i've been to new iberia several times
good luck with the supercharger project. the first gen mr2's use a different engine than the 1zz your celica gt uses so you'd have to do something custom as mike (lucky_317) said. TRD
does make a supercharger for your cars ENGINE though..although it won't fit under your Hood
. you'll have to get your hands on a super-rare 'bubble' Hood
(i'll post a pic). other than that..there are no superchargers made specifically for the supercharger engine.
the power fc will set you back about $1,000. custom mounts will set you back almost that much as well. in the end you will still come out ahead because its a free supercharger..but that doesn't mean you can just plop it in there at no cost.
good luck on everything..and stay in touch with the rest of the louisiana peeps in the southeast forum
