maximise mcx 290 or rebuild.

she has produced well but i thirst for more ponys and was wonder if there is a cheap way, like turning up to 18psi and run 98 ron, 100ll, 50/50? or wait and rebuild whole engine too 500hp and at what cost.

No problem running 18 psi, but I never hold for more than 8-10 seconds. I'm thinking of do some change to the engine, carillo rods, pistons and head studs, around 2000 dollars + work. T19 turbo should be good for around 22-25 psi, 360-380 hp possible ? . New turbo garrett 2871 around 1300 dollas, maybe possible to reach 400 hp. More power ?? I'm thinking very expensive

I would definitely do pistons, rods, and head studs especially pistons because all the new ones crack at higher boost ask me how I know LOL
I just parted my sled out and have a built motor sitting here looking for a new home and a GTX 3071 for sale also it is capable of 560 hp and the motor made 500 hp
