    Ford Super 8.8 irs swap thread. Rear brakes too

    That is something that I was wondering as well, although I was looking into how to adapt the datsun hub assy to accept a cv spline shaft. That may be better for some of our applications, but this build seems more universally useful. What did you use to attached the bottom of the knuckle to the control arm? Is it just a threaded rod or is there more to it that isnt visible?

    What material are you fabricating it from? What are you looking at for the welding process?

    Oh, i didnt see where you posted that. I will likely build my own mount specific to my setup but im still interested in your process and how you are designing your custom knuckle.

    Ford Super 8.8 irs swap thread. Rear brakes too

    You said in your initial post that this setup could use the 2002 and up explorer 8.8 by simply using 31 splines instead of 34 on the end of the CV joint. Would it also work for older 8.8s out of explorers? I have an 01 out of a mountaineer that I believe is identical to the 02 explorer 8.8; 3.73 gear, LSD, 31 spline, disc brakes.

    Have you looked into having the axles cut and then welded rather than resplined? If they need to be shortened, it may be possible for a high tech welding shop to simply weld the two halves back together. Although, if it only costs 75$ ea to have them cut and splined then high tech welding may not make sense. Do you know if the shop that is cutting the splines is going to induction heat treat the splines as well? Not sure if this applies to all axle shafts but I have read that it is common for only the splines to be induction hardened.

    Drivetrain swap talk

    Last I had read, the 8.8 swap is almost just as much work as an R200 short nose, or maybe doing an IRS 8.8 is just as much work? I have a perfect 8.8 for the swap, 3.73 geared, limited slip with discs. I don't really care about keeping the IRS, so if it is in fact easier and cheaper to swap in the 8.8, then I can definitely use that.

    Drivetrain swap talk

    Oh, geez didn't notice that, thanks. I have done a bit of research on the rear differentials. G35s have quite a bit more power than a 5.0 puts out stock, rated for over 260hp and ft/lbs stock. The 5spd MTs and ATs seem to have an open differential unless they have the tire and wheel package. However, the Open differential has an electronic system that seems to brake the slipping wheel enough to allow you to burn both tires. The 6MT cars have V-LSD differentials that seem to be very stout, although I have read that hard tracking will heat up the viscous fluid and reduce it's effectiveness temporarily. There are quaife and OBX upgrades for these differentials. I believe these are the same differentials use in 350z and 370z cars which may explain the decent aftermarket following. Looking up the VLSDs on ebay, I was able to find a few for around 200$.

    Drivetrain swap talk

    Hey guys, with a lot of new cars out on the market, I was wondering if anyone has looked into new potential rear differential swaps. I have seen a number of Infiniti G35s come up for sale for parts for very low prices. These are 3.5L V6 that come in either RWD or AWD. The rear differentials seem to be fairly priced. Curious if anything has looked into modifying one of these to fit our S30 chassis vehicles. I am working on a 5.0 swap into my 77 280z that will require a much beefier rear end than my R180 open diff. Starting power goal will be around 250hp and 300ft/lbs at the wheels.

    280z 302 sbf swap

    Ah bummer. Has anyone ever looked into the rear differentials in Mazda's RX-8? They are helical torsen design and supposed to be fairly tough.

    280z 302 sbf swap

    I also read that Nissan Armada SUVs use an R230 as their front differential. Might be able to find one of those in a junkyard. What differential do post 2000 maximas use?

    280z 302 sbf swap

    Yeah the 1st gen EFI system in the mustangs were very unreliable. The only other big piece of this puzzle is the rearend, I still havent sourced one. I was looking at trying to find an r230 but they seem to be just as difficult to find as an LSD r200. I did find that Mercedes benz used r230 rears in a number of mid 2000s sedans, but i believe they are geared pretty low, around 2.75 or something. Not sure if that would be very good in my setup but they are filthy cheap on ebay.

    280z 302 sbf swap

    Hey! Yeah ive been spending a lot of time over on Corral forums figuring out the 5.0. I pulled the engine and the entire electrical system out of the mountaineer without damaging it. Something I didn't realize was that this is the post-modular EFI system which does not use a distributor. Supposed to be a much more robust and efficient system with much better tuning options but the options aren't as well documented as the older EFI systems. Engine is currently sitting on my crane, waiting for bolts to mount it to my stand. I just dragged the mountaineer out of my shop. I am looking at two options for the EFI system. I can either use the factory EFI system and buy a quarterhorse or F75 chip from Moates. That will allow me to tune and control the Factory ECU. This is required for a number of reasons; The ECU will be in limp mode because I wont have the AT which also means I wont have the VSS signal that was from the AT. Also - The passive anti theft system will need to be deactivated. The quarterhorse setup will run me about 500$ for the hardware and software. Alternatively, I could use the Megasquirt 2 DIY kit which is ~350-450$ with the harness and software. This is fully programmable and bypasses the security and what not.

    Thanks for the links there bud, bookmarked both of them. I was already assuming that I would need to have a driveshaft made. The mustache bar wont be an issue as I have all the tools needed to fabricate them. I have the prints from the Laine web page on my computer.

    My 77 280z was a 3 spd auto, I believe it has an R180, 3.54 open. I dont think any R200 will be a direct bolt in

    What are the ideal R200 donors? 300zx? 240sx? Are there any other vehicles (non-nissan) that are also potential donor swaps that I should be looking out for?
