i have been doing research all week. although i would love to boost this little puddle jumper, i just dont know if its a headache i want to deal with right now. although the ebay "tuner kits" are conveniently priced under $1000 and include just about everything you need, less the manifold and downpipe.

just about every post i've seen for the NA 7A, recommends swapping to a G series head. Boring out the cylinders to 82mm would allow the 2ZZ pistons to slide right in, and i just discovered that they now offer 13:1 pistons for the 2ZZ. The new head and HKS cam gears require swapping the timing belt with one from a porche. i dont have it right in front of me which one, but it is in my records. There have been several people who have done this conversion already, however none who tried the 13:1 piston or extreme cams. i plan to use the same methods with the air and fuel as i used on my 98 ford contour zetec. after tripping the CE light with the air flow, the new 5th injector was just enough to straighten that out plus the new straight through exhaust makes an impressive improvement over the OE 110hp. returning to the celica, with a dry sump oil pump, custom IM, bigger throttle body, and a whole lot of hard work and tuning. i believe i can bring a +250hp 7a to the table.

on the other hand........... it could just snap craccle and pop when i try to start it...... that would succ
