    What turbo should i use

    so I have a 03 wrx, and I have all the supporting mods to run a 20g turbo. I have the 20g on a brand new reman ej20. I've been reading that 20g has quite a bit of lag and im wondering if I should just go back to stock. I also read that it makes your tranny go faster. I have a 04 5spd tranny in it. I just wanna be really fast on the street and be able top keep up with people at the track and do autocross every once in awhile. please help. also note that I haven't ran it yet ive only started it. im figuring out vacuum leaks right now and get that squared away before I drive it

    The ball bearing 20g I had was hitting full boost at 4050rpm.. but that was on a 2.5L block. As far as the transmission holding up, that's all up to how you drive it. It will certainly be easier to break it with more power.

    A TD06 20G will have a lot of lag, especially on a 2.0... and most of your power will be high end

    A TD05 20G will have significantly less lag, and will provide better low-end power.

    What do you have?
