Handling/drivechain Upgraded Ver.2.0: SPEC Clutch Kit w/flywheel and rebuilt gearbox

4387 19
hello to all,

Me again and this time is the clutch upgrade and gearbox rebuilt. If anybody may remembered I have put a LSD and 4.75 ratio final drive into a MTX-75 gearbox out of a 2006' Foci MK2, then bolted on a 2012 Focus S. Well, there was a minor issue with shifting, since I bought a used gearbox and I didn't check each gears' synchro-tooth. The 2nd and 3rd wasn't snappy and they went like cranky/clicky-click. I took the gearbox apart and found the 2nd and 3rd gears are on its way, as well as their slides,I need to replace them, then I found a partial MTX-75 without outer shell from scarp yard but it's 2nd gear are gone, I ordered a brand new 2nd gear from Ford then I used the 3rd and two slides from the scrapped tranny.

All set, by the time I received my SPEC kit, so I installed is by the way. I really need to replace it because I think I fried the clutch during track days.

OK, picture time !!

The no-good 2rd gear and slide:

The "partial MTX-75" :

Brand new Stage one kit and super lightweight flywheel:

Now the work-in-progress:
Auto part Automotive wheel system Automotive tire Engine

Auto part Metal

Auto part Bearing Tool accessory Differential Gear

Auto part Engine Automotive engine part Transmission part Clutch

Auto part Engine Mechanic Automotive engine part Auto mechanic

Motor vehicle Automobile repair shop Vehicle Tire Car

Land vehicle Vehicle Car Automobile repair shop Alloy wheel


Verdict:

Now the gearbox has been fully fixed/rebuilt, no more dramatic "clicks", shifting becomes or I should say restores back to stock but I can feel more powerful. However the buzzing noise from the final gear and mainshaft still remains. Well, the noise doesn't hurt only with the extra 20% torque. As for the clutch, I would say fantastic. The pedal feels lighter than stock but with more rebounds, shorter throw too. Thanks to the lightweight flywheel and short throw shifter, the shifting is way faster than stock. I need to start getting used to the new clutch and practice more.

Long work in short, I am pretty happy with the result and money I put in. I would recommend this mod to everyone.

Feel free to share your opinion,

I've read somewhere on this forum that the Duratec Ti-VCT need the dual mass flywheel for the engine vibration otherwise could lead to engine failure over time...

I think it was someone reputable from steeda explaining why they didn't have flyhweel for the TI-VCT..

Please correct me if i'm wrong...

How could steeda know this they havent tested it over a long time ?

The duel mass is more for weight mass and vibration on engagement then balancing the engine , the Alum flywheel will balance the engine the same if its a good name brand

well, my SPEC flywheel feels pretty strong and the very responsive engagement. I can feel the extra power sending to the gearbox. I even doubt that the chassis isnt strong enough to hold each red-line shift. I just installed a CFM rear motor mount to help stiffning the chassis.
