[CeliNProgress]

What up everybody? Im a new comer and I gota situation on my hands. I've had my Celi a lil more than a year and now I got a problem I need to deal with IMMEDIATELY!!! Due to certain circumstances my celica ST wont drive. Its a long story. Anyways, I either need to rebuild my motor or swap it out and drop a MR2 in it. If I rebuild Im going all the way. Port and Polish, Valve Job, New Springs, Lifters, Etc. So I already talked to my friend's dad who works at Toyota and he would dothe swap. But no matter what I do I wanna be TURBO! For you to get a better understanding there's a nut in my motor and it'll turn on but shut off after a little bit of running. You can hear it bouncing around and then the noise goes away and then you can hear it again. My boys and I think it's in the valves???? Don't really know. If you guys can throw in your input and help me out I would really appreciate it. Aight 1
