Not many companies make a upgrade for the 4G61T, but there is still hope for those who need a stronger clutch.

Get a hold of a 6 bolt flywheel from a '90-'91 FWD Turbo Eclipse or Talon, then you can you use any of the Pressure Plates that are made for the DSM's.

A common upgrade is to use the '95+ Pressure Plate and disc. This combo should be able to withstand the torque that the 1.6L is capable of making.

Also replace the throw-out (release) bearing with a new factory Mitsubishi bearing. It is the same part number for the DSM's and Mirages.

[b:315mnc95]Pressure plates[/b:315mnc95]
MD739223 3K GT SL All
MD734041 1g DSM AWD -> 1/91 and all FWDT(?)
MD737970 1G AWD 1/91 ->
MD747748 2G FWD 1/94 -> 1/96
MD747787 2G FWD 2/96 -> and all AWD
MD742207 2G AWD All

MD745934 3KGT SL All
MD741736 1G FWDT All
MD741109 1G AWD All
MD741736 2G FWD (Exedy) All
MD747749 (DCC) All
MD745530 (Exedy) 2G AWD 1/94 ->
MD747778 (DCC) 2G AWD 1/94 ->

[b:315mnc95]Throwout bearing [/b:315mnc95]
MD749998 (all)

These are the numbers I found in an older version of CAPS, no telling how many of them have been superceded/combined by now.

My understanding is the 3KGT SL clutch disk is the one to use. Apparently the latest 95+ clutch disk you can buy from the dealer is a real POS. I have tested the stock AWD PP to be ~1750-1800 lbs, I would guess the 3KGT plate to be about the same (need to get one to test). The service manual gives a lower pressure for the FWD plate so avoid those.
