ok - as it seems the search button isnt working - info in a nutshell
st162 - 3sge non turbo twin cam - front wheel drive
st165 - 3sgte turbocharged all wheel drive ( its a gt4 - the original )
5sfe is a good motor if you like economy and less than haert racing performance - its " twin cam " head is the econo version - built for cheap running and not sporty performance
3sge - has the G series twin cam head which is more tuned to performance respponse and fun .. much better
youll pick up a post 1990 celcia for less than 8k - but expect it to be in ordinary shape , and 5sfe equipped .. for 4 K more you can get yourself a cheap Gt4 ( mine cost me 11 grand )
if you want sub 8k prices - get yourself a st162 - they are mega fun and responsive and have the better 3sge motor installed .. Still front wheel drive but youll get alot more performance related fun from one ..
