LOL well it seems pretty clear to me that s4s and atleast springs and retainers are a good choice for you as you will definitely take full advantage of them up top in the rpm. and drive shaft is out of the question till u decide on the tranny i guess so the only other thing i can suggest like i said are supporting mods like maybe a engine oil cooler with a thermostat if your gonna be ripping on it that high of a rpm all the time itd be good to keep the oil a little cooler for the bearings. Also maybe a water/meth kit? both of those will never get old and will help you run more hp safely.
Oil cooler with a thermostat has been thought about, but I kind of pushed it out of my head for some reason. Need to look into ordering one.
Water/Meth injection I haven't thought about. I need to do some research on that, not really sure how they work.
This is my first turbo car lol, I'm about 4-5 months into it. I'm used to modded 1000cc street bikes and 195mph on the limiter in 5th gear. So I need a good bit of power to keep me interested.
