any car can be a sleepr if done right. BUT how much money do you want to spend?
im guessing your not planning on keeping it auto.. and auto to manny swap isnt tooo expensive, but def not cheap.

im also guessing you want to swap the motr, but keep it streetable/ reliable... so if iremmeber correctly that would be the fwd avenir(bluebird) sr20 ? fwd turbo... make it fun and you can build from there.

i like the styling of those cars, lowered a bit they look great imo.

i would like to see the body kept stock, rims + lower is about all is needed imo.
