Have a question that I'm hoping will go in a good direction. But who knows, so I'm over here in America so idk what the conversion of miles over is. But I just bought a 97' eclipse GS with the 420a motor in it. And yes. Completely stock, and compression is still perfect. But it should be for only having 59,000 miles on it at 17years old. And I checked to make sure it wasn't rolled back and nope. It's original miles. So a couple questions, is it worth to turbocharge it? And what risks am I taking? And I know the century old question. Is it work keeping the PCV valve on it. Or adding a breather? Always has mixed feelings about that but I wanna hear it from you!
 
You should search around this site for turbo-ing a 420a. Most people say no, some might say yes and by some I mean a few. Everybody has there own direction for their builds, so look into it a bit and see if it's right for you. But one thing I do know is that it costs decent money for a properly built turbo 420a. You will get all the info you need about it on this site though.
 
It doesn't really mater about the mileage of the engine if you plan to turbo it because you are going to have to completely rebuild it to handle the boost. While its stock you should leave the PCV.
Alright will do, but plan on changing stuff soon. But I mean I added the milage just for reference :p
