[NYcelica]

I'm new to this whole toyota thing. i just got a red 1990 2.2 Celica GT. I fix all the little thing i could.....
up the timing ,cold air intake, new alternator, clutch, plug & wires , tires , IAT sensor override
but it still slow lol , well i guess not for what it is .. maybe it because i drove a 4.5L q45 for so long.

so i trying to squeeze as much power out out of this thing as i can and want to know how hard i will be to turbo this motor .or how hard it is to do a swap it with a GTS motor.
maybe a few links or something

thanks
