3VZ-FE Option
"This is old news to Camry guys but a 3VZ-FE return fuel rail system will bolt right on to 1MZ-FE. this set up gives you the regulator, lines etc.. just bolt on. you can probably get one from junk /core motor at a yard for cheap. ...if you have a turbo and still have fuel line it will bolt right up. otherwise (non-Turbo owners) you will have to have new hose crimped on. The rails from a 94-96 1MZ-FE will have full return style system and your MR2 return line plugs right in.

hi brad,great thread,however the above is totally wrong,a 3vz return style rail will not work on a 1mz,we nearly had an engine bay fire due to reading this on the old board and giving it a try.The rail fits,but it cranks the injectors over at an angle and fuel squirts out everywhere,theres a good 5-10mm difference in the injector hole spacing in the rail between 1mz and 3vz.Please guys nobody do this mod,it 100% doesnt work and we very nearly lost a car.... for a return style on a 1mz go tap your rails out which is what ive done,doesnt cost much.
