the halfcut came with this thermostat and the bolts are rounded off and very farkin hard to get to, so i can't put the correct temp thermostat in for now.

Heaters are barely warm unless you give it a good caining. I can usually tear up a street sideways in second gear, but 3rd gear is very dissapointing as is 4th and 5th i aam lacking power forsure. (running a horrible low ratio 4.3:1 lsd)

well if you ran a taller diff it would be dissapointing in all gears!!
