help me please
 

i have an 88 turbo, manual. i have recently put on a bride steering wheel, a momo shift knob, and it already had exhaust done when i got it. i also recently put on the trd version of the mushroom style hks filter. it's lowered (i'm not sure how, i haven't gotten under it to look yet) and it's currently at the shop getting an exedy heavy duty clutch put in.

i have a few questions, because i used to be a dsm guy, and i am new to supras, but definitely not new to turbos.

i'm wondering what mods i should do first...also, what are the free things you can do to mod the car (i.e. washers on the wastegate to up boost), and i have an hks supersequential bov and the flange, but i don't even know where the stock blow off valve is, so i have no clue how to install the one that i have. also, i got offered a really good deal on a buddy club seat recently, and i'm wondering if it's worth it weightwise and moneywise to get rid of the electric adjustable seat.

it also has a few problems that i'm really curious about how to fix, but that's a whole different story. just some electrical thing with my rear wiper, and one brake light doesn't work, but only when the headlights are on, otherwise it's fine.

i would also like to say that i have fallen in love with the inline six, the sound, the feel of it, everything. these are great cars. i'm pretty sure if anything ever happens to this one, i'll get another one. thanks in advance for your help everyone!

congratulations on owning a supra :D
