Need some help
 

Alright guys, i just joined the forums, and first off its good to be a part. Ok now on to my question. So i'm a mustang guy, thats all i usually work on, thats what i own right now. However the mustang isn't the greatest on gas and i would also like to experiment with different cars. Anyways i found a 93 fd on craigslist. It has a 102,000 miles and its all original twin turbo 13b. Thing is, the only Japanese cars i really know about is nissans. I know a little about mazda's but not near enough to know what to look for when buying. I know the very basics on how a rotary works. So, im looking for any advice anyone can give me, on performance upgrades what to do for rebuilds and just general advice about these cars. any info would be appreciated!
