my 2.8 diesel 4runner, Running really smooth. Have just done the timing and put a new head gasket in. Aslo just put a new heavy duty clutch in. i have put the seats and doorpannels from an sr5 so the cabin is looking pretty nice. i also have a set of OME 901s that i am going to put in soon. What are some cheap mods for 2nd gens?
