hi

i cant seem to find information about what would need to be done if i was to put an a14 or a15 into my 120y

would there need to be engineering done?
what brake upgrades would be best done

what if i was to put a 12a rotary into it
i would imagine 12a would be lighter then an a12

what would i need to do to the engine mounts for any 3 of these engines

for now the a12 will do
but in the future i would like to see something a bit more hearty in my 120y

thanks in advance

a14 and 15 bolt stright in as you have newer a12 mounts (dizzy in the middle of block.

You might want to upgrade radiator in hot weather but brakes should be just ok. I would either look at s13 upgrade brakes onto your 120y struts (popular conversion now) or stanza struts conversion for better braking power.

Also gear box 56a is just ok behind a15/a14 but that depends on driving style. you should look at 60a 4 speed but these get hard to find and expensive.

Use the engine brackets off the A12 you're removing, lower new engine into place, connect the accessories. That's it. the gearbox will bolt to the back, the radiator hoses line up, the coil is in the right place, the fuel line is where it needs to be. It's that easy. the only difference is in the height of the block, but the standard header will fit the stud spacing, & with any luck there'll be enough clearance so the exhaust doesn't hit. Most people doing this fit extractors & get a new exhaust made to suit.The only problem is the head has a different port size from the A12 to the A14 & a different stud spacing, but the stock A12 carby will fit onto an A14/15 inlet manifold,& is a better bet than the later carbs (less emissions related parts). As for getting it engineered, checking the engine number is no longer a part of the NSW registration inspections,or you could contact an engineer & ask what he'd need done. As it's such a minor change, I don't think they'd need much. My recommendation would be that if you're in Australia, & you don't already have them fitted to the car, get a set of struts with the PBR calipers & discs. these are the same basic shape as all the Girlock brakes on later Stanza's & 200B's,& used the same caliper & brake pad as the Mitsubishi Sigma. I was nearly rear-ended by a Police car once in my 1200 wagon with these brakes fitted, as I stopped much quicker than the Police had expected.I was doing about 120 k's in a 100 zone & they'd just radered me.Hiding in the long grass in the centre divide of the M4 at Penrith.########.

Jason, please could you put in your profile where you are, Country & State wise. It helps us give you the proper advice

thanks very much
Thats the information i was after

Ill spend some time on my profile now
Cheers
