You may very well have a 3.73 in an auto. This topic came up for me not long ago when I went to the junk yard to find an 88iS automatic car, which had a 3.73 as well. I believe starting with the 89' is when the automatic cars had the 4.10.

 Okay because I thought these had 3.73's in the auto also, I know my '89 auto was a 4.10 and the PO of this car says it's a 3.73You may very well have a 3.73 in an auto.

 who knows what's been swapped into these cars over the years, but i would think an e30 m20 auto with a 3.73 would be readily identifiable via how miserable it'd be to drive.
 
 but then, i hate both autoboxes and numerically low gearing.past:

 loud and high at 65 sounds like a 4.10 to me, but we'd really need to know rpm at speed in top gear to figure it out. or just lift the back end and spin things.past:

 Just spent my break refresh money on a new watch.. I guess new pads, rotors, fluid, and front rx7 BBK will have to wait :/Last edited by Toodaloo; 03-21-2016, 03:31 AM.
