JZA 70 owners?

[neoman]

Hi all. just wondering if there are any other Jza 70 owners here. Would like info on tuning the 1JZ engine.

believe it or not most jza70 owners used to be ma70 owners, so you're not looking "just" for jza70

and tuning... well it's the same as any car really
exhaust, filter, boost, intercooler, pipes etc etc

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.

get a jdm 2jz map sensor & install jdm 2jz injectors & get a walbro, then up the boost to 20psi
but if you wanna play with 20psi i highly recommend you get your turbos rebuild and steel wheels put in or you go max 16psi ish as the turbos aren't reknowned for hanging on at high boost levels
