Hypertech Powerstats
Hypertech Powerstats Recently we've had a few requests for the 160* Tstat for LS1/LS6 Fbods and Vettes, and we've had a few people call back and say that the stat didn't fit. At first I thought that these people may have been 
but have since witnessed first hand on a few 02 Fbodies and on an 03 ZO6 that it didn't fit. So I called Hypertech and told them that the stats didn't fit, and when I measured the stock compared to the Hypertech, the Hypertech was actually about a half inch wider... hence the reason why the stats won't even fit into the hole. They said that is because the cars have the new water pumps from the 04-05 years.... then I told him that none of the cars were that old. Their reply was that the water pump was changed out, but then when I said it happened to my car, and I've owned my car since it had 3 miles on it, and it has never had the water pump replaced, he said they don't know why it doesn't fit, they must've put the '04-'05 water pumps on the cars. 
Anyone else have this problem?

Well, if Hypertech is correct ANYONE who has replaced thier water pump with a GM Pump since Feb. 03 IS going to have this problem. Plus, it looks like all late 01-03 LS1/6 engines used a new pump as well.

Lingenfelter sells a new style 160 T-stat for around $26 and I think I've seen Tbyrne advertising one for around $20. I've installed the Lingenfeltor one in a 04 Vette. It is just a t-stat and doesn't include the housing.
Oh yea, Vinci has one for $100.

Do they make any kind of thermostat conversion yet for the old water pumps to a normal type of thermostat. The prices on those things is way retarded. It's a friggin thermostat, not a gold nugget (which the manufacturers are apparently confused about).
