I have 4 trannies

86 951 - LSD and cooler
86 951 - NO LSD and Cooler
86 944 - Both with coolers.

I am pretty sure I read somewhere that all of the 86 models had cooler but differed in LSD and non-lsd.

The 86 has forged. There was some mixed information saying that the 86s were the only ones ...... but later I recall reading that all the turbos have the forged rods. Although the casting codes are different (hence the arguments). I am pretty sure that it was thought that the 87's did not have forged but I recall reading some info that the casting codes were different but in fact they were still forged.

The only NA's to have forged rods were the 83 and part of 84. As far as I recall.
