best mods for xtra 65 horse or so?

[tommyinla]

hey...

i've got an 85GT that i've been driving around and have decided to throw some money into it...

i've just picked up a turbo coupe rear end (8.8", 3.55 or 3.73 gears - not sure yet, disc brakes).

i want to know what you guys think i should do to get the car up past the 250 hp mark... between 250 to 300... closer to 300 would be nice

the car is bone stock with about 107k miles and i don't really want to tear into the engine too much. i'm gonna do the exhaust soon with dynomax super turbo or ultraflos and was wondering whether the best bet would be to throw on a set of heads or what...

thanks
