Hey guys. I have a 2018 STI that I’ve Been working on for about 2 years and here is my current Engine mod list.
Cobb intake
Cobb accessport
Nameless turbo back exhaust
AEM high flow fuel pump
Cobb flex fuel sensor kit
Cobb fuel rails
Cobb 1050 injectors
Flex fuel tune
333WHP/360T

Just trying to get some ideas about what to do next to get closer to that 400WHP area or just above it and try to get there safely. My goal is to build a pretty quick car but still keep it reliable to drive around town / on road trips. It will be more of a show car.

What are some ideas for the next set of performance mods? Would a turbo kit or cams be the better route?

Also at what point do i consider getting parts that help keep temperatures down or help with preventing any expensive breaks like a transmission fan, Turbo heat shield, catch can, rods etc. i hope this is all making sense. Thank you for your feedback its much appreciated.

For performance mods i think you should add ELH. You will see some real nice gains especially with E85 but it still wont put you at 400whp. You will need a larger turbo to get there and you may want to consider a built block at that point too.
