  1. Love the 4AGE so much :) I must admit, I do miss the growl of the old carbies, but the new 4AGE does go very hard...especially with 4.77 diff ratio :P

     

    By all means if you have time, feel free to add this to the FAQ. My aim in the first place was to help other people here, so go nuts with it in the FAQ.

     

    I probably won't have time to do a better write up anytime soon (busy as with work etc), but if you have any other questions, feel free to ask!

  2. Okay, I know it has been a while since I updated this, but I have finally been able to drive the car and test it :)

     

    So far I have been driving around a week and have had no problems with it at all. This has only been timid driving at the moment so obviously no clutch kicks etc. With normal driving conditions it works perfectly and has had no issues so far!

     

    Okay, I know it has been a while since I updated this, but I have only recently bleed the clutch and been able to drive it.

     

     

    My only change (personal preference) will be to replace the standard pedal return spring with a slightly stronger one. The stock one works fine, but I'd prefer if the pedal felt a bit more firm/harder to press.

     

    Other than that, all is sweet :) Will report back in if something goes wrong, or when I start abusing it a bit more!

  3. Well, after some very f@$king awkward measuring, I worked out the position of where the bracket had to be welded to the pedal.

     

    Tacked it on and tested it...

     

    ...Couldn't believe it, it actually was in the correct spot! :D

     

    Didn't worry about bracing the 'L' Bracket as I ended up rotating it 90º so that the weld runs inline with the travel of the pedal, as opposed to how I had it drawn with it being perpendicular to the pedal. Obviously time will tell, but it seems like it will hold fine.

     

    So yeah, measurements are below for anyone who wants to try it. These were taken with the clutch pedal in the 'disengaged' position. (ie. If you had no foot on the pedal)

    And how it looks from a few angles:

    Obviously I can't test this 100% at the moment as I don't have the T50 in yet, but I have full travel of the clutch pedal and the MC pushrod has the same travel as it did when it was in the sprinter, so theoretically it should work...

     

    Will see how fire wall flex goes too. That was one thing that didn't even occur to me when I did it. I have never seen an AE71 pedal box before thus didn't know it braced the firewall. If flexing is an issue, it should be a piece of piss to make a bracket that goes from the firewall behind the booster to where the clutch MC mounts. Will see how it goes first :)

  4. Hey guys,

     

    Currently doing a 4AGE into my KE70 at the moment and I am up to the exciting part of converting to a hydraulic clutch setup!

     

    Now, I know the obvious route to take is to fit an AE71 pedal box, or a t-18 with minor mods, but I am deciding to modify the original KE70 box to use the clutch master cylinder I have here from my donor AE86 as I'd rather not pay the $150 + that most people want for the AE71 setup and also, from my first assessment, I should be able to make the KE70 pedal box work easily.

     

    Firstly, here is how I plan to do it:

     

    t7sk5mew1ecxi62lw5uqfr2l6y6uvwbcfibrqc05xdaf5uxn0r.jpg

     

    From what I have seen, with the clutch MC mounted in the factory position (mould in firewall), the pushrod comes through 'X' amount out of line from the clutch pedal and clears cabin parts, so it can move in and out with no obstruction from anything. See below:

    The measurement 'Y' is the range needed for the clutch to work. Pretty much fully extended (clutch disengaged) to fully depressed (clutch engaged). Now, by knowing the range of the master cylinder pushrod, I can work out the position of where it has to mount to the clutch pedal so that when the pedal is depressed, the travel of the master cylinder pushrod is correct. Common sense shows that by having it mounted closer to the line of the pivot point, the travel of the pushrod will be less, and obviously making it further from the pivot point will increase travel. Find the 'sweet spot' and pushrod travel should be the same ratio to the pedal travel.

     

    From here, all I need to do is just make an 'L' shaped new bracket that connects the clutch pedal to the line of the master cylinder and mount the pushrod into it so it travels the correct distance to engage the clutch. Obviously this bracket will be inline with the master cylinder in both axis so that the pushrod slides in straight.

     

    At the moment I am yet to make the new bracket for the pushrod to mount off, but I just wanted to post this up to see what everyone thinks of my current plan before I get too carried away :P Also open to any suggestions you may have!

     

    I will make sure to keep this updated as to let people know how it goes, and hopefully if it works according to plan, people may be able to copy it as an alternative to the AE71 Pedal box :)

  5. My KE70 had 330xxxkms on the original odometer. I then wanted to change to a tacho dash with 250xxxkms on it, so I just swapped the 2 odometers around so I still had the correct amount for the car. Honestly, no-one is going to know any different as both odometer are identical, bar the readings of coarse. You are doing the right thing by keeping the numbers correct, so to be honest I don't think you would have any problems at all. Only reason it would look bad would be if the car suddenly had 100xxxkms less all of a sudden...

  6. I'm gonna go with above^^

     

    The size of wheels you have, I'd be very much guessing that they are probably somewhere +10 to +20, which if reversed will make you have some stupid amount of negative offset.

     

    I don't know the correct mechanical way to word it, but think 'levers'. If you move the wheel further away from the hub (- offset), the forces from the weight of the car will be magnified thus causing stupid amounts of stress/wear on your bearings. Having the wheel sit closer (0 - + offset) will mean the forces are going to be more centred on the hub, thus no excessive wear on the bearings. Mightn't be 100% wording it, but in my head I can picture what I am trying to say :P

     

    Dave, the amount of times I have seen this question come up on forums, I really think you should put your mad engineering skills to use and definitely model something in Solidworks! Would sum everything up nice and fast, and be easily understandable :P

  7. Another update for anyone interested.

     

    Wheels arrived a few weeks back. Sand blast + Powder coat and they looked like this:

    Found another set on Yahoo Japan (14 x 7.5 -1) So when they arrive that will complete the full set :)

     

    Also bought a manual 4ac AE71 for $400 from a friend of a friend of a friend's associate a few months back. Plan with that being to do the 4agte conversion in it and then swap it all out into my blue car one weekend. As it sits at the moment:

    Spent earlier tonight doing the oil feed for the turbo better using a T piece so that I have the feed and oil pressure switch from the same point. Also remounted the radiator and tomorrow will be trying to do all the plumbing associated with it.

     

    Pending the weekends events, might also work out cooler mounting and consider starting the wiring of it...Not looking forward to that at all.
