I live in Atlanta and am in the process of buying a 97 eclipse GS with a blow engine. I would like to replace the engine with a new or low mileage 420A—preferably turbo. I don’t have many contacts for this type of thing. I am trying to figure out if it is worth it, and how much it will cost--so that I can make an offer on the car. Any suggestions how I should go about finding a 420A here in Atlanta and how much one would cost?

I'll help ya do it dude, Brunswick GA :)

i'm in powder springs which is near marietta and kennesaw. by the way, there is no turbo 420a. you'll have to buy the kit for that.
later

for a custom turbo rebuild and install your looking at 4-5k for a fully built and rocking 350-400hp car, thats if u only have to do the usual rebuild, bore and head rebuild stuff if the block is gone u may need to find another which would jack the price up a bit,

u should get all your gaskets form forum dodge, 5% above wholesale for dealer parts, figure about 500$ in replacing stuff, gaskets, timing belt accesaries,

rods eagle rods 350$ pistons 450$ for je and less for weisco pistons,

figure a good 400$ in machine work to rework the block,

head rebuild about 500$ for upgrades and machine work

figure 2k for a custom turbo setup if u know what your doing otherwise grab a kit form star or hahn for about 2600$

and u should be good to go new clutch for about 260$ if u geta pt cruisar style or whatever u choose clutch masters stage 4 etc. depends on your choice

blow motor 97 gs id give them no more then 3k for the car i paid 3300 for my 95 esi running and in good condition im rebuilding it at the moment though
