you mean gyro's full t28's in stock housings or do you mean real deal t28 all arounds? either way, id be interested in knowing, how much boost can gyros t28's pump out? i have je forged pistons but mostly stock engine. will they be able to boost enough to kill my engine? (i hope so, cause i dont plan on upgrading turbos again) oh yeah, i got the super t28's but i'd be interested in hearing from anyone with gyro t28's
