OK,
I have always had an obsession with the trd 3kr engine from back in the day, realised I was never going to get a real one so I decided to build my own.
I don’t recommend this conversion to anyone I did it just to be see if it could be done. It took a lot of time and if I was not a fitter/turner a lot of money.
Hope you find it as cool as I do.
