I am thinking of putting a turbo in my xB, but I need to know before I do it if I need a new transmission! I know that I need bigger fuel injectors, but I have had mixed feedback on this issue. Some say that I can use my stock transmission and others say that I must upgrade it! At this point I don’t want to spend money on the turbo system till I know if I have to spend even more money on another transmission! PLEASE HELP!

Please don't post the same thing in multiple forums.

the stock trans is fine... you must upgrade your clutch and pressure plate... there is a 6-speed trans that is almost bolt-on, requires a little modification to the bell housing and a little finess but toyota makes one to fit.

you will need the 1.8Litre toyota MRS injectors they are 260cc, the stock ones are 200cc, you should look into the ZPI F/I cylinder head and pistons also. If you plan on putting a lot of boost on it you may want to find some bigger injectors
