Hello , thank you for all your answers and solutions. I’m now running a 1.5 litre 3SZ-VE engine with turbo now. I did blown up 1 transmission while my car is still NA . After I boosted it then now ended up another blown transmission . I was thinking about 4AGE C56 manual transmission conversion too but my mechanic said that there are many parts to modify . Do you know any parts do I need to modify to fit into my car ?
