i have my sol with a y8 head on a d15 block n/a. i'm installing an t3 turbo setup and i would like to know if i'm better of using a dx tranny? or should i stay with my ex tranny on??? also i want some info on the g23 build up (h22 head on a f22 block) basically has anybody done this swap??? especially on a del sol. i plan to go boost on it since that build without k20 pistons is on low compression. I read the build on import tuner. now whats the difficulty on it and is it worth dropping into my sol????
