    Toyota E153 transmission swap

    I've never done a worklog before because most everything on my car has been pretty much "by the book". Nothing super special, complicated, etc. This is something pretty new so i thought you guys might want to check out my progress.

    I'll probably just keep updating this first post with info as i go along.

    Right now I'm still in the parts collecting phase, and have been since winter. I'll post 100% details on all of these parts once I've confirmed that everything works properly!

    So far I have in my possesion:
    Toyota E153 FWD transmission
    Quaife LSD for above transmission
    Shifter assembly, cables
    2 pairs of axles
    Intermediate shaft and drivers side axle stub (these axles use bolt-together inner CV joints)
    Clutch pressure plate

    Things I've figured out, but do not have yet:
    Clutch disc
    Clutch TOB
    Trans adapter plate (should be finished soon!)
    Upper trans mount (being made by the same guy who's doing the plate)
    Gaskets/seals etc. for the trans

    Things I need to figure out/have made once I get everything above:
    Front/rear lower mounts and brackets
    Custom subframe to bolt the mounts to
    Adapter bracket to bolt Toyota intermediate shaft to the BP block
    Clutch hydraulic lines, and master/slave volume ratios for correct clutch action
    May need to re-do my IC piping to clear the trans

    Here are all the pics i have so far:
    overlay of a BP bellhousing pattern with the toyota pattern, and a poorly made adapter plate behind both in orange. the plate is being redesigned to not suck

    random picture of intermediate shaft and bracket

    stock MR2 LSD vs. stock escort diff. i sold this LSD and bought a quaife instead. note the sheer difference in size, the MR2 diff weighs 30 pounds!

    my new front axles vs. a (broken) stock escort axle

    my E153 transmission


    shifter assembly, shifter cables


    bellhousing pattern, with some notes regarding how far off the original adapter plate is

    time to let the cat out of the bag and get all of this info together in one place

    the stuff you need to pull this off in a FWD BP powered BG:

    OE parts needed:
    celica alltrac ST165/185/205 shifter and cables.
    some are longer than others, beware. ST165 cables are BARELY long enough, that's what i have. the camry stuff will work but the shifter base is huge.
    2000ish Camry/Solara v6 5 speed trans
    LSD of your choice, buy for 93-95 MR2 turbo
    new bolts, bearings, speedo gear, snap ring for LSD
    (note, the camry open diff ring gear bolts are TOO SHORT
    also note, these transmissions are much more difficult to take apart than the good old G series.
    )
    91-92 MR2 intermediate shaft/bracket
    91-92 MR2 drivers side inner axle stub
    (note: these are generally inexpensive and work for the all the aftermarket LSD's. If you want to use the stock viscous LSD from a 93-95 MR2 you will need the two parts above from the 93-95. these will fetch inflated prices.)
    Celica Alltrac ST185 front axles (hybrid with MR2 inner axles above)
    91-92 MR2 cable drive speedo sender
    90-94 protege LX speedo cable (fits toyota sender, will also connect to escort speedo)
    ('88 RX7 balljoints w/ late style BG spindles) -or- (MX3 LCA's) to widen track slightly

    Custom purchased parts needed:

    custom clutch disc, 8 7/8" OD with 21 spline toyota center hub.
    adapter plate (dur)
    bushings for mounts - i used Energy suspension #9.9483

    Custom machine work and "machine work":
    machine off weight ring on back of flywheel to clear plate
    deck flywheel down an extra ~0.10" (or have fun last-minute clearancing the bellhousing like i did)
    notch bellhousing for starter nose, drill hole for starter mounting bolt
    notch bellhousing for front/top adapter plate to engine bolt head
    lots of bolt shortening for "blind holes" in the adapter plate

    Sh!t you have to make from scratch:

    Plate to cover old shifter hole in floor, to bolt new shifter base to
    engine/trans mounts and brackets (all four for FWD)
    subframe for front/rear lower mounts (you may be able to modify the stock one to work, i didnt bother)
    bracket for intermediate shaft bearing
    bracket and line for clutch slave (use camry slave, stock master)

    Specific tools/skills:
    BFH
    Welder / how to weld
    Torch
    drill press or punch
    hydraulic press
    grinders, cutters, nippers, band saw, etc etc etc

    Materials:
    Plate and angle steel in various thicknesses and widths (we ranged from 1/8" to 1/2" thick on this project)
    round or square steel tubing for subframe (we used 1" square 1/8" wall)
    1.5" ID 1/4" wall DOM for mounts (if you use the p/n above)
    1/2" diameter bolts for mounts (again)
    lots of M10x1.25 and M12x1.5 bolts in various lengths
    a handful of nuts, same sizes
    a few oddball fasteners, for example the bolts at the front of the subframe were m12x1.0 IIRC

    tips:
    the engine and trans need to come bothforward and up roughly 1". its hard to say precisely how much. the main issue with the stock drivetrain location is that the inner cv joints hit the K frame, this is the problem you need to solve. i wanted at least a finger's thickness clearance on everything spinning/moving. the frame rail on the drivers side also tries to occupy the same space as the trans by about 1/2". options are notch and box the frame rail, or hit it with the torch and BFH. we went with the BFH, everything seems to be just fine.


    i'll be happy to answer specific questions from anyone attempting to do the swap, however i hope that i covered this pretty well. if you feel i have forgotten something major, please let me know so i can fix it.


    i know the guys in NZ were first, but as far as i know this is the first FWD toyota conversion in the continental US. i give credit where credit is due, i ask that you all please do the same

                            sorry guys, no pictures yet. i ended up going to the "outlaw" dirt track race yesterday with my girlfriends father and all his buddies. i dont really like oval track stuff but holy DAMN do those cars move - on dirt no less!

                            anyway... yeah this is the trans that is used in the MR2 turbo and celica alltrac (minus the rear transfer). the alltrac guys run 10's on these all the time without mods... and those are pretty heavy cars in comparison! it should hold up well (i hope)

                            the gear ratios of this particular trans are:
                            First Gear Ratio (:1) 3.23
                            Second Gear Ratio (:1) 1.91
                            Third Gear Ratio (:1) 1.26
                            Fourth Gear Rato (:1) 0.92
                            Fifth Gear Ratio (:1) 0.73
                            Final Drive Axle Ratio (:1) 3.93

                            edit: added a few pics to post number 1
