Hi,
Anyone that have a DIY description of how to rebuild a 7k Tach to a 10k Tach ? and from 4 cyl to 6. I would think that there is someone who has done this. Any potmeter adjustments, og parts that needs to be replaced ? I know that NHS does this, but would be nice to do it and just buy a new faceplate |

Only problem I see with a 10k tach face on a 4 is you are only using 1/3 of the tach face to indicate your rpms and you will have to leave off the redline or it will look dumb having the redline indicated at the halfway point. The 10k tach was for Porsche race engines that actually redlined not to short of 10k. My 3.2 tops out at 6,850.

I run a modified 911 tach at the moment: For me personally though, it's more getting the look to match the factory GT gauge set, as it seems most of them were fitted with 10K tachs (from trawling through the the PBase photos). And yes, I have to change the other gauges to match as well - but much like life, this car is a work in progress.... - Tony |
