Different RPM Ranges?

[WhtEclipse705]

This probley has been answered before, but i am wondering why all the gauges on ebay have different rpm ranges. and where is a good place to get gauges that actuly go to 9 grand on the rpms? cause i am sure putting one with only 7 or 8 grand on there is going to not read correctly. thanks..

Don't you hate it when no one replies to your post.

The reason for the different tach readings is because of the different engines in the cars. One for 4G63T, one for 420A and one for 4G64.

Hope that answers the question well enough for you.

on the 420a I think that M/T and A/T have something to do with it. A/T going up to 8 and M/T going up to 9, not 100% positive, but I think so.
