So I want to build my 7a with a little higher compresson (11-12:1) for a slight power increase and a nice increase in efficientcy and 'peppiness.' Upon searching I found little to no information about where I can get a set of high CR pistons w/o having to mod the rods and whatnot. So does anyone know who, if anyone. caries a higher CR piston for the 7a? If not, where i can get a good set of customs from? This is on a spare 7a so no big deal if i have to wait/ship my stock pistons. And does anyone know about rod bolts? I know thats one of the 7a's weak spots so if ARP has any bolts to fit that'd be great, or if anyone knows of some stronger bolts... I like to beat my engines so it'll have to be strong enough to handle my habits.
 shorthand: 1.) Where can i get higher CR pistons for the 7a? (11-12:1) 2.) How can I beef up my rods/rod bolts? 3.) Don't flame about my building choices, I went this way for a reason. -------------------- QUOTE "And, as always, your friendship, help, and dedication to the advancement of Texas Celica dominance is GREATLY appreciated.

7a has more torque at lower RPM, and better economy.
This 7a is going in my daily, so I want the nice low RPM torque and the 30ish MPG. 4age's do not have those qualities. For my power celi my GT will have a 3s soon -------------------- QUOTE "And, as always, your friendship, help, and dedication to the advancement of Texas Celica dominance is GREATLY appreciated.

For my power celi my GT will have a 3s soon well when you bump your compression up your mpg will go down plus youll have to run higher octane gas to aviod knock not on 100% on this but could do a couple things buy 4ag high comp pistons also maybe deck the block and or shave it. To up the comp imo if you want to keep the mpg i wouldnt really do anything to up besides maybe a p&p and clean it up -------------------- yea your 3sgte is cool but ill stick to my 7agte
