cost breakdown

the reason i choose ford gearbox (MTX75) over mazda3s (G35M) are because of this comparison.... (all prices are rough conversion using www.xe.com)

ford focus MTX75:
-------------------------------------------------
$750AUD - secondhand, comes with clutch, flywheel, ribcaging, 2 shaft, bigger center inputshaft.
$940AUD - QUAIFE LSD 1.5way
$990AUD - 4.62 QUAIFE final drive
$330AUD - 2 custom poly mounts (under battery and rear mount)
$400AUD - custom driveshaft (probably billet)
$150AUD - nitride treatment
$800AUD - clutch and flywheel
$200AUD - gear adapter plate custom made by CNC
---------------------
$4560AUD total stronger gearbox, more options and cheaper aftermarket support, shorter gear ratio


Mazda3 G35M:
--------------------------------------------------
$2000AUD - secondhand, gearbox only, smoother and well spaced gearing (except for 3rd gear), no ribcaging, and smaller input shaft
$1810AUD - QUAIFE LSD 1.5way
$1500AUD - KAAZ custom 4.58 final drive
$200AUD - 1 custom poly mount (i only need to custom the under battery)
$250AUD - driveshaft replacement
$150AUD - nitride treatment
-----------------------
$5910AUD total and i still need to spend extra $$$ to strengthen the gearbox which is still dont know how....


also MTX75 is being used on Mazda3 in Group N rally by Burmeister Rallysport, on drag race mazda3 by GoldenEagle, also being used on mazda6 touring car by tri-point engineering. altough the main reason they choose mtx75 is because of the aftermarket support...

im just hoping if i can successfuly do this conversion, it will be a good options and solutions for other mazda3 modifier...


NB: i dont have to do the LSD, and final drive.... but since im gonna open my gearbox, i thought mind as well...
