I had the same problem when purchasing my car...I was pretty pissed that Turbos came out wwwaaay earlier for the GT than the GTS...I also was worried not to much on the warranty but more on the reliablity and long lasting of my motor if i was to go Turbo...
TOP 10 Reasons why I bought a GTS instead of a GT
#1> Faster than GT (stock)
#2> Six Speed Tranny is nice to have
#3> Rear Disc Brake (ABS) but if your not going for the show look, it dosent matter
#4> Driver and Passanger Side Air Bags
#5> GT and GTS has Turbo kits out on the market but I havent found a "complete kit" for the GT.. actually the closest for GT would be the DA or stafford but then again i am talking about "COMPLETE" and DA has a Piggy Back ECU (as i was told) as for stafford im not to sure...not mentioned more likely a piggy back or reprogramming of your ECU...GTS has a complete kit out right now by XS Engineering which i think is the most reliable Turbo for the GTS which is available
Turbo kit consists of a ball bearing IHI VF23 Turbocharger, a huge 24"x11"x3" XS Engineering Power IC, durable cast iron manifold, and APEXi Twin chamber blow off valve, full stand alone fuel management, consisting of 504cc injectors, 255lph fuel pump, and an XS Engineering tuned APEXi Power FC.<<<<<
#6> I know I know...its only 250hp at the wheels and boosts only at 8psi<<<<
#7>but then again http://www.jrponline.com/gallery/gts.asp
is coming out with a Turbo with 297 hp...@ the wheels<<<<<<
#8>GTS is more compact...
in the engine compartment. lol
#9> GT stands for GOT Turbo?
GTS stands for GOT Turbo SUCKA?
#10> All in All no matter what you get...Its a CELICA...
