get familiar with your engine. read up on turbos. 2GNT.com - home has info. ill tell you what you will probably want to do and why.
-peice together a turbo kit yourself, it will be cheaper
-get your turbo of choice, (i would get a 50 trim or something small) get a turbo manifold with a 38mm tial flange, or no flange if you get an internally gate turbo. get a tial 38mm wastegate if you get a turbo without an internal gate. find a welder and have a downpipe made and the rest of the exhaust.
-get an intercooler (turbo xs will be cheap and get the job done), get a piping kit that comes with good silicone couplers (4 ply) and t bolt clamps. (usually can be had for a little over 100 bucks on ebay.) make sure you flare the ends of the pipes if they arent already or you cut the piping.
-get a blow off valve with flange and have the flange welded on your piping.
get a SAFC and run a few pounds of boost. im not sure what the injectors are good for, but i think you would need a built engine before you max out your injectors. you could get some 550s to be safe though.
