11:1 pistons ftw
blockguard, MLS headgasket are a must while doing swap


have you done any headwork?

if you wanna really gain times at the track, and really build a decent N/A auto...REBUILD YOUR TRANNY FIRST

your tranny now isn't good for much hp right now, so upgrading it will provide an excellent foundation you can do the rest of your mods from. Then I would buy the Supra stick, so you can change shifts points and shift pressure, than do headwork. After that, if your not satisfied, go for a bottom end rebuild...

all my mods are: i/h/e, bsr, jwt cams, wrp underdrive pulley, tbs, ims(dont laugh, my mpg goes up almost 1 mpg with it), safc-2, ported tb/im...tjose are just my engine ones.  i want to do my tranny, but if the tranny can hold around 225-250 whp, i  should be fine...  im not adding no2.  i want to see a fully bolted auto b15 crack over 200 whp, i want to be the 1st

the tranny isn't good for that much....225 is what I was told is the max...are you tuned? I would just do a little headwork (exrtude hone or P&P, JWT springs), then get a tune, if I did anything to the motor...

and redoing the tranny isn't just for power...

I recommend doing this if anything honestly, you can change shift points and how hard your car shifts, which will help immensely at the drag strip. It will improve the car better than any pistons could. And you can also utilize the JWT springs...if you get them

trust me, for your car pistons aren't the way to go, tranny work, then headwork and tune...if you wanna be the quickest N/A AT, do it
