yea bit of jibberish there ...
EF computer will NOT like ED chip ....
chaging compression doesnt neccessarly mean changing pistons, you can increase compression ratio by decking the head, or decreasing compression ratio by using a spacer (evil)
I wouldnt even start mix matching piston, conrods and crank gear between engines ... just keep the bottom end in one piece ...
Just do the following:
- DEV5a head (ED) onto EF block
- swap over timing gear
- bolt DEV exhaust onto EF
- buy new chip for EF computer and use the rest of the EF gear
what u need to buy in addition:
- head gasket
- intake gasket
- exhaust gasket
- EF chip (not sure if u even need that one but what the hack)
thats probably gonna be much simpler and more efficient than swapping the entire engine. You probably find that the EF bottom end is in good nick, just that the EF top end is getting old.
Dunno about bolting ED tranny into EF, as far as i know they use different shifting programs, but i know that CAPA is offering shift kist for the EFs for around 375 bucks, which probably gonna improve the shifting a lot. And if u feel like spending some more $$$ get a newer/higher stall convertor.
Thats would be my plan of attack
