the cheapest way to go turbo is to buy a halfcut(half front of car) from import wreckers of a 'bpt'..(which is the type of engine)
ur standard engine assuming its a 4 cyl not a 6?
should be a 'bp'...so basically same engine but turbo.
other wise turbo ur standard engine would involve buying new ecu-(computer), all the pipe work,stronger internals and getting wiring done for a start.which ends up being alot of money,if ur just looking for bit more out of ur astina as is.
hope this helps u out abit,im sure some1 can ellaborate abit more
N/A = naturaly aspirated(non turbo)
ecu = cars computer/the brains
gtr or gtx = the model of car which the bpt moter comes out of
HD = heavy duty
as suggestion best thing is to spend couple hours on search
