"Here's the list of things you need to do the conversion on a 1g. (1991-1994) it varies slightly for a 1990 so I'm not too sure on that one.
This list is the culmination of my research into making a non turbo into a stock turbo dsm safely without blowing stuff up. I do not have a how to yet because I myself am still working on it. BUT in theory it will all work. In reality, I still am not sure:
-throttle body
-throttle body elbow
-tap a hose barb into the intake manifold (for BOV line)
-uic hose
-lower ic hose
-stock sidemount ic
-turbo intake cam (at or mt depending on your tranny, exhaust cams are the same)
-stock 1g exhaust manifold
-stock 1g downpipe
-14b turbo
-stock 1g o2 snesor housing
-turbo ecu + wiring harness (the ecu plugs for the turbo ecu and several connectors for the mas, fpr solenoid, knock sensor and injector resistor pack)
-450cc stock turbo injectors
-turbo fuel pump
-turbo mas
-upgraded clutch if you have mt (act 2100 at least)
-turbo fwd oil pan
-knock sensor
-injector resistor pack
-all lines to connect turbo to water source off the head (turbotrix)
-all oil lines for the turbo (can be bought from turbotrix)
-new head gasket
-timing belt change
-rods, pistons & rings from a 6 or 7 bolt engine (depending what year your car is)
-block rework & head rework
-fuel pressure solenoid
-knock sensor
-new o2 sensor
-turbo mas (if getting a 2g mas then you need to do the 2g mas conversion) "
