand. My point was IF I have to use everything from the Subaru to make it work and the computer to operate; I'm not sure if I will be able to use all the wiring, computer and ABS brake system from the Subaru and (somehow) be able to connect the ABS wire connectors from the Subaru harness to the Hubs/Bearings of a 2004 and up Impala with ABS? Or the other choice - IF it do NOT have to use the ABS and wiring for it from the Subaru - I could use everything from the larger Impala. Either way the outer CV joint on the Subaru axle would have to be replaced with one that fits the Impala hub. Or a custom axle made with the correct ends for both. Tony ABS wheel speed sensors are just voltage generators. You most likely can swap the connectors for the correct ones and the system probably won't care.

USMB Drunk, The only reason I'm even talking about GM - is because I have another Ultravan project - using a FWD GM 3.8lt Supercharegd power plant and the 2004 up Impala front hubs, bearings and disk brakes. Because I already knwo that those bearing will handle the finished weight of these Ultravans - i like to use the same setup on the Subaru. The thing we were not sure of is do I use the entire ABS from the Impala? And IF I do - would it mess up the computer part of the Subaru? So I be better off trying to see if I can keep all the Subaru stuff and only use the hud, bearings and brakes from the Impala? (Sorry this might be all messed up! ggg I just got back in form cutting grass in the hot sun for hours.) I thought as long as I had a complete donor Subaru to remove everything from the same vehicle, that I would be able to do an newer conversion. That way I'm trying to mish-mash parts from different year and models. Tony Edited May 30, 2013 by Ultravan Owners Link to comment Share on other sites More sharing options...
Caboobaroo Posted May 31, 2013 Share Posted May 31, 2013 I'm saying that because the wiring on the 2006 and newer 3.0s and 2007 and newer 2.5s use a different wiring configuration that does not play nice in swaps. Only way to overcome all of the issues it will have is to run a stand alone fuel and ignition system, such as a MegaSquirt (MS3X), Link or the few others that can support the AVCS systems. As far as the mechanical aspect of it, convert away my friend! It's definetly an awesome project that you're diving into. Link to comment Share on other sites More sharing options...
Ultravan Owners Posted June 4, 2013 Author Share Posted June 4, 2013 (edited) I don't see how throttle by wire would be a bad thing in this. Much better than a 10 foot long custom accelerator pedal. The signal wiring from the pedal to the ECU may be shielded. I'd have to dig up a service manual to find out. That wouldn't stop me from just extending the wires to the pedal assembly though. Obviously there are quite a few more that will need to be lengthened if you plan to use the whole interior/dash anyway, what difference do a few extra wires to the pedal box make? Bump and a Reminder... Were you able to find anything about the drive-by-wire for the throttle? Also how is it shielded? (I've never seen a system like htis before.) Thanks, Tony Edited June 4, 2013 by Ultravan Owners Link to comment Share on other sites More sharing options...
WoodsWagon Posted June 5, 2013 Share Posted June 5, 2013 Use the matching AWD transmission and remove the rear transfer section. You can't flip the diff in the a/t because they use hypoid gears with and offset pinion centerline. However, there was someone who used the gears from a 4eat and cut and welded the pinion to a 5mt shaft to use them in a 5mt, so you could potentially do the opposite using the the reversed ring and pinion set offered by http://www.subarugears.com/ for the 5mt and modify them to fit in the 4eat. It would suck to cut up $2k worth of brand new gears and have the experiment fail though. The other option is VW hub reduction boxes. They reverse the direction of the axles and give you extra gear reduction. They were found up to the mid 60's in busses. Link to comment Share on other sites More sharing options...
