I've got a 1979 RA40 (round headlights) Celica and my 18R motor is on its last legs with compression problems. I've recently found a Recond. 18RG with a w50 gearbox. How easy would this be to drop into my RA40, and would I need the w50 gearbox, or is it just an extra. Other extras being sold with it are a toyota supercharger, intake manifolds, extractors, pulleys, and standard intake manifolds with 2 40mm Webers. How much would it cost to firstly, drop just the gearbox and engine into my celica, and secondly, how much would it cost to drop it all in? I still want my car to be a daily driver, but i want a little extra oomph too. I'm a 19 year old student so insurance costs and installation costs are a prime factor. Can anyone help me out?
