You will need a stage 3 clutch. The stock 2.3 ranger clutch wont handle any boost. The fuel pump will need to be swapped for a 255 lph, and unless you acquired the turbocoupe's air intake you will need a larger MAF. I think the 95 ranger has OBD I so you will need to find a tuner that can flash your OBD I ECU so that it can utilize the new fuel pump and MAF. It will probably have to be re wired because I wouldn't think that an 87 engine would be a direct swap with a 95 ECU. Could be though IDK.
A better option would to just swap over the turbo components without the engine. (Including larger fuel injectors) Then you will not have to re wire the ECU, just flash it.
The turbo ranger forum guys know a lot about that stuff, might want to check with them.
