Dude... Its totally doable. Look on ebay and get yourself a T3, and an "E6" turbo 2.3 exhaust manifold. The intake manifold you have now will be fine. The **only** difference between the SVO/TC internals and the NA 2.3 internals are forged pistons and slightly better rods. No, you won't be able to blow over 25psi as I do in my TC, but 10 will be fine. You have the dual plug head, but no big deal, the E6 manifold will still fit. ALL 2.3 blocks at least have a boss on the side of the block for the oil return line. MOST 2.3's already have it tapped. The NA 2.3's just have a plug in it. You will need the oil return line from an SVO or TC to use it. As far as electronics, if you have a 90 LX, I'm nearly certain that you can repin your EEC harness and just bolt in a turbo 2.3 computer. The PE is the most desirable and go for about $150 on ebay, but an LA3 or LA2 will work **just** fine, and can be had for $50 on ebay. Of course, if you run into one of these cars at the junk yard, you can gank all the parts for cheap. By the way, I'm nearly certain you can repin the connector on 2.3 stangs until 91. After that, you will need to get the entire harness from the TC and lay it in alongside the stock harness. If, and ONLY if you are very serious about doing this, PM me and I'll get you more info about the repinning of the EEC harness. You will be wasting my precious time if you aren't serious though. Hope this helps.
