You can find the stock setup off an original turbo mirage OR I believe there is a setup off a 4g or space van that might work(?), someone will chime in soon to tell you the details on that.

Had a:
1991 Eagle Summit ES Hatchback - 4g15 12v 5spd
1991 Dodge Colt -4g15 12v 4spd
Have a:
1978 Oldsmobile Cutlass - 468BBO TH350
Round 3:
1990 Dodge Colt-4G63T 5spd

I would like to do the same, what are the main parts that we should take from the donor car?
*Rear rotors
*Brake calipers
*Brake caliper brackets
*Hand brake cables
*Brake pads and parking brake shoes
*Brake lines? from where to where?

What else?? Hubs??? Or maybe it's better if we take off the whole rear fwd subframe??
And what about other cars that we can use as a donors? I have heard that 89-90 Galant with rear disk are the same, but not in the brake cables
And I have a side question for this, it's this conversion really worth? I DD my Colt and even with the 94' Vista front brakes sometimes I feel that it's not enough, I don't know if it's because I still have the stock brake booster/master cylinder or it's really not enough, do you guys think that a GVR4 front brake conversion would feel a lot better???

91' Mitsubishi Colt 4G67T FWD "The Minion" - 12.26@118
94' Mitsubishi Galant GS 4g63 Swap "White Unicorn"
95' Eagle Talon Tsi FWD "Ernie's car" - 13.92@104 *Rest In Parts*

If you have the stock base model 3.5:1 booster, then you have to upgrade to the Sedan (1.5L, 1.6L) and Turbo (1.6T) disc brake boosters, that have 4.0:1 ratios.

Also, if you do not have the matching size of master cylinder for the brakes to go with the larger piston calipers or even dual piston, the brakes will not be working efficiently and properly, thus increasing effort and increasing the pedal travel.

Rear axles are the same between a turbo car and a non-turbo car EXCEPT for the tab where the parking brake cable intersection the axle. You can weld in one fairly easy. Galant's must be pretty darn similar, because they have the same rear calipers. If DSM brake cables work, why not the Galant? :wink:
