How long does it take to install? Is it something I could do myself? Any idea how much to rebuild that turbo? Is it only capable of 7psi boost? How much gain from my NA motor would it give me? Any additional wear on the motor?
Sorry for all the questions, just want to know what I am getting into.
Wooaa! Thats sweet, If I had any real money or need I'd be bidding against you. I put a similar setup on an old 83NA that I used to have and the power increase was very dramatic. I would guess that the car will be in the low 200hp range with the torque increase being ther biggest thing that you will notice. I have no dought that the turbo will need a rebuild but that can be had for 350 to 1000 depending on what you want done and how fast you want to go. There are several guys on this board and on Hybrid Z that have ties to rebiulders and can really help. Also I didn't see anything for extra fuel. Did I miss it? I'll look again later.
Get a stock ZXT morot and harness and graft it onto your car. Much better drivability and response. Why drive 70's technology, when 80's is just as cheap and gives you more fuel mileage!
That system gave me about 17mpg daily driving in my 240, but I got as low as 5mpg! On the other hand, the stock 280ZXT setup in there now gives 20+mpg easily, and rarely have I been close to single digits (I got 12 once...)
Blowthrough turbo carbs were state of the art back when that system was new, but even then, Haltech was out there, knocking on the door for better fuel control...
Gotta agree with Tony on bang for the buck go with the complete zxt motor. Also I'm not sure what type of head is in your year zx is but if it doesnt have a P90 square port head you may need to add a new head into the cost equation.
