hi, new to the forum, just bought a 1992 toyota mark II saloon with a 2L-T 2.4 turbo diesel, keen to eventually do a swap to a petrol engine (1jz or 7mge) does anyone know hoe much this would cost, how long it would take?, probably buy a wrecked cressida and use the engine and parts from it, so diesel to petrol conversion worth it or not?
