BJSXR6TMKII Member 30 Member For: 4y 8m 29d Posted 02/08/20 11:03 AM Share Posted 02/08/20 11:03 AM Hey guys, got my 08 FG XR6T booked in for a few mods and a tune, just waiting on parts atm, mods after all is done will be, 1000cc injectors, walbro 460 fuel pump, exhaust and high flow cat, 4" dump pipe, turbo side intake, 1000hp plazmaman cooler and an external transmission cooler, it's tuned for 277rwkw atm with the fuel pump, exhaust, HF cat and dump pipe, was wondering what the turbo will max out at and if it's possible to make 340-350rwkw on a stock turbo, if not and I chose to upgrade the turbo what other supporting mods would I be up for, cheers Link to comment Share on other sites More sharing options...

I'm still learning myself but these are the things that you will probably want to change to aftermarket if you want a bigger turbo / more power.
