is it hot in kewait,the origional test on this vehicle stock was done at sea level or slightly below sea level,and at an optimal 60-70 degree f .if you are opperating this vehicle in a very hot environment then you will suffur from a hot air charge entering your intake thus taking power from the engine.if an 87' supra weighs 4460lbs see if there may be hidden gold in it say 1000lbs worth.this vehicle cannot weigh that much.my old 87' n/a supra weighed about 3500 stock.my other suggestion on why your so slow is that maybe these second hand motors are all garbage.sorry to say it but i did a 1jz-gte conversion to get away from the problems of the 7m.however built correctly(prefferably built by your own hands so that no one can b.s you on what work has been done to the engine and the condition it is in)is very dependable.i can't stand paid mechanics most of them are are "parts changers"most can't troubleshoot without holding the diagnostic machines hand(thats why i've struggled to learn to do it all myself),after all if you want a job done right,you got to do it yourself.have a great day,laters!
