Celica Forums General Discussion Engine and Performance What does the GT like?

Alright, I'm lookin at a few of you for answers here:
I've got an overall idea of what I should or should not do to my car (02 manual), and what will keep my gas mileage. Obviously, without F/I, the best addition to the Celica GTS is the Power FC... What about the GT? This could be a very valuable thread for anyone, so make it factual while throwing in your opinion

1) Performance-relative, what is the best addition to the GT? (sans F/I)

2) Power FC or E-manage? Ellaborate why.

3) I/H/E, horsepower gains decrease practically at an exponential rate as you put on each of these. Would you buy all three? If not, what two would you combine? Which brands?

4) Note any other additions that can complement your 0-60 and 1/4 times.

crower makes some n/a cams that would help alot

also put an lsd in to help with traction and ur 0-60

some good tires will help alittle

pistons, rods, ect.

yeah, we need some more answers..

1)Suspension

2)E-manage, don't get me wrong PFC is superior hands down, but tuning the 1zz A/f maps won't turn over much HP, so e-manage is a cheaper almost as efficient solution.

3)I'd buy I/E, makes the car more peppier and more responsive.

4)weight reduction and some sticky tires.

the GT is a very fun car for road racing or autoX.
