Sorry for not being clearer 1jz engine tuning. I have the usual mods that you speak of. i want to up the boost to 1.4bar but some guys say I need 2jz injectors, bigger fuel pump, cams upgraded, etc etc. I need advice on how far i can go on stock internals without doing damage and also if I need a bigger turbo.
