Leme preface this with i know this was discussed again less then a week ago but ive been looking for a half hour with search and all and still cant find what I wanted. Someone mentioned an actualy 6 speed trany that reduced 1/4 mile times 1 second. What was that? Im just looking into this for potential/curiousitys sake. To truly utilize the potential of 6 speed tranny wouldnt one need a new ecu as well? I was thinking for all thoes getting turbos for their 7AFE it would really be a nice feature! *trying to weight potential of swap vs turbo still smile.gif* Thanks guys

Why will they need to be changed?  I don't see why the valves would hit the pistons, but I will go look.


EDIT:  Go here http://www.club4ag.com/faq%20and%20tech_pa...%20and%207A.htm

"Conversion to the 7A-GE hybrid need not be as complicated as the 5A-GE.  This is because the block internals need not be torn apart and modified."

You may be right, but they didn't mention anything about custom rods and such.

That page refers to a 16 valve 4A head... the 20V head will require changing the pistons, so therefore, changing the rods... There are only 4 grooves on the 7A piston... even though it's fairly unlikely that the valve could hit the piston, it'll cause bad compression and will run pretty crappily... If you simply look at and compare the top of the 2 piston heads, 16V to 20V you'll understand...hopefully.
