"you don't need to do your head studs until 290+ hp"

However, what it really depends on is how much boost is generated for a given tune/HP. Been running 18 Lbs at 265 hp since 2014, no studs.

Wanted to add that from what I have learned, detonation is the big killer of a head gasket. Run good fuel, don't let temps get out of control. I have been told over and over that these 1100 Turbos can comfortably run up to 20psi boost with stock engine internals, as long as fuel is good and no detonation. Get a tune from a tuner that has good safety backups, like a lower engine temp warning than stock, and a knock light. My tune has a very bright knock light with two stages, flashes for approaching knock, and constant on for full deto. Rarely do I see the light if running good fuel (Husky 94). As well, with the tune I have, keeping the rpm in between 8300 and 8400 helps keep knock away.

Here is a tip for you...replace the fuel filter every season. If they plug up even a little on a tuned 1100 T, you will start to have fuel issues.

I would say anything above 250 and I would do it, Speedwerx says it is needed with there 260 kit. I would rather spend the 800 more if a shop is doing It or 300 to know I am not going to be blowing a headgasket out on the lake and possibly doing more damage (warp the head, coolant in cylinder then next startup hydrolock it.) Then mid season have the sled torn apart doing the job when the sled was already half way there.
