Hey i need a new thermostat for my 93 Z28...should i stick with the 160*...or i was looking at a Jet performance 180*...which would be best??

[BonzoHansen]

are you reprogramming the computer to compensate?

[GMkidd91]

umm would i have to? i know the 93 isnt very computerized...i wanna switch to a 95+ opti and computer setup

[greenformula92]

go with the stocker....if you go lower you need to tune accordingly

[GMkidd91]

well the one in the car now is a 160...what would happen if i went to a 180?

[Tru2Chevy]

Does the car have the stock tune in it? Or has the chip been reprogrammed / replaced?

180* is stock for the LT1. Swapping to a 160 won't do much good unless you reprogram the fans to turn on at a lower temp as well.
