    1972 Toyota Crown MS 65 2JZ-GTE Conversion

    hey guys long time reader new poster, my names nathan and doing an apprenticeship as a heavy duty diesel fitter at the council in murwilumbah, ive bought a 1972 Toyota crown ms65 a few weeks ago for $500 (has minor rust, engine runs) and decided that a 2jz would look better in the engine bay, so ive bought a Toyota aristo half cut in brisbane ($3100) im trying to keep all chassis work original so if i ever want to re-sell it as a classic, will appreciate any feedback n idea's.

    Are you going to keep the stock twins? They actually work really well.

    In addition to the standard sump issue in older M-cars, I am almost certain the stock twins foul on the steering box - even moreso being a PS box.

    That said I'm a fan of the twins also as long as you don't have to work on them! IMO best to replace while it's all being done - which along with a sump is one of those things that makes a JZ conversion a lot more expensive than it looks.

    if your going to drive it and own it for some time put a rack in it and never look back, otherwise put a big single on and it steering like a rubber dog turd will be someone else's problem later

    yeh ive bought a supra (rear mid) sump to go in place of the front sump as it fouls on the front crossmember (the rear sump will be modified for it to fit cause the steering is in the road), and yeh the twins foul on the steering box ive come to decide on whether to go highmount straight up and put up with the shite steering or go the rack but i cannot find any info on what type of rack to use but i have heard that if you do use a rack it does come under chassis modification and its harder to get blueplated. (brakes will be upgraded if i can find a ms112 rear end although eb falcon disk fit straight on apparently but a caliper bracket has to be made.

    Was going to add more photos b4 but computer crashed so here they come =)

    The new Supra sump $120, would have liked a true mid sump but there's better luck winning the lottery then finding one of them let alone it doesn't have a oil return

    This is the Dilemma we have reached today, the engine is still to high at the front and the gearbox cannot go any higher at all.. the only options i can see working is the do what JZK25 did to his 68 and cut the rust spot out (cannot be seen in photo due to lighting) and shape the plate to "by chance" fit the harmonic balancer in with the 10mm requirement or to buy an after market racing harmonic balancer that are alot smaller in diameter and will allow me to lower the front of the engine but for around $400 i think its pretty steep but in saying that i dont want to modify the chassis "cut the rust spot out"

    i used peugeot rotors (604? can't remember offhand) and landcruiser 4pot calipers on my corona, which should be essentially the same. needs minor bit of metal taken off for clearance, but all that fit under a stock set of rt104 rims.

    ps. steering is its own mod plate (if you are in qld) but nsw i have no idea re engineering.

    Don't worry about cutting the car up. If anyone was collecting these they would have done it already. cut and shut till it fits

    Just be aware that if it has an AMI (australian motor industries) badge on the front quarter panels, behind the wheel arches, then it is fitted with an australian made 'banjo' diff. As it is 72 there is a good chance it is one of the australian assembled ones. The banjo diff is quite possibly the weakest differential in the known universe - axles, crownwheel, spider gears are all ultra weak.

    Any of the solid axle rear ends bolt straight up, and the jap rear ends are stronger and have discs as you already know.

    There isn't any budget lsd for the jap diffs, but the borg warner 78 from the r31 skylines is the right width, has 28 spline axles and can be stuffed with an lsd centre easily.

    Or just weld the centre up.

    Front brakes off a ms123 are 255mm ventilated - you just swap the whole stub axle over - and whilst you're at it swap the steering box and whole drag link assembly as the 123 bits will be fresher.

    Alternatively, swap over a camira or daewoo rack - they will work best with the front end geometry.

    Pedders do lowered springs for them, and adding a second sway bar to the front and one to the rear make them handle much better.

    Great project !

    just imagine if you went down this route Seano - bit of a tidy up, a sensible, modern engine conversion and then some brake upgrades

    Yeah - effectively the same manufacturer. They have the steering arms attached in the centre of the rack which works with the stock suspension and steering geometry.

    I used a 323 rack which is a conventional unit, but am yet to drive it. It may be ok, but if not ill swap it over.

    alot of great info, what do think ill have to change for the (r31) borg warner diff to fit because that sounds like the way to go?

    It's not a bolt in or anything, but it's not that difficult.

    You need to swap the crown lower control arm mounts onto the bw - just make a basic jig.

    The crown only has a single upper link, and it is nearly over the centre of the diff. As the bw has a cast centre housing you can't easily weld the crown mount on there.

    Make up two new upper links and weld New mounts to the diff housing and chassis. ( I have the adjustable upper links left over from mine you can have for $50 if you want)

    You'll then need a custom tailshaft too obviously.

    You can leave the axles as 4 stud, or change them to 5 stud to match the front.
