what up everyone, my name is Mike. I have a 1988 Honda prelude si w/ 4WS. I love my car no matter how many times people say its an old car. Its in really good shape. Now i have some ideas on to make the lude push out some horsepower. I was either thinking of changing the head on it and putting a gsr head on it and make it a b20-vtec. my second idea is just to buy a turbo and not use that much boost but then build up the engine and turn up the boost. As for aftermarket parts that i have on it now is i have AEM true time cam gears set at 0+ 0-, so no gain there, its a rebuilt engine with 70,000 miles but normally had 140,000, an intake and a muffler. Next i tend to get a custom mandrel bent cat back exhaust.
