Yes!!! Only thing the higher the octane is it is actually harder to ignite, not slower to burn. And dumping 110 octane in a untune care will result in a loss in performance.
What year wrx do you run? I got a 2009 sti at the moment.
Light primer strikes with hirtenberger, the Timney doesn't have a heavy hammer spring, you could change the spring if you wanted. If you want to spend 4K+ on a rifle and choose to feed it some cheap ammo cool, it's your gun. It's not like you can't change the barrel, isn't that one of the reasons these rifles are so popular? The modularity of the design?
04 rebuilt with Manley forged pistons, rods and stroker crank (from a 2.5L motor). Still on stock turbo for now but did 197hp to the wheels on the all wheel drive dyno in Calgary when I had my tune done. Looking for 300+ to the wheels when I stop buying guns for a while and put some more into the car.
The index pin is at 6 o'clock instead of 12 o'clock so a standard AR barrel won't just drop in (unless that was only with the MH but I'm sure I'll be corrected if I got that mixed up).
It could be done but it's not as simple as just buying a regular cheap AR barrel. You would need to have a machinist move the pin for you first.
When I rode with you I thought the next investment should be a roll cage...![]()

Pretty nice! What compression are you running?
So many ass-blasted people in this thread.
Buy what you want.
Enjoy it how you want.
Its your money
