I have an ST, but as we all know they are extreamily slow stock...i would love to put a different head on it but theres 2 problems...1) i have no idea which one would make the best/most amount of power and 2) how hard it would be and where i could get a new/used head at....would i be able to use a head off of a GT and if so what other options would i have to make even more power, im sure there are more heads i can use?..im not to sure how common of a mod this is but i would love to do it...any feedback at all would be great so i can get some ideas together...thanks!

unlike the hondas, switching heads on the celica is not that easy.
the "A" series, and "S" series egines are totally diffrent designs. ones a 1.8l the other a 2.2l there are a couple other A series heads that you can get to fit on the 7a block IIRC, but i dont know much about which ones, as i have a GT. -------------------- Former Team 5SFTE pro member ;)

I was under the impression that putting a larger head on would require a standalone to run properly? Can anyone shed some light on this?

yes you will need to use a stand alone engine management to run properly.

I believe any of the 4age heads work with the 7afe block.
you have many choices, 4age, 4agze, 20v.... ect ect QUOTE(Hanyo @ Jun 2, 2007 - 7:40 PM) [snapback]564305[/snapback] yes you will need to use a stand alone engine management to run properly. search! http://www.6gc.net/forums/index.php?showtopic=17020 Before you ask another question, answer this one: do you plan on adding force induction to your build?

QUOTE(stephen_lee @ Jun 3, 2007 - 7:30 PM) [snapback]564474[/snapback] its been done. not that easy, but possible. On the contrary... it's been done a LOT and it's not too hard. Just imagine a 4AGE swap with a 7A block. Not too difficult... but then again... how many people have 4AG swaps... The 7AGE will run perfectly fine on the stock 4AG ecu. The price and difficutly in the end depends on how much you know, and how far you want to go. nik's cost significantly more than the average because he built a boot purpose motor. The 7AGE build can be done with stock parts... but be warned, the MAJOR weakness is the 7A rods which won't last long past 8000 rpms and they will require machining to match the pistons. You guys should google some of this stuff and learn the basics before anything however... -------------------- "It's ok to be naked girl... I'm an artist!"
