so u guys think tell me if im wrong. buy a supra tt, "bpu" it out (exhaust, downpipe, boost controler,ect.) i looked under the "bpu" site and i was wondering if i got a supra tt should i replace the turbo. oh and does the tt cum wit an intercooler. shud i upgrade anything else, like in the cooling system. like the water pump, radiator,ect. is a boost controler like a guage like a tach or is an actual cpu? oh and suspension wise is there anything that needs to be upgraded beside lowering.
