What do you plan on doing? I have a 1990 Integra LS 4 door, which I plan to swap a b18C5 or C1 into and add a Prelude tranny... I plan on going all JDM Japanese Domestic Market such as headlights, taillights, windows etc... As far as your car, 225k that's a lot of miles, who did you buy it from? What trans is in it? Auto or Stick? You will first have to buy lower compression pistons such as 8.5:1, get forged rods, and most likely get better cams and vavletrain, I maybe wrong, I dont do Turbo, I'm an all motor person but what I've heard get the bottom end (crank, rods, pistons, rings, etc) bullet proof. so you can run like 10 or 15 pounds of boost, also re-sleeve the block... like I said i'm not much on turbo's and superchargers unless the car already has it, stock... I love all motors, you will need to get a cat back exhaust also with a Header adn free flow catylitic (Spelling) converter. An ECU, electronic control unit, fuel injectors, fuel rail, fuel pressure regulator, fuel pump...
First off all just rebuild the B18A1 that's in it, Get the Trannsmission looked at... if it;s an auto dont bother just make the car look pretty.... Later
