I bought a 2.5 engine/transmission from a 1992 labaron. The engine will go into my 1986 Chrysler Laser. Is there any problems i will face during the install. I will use my 3-speed auto that is presently in my car and I'm going to use my throttle body. Hopefully this engine is ok, my 2.2 only has 96,000 miles on it but only has around 110 psi compression. It has been popping back at low to midrange speeds under load. It has new plugs, cap rotor and coil.
