I love me Celica.. but i think its time for my turbos to be upgraded. I am facinated about the GT35 turbo kit but... is it worth the pound? anyone know what kit tufy put in his car? My bf has an STI.. but doesnt deserve it, his shifting is embarrising.. almost broke up with him b/c of it .. but anyway i want a kit that will rival it or pass it

What other modifications do you have on your car? Just putting on a big turbo isnt the ideal solution to making the car go faster. If you have on a standard ECU then you wont be able to run more than 1.2 bar as you will hit fuel cut (For the love of god do not buy a fuel cut defender, they are bad news).....if the engine has standard internals, then you will be pushing you luck beyond 1.3 bar.
The standard turbo is fast spooling and will run well at around 1.1 bar. Dont waste your money on a turbo without the supporting mods.....first off as mentioned get yourself a good electronic boost controller....an Apexi AVCR would be a good choice...a bit more complex than most others, but well controllable and will certanly give your car a bit of a kick. Beyond that you`ll want to look into cooling mods....a stand alone ECU etc...but dont forget about suspension....a well set up car can often out perform a more powerfull car.
