[gsx rated98]

Hey everyone. Im not new to the DSM community, but am new to 1Gs. Whats the big differences in the 90 compared to the rest of the 1Gs. I do know the differences in t he 3bolt and 4bolt rear ends, and i know there is a difference in the Throttle Bodies. If there are other things, can someone fill me in. Thanks
Jerry

ECU is different in some respects. pin outs, fuel maps maybe some other things.

The 90 speedometer counts by 10s but starts with 5, 15 etc. 91-94 starts with 10 and counts 10,20 etc. They are calibrated the same, they are just printed differently. Its the easits way I now of to know off hand if its 90 or 91.

90s came with air to oil coolers where 91-94 came with water to oil coolers.

There are more perhaps I just can't recall anymore.

Is there any performance difference caused by the different TB?
