I have a 95 Ls Pickup with 4JA1 engine, no problem so far. tried to ask a couple of mechanics to overhaul, ayaw buksan. except for the usual usok. Normal lang daw yung white na usok. hehehe. Problem nga yung mga nang huhuli ng smoke belching. Btw, does anyone know kung ubra mga kabit ng turbo sa stock 4ja1? Anu con's and pro's on having it? How much does it cost?
