Altezza A/t Turbo Conversion

[Draltezza]

Here's the thing, i got a hold of a hks gts turbo kit, but i know that the compression oh my motor is not turbo friendly, so read some were that if i get a head gasket that lowers the compression oh my motor, it can be more turbo friendly without going with the big mods, like piston and roads. so i turn to u guys to tell if its true or not?, if it is how much boost can i get into my motor? the head gasket will lower my compression to 10.6:1

P.S.: thanks for the help

You running the 5AT or 4AT?

Should be able to handle 250hp no worries. There's one guy who's been running 7psi on ACNZA for a few years now without any issues on his 5AT.

i have been reading and researching on the net, and i came up with some interesting info, correct me if im wrong but the 5AT code is E650 so is the same tranny that come on the is300 but modify so it can cope with the 2jz, when i found that look up the toyota tranny to see how much toyota saids the tranny can hold up, and what i found was that the tranny can hold up 325 whp, in a other site said (im not pretty sure about this) that it can holp 400-450whp cuz that same tranny can be found on gs300
