Upgrade help

[Toyo Truck]

Hi I am a newbie here. I need some advice and help if I could. I have a 1980 Toyoace flat tray truck with a 5R motor and 4 speed column. I bought a 22R to upgrade to (I thought my last Toyota conversion was 5R to 22R which was a piece of cake) I have since realised that it was a 20R to 22r that I did. Now I am stuck. Can anyone out there give me some advice on how to fit a 22R into a 1980 Toyoace truck without massive conversion costs? I have a Dyna and a Hilux for parts, I would prefer to go with an auto if it is possible. Cheers, Darryl 0412-461-774

the biggest downfall is a hand or park brake.

most gearboxes the 5r motor was fitted to the hand brake drum is mounted on the gearbox .

where i live in queensland only a gearbox of such configuration can be used, as a modification to move the hand brake to the rear axle is a pain and not legal.

the 5R motor has a removable half bell housing, unlike the 3R and 12R which have a half bell housing cast as part of the engine and with the 5R because of this makes an engine swap a little easier.

when a holden or ford motor is fitted in a dyna to replace a 5R a alloy adapter ring is used, this replaces the removable half bell housing.

when i was in high school i did work experience at an engineers and he made adapter rings to fit different motors into tractors, cars and VW buggies using a automated oxy acetylene set up that could follow a black line drawn onto white paper. he would trace the outline of the gearbox bolt pattern and the same of the back of the motor and the machine would cut them out of plate steel in seconds and he made it look easy.

personally i have a 1962 toyopet stout fitted with a 5R motor, timing chain version (there is a timing gear version that has more issues prone to failure) the motor came out of a dyna truck that had over 900,000kms on the clock and has never been touched apart from a head gasket.

the timing chain version is virtually indestructible and offers the same HP and torque as a 22R and to rebuild or replacement of the 5R would be my option .

the quickest and easiest way to tell the difference between timing chain and timing gear is to feel under the exhaust manifold the PCV positive crank ventilation, as the timing chain version the breather has two bolts that hold it in place and the timing gear version the breather just pushes into a round hole.

my goal one day would be to fit a little SC14 supercharger off a jap import at low boost and this would give more power at less cost than any engine conversion and as the 5R are built to use LPG unlike any replacement engine would be
