an st183 is a GT-R front wheel drive 4 wheel steering celica right? I thought those were NA cars? Yours is turbo? 3SGE engine right? essentially an ST182 but with 4ws? is your car swapped?

Add a good boost gauge then add a manual boost controller. You will have to mod you fuel cut off to not shut off at 12psi, Do a search or go to alltrac.net and read up on mods..

Good Luck
