you said you have 90-93 dizzy.ecu..etc..
Are you sure you dont have obd1 already because the 90-91 teg is obd0 but the 92-93 is obd1 ..
And I would only trust the safc for low boost because the thing takes away fuel and you dont want that to happen when you have a turbo pushing more air.
Look into uberdata 0bd1----turboedit for obd0....Its free..all you have to buy is the chip burner...Its similar to hondata without the price
..And when you get the turbo set-up on..the first thing you should do is have it towed to a reputable tuner..tuning is costly but its worth it..
