I would suggest like a T3 off of a Z31. If not that, then a T3/T04E 50trim with a .63ar turbine housing. The bigger the turbine ar, the slower the turbo runs and later you make power. Different trims determine where the turbo is efficient. The bigger the compressor ar, the more the turbo will flow. You will have to read more on these in one of the two books I posted earlier. Don't get anything big because the more the turbo flows, the more power you will make. For example, a T04B will make x amount of power at 7psi, while a T28 will make x amount of power at 14psi. These are hypothetical numbers, but you get the point. Safe boost depends on the compression of the engine and a judgement by you. How well does the engine run? People have turboed some pretty high mileage engines and have had good results. This doesn't mean you will, but good tuning and care before, during, and after will definately be helpful if you want this to work. 5psi from a decent sized T3 will require no fuel or ignition mods and will provide somewhere around 169whp. This seems small, but remember, your car right now is only putting 124whp down if it is making factory hp. Some mods you might want to think about are a walbro 255lph fuel pump, 300zx fuel filter, NGK plugs, 3"catback is good for a turbo setup, cone filter, new o2 sensor, and all the other tune up stuff. Your best bet for an engine is to rebuild while you run this one w/5psi. All you really need to do is add some forged pistons and take it out about 0.0020". The crank and rods are forged and can take somewhere around 18psi maybe more. Stock injectors max out around 200whp. Stock MAFS maxes around 250whp. Thanks for the heads up Turbo2nr. I was reading in about the SAFCII. It has 12 ne tuning points and a deceleration menu(good for hotwire MAFS cars like ours to run vent-to-atmosphere BOV). It sounds like it is pretty good. Hope I helped.
