1991 monty max 4x4. V6 to 4g swap & RHD. need 4g fit aide
ok. so im new to jap vehicles and new to 4x4's, but not to autos. esp not 80's vw's
audis and bmw's. so im a recovering german car enthusiast.
so ive had this 1991 mighty max for a few years now, bout a year an a half ago i stuffed
the nose into a lift gate of a box truck (dont ask), so its needed a front end for a bit.
Ive always wanted a montero, love the noses. so im putting a monty nose on in place
of the square headlights.
And after digging into the front end w repairs and noticing how simple it would be to swap
the steering over from LHD to Right hand drive (its just a matter of replacing the steering box,
idler arm and tie-rod link rod with the RHD mirror-image units from the UK etc, the entire brake/clutch
pedal assembly moves over to the right side of the firewall. piece of cake.)
so ive got a new RHD idler arm in the post, shud be here next week. thatll tell me if they are
indeed the same bolt pattern and then ill have a steering box and tie rod link shipped over.
i havnt looked into getting a dashboard, its gonna be pricey to ship such a large part, so i might
just make a custom aluminum dash w montero gauges and center console, idk yet...
So, i want to shitcan the crappy V6, ive always preferred 4 cyls. obviously id love to swap in
a turbo 4g, but ive done the turbo thing and im just after a nice reliable modern DOHC 16v.
i was gonna swap in a toyota 2/3RZ after driving one super torquey, then i read the newer 4g64's
are about the same output and it'd be nice to keep it all mitsu. this brings me to my issue;
after reading thru the 4g RWD thread i encountered some forgotten issues.
my plan was to get a 4g outta a 01-05 eclipse and install that with an 87-89 montero
4g transaxle/clutch/starter. heres where i hit the speedbump.
i forgot about the narrow/wide block thing.
-So the big Questions;
-Will a 01-05 eclipse block bolt up to the 87-88 montero 4g bellhousing???
(i believe the montero's/max's ran the narrow block/bellhousing 4g's...)
-Im seeing 3 different FW/crank bolt patterns, 6, 7, and 8 bolt cranks.
i need to know what flywheel is gonna work on the 01-05 eclipse crank
and montero bellhousing??? (if the 4g monty bellhousing doesnt work im going to
make a new bellhousing to fit what i need. i just need a flywheel that'll bolt up to
the newer 4g64 crank and work w a 4WD/RWD setup...)
i was gonna run all 4g montero clutch stuff until i noticed the different crank bolt patts
im sorry for the long read just tryin to explain where im at.if anybody has any tips/info/recommendations
please feel free to school me.
i dont know pic posting yet, but ill tryin get on that asap, we all know w/out pics its not a build......
thanks for any help!

weekend update one day late......
my bad been slacking on picture posting:
so i made a template of the OEM firewall re-enforcement plate for whatever stupid reason
as afterward i realized that its a totally different layout on the right side of the firewall...
whatever.
Attachment 21999
and i started to lay out the steering column port, its actually kinda in a similar spot as the
LHD template, im not going to drill/cut anything until the box arrives and i can move the
steering wheel permanently on the RHD-side. then i can see where the hole needs to go.
i dont think there is ANY kind of flex or u-joint INSIDE the firewall, the 1st on the column is
just past the firewall in the engine bay, the 2nd is down at the box. so the firewall hole/port needs
to be in the correct spot, then the shafts bushing/seal unit can get bolted to the firewall round it.

But i got the clutch located, hole cut and stud holes drilled, the support plate cut out, ready to spot-weld onto the wall.
mounted the pedal unit and started fabbing the support bracket that gets welded to the firewall under the windshield:
Attachment 22005Attachment 22006Attachment 22007Attachment 22008
and got my wiper linkage pulled out to move over. what a bitch. only x2 of the x6 nuts were NOT rott-welded onto the studs
managed to get a small set of needle nose vicegrips into the raintray and grabbed onto the bases, after i ground off the tip
of the studs flush with the nuts, so as to ease removal and not have to spin the nut over crusty blown up rotted metal,
but still saving enuff of the stud to re-use the linkage assm.
the factory punched out the 1st hole pattern for the wiper-stem & studs of the RHD set, but the furthest set is not theref
or whatever reason. so i transferred the pattern over and drilled out the stud holes, ive yet to cut the big slot for the stem.

you can see there is this drip shield thing to cover the inlet of the blower motors fresh air intake, ive gotta cut that out
because the wiper linkage doesnt clear it. i was going to tryin drill out the spot welds, u can see them in white paint marks
but then i thought better of possibly blasting holes thru my cowel and firewall, so i think im gonna use a cutoff wheel and
slice iit out flush under the cowel, then weld a flange back on it and transplant it to the left side for the new blower intake.
And the wiper motor has to get moved over as well, so i cut out the part of the firewall/raintray wall that the mounting
bosses/weldnuts were on (which i only did when i couldnt reach the 4th of x4 wiper linkage studs w the vicegrips, like a jerk)
so im swapping the pieces of the firewall so the Left side looks how it would OE RHD, theres a funky C-shaped indent where the
motor mounts up to the firewall, see:

thats all for now, more soon.
i just hope this bloke i ordered the steering box from gets that expedited ASAMFP. i paid him $315 for a $100 steering box, a
set of p/s lines, and a RHD accell pedal. he only wanted like $260 shipped i sent him the extra $40 to get him moving...
paid him sunday nite (early monday mornin in UK) but i dont think he made it to the post. i just hope expidition gets it here
by the weekend. im not gonna hold my breath, the idler arm still aint here....
ill keep yall posted tho fo shur.
nite nite

i still need to make two bosses to bolt the tabs on top of the brake pedal assembly to, but i haft to wait
until I patch the old blower motor intake hole, because one of the tabs is under that hole at present...
i gotta go to an appointment at 9am, so im done for the night/morning. ill be back at it later on.
hopefully that steering box shows up in the next few days. im ready for it. :)
